Can I Sue My Landlord in Delaware?
Yes — in many situations. These are the main claims Delaware tenants bring, what the law lets you recover, and where to file. Each rule links to the statute or official source. Most claims under the small claims limit can be filed without a lawyer.
Before you sue
- Write down what happened, with dates, and keep photos, texts, emails and receipts.
- Send your landlord a written demand (templates below) and give a reasonable deadline.
- Check the deadline to sue and the court's dollar limit (below).
- If the amount is over the small claims limit, or you are facing eviction, talk to a lawyer or legal aid first.
Your security deposit wasn't returned
| Penalty for withholding | Double the amount wrongfully withheld if not returned within 20 days. Failure to disclose the escrow account location within 20 days of written request, or using a non-compliant bank, forfeits the deposit to the tenant (double if not then returned within 20 days).

|---|---|
| Deposit return deadline | 20 days after the lease expires or terminates. Tenant must give a written forwarding address at or before termination; without it the landlord is excused from notice and double damages but still owes the unused deposit, and tenant must claim it in writing within 1 year (§ 5514(h)).

You were locked out or your utilities were cut off
| Lockouts & utility shutoffs | Without a valid court order, a landlord may not oust or exclude the tenant. Tenant may recover possession or terminate, and recover the greater of treble damages or 3 times per diem rent for the exclusion period, plus costs (not attorney fees). Landlord may not shut off utility service for nonpayment of rent or utility charges or for any other breach. Re-verified 2026-10-27. Source: 25 Del. C. §§ 5313, 5312(e) |

Your landlord retaliated after you complained
| Landlord retaliation | Landlord may not seek possession, force the tenant out, raise rent, or cut services after the tenant in good faith complains of a code violation, a government agency cites a violation, the tenant organizes or leads a tenant organization, or the tenant pursues a legal remedy. Rebuttable presumption if the adverse action is within 90 days. Tenant recovers the greater of 3 months' rent or treble damages, plus costs (not attorney fees). § 5516(d) lists 12 defenses (e.g., good-faith owner occupancy, demolition). Re-verified 2026-10-27.

Your landlord won't make repairs
| Repair and deduct | If the landlord fails to make required repairs within 30 days of written notice (or fails to begin corrective steps within 10 days), tenant may have the work done and deduct up to the lesser of $400 or one-half of one month's rent, with receipts. Re-verified 2026-10-27. Source: 25 Del. C. § 5307 |
|---|---|
| Withholding rent | Only for essential services: if hot water, heat, water, or electricity (that the landlord must supply) is substantially unavailable for 48 hours or more after notice, tenant may withhold two-thirds of the per diem rent for the period, or terminate, or obtain substitute housing (landlord liable for added cost up to one-half of the abated rent). For substantial deprivation, tenant may terminate if not fixed within 15 days of written notice (§ 5306). Re-verified 2026-10-27. Source: 25 Del. C. § 5308 |
| Mold | No statute — general habitability/repair duty applies. Delaware has no mold disclosure or remediation law for rentals. The landlord must comply with all state and local housing codes, provide a unit that does not endanger the health, welfare or safety of tenants, and make all repairs needed to keep the unit in the condition it was, or should have been, at the start of the tenancy. If the landlord materially fails to comply with codes affecting the premises, the tenant may use the remedies in §§ 5306-5307, including termination or repair and deduction from rent after written notice. A 2025 act (85 Del. Laws c. 98) added a lead-safe requirement to § 5305 with phased implementation. Re-verified 2026-10-27. Source: 25 Del. C. § 5305(a)(1)-(2), (4) |
| Pests & bed bugs | Delaware has a bed-bug statute. Before renting, the landlord must visually inspect the unit for evidence of bed bugs and disclose if adjacent units are infested or being treated. After a report of a known or suspected infestation, the landlord must inspect or get a pest management professional to inspect within 120 hours, start professional remediation within 14 days of notice if bed bugs are found, inspect adjacent units within 5 days, notify affected tenants of the findings, and keep written records. The landlord pays for investigation and remediation if the tenant reports within 60 days of move-in or within 30 days of an infestation being found in an adjoining unit; for later reports the tenant shares reasonable remediation costs for the tenant's unit (except in public housing authority properties). Tenants may not knowingly bring in infested belongings. Added by 83 Del. Laws c. 451. Entry for bed-bug inspection or treatment requires the notice in § 5509. Other pests fall under the general habitability duty in § 5305. Re-verified 2026-10-27. Source: 25 Del. C. § 5317 |
| Heat | Only if the rental agreement says so: the landlord must supply (or arrange) water, hot water, heat and electricity when the lease so specifies. If the landlord substantially fails to provide heat, the tenant may, on written notice, procure substitute housing with rent abating, or keep two-thirds of the per-diem rent while heat is not supplied, among other remedies. State law sets no minimum indoor temperature. Re-verified 2026-10-27. Source: 25 Del. C. §§ 5305(b)(2), 5308 |

Your landlord entered without notice or invaded your privacy
| Landlord entry notice | At least 48 hours' notice, entry only between 8:00 a.m. and 9:00 p.m., except for tenant-requested repairs. Emergency entry allowed at any time. Tenant may waive the 48-hour notice only for showings to prospective tenants or buyers, in a signed addendum. Landlord may not abuse access or use it to harass. Re-verified 2026-10-27. Source: 25 Del. C. § 5509 |
|---|---|
| Cameras & privacy | No landlord-specific statute, but Delaware's privacy law applies directly: it is a crime to install, in any private place, a device for observing, photographing or recording sounds or events without the consent of the persons entitled to privacy there, or to use a device outside a private place to pick up sounds from inside that would not ordinarily be audible. Recording people undressing where they expect privacy, and intercepting private communications without consent, are also crimes. A tenant is the person entitled to privacy in the rented unit, so a landlord may not install recording devices inside it without the tenant's consent. The landlord must give at least 48 hours' notice before entering (except tenant-requested repairs), may enter only 8:00 a.m. to 9:00 p.m., and may not use access to harass (§ 5509(b)). Re-verified 2026-10-27. |
You were refused or treated differently because of Section 8 or other income
| Statewide ban on refusing Section 8 / source of income | Yes. Statewide ban on refusing to rent, or renting on different terms, because of source of income, defined to include any lawful income and rental payments from any government or private assistance program (covers housing vouchers). Landlords may still apply income-sufficiency and credit criteria in a commercially reasonable way without regard to source. A landlord may deny an application if a public housing authority fails to follow the standardized voucher tenancy-approval sequence. § 5116 (Title 25) at https://delcode.delaware.gov/title25/c051/sc01/index.html. Owner-occupied buildings of 4 or fewer units are largely exempt from § 4603 (§ 4607(e)); § 4607 has versions effective until and after Dec. 31, 2028. Re-verified 2026-10-27. |

Other claims tenants bring in Delaware
| Constructive eviction (conditions forced you out) | No Delaware statute uses the term "constructive eviction," but the Landlord-Tenant Code gives similar move-out rights. If a condition deprives the tenant of a substantial part of the benefit or enjoyment of the bargain, the tenant may give written notice and end the lease if the landlord does not fix it within 15 days; if the condition makes the home uninhabitable or is an imminent threat to health or safety, the tenant may end the lease immediately after notice, without going to court. If the landlord caused the condition willfully or negligently, the tenant may recover the greater of the extra cost of substitute housing for the rest of the term, or one month's rent plus the security deposit. If heat, hot water, water or electricity is substantially not provided for 48 hours after notice, the tenant may end the lease immediately on written notice. A tenant cannot end the lease for a condition the tenant, a family member or a guest caused by lack of due care. A tenant who ends the lease wrongfully stays bound by it. Re-verified 2026-10-27. Source: 25 Del. C. §§ 5306, 5308(a) |
|---|---|
| Covenant of quiet enjoyment | No Delaware statute in the Landlord-Tenant Code sets out a general covenant of quiet enjoyment. The Code protects the tenant's possession and use instead: a tenant removed or locked out without a valid court order may recover possession or end the lease and recover treble damages or three times the daily rent for the lockout period, whichever is greater, and a tenant may end the lease over a condition that deprives the tenant of a substantial part of the benefit or enjoyment of the bargain. A version of § 5512 taking effect March 8, 2027 refers to a breach of the covenant of quiet enjoyment for certain single-room rentals in a landlord's own home. Re-verified 2026-10-27. Source: 25 Del. C. §§ 5306(a), 5313 |
| Injuries on the property | No Delaware statute sets a general rule on landlord liability for injuries. A lease clause that excuses or limits the landlord's liability arising under the law, or makes the tenant indemnify the landlord, is not allowed. Liability for a particular injury is otherwise decided under court decisions on negligence. Re-verified 2026-10-27. Source: 25 Del. C. § 5301(a)(3) |
Where and when to sue
| Small claims limit | $25,000. The Justice of the Peace Court hears debt, trespass (property damage only), replevin, security deposit and landlord-tenant cases and may not award more than $25,000; a plaintiff may sue for a larger claim by giving up the excess. Trespass claims in this court cannot include personal injury or mental anguish. |
|---|---|
| Small claims filing fee | Debt complaint: $35 (under $1,000), $40 ($1,000 to $5,000), $45 (over $5,000). Service by the court is included in the filing fee; an alias (second service attempt) is $20. A fee waiver is available by notarized application (Civil Form 49). |
| Deadline to sue on a written lease | 3 years. Actions based on a promise, and actions to recover a debt not evidenced by a record or by an instrument under seal, must be brought within 3 years of when the claim accrues. Delaware sets no separate, longer period for ordinary written leases. A written contract involving at least $100,000 may set its own period of up to 20 years. Leases under seal and debts 'evidenced by a record' fall outside the 3-year bar. The § 8108 mutual-running-account rule may delay accrual. Re-verified 2026-10-27. Source: 10 Del. C. § 8106(a), (c) |
