Mold in an Oklahoma rental: what tenants and landlords should know

Oklahoma has no mold-specific rental law, and no state agency takes mold complaints. OSDH says it has no authority over them (OSDH), and the Oklahoma City-County Health Department says no Oklahoma government agency is responsible for mold complaints (OCCHD). What does apply is the Oklahoma Residential Landlord and Tenant Act, which covers the leaks, plumbing and HVAC problems that cause mold. This page is plain information, not legal advice. For a real dispute, talk to a lawyer or a legal aid office.

What the landlord has to do

Under 41 O.S. §118, a landlord must make all repairs and do whatever is necessary to keep the dwelling unit and premises in a fit and habitable condition. The landlord must also keep electrical, plumbing, sanitary, heating, ventilating and air-conditioning facilities that they supply in good and safe working order (41 O.S. §118). A roof leak, a dripping supply line, or an AC unit that floods its closet usually falls on the landlord. The law does let a landlord and tenant agree that the tenant will handle specified repairs, but only in a conspicuous writing separate from the lease.

What the tenant can do, step by step

Section 121 sets out the tenant's remedies. It was amended effective November 1, 2022 (HB 3409). In outline:

1. Put it in writing. The tenant's rights under §121 don't arise until written notice has been given to the landlord. A text may not be enough. Keep a dated copy, along with photos of the mold and the water source.
2. Fourteen days to fix. If the problem is a material noncompliance that affects health or safety, the tenant's notice can say the lease will end on a date at least 30 days after the landlord receives it, unless the breach is fixed within 14 days.
3. Repair and deduct. If the repair would cost no more than one month's rent, the tenant can give written notice of their intent to fix it at the landlord's expense. If the landlord hasn't acted after 14 days, the tenant can have the work done in a workmanlike manner and deduct the actual, reasonable cost from rent, with an itemized statement. That cap was raised from $100 to one month's rent in 2022.
4. Uninhabitable or an imminent threat. If the problem makes the unit uninhabitable or poses an imminent threat to health and safety, and it isn't fixed as promptly as conditions require, the tenant can end the lease immediately with written notice.

None of these rights apply if the tenant, their family, a guest or a pet caused the condition.

Documenting mold in a rental

• Photos with dates, wide shots and close-ups, plus anything that shows the source: a ceiling stain under a bathroom, a wet carpet edge, a dripping AC line.
• A simple hygrometer reading if the whole unit feels damp. EPA's target is below 60 percent relative humidity.
• A written account from someone who looked at it. A lab test isn't required to show there's a problem. EPA says sampling is usually unnecessary when growth is visible (EPA). See mold inspection and testing.

For landlords

Mold calls in rentals are mostly water calls. A fast response is cheaper than letting a leak become a wall replacement or a vacancy. Fix the source, have the damaged material removed properly (see what remediation should include), and keep the paperwork. If the unit took water in a storm, our flood page covers the first 48 hours.

Inside Oklahoma City limits

OCCHD investigates single and multi-unit housing problems that create a public health hazard, and visible sewage inside a dwelling, within Oklahoma City limits and Oklahoma County. Mold on its own isn't something it says it handles (OCCHD).

Questions people ask

Does my Oklahoma landlord have to fix mold?

Oklahoma has no mold-specific statute, but 41 O.S. §118 requires landlords to keep the unit fit and habitable and to maintain plumbing and HVAC they supply. The leak or equipment failure that causes mold usually falls under that duty.

Can I withhold rent for mold in Oklahoma?

The act doesn't provide for simply withholding rent. It provides written notice, a 14-day cure period, repair-and-deduct up to one month's rent, and lease termination in some cases. Talk to a lawyer or legal aid before stopping payment.

Who do I call about mold in an OKC apartment?

OSDH and OCCHD both say no state agency handles mold complaints. Start with written notice to the landlord under the landlord-tenant act. OCCHD takes complaints about housing conditions that cause a public health hazard and about sewage inside a dwelling.
