Security deposit limit
1 month's rent per dwelling unit, regardless of the number of tenants. Up to 2 months' rent is allowed only if the tenant qualifies for Department of Human Services utility assistance, the lease requires the tenant to pay utilities directly to the landlord, and both agree in writing. A landlord who charges more than the cap can be sued for up to 3 times the extra amount plus reasonable attorney's fees. Md. Code, Real Prop. § 8-203(b)(1)-(3)

Within 45 days after the tenancy ends, the landlord must return the deposit plus accrued interest, less damages rightfully withheld. Md. Code, Real Prop. § 8-203(e)(1)
Notice for unpaid rent
Before filing a failure-to-pay-rent case, the landlord must give the tenant written notice of intent to file (Maryland Judiciary form DC-CV-115) giving the tenant 10 days to pay. Notice may be sent by first-class mail with certificate of mailing, affixed to the door, or (if the tenant elected it) by email, text, or tenant portal with proof of transmission. The complaint must state the date notice was given. Md. Code, Real Prop. § 8-401(c)
Ending a month-to-month lease
Landlord: written notice at least 60 days before expiration for month-to-month tenancies and leases for a stated term over 1 week; 90 days for year-to-year; 7 days for week-to-week with a written lease (21 days without one).

Code, Real Prop. § 8-221
Rent control / increase limits
No statewide rent control or statewide cap on rent increases. Local jurisdictions may adopt rent regulation (statewide preemption not found). Md. Office of the Attorney General, 'Landlords and Tenants: Tips on Avoiding Disputes' (Rev. Feb. 2025); DHCD Tenants' Bill of Rights (eff. Oct 1, 2026)

Main law: Maryland Code, Real Property Article, Title 8 (Landlord and Tenant), esp. Subtitles 2 (residential leases) and 4 (repossession/eviction) — Md. Code, Real Prop. §§ 8-101 et seq.; §§ 8-203, 8-208, 8-208.1, 8-211, 8-216, 8-221, 8-401, 8-402, 8-402.1, 8-407

Security Deposits in Maryland

Security deposit limit1 month's rent per dwelling unit, regardless of the number of tenants. Up to 2 months' rent is allowed only if the tenant qualifies for Department of Human Services utility assistance, the lease requires the tenant to pay utilities directly to the landlord, and both agree in writing. A landlord who charges more than the cap can be sued for up to 3 times the extra amount plus reasonable attorney's fees.
Cap reduced from 2 months to 1 month by the Renters' Rights and Stabilization Act of 2024 (HB 693), effective Oct 1, 2024. The DHCD Tenants' Bill of Rights (effective Oct 1, 2026) says deposits up to 2 months' rent remain valid for leases signed before Oct 1, 2024. Separately, a landlord may not require more than the security deposit plus the first month's rent before move-in (§ 8-208(d)(11)).
Deposit return deadlineWithin 45 days after the tenancy ends, the landlord must return the deposit plus accrued interest, less damages rightfully withheld.
A tenant who was evicted or abandoned the unit before the lease ended must mail the landlord a written request for the deposit within 45 days of leaving. The landlord then has 45 days from that notice (per DHCD Tenants' Bill of Rights and AG guide).
Itemized deductionsWithin 45 days after the tenancy ends, the landlord must send a written list of damages claimed plus an itemized statement of the cost of each (with supporting documentation; cost estimates allowed) by first-class mail to the tenant's last known address. If the landlord does not, it forfeits the right to withhold any of the deposit for damages. Where estimates were used, the landlord must notify the tenant when repairs are done and refund any excess within 30 days.
Move-out inspection right: if the tenant notifies the landlord by certified mail at least 15 days before moving (giving move date and new address), the tenant may attend the inspection, which must occur within 5 days before or after the move date. Failure by the landlord to comply forfeits the right to withhold for damages (§ 8-203(f)).
Interest on depositsRequired. Simple interest accrues monthly from the date the deposit is paid. The rate is the greater of the 1-year U.S. Treasury yield-curve rate as of the first business day of each year, or 1.5% per year. No interest is owed unless the landlord held the deposit at least 6 months, none accrues for partial months, and it applies only to deposits of $50 or more.
DHCD publishes a Rental Security Deposit Calculator and rate list that landlords may rely on (§ 8-203(m)-(n)); it is linked from the DHCD Office of Tenant and Landlord Affairs page.
Penalty for withholdingIf the landlord fails to return the deposit and interest within 45 days without a reasonable basis, the tenant may sue for up to 3 times the withheld amount plus reasonable attorney's fees.
Deposit provisions cannot be waived in a lease (§ 8-203(l)). Landlord must give a written receipt for the deposit, included in any written lease (§ 8-203(c), § 8-203.1).

Eviction in Maryland

Notice for unpaid rentBefore filing a failure-to-pay-rent case, the landlord must give the tenant written notice of intent to file (Maryland Judiciary form DC-CV-115) giving the tenant 10 days to pay. Notice may be sent by first-class mail with certificate of mailing, affixed to the door, or (if the tenant elected it) by email, text, or tenant portal with proof of transmission. The complaint must state the date notice was given.
The 10-day pre-filing notice was added by 2023 legislation. DHCD's Tenants' Bill of Rights notes that longer notice may be required for tenants with state- or federally-funded housing subsidies, and that in a failure-to-pay-rent case 'rent' means base rent only, not utility or maintenance charges or penalties.
Notice for lease violations30 days' written notice that the tenant is in violation of the lease and that the landlord wants to repossess; 14 days' written notice if the breach involves behavior showing a clear and imminent danger of serious harm. The court may evict only if it finds the breach was substantial and warrants eviction.
Appeal to circuit court must be filed within 10 days of judgment (§ 8-402.1(b)(2)).
Lockouts & utility shutoffsProhibited. A landlord may not take or threaten to take possession by locking out the tenant, willfully cutting heat, running water, hot water, electricity, or gas to force the tenant out, or by any other action. Possession may be taken only under a court warrant of restitution executed by a sheriff or constable, or after abandonment/surrender. Remedy: actual damages plus reasonable attorney's fees and costs; other remedies also available.
No fixed statutory damages amount. Landlord may temporarily secure an unsecured property (including changing locks) if it makes good-faith efforts to notify the tenant they may be promptly restored to possession (§ 8-216(d)). Leases may not allow taking possession or the tenant's property without legal process (§ 8-208(d)(6)).

Notice to Vacate in Maryland

Ending a month-to-month leaseLandlord: written notice at least 60 days before expiration for month-to-month tenancies and leases for a stated term over 1 week; 90 days for year-to-year; 7 days for week-to-week with a written lease (21 days without one). Tenant: at least 30 days' notice (90 days for year-to-year).
Statute allows a tenant to give oral notice (provable by testimony); DHCD's Tenants' Bill of Rights advises written notice. The tenant-notice paragraph does not apply in Baltimore City, where per DHCD tenants need give only 30 days' notice to end any tenancy unless the lease requires more (Baltimore City Public Local Law § 9-16). If a small landlord (fewer than 5 units, outside Baltimore City and Montgomery County) has received a notice of intent to foreclose, shorter notice applies: 30 days (month-to-month/week-to-week) or 60 days (year-to-year) (§ 8-402(c)(4)). Farm tenancies differ (180 days). A landlord that has already given notice of termination is exempt from the separate rent-increase notice rule (§ 8-209).

Landlord Entry in Maryland

Landlord entry noticeWritten notice at least 24 hours in advance stating the approximate date/time and specific purpose; entry only 7:00 a.m.-7:00 p.m., Monday-Saturday, unless the tenant agrees in writing to another time or shorter notice. Permitted purposes include repairs/maintenance, inspections, showing the unit, safety, government-ordered work, and responding to a written tenant request. No notice needed in an emergency.
Enacted by 2025 Md. Laws ch. 564 (HB 1076), approved May 13, 2025, effective October 1, 2025 (https://mgaleg.maryland.gov/mgawebsite/Legislation/Details/HB1076?ys=2025RS). Notice may be mailed first-class with a certificate of mailing, posted on the door, or sent electronically if the tenant chose that method. Remedies: injunction and/or damages for breach of quiet enjoyment. A tenant alleging a housing code violation must allow access within 24 hours after notifying the landlord (§ 8-221(f)). A 2026 bill to allow entry without notice for tenant-requested repairs (SB 635) did not pass.

Repairs & Habitability in Maryland

Repair and deductNo statute
Maryland's statute provides court-supervised rent escrow rather than self-help repair-and-deduct. The AG's guide warns that withholding rent outside the escrow process risks eviction.
Withholding rentRent escrow. If the landlord fails to fix serious conditions (lack of heat, light, electricity, hot or cold water; inadequate sewage; rodent infestation in 2+ units; dangerous structural defects; fire or health hazards) within a reasonable time after notice, the tenant may file a rent escrow action and pay rent into court, or withhold rent and raise the conditions as a defense to an eviction. Notice can be certified-mail written notice, actual notice, or a government violation notice. More than 30 days after notice is presumed unreasonable.
Court may abate rent (rebuttable presumption of abatement of prospective rent), order repairs, terminate the lease, or release escrowed funds for repairs. Barred if the tenant has 3 prior rent judgments in the last 12 months (monthly tenancies; different limits for weekly), or if the tenant/guests caused the defect or denied access. Prevailing tenant may recover attorney's fees (§ 8-211(o)). Cosmetic defects and lack of air conditioning are presumed not to qualify (§ 8-211(e)(2)), though DHCD's Bill of Rights notes a separate A/C requirement for certain buildings with 10+ units. Baltimore City has its own very similar rent escrow law (AG guide); § 8-211(q) lets more-protective local laws stand.
Retaliation protectionLandlord may not bring or threaten a possession action, arbitrarily raise rent or reduce services, or terminate a periodic tenancy because the tenant made a good-faith complaint (to the landlord or a public agency) about a lease/law violation or a substantial health or safety threat, sued or testified in a suit involving the landlord, joined a tenants' organization, or called police/emergency services. Remedy: damages up to 3 months' rent plus reasonable attorney's fees and costs.
No presumption period. An action taken more than 6 months after the tenant's protected act is not retaliatory (§ 8-208.1(e)). Tenant must be current on rent unless lawfully withholding (escrow) (§ 8-208.1(d)). Bad-faith tenant claims can result in fees awarded to the landlord. State law overrides any less-protective local ordinance (§ 8-208.1(g)).

Rent Increases & Late Fees in Maryland

Rent control / increase limitsNo statewide rent control or statewide cap on rent increases. Local jurisdictions may adopt rent regulation (statewide preemption not found).
Rent-increase notice is statutory: written notice at least 90 days before an increase for tenancies over 1 month, 60 days for tenancies over 1 week up to 1 month, and 7 days (written lease) / 21 days (no written lease) for weekly tenancies (Real Prop. § 8-209(b)(3)). Local rent stabilization exists in Montgomery County: for July 1, 2026 – June 30, 2027 the allowance is 5.2% (the lesser of CPI-U + 3% or 6%), Montgomery County Code §§ 29-57, 29-58 (https://www.montgomerycountymd.gov/department-housing-community-affairs/rent-stabilization/rent-stabilization-increases-limitations). Takoma Park and Prince George's County also have local rules; see the county pages.
Late feesCapped at 5% of the amount of unpaid rent for the rental period. For weekly rent: no more than $3 per week, with a total of no more than $12 per month. No statutory grace period.
Lease terms exceeding the cap are unenforceable (§ 8-208(g)). The AG's guide notes a grace period may come only from the lease or local law.

Breaking a Lease in Maryland

Ending a lease: domestic violenceA tenant who is, or whose legal occupant is, a 'victim of abuse' may end future lease liability with written notice of intent to vacate, sent by first-class mail or hand delivery, stating the victim status. The notice must include one of these: a protective order, a peace order based on abuse, or a qualified third party's report signed within the past 60 days with the alleged abuser's name and description redacted. The tenant has 30 days to move out and owes rent only from the notice date until move-out, up to 30 days. A tenant who leaves sooner must send a signed, notarized notice of vacating by first-class mail or hand delivery; the landlord must then inspect and confirm the rent owed or refund due. If the tenant has not left within 30 days, the landlord may treat them as a holdover or treat the notice as withdrawn. The abuser's liability does not end.
The definition of 'victim of abuse' (§ 8-5A-01) was not reviewed. Confirm whether it covers sexual assault and stalking. § 8-5A-03: https://mgaleg.maryland.gov/mgawebsite/Laws/StatuteText?article=grp&section=8-5A-03&enactments=false
Ending a lease: military, medical, deathMilitary: an active service member, or the member's spouse, who receives a change of assignment owes no more than rent then due plus 30 days' rent after giving written notice and proof, plus repair costs for damage. A change of assignment includes PCS orders, temporary duty over 90 days, orders to move on base, and release from active duty. Medical: a tenant owes no more than 2 months' rent after moving out if, before vacating, they give written notice with a move-out date and a certification from a Maryland-licensed physician or psychologist, on letterhead or a prescription form. The certification must state that a medical condition restricts mobility, requires a move for a higher level of care, or is a mental disorder making continued residence unfeasible. The medical rule does not apply if the lease already has an early-termination clause requiring 1 month's notice or less and charging 2 months' rent or less.
§ 8-212.1: https://mgaleg.maryland.gov/mgawebsite/Laws/StatuteText?article=grp&section=8-212.1&enactments=false. No tenant-death statute was checked.

Squatters & Abandoned Property in Maryland

Squatters / unauthorized occupantsWrongful detainer action in District Court against anyone who holds real property without a right to possession, where no landlord-tenant (Title 8) remedy applies. The court must summon the occupant at once, and the hearing must be held no more than 10 business days after the complaint is filed. If the occupant cannot be found after two good-faith attempts on different days, the process server files an affidavit, sends the complaint by certified and first-class mail, and posts the summons on the property. Service must be completed within 4 business days of filing. No counterclaims are allowed. If the owner wins, the court orders restitution and issues a warrant to the sheriff or constable. Damages, costs and attorney fees are available if claimed and the occupant was personally served. Either side may appeal within 10 days.
The 10-business-day hearing and 4-business-day service rules match the 2025 anti-squatting legislation described in news reports. The enacting bill number was not confirmed.
Belongings left behindNo statewide storage-and-sale procedure. At eviction, the warrant of restitution directs the sheriff or constable to remove the tenant's belongings. At least 6 days before the scheduled eviction, the landlord must send written notice by first-class mail with certificate of mailing, post it on the front door (with a date-stamped photo), and text or email it if the landlord has that contact information. The notice must include a statutory warning that the tenant could lose all belongings left inside and that local disposal laws vary. A lease may not let the landlord take the tenant's property unless the tenancy has ended and the property was abandoned. Disposal is governed by local law.
No state statute was found for property left behind after a voluntary move-out. Check county and city codes (for example Baltimore City and Montgomery County).

Rental Fees in Maryland

Application / screening feesThere is no dollar cap. If any non-deposit fee charged to an applicant exceeds $25, the landlord must return it within 15 days after move-in or after either party says in writing that no tenancy will occur. The landlord may keep only the amount actually spent on a credit check or other application expenses. Penalty for not returning it: twice the fee. The application must explain the tenant's liabilities and these rules. Does not apply to landlords offering 4 or fewer units on one parcel or location, or to seasonal or condominium rentals.
No portable-screening-report statute was found.
Other rental feesMove-in cap: a lease may not require more than the security deposit plus the first month's rent to start the lease and move in. Late fees are capped at 5% of the unpaid rent (weekly leases: $3 a week, $12 a month). A lease may not make the tenant pay the District Court filing surcharge assessed against the landlord, except as § 7-301(c)(5)(ii) of the Courts Article allows. The landlord may charge no more than $5 for the 6-day eviction notice. The lease must include the Maryland Tenants' Bill of Rights.
No general statewide ban on convenience or online-payment fees and no total-cost-of-rent disclosure statute was found.

Section 8, Records & Right to Counsel in Maryland

Section 8 / source of incomeYes (HOME Act). It is illegal to refuse to rent to someone, or discriminate in rental terms, because of source of income. 'Source of income' means any lawful source of money paid to or for a renter, including any government or private rental assistance and Housing Choice (Section 8) vouchers.
Exemptions in §§ 20-703 and 20-704 (such as owner-occupied buildings) were not reviewed.
Eviction record sealingYes (shielding). Failure-to-pay-rent cases that do not end in a judgment for possession are shielded automatically by the District Court within 60 days after final resolution. If there was a judgment for possession, the tenant may ask the court to shield the records. The court may do so if the tenant redeemed (paid in full) and at least 12 months have passed, or for good cause. Shielded records may be opened only at the tenant's written request or by court order for good cause. Separately, § 8-502 allows petitions to shield COVID-era nonpayment cases filed Mar. 5, 2020 to Dec. 31, 2021.
The automatic shielding reportedly took effect Oct. 1, 2024 (secondary source; not confirmed in session-law text). § 8-503 cross-references the redemption right as '§ 8-401(g)', but redemption now appears at § 8-401(h), probably a renumbering.
Right to a lawyer in evictionYes, a statewide access-to-counsel program. 'Covered individuals' have access to legal representation in eviction matters through the Access to Counsel in Evictions Program, run by the Maryland Legal Services Corporation. A covered individual is a non-owner occupant, including a public-housing tenant, whose household income is no more than 50% of the state median income, adjusted for household size.
Implementation is reportedly phased in and depends on funding. The later sections (§§ 8-904 and following) on phase-in and funding were not reviewed. § 8-901: https://mgaleg.maryland.gov/mgawebsite/Laws/StatuteText?article=grp&section=8-901&enactments=false

Mold, Pests, Heat & AC in Maryland

MoldYes, by statute (Maryland Tenant Mold Protection Act, effective July 1, 2025). Landlords must give each tenant the state mold information pamphlet when the lease is signed and on request, and ask the tenant to sign an acknowledgment. Within 15 days after written notice of mold from the tenant, a building occupant or the local housing-code agency, the landlord must do a mold assessment. If mold is found, the landlord must remediate it within 45 days after the assessment, or within a reasonable time if 45 days isn't feasible. Assessment and remediation must follow industry guidelines and state and local law. The landlord must keep the property properly ventilated with low indoor humidity, communicate with occupants during the work, and meet minimum livability codes.
Session law: https://mgaleg.maryland.gov/2025RS/Chapters_noln/CH_539_sb0856e.pdf. The Department of the Environment must adopt uniform mold assessment and remediation standards by June 1, 2027. Mold that creates a serious health hazard may also support rent escrow under Real Prop. § 8-211.
Pests & bed bugsNo bed-bug-specific statute. A rodent infestation in two or more units is a listed serious defect: if the landlord fails to fix it within a reasonable time after notice (over 30 days is presumed unreasonable), the tenant may use rent escrow. Other infestations that create a health hazard can also qualify. The state Minimum Livability Code, which adopts the International Property Maintenance Code, applies where no substantially similar local code exists.
COMAR 09.12.54.03: https://regs.maryland.gov/us/md/exec/comar/09.12.54.03. The IPMC's pest-extermination allocation rules were not reproduced on the state site and are not quoted here. County and city codes (e.g., Baltimore City, Montgomery County) often have more specific pest rules.
HeatLack of heat is a listed serious defect: if the landlord doesn't fix it within a reasonable time after notice, the tenant can use rent escrow. This does not apply when the tenant pays the utility and the lack of heat is from the tenant's own nonpayment. No state statute sets a minimum temperature. The state Minimum Livability Code adopts the 2012 International Property Maintenance Code, which contains heating standards, for housing in localities without a substantially similar local code.
COMAR 09.12.54.04 (application): https://regs.maryland.gov/us/md/exec/comar/09.12.54.04. The specific IPMC temperature and heating-season figures were not read on an official state page. Most populous jurisdictions have their own housing codes with set temperatures.
Air conditioningNo statewide requirement to provide air conditioning. Under the rent-escrow statute, there is a rebuttable presumption that the absence of air conditioning is not a covered serious defect, unless it poses a serious and substantial threat to life, health or safety.
Some counties have local air-conditioning requirements for rentals. These were not verified here. Separately, evictions are stayed during excessive-heat warnings (Real Prop. § 8-401(f)).

Privacy, Guests & Animals in Maryland

Cameras & privacyNo landlord-specific statute, but strong criminal rules apply. A person may not place a camera on real property where a private residence is located to deliberately and secretly observe someone inside the residence. It is not a defense that the defendant owns the residence. Exceptions include cameras placed with an adult resident's consent and cameras without intent to secretly observe people inside. Violations are a misdemeanor (up to 1 year and/or $2,500) and give the person observed a civil claim for damages and attorney fees. Secret surveillance with prurient intent in a private place such as a bedroom or bathroom is separately a crime. Recording private conversations generally requires the consent of ALL parties.
§ 3-902: https://mgaleg.maryland.gov/mgawebsite/Laws/StatuteText?article=gcr&section=3-902&enactments=false. § 10-402: https://mgaleg.maryland.gov/mgawebsite/Laws/StatuteText?article=gcj&section=10-402&enactments=false. § 3-903(b)(8) exempts certain licensed security professionals observing common areas of multiunit dwellings.
Guests & occupantsNo statute — the lease governs guests, occupancy limits and roommates. Maryland's landlord-tenant title doesn't define guest versus tenant or give roommate rights. Fair housing law bars discrimination based on familial status and marital status.
Occupancy limits come from local housing codes or the state Minimum Livability Code (COMAR 09.12.54).
Service & support animals (state law)A person with a disability (or a parent of a minor child with a disability) who has or wants a service animal is entitled to full and equal access to housing, and cannot be charged extra for the service animal. The tenant may be liable for damage the animal causes. State law defines 'service animal' as an animal individually trained to do work or tasks for a person with a disability. State fair housing law also bans disability discrimination in rentals. No state statute sets documentation rules for emotional support animals or penalizes misrepresenting an animal.
§ 7-701: https://mgaleg.maryland.gov/mgawebsite/Laws/StatuteText?article=ghu&section=7-701&enactments=false. The § 7-704(c) housing access rule doesn't apply where occupants rent out no more than one room in a single-family home. Emotional support animals are covered through federal Fair Housing Act reasonable-accommodation rules.

How eviction works in Maryland

Eviction cases are heard in: District Court of Maryland (in the county where the property is located); appeals to the circuit court.

  1. Notice: for unpaid rent, written 10-day notice of intent to file (form DC-CV-115) (§ 8-401(c)); for breach of lease, 30 days' written notice (14 days for clear and imminent danger) (§ 8-402.1); for holdover, written notice to quit per § 8-402(c) (60 days for month-to-month).
  2. Landlord files a sworn complaint in District Court (failure to pay rent: form DC-CV-082) stating rent and late fees due (§ 8-401(b)).
  3. Summons issued; sheriff/constable mails notice and serves or posts it. In failure-to-pay-rent cases the trial is set for the fifth day after filing (§ 8-401(b)(4)). A money judgment against a residential tenant requires personal service.
  4. Trial: court may adjourn up to 1 day (longer only by consent). Tenant may pay all rent, late fees, and costs at trial to end the case (§ 8-401(e)).
  5. Judgment for possession: in rent cases, possession must be surrendered within 4 days after trial (extendable by physician's certificate up to 15 days); if not within 7 days, landlord may petition for a warrant of restitution (form DC-CV-081) (§ 8-401(e)-(f)). The Judiciary's housing page describes the wait as 7 business days.
  6. Landlord must order the warrant within 60 days of judgment (or end of any stay) or the judgment is stricken; warrant expires if not acted on within 60 days (§ 8-401(f)).
  7. Landlord must give the tenant written notice at least 6 days before the scheduled eviction (local jurisdictions may set 4 to 14 days) (§ 8-407(b), (e)).
  8. Removal by the sheriff or constable. Evictions are stayed day-to-day for extreme weather (32°F or below, winter storm/blizzard, hurricane/tropical storm, or excessive heat warnings) (§ 8-401(f)). No evictions on Sundays or holidays (Md. Judiciary).

No written answer required in rent cases; failure-to-pay-rent trial is scheduled for the fifth day after the complaint is filed (§ 8-401(b)(4)). Appeal: within 4 days of judgment in rent cases (§ 8-401(i)) — Judiciary materials describe this as 4 business days — and within 10 days in breach-of-lease cases (§ 8-402.1(b)(2)). Right of redemption: tenant may stop a rent eviction by paying all amounts due plus court costs before the eviction is executed, unless the tenant had 3 possession judgments for unpaid rent in the prior 12 months (4 in Baltimore City, per the Judiciary) (§ 8-401(h)).

Maryland landlord-tenant FAQ

How much can a landlord charge for a security deposit in Maryland?
1 month's rent per dwelling unit, regardless of the number of tenants. Up to 2 months' rent is allowed only if the tenant qualifies for Department of Human Services utility assistance, the lease requires the tenant to pay utilities directly to the landlord, and both agree in writing. A landlord who charges more than the cap can be sued for up to 3 times the extra amount plus reasonable attorney's fees. (Md. Code, Real Prop. § 8-203(b)(1)-(3))
How long does a landlord have to return a security deposit in Maryland?
Within 45 days after the tenancy ends, the landlord must return the deposit plus accrued interest, less damages rightfully withheld. (Md. Code, Real Prop. § 8-203(e)(1))
Does a landlord have to pay interest on a security deposit in Maryland?
Required. Simple interest accrues monthly from the date the deposit is paid. The rate is the greater of the 1-year U.S. Treasury yield-curve rate as of the first business day of each year, or 1.5% per year. No interest is owed unless the landlord held the deposit at least 6 months, none accrues for partial months, and it applies only to deposits of $50 or more. (Md. Code, Real Prop. § 8-203(e)(1)-(3))
Does a landlord in Maryland have to give an itemized list of deposit deductions?
Within 45 days after the tenancy ends, the landlord must send a written list of damages claimed plus an itemized statement of the cost of each (with supporting documentation; cost estimates allowed) by first-class mail to the tenant's last known address. If the landlord does not, it forfeits the right to withhold any of the deposit for damages. Where estimates were used, the landlord must notify the tenant when repairs are done and refund any excess within 30 days. (Md. Code, Real Prop. § 8-203(g), (j), (k))
What happens if a landlord in Maryland wrongfully keeps a security deposit?
If the landlord fails to return the deposit and interest within 45 days without a reasonable basis, the tenant may sue for up to 3 times the withheld amount plus reasonable attorney's fees. (Md. Code, Real Prop. § 8-203(e)(4))
How much notice does a landlord have to give before evicting for unpaid rent in Maryland?
Before filing a failure-to-pay-rent case, the landlord must give the tenant written notice of intent to file (Maryland Judiciary form DC-CV-115) giving the tenant 10 days to pay. Notice may be sent by first-class mail with certificate of mailing, affixed to the door, or (if the tenant elected it) by email, text, or tenant portal with proof of transmission. The complaint must state the date notice was given. (Md. Code, Real Prop. § 8-401(c))
How much notice is required to evict for a lease violation in Maryland?
30 days' written notice that the tenant is in violation of the lease and that the landlord wants to repossess; 14 days' written notice if the breach involves behavior showing a clear and imminent danger of serious harm. The court may evict only if it finds the breach was substantial and warrants eviction. (Md. Code, Real Prop. § 8-402.1(a)(1), (b)(1))
How much notice is needed to end a month-to-month lease in Maryland?
Landlord: written notice at least 60 days before expiration for month-to-month tenancies and leases for a stated term over 1 week; 90 days for year-to-year; 7 days for week-to-week with a written lease (21 days without one). Tenant: at least 30 days' notice (90 days for year-to-year). (Md. Code, Real Prop. § 8-402(c)(2)-(3))
Can a landlord enter without notice in Maryland?
Written notice at least 24 hours in advance stating the approximate date/time and specific purpose; entry only 7:00 a.m.-7:00 p.m., Monday-Saturday, unless the tenant agrees in writing to another time or shorter notice. Permitted purposes include repairs/maintenance, inspections, showing the unit, safety, government-ordered work, and responding to a written tenant request. No notice needed in an emergency. (Md. Code, Real Prop. § 8-221)
Is there a limit on late fees in Maryland?
Capped at 5% of the amount of unpaid rent for the rental period. For weekly rent: no more than $3 per week, with a total of no more than $12 per month. No statutory grace period. (Md. Code, Real Prop. § 8-208(d)(3))
Can a tenant repair and deduct from rent in Maryland?
No statute (Md. Code, Real Prop. § 8-211 (rent escrow is the statutory repair remedy))
Can a tenant withhold rent for repairs in Maryland?
Rent escrow. If the landlord fails to fix serious conditions (lack of heat, light, electricity, hot or cold water; inadequate sewage; rodent infestation in 2+ units; dangerous structural defects; fire or health hazards) within a reasonable time after notice, the tenant may file a rent escrow action and pay rent into court, or withhold rent and raise the conditions as a defense to an eviction. Notice can be certified-mail written notice, actual notice, or a government violation notice. More than 30 days after notice is presumed unreasonable. (Md. Code, Real Prop. § 8-211(d), (f), (g), (h), (k), (m))
Can a landlord retaliate against a tenant for complaining in Maryland?
Landlord may not bring or threaten a possession action, arbitrarily raise rent or reduce services, or terminate a periodic tenancy because the tenant made a good-faith complaint (to the landlord or a public agency) about a lease/law violation or a substantial health or safety threat, sued or testified in a suit involving the landlord, joined a tenants' organization, or called police/emergency services. Remedy: damages up to 3 months' rent plus reasonable attorney's fees and costs. (Md. Code, Real Prop. § 8-208.1)
Is there rent control or a limit on rent increases in Maryland?
No statewide rent control or statewide cap on rent increases. Local jurisdictions may adopt rent regulation (statewide preemption not found). (Md. Office of the Attorney General, 'Landlords and Tenants: Tips on Avoiding Disputes' (Rev. Feb. 2025); DHCD Tenants' Bill of Rights (eff. Oct 1, 2026))
Can a landlord change the locks or shut off utilities in Maryland?
Prohibited. A landlord may not take or threaten to take possession by locking out the tenant, willfully cutting heat, running water, hot water, electricity, or gas to force the tenant out, or by any other action. Possession may be taken only under a court warrant of restitution executed by a sheriff or constable, or after abandonment/surrender. Remedy: actual damages plus reasonable attorney's fees and costs; other remedies also available. (Md. Code, Real Prop. § 8-216)
What is the small claims court limit in Maryland for a deposit dispute?
$5,000 (exclusive of interest, costs, and attorney's fees), District Court of Maryland (Md. Code, Cts. & Jud. Proc. § 4-405)
How do you remove a squatter in Maryland?
Wrongful detainer action in District Court against anyone who holds real property without a right to possession, where no landlord-tenant (Title 8) remedy applies. The court must summon the occupant at once, and the hearing must be held no more than 10 business days after the complaint is filed. If the occupant cannot be found after two good-faith attempts on different days, the process server files an affidavit, sends the complaint by certified and first-class mail, and posts the summons on the property. Service must be completed within 4 business days of filing. No counterclaims are allowed. If the owner wins, the court orders restitution and issues a warrant to the sheriff or constable. Damages, costs and attorney fees are available if claimed and the occupant was personally served. Either side may appeal within 10 days. (Md. Code, Real Prop. § 14-132)
What can a landlord do with a tenant's abandoned property in Maryland?
No statewide storage-and-sale procedure. At eviction, the warrant of restitution directs the sheriff or constable to remove the tenant's belongings. At least 6 days before the scheduled eviction, the landlord must send written notice by first-class mail with certificate of mailing, post it on the front door (with a date-stamped photo), and text or email it if the landlord has that contact information. The notice must include a statutory warning that the tenant could lose all belongings left inside and that local disposal laws vary. A lease may not let the landlord take the tenant's property unless the tenancy has ended and the property was abandoned. Disposal is governed by local law. (Md. Code, Real Prop. §§ 8-401(f)(1)(i), 8-407(b), 8-208(d)(6))
Is there a limit on rental application fees in Maryland?
There is no dollar cap. If any non-deposit fee charged to an applicant exceeds $25, the landlord must return it within 15 days after move-in or after either party says in writing that no tenancy will occur. The landlord may keep only the amount actually spent on a credit check or other application expenses. Penalty for not returning it: twice the fee. The application must explain the tenant's liabilities and these rules. Does not apply to landlords offering 4 or fewer units on one parcel or location, or to seasonal or condominium rentals. (Md. Code, Real Prop. § 8-213)
What rental fees are banned or limited in Maryland?
Move-in cap: a lease may not require more than the security deposit plus the first month's rent to start the lease and move in. Late fees are capped at 5% of the unpaid rent (weekly leases: $3 a week, $12 a month). A lease may not make the tenant pay the District Court filing surcharge assessed against the landlord, except as § 7-301(c)(5)(ii) of the Courts Article allows. The landlord may charge no more than $5 for the 6-day eviction notice. The lease must include the Maryland Tenants' Bill of Rights. (Md. Code, Real Prop. §§ 8-208(c)(4), 8-208(d)(3), (11), (13); 8-407(b)(3))
Can a domestic violence survivor break a lease in Maryland?
A tenant who is, or whose legal occupant is, a 'victim of abuse' may end future lease liability with written notice of intent to vacate, sent by first-class mail or hand delivery, stating the victim status. The notice must include one of these: a protective order, a peace order based on abuse, or a qualified third party's report signed within the past 60 days with the alleged abuser's name and description redacted. The tenant has 30 days to move out and owes rent only from the notice date until move-out, up to 30 days. A tenant who leaves sooner must send a signed, notarized notice of vacating by first-class mail or hand delivery; the landlord must then inspect and confirm the rent owed or refund due. If the tenant has not left within 30 days, the landlord may treat them as a holdover or treat the notice as withdrawn. The abuser's liability does not end. (Md. Code, Real Prop. §§ 8-5A-02, 8-5A-03)
When can a tenant break a lease without penalty in Maryland?
Military: an active service member, or the member's spouse, who receives a change of assignment owes no more than rent then due plus 30 days' rent after giving written notice and proof, plus repair costs for damage. A change of assignment includes PCS orders, temporary duty over 90 days, orders to move on base, and release from active duty. Medical: a tenant owes no more than 2 months' rent after moving out if, before vacating, they give written notice with a move-out date and a certification from a Maryland-licensed physician or psychologist, on letterhead or a prescription form. The certification must state that a medical condition restricts mobility, requires a move for a higher level of care, or is a mental disorder making continued residence unfeasible. The medical rule does not apply if the lease already has an early-termination clause requiring 1 month's notice or less and charging 2 months' rent or less. (Md. Code, Real Prop. §§ 8-212.1, 8-212.2)
Can an eviction record be sealed or removed in Maryland?
Yes (shielding). Failure-to-pay-rent cases that do not end in a judgment for possession are shielded automatically by the District Court within 60 days after final resolution. If there was a judgment for possession, the tenant may ask the court to shield the records. The court may do so if the tenant redeemed (paid in full) and at least 12 months have passed, or for good cause. Shielded records may be opened only at the tenant's written request or by court order for good cause. Separately, § 8-502 allows petitions to shield COVID-era nonpayment cases filed Mar. 5, 2020 to Dec. 31, 2021. (Md. Code, Real Prop. §§ 8-503, 8-502 (SB 19 / HB 181 of 2024))
Can a landlord refuse Section 8 vouchers in Maryland?
Yes (HOME Act). It is illegal to refuse to rent to someone, or discriminate in rental terms, because of source of income. 'Source of income' means any lawful source of money paid to or for a renter, including any government or private rental assistance and Housing Choice (Section 8) vouchers. (Md. Code, State Gov't §§ 20-705, 20-701(j))
Do tenants have a right to a free lawyer in eviction cases in Maryland?
Yes, a statewide access-to-counsel program. 'Covered individuals' have access to legal representation in eviction matters through the Access to Counsel in Evictions Program, run by the Maryland Legal Services Corporation. A covered individual is a non-owner occupant, including a public-housing tenant, whose household income is no more than 50% of the state median income, adjusted for household size. (Md. Code, Real Prop. §§ 8-901 to 8-903 (Access to Counsel in Evictions, 2021))
What does a Maryland notice to pay rent or quit have to include?
Before filing for failure to pay rent, the landlord must give written notice of intent to file in District Court if the tenant does not cure within 10 days. The notice must be on the form created by the Maryland Judiciary. It is delivered by first-class mail with certificate of mailing, by posting on the door of the premises, or, if the tenant has elected it, by email, text or electronic tenant portal with proof of transmission. The complaint must state the date the notice was given, and the tenant may challenge that date. (Md. Code, Real Prop. § 8-401(c))
What does a Maryland notice to end a month-to-month tenancy have to include?
Written notice of intent to end the tenancy: 60 days before the end of a month-to-month tenancy or a written lease longer than 1 week. Year-to-year tenancies need 90 days. Week-to-week tenancies need 7 days with a written lease, 21 days without one. Shorter periods (30 days for month-to-month) apply in the foreclosure situation in § 8-402(c)(4), which does not apply in Baltimore City, Montgomery County, or to landlords with 5 or more units. A lease may not shorten the legal notice period. Accepting payment after the notice does not waive it unless agreed in writing. (Md. Code, Real Prop. §§ 8-402(c)(1)-(5), 8-208(d)(5))
What must a Maryland security deposit itemization include?
If any part of the deposit is kept, the landlord must send by first-class mail to the tenant's last known address, within 45 days after the tenancy ends, a written list of damages claimed together with an itemized statement of the cost incurred. A landlord who does not do so loses the right to keep any of the deposit for damages. A tenant who was evicted, or who abandoned the unit before the tenancy ended, must first demand the deposit by first-class mail within 45 days. The landlord then has 45 days to mail the list and return the balance with interest. (Md. Code, Real Prop. § 8-203(g), (h))
How long does a landlord have to sue for unpaid rent in Maryland?
3 years for a civil action at law, including suits for unpaid rent or damages under a written or oral lease. 12 years if the lease is a contract under seal (a 'specialty'). (Md. Code, Cts. & Jud. Proc. § 5-101; § 5-102(a)(5))
Can a landlord accept rent during an eviction in Maryland?
In tenant-holding-over cases, accepting any payment after notice but before eviction does NOT waive the notice to quit, notice of intent to vacate, or judgment for possession, unless the parties specifically agree otherwise in writing. Accepted payments go first to rent through the date the landlord recovers possession, then costs and damages; any excess is returned like a security deposit. In nonpayment cases, the tenant can redeem ('pay and stay') by paying all past-due amounts set by the court plus costs and fees any time before the eviction is actually carried out. This right is lost after 3 rent judgments in the prior 12 months. (Md. Code, Real Prop. § 8-402(c)(5); § 8-401(h))
Can you be evicted in the winter in Maryland?
Yes, statewide. The district administrative judge must stay execution of a residential eviction warrant, day to day, during extreme weather. This includes a temperature or next-day forecast of 32°F or lower, a winter storm or blizzard warning, a hurricane or tropical storm warning, or an excessive heat warning. The eviction must then be completed within 5 days after conditions end. (Md. Code, Real Prop. § 8-401(f)(2))
Can a landlord give notice by text or email in Maryland?
The 10-day notice of intent to file a nonpayment case must use the Judiciary's form and be delivered by first-class mail with a certificate of mailing, affixed to the door, or, if the tenant elected it, by email, text or tenant portal with proof of transmission. Rent-increase notices go by first-class mail with a certificate of mailing or, if the tenant elects, electronically; a lease can't require electronic notice of rent increases. If the landlord hasn't listed its name and address (in the lease or a posted sign), tenants may send notices to whoever receives rent, where rent is paid, or the tax-bill address. (Md. Code, Real Prop. § 8-401(c)(1)-(2); § 8-209(b)(2); § 8-208(d)(9); § 8-210(a))
How much notice is required for a rent increase in Maryland?
Written notice is required before any residential rent increase: at least 90 days for terms longer than 1 month, 60 days for terms over 1 week up to 1 month, and 7 days (written lease) or 21 days (no written lease) for week-to-week or shorter. Delivery is by first-class mail with certificate of mailing, or electronically if the tenant elects. Landlords cannot make electronic delivery a condition of approving an application. Local laws may add protections. (Md. Code, Real Prop. § 8-209(b)-(c))
Does a landlord have to give a copy of the lease in Maryland?
Landlords offering 5 or more units must use a written lease. Every lease must include a habitability statement, each party's duties for heat, gas, electricity, water and repairs, a security-deposit receipt, and a copy of the current Maryland Tenants' Bill of Rights (DHCD). On written request, the landlord must give a prospective applicant a copy of the proposed lease form without requiring signing or a deposit. The landlord's name, address and phone, and the agent for notices and service, must be in the lease or posted on the property. (Md. Code, Real Prop. § 8-208(a)-(c); § 8-210(a))
What are tenants' rights in a foreclosure in Maryland?
Maryland adopts PTFA-style protections. A foreclosure buyer takes the property subject to bona fide tenants' rights and must give a 90-day notice to vacate, sent by first-class AND certified mail, return receipt requested, stating its date, the effective date and the basis. A bona fide lease generally continues to its end, unless the buyer will live there as a primary residence (then 90 days). Longer state or local protections still apply. A landlord who has received a notice of intent to foreclose may end month-to-month tenancies with 30 days' notice (60 days for year-to-year). (Md. Code, Real Prop. § 7-105.8(a)-(b); § 8-402(c)(4)(ii))
Does a landlord have to fix mold in Maryland?
Yes, by statute (Maryland Tenant Mold Protection Act, effective July 1, 2025). Landlords must give each tenant the state mold information pamphlet when the lease is signed and on request, and ask the tenant to sign an acknowledgment. Within 15 days after written notice of mold from the tenant, a building occupant or the local housing-code agency, the landlord must do a mold assessment. If mold is found, the landlord must remediate it within 45 days after the assessment, or within a reasonable time if 45 days isn't feasible. Assessment and remediation must follow industry guidelines and state and local law. The landlord must keep the property properly ventilated with low indoor humidity, communicate with occupants during the work, and meet minimum livability codes. (Md. Code, Real Prop. § 8-220; Md. Code, Envir. § 6-1702 (2025 Md. Laws ch. 539, SB 856))
Who pays for pest control and bed bugs in Maryland?
No bed-bug-specific statute. A rodent infestation in two or more units is a listed serious defect: if the landlord fails to fix it within a reasonable time after notice (over 30 days is presumed unreasonable), the tenant may use rent escrow. Other infestations that create a health hazard can also qualify. The state Minimum Livability Code, which adopts the International Property Maintenance Code, applies where no substantially similar local code exists. (Md. Code, Real Prop. § 8-211(d)(3), (d)(5), (g); COMAR 09.12.54.03-.04)
Does a landlord have to provide heat in Maryland?
Lack of heat is a listed serious defect: if the landlord doesn't fix it within a reasonable time after notice, the tenant can use rent escrow. This does not apply when the tenant pays the utility and the lack of heat is from the tenant's own nonpayment. No state statute sets a minimum temperature. The state Minimum Livability Code adopts the 2012 International Property Maintenance Code, which contains heating standards, for housing in localities without a substantially similar local code. (Md. Code, Real Prop. § 8-211(d)(1); COMAR 09.12.54.03-.04)
Does a landlord have to provide air conditioning in Maryland?
No statewide requirement to provide air conditioning. Under the rent-escrow statute, there is a rebuttable presumption that the absence of air conditioning is not a covered serious defect, unless it poses a serious and substantial threat to life, health or safety. (Md. Code, Real Prop. § 8-211(e)(2)(iv))
What can a landlord deduct from a deposit for cleaning or damage in Maryland?
Deposits may be withheld for unpaid rent, for damage from breach of the lease, or for damage by the tenant, family, agents, employees, guests or invitees beyond 'ordinary wear and tear' to the premises, common areas, major appliances and landlord-owned furnishings. The statute doesn't define ordinary wear and tear or specifically address cleaning, painting or carpet. Deductions must be itemized with actual costs. (Md. Code, Real Prop. § 8-203)
Can a landlord put cameras in or around a rental in Maryland?
No landlord-specific statute, but strong criminal rules apply. A person may not place a camera on real property where a private residence is located to deliberately and secretly observe someone inside the residence. It is not a defense that the defendant owns the residence. Exceptions include cameras placed with an adult resident's consent and cameras without intent to secretly observe people inside. Violations are a misdemeanor (up to 1 year and/or $2,500) and give the person observed a civil claim for damages and attorney fees. Secret surveillance with prurient intent in a private place such as a bedroom or bathroom is separately a crime. Recording private conversations generally requires the consent of ALL parties. (Md. Code, Crim. Law § 3-903; § 3-902; Cts. & Jud. Proc. § 10-402(c)(3))
Can a landlord limit guests or roommates in Maryland?
No statute — the lease governs guests, occupancy limits and roommates. Maryland's landlord-tenant title doesn't define guest versus tenant or give roommate rights. Fair housing law bars discrimination based on familial status and marital status. (Md. Code, Real Prop. Title 8, Subtitles 1-4 (checked); State Gov't § 20-705)
Can a landlord deny a service or emotional support animal in Maryland?
A person with a disability (or a parent of a minor child with a disability) who has or wants a service animal is entitled to full and equal access to housing, and cannot be charged extra for the service animal. The tenant may be liable for damage the animal causes. State law defines 'service animal' as an animal individually trained to do work or tasks for a person with a disability. State fair housing law also bans disability discrimination in rentals. No state statute sets documentation rules for emotional support animals or penalizes misrepresenting an animal. (Md. Code, Human Servs. §§ 7-701(g), 7-704(c); State Gov't § 20-705)
