The rules in Hawaii
| Mold | No statute — Hawaii's Residential Landlord-Tenant Code has no mold-specific disclosure or remediation rule. Mold is addressed under the landlord's general duties to comply with building and housing laws materially affecting health and safety and to make all repairs needed to keep the premises habitable. Tenants must keep their unit as clean and safe as conditions permit (§ 521-51(2)); mold caused by the tenant's conduct may be the tenant's responsibility. Source: HRS § 521-42(a)(1), (3) |

| Pests & bed bugs | No statute — Hawaii law does not specifically assign pest or bed-bug treatment and has no bed-bug disclosure rule. Infestations are handled under the landlord's habitability and code-compliance duties and the tenant's duty to keep the unit clean and dispose of garbage properly. Except for single-family residences, the landlord must provide garbage receptacles and arrange frequent removal (§ 521-42(a)(5)). Lease terms commonly allocate termite and pest treatment. |
| Heat | No statute — Hawaii law does not require landlords to provide heat or set minimum indoor temperatures. Heating equipment the landlord supplies must be kept in good working order as one of the 'facilities and appliances supplied by the landlord.' Hot water is not separately required by § 521-42; the landlord must supply running water as reasonably required (except single-family residences). County housing codes may add requirements. Source: HRS § 521-42(a)(4) |
| Air conditioning | No statute — landlords are not required to provide air conditioning, and there is no maximum indoor temperature. If the landlord supplies A/C or fans, they must be maintained in good working order, subject to reasonable wear and tear. Whether A/C is included is a lease matter; check the move-in inventory required by § 521-42(a). Source: HRS § 521-42(a)(4) |

| California | Visible mold growth, as determined by a health officer or code enforcement officer, and dampness of habitable rooms are listed as substandard housing conditions, which make a unit untenantable under the landlord's repair duty. Minor mold on surfaces that can collect moisture during normal use is excluded. The Toxic Mold Protection Act also requires landlords to give written mold disclosures and a state mold booklet to tenants, but those duties do not start until the Department of Public Health adopts mold exposure standards, guidelines and the booklet. Cal. Health & Safety Code § 17920.3(a)(11), (a)(13); Cal. Civ. Code § 1941.1(a); Health & Safety Code §§ 26147, 26148 | The landlord must keep the building, grounds and all areas it controls clean and free of rodents and vermin, and insect, vermin or rodent infestation is a substandard condition. Under the bed-bug law, the landlord may not show or rent a vacant unit it knows has a current bed-bug infestation, must give every new tenant a written bed-bug information notice (all existing tenants since January 1, 2018), and must notify tenants in writing within two business days of a pest control operator's findings for inspected units (and all tenants for confirmed common-area infestations). Tenants must cooperate with inspections. Cal. Civ. Code §§ 1941.1(a)(6), 1954.602, 1954.603, 1954.604, 1954.605; Health & Safety Code § 17920.3(a)(12) | Yes. A unit is untenantable if it substantially lacks heating facilities that met code when installed and are kept in good working order, and lack of adequate heating is a substandard condition. State housing regulations (Title 25) require dwelling units to be able to maintain a minimum indoor temperature. Cal. Civ. Code § 1941.1(a)(4); Health & Safety Code § 17920.3(a)(6); Cal. Code Regs., tit. 25, § 34 |
