Oregon Habitability Laws: Repair Timelines and Tenant Remedies

Oregon habitability laws require your landlord to keep the rental weatherproof, heated to at least 68°F, supplied with hot and cold running water, safely wired, properly ventilated, and free of rodents and vermin. The core statute is ORS 90.320, and it applies for the entire tenancy, not just move-in day.¹ When a landlord falls short, you have real tools: written notice, repair-and-deduct, rent reductions, and in the most serious cases a 48-hour lease termination.

What a Habitable Rental Must Include

Under ORS 90.320, a unit is considered unhabitable if it substantially lacks any of the following:

Effective waterproofing and weather protection of the roof and exterior walls, including windows and doors.
Plumbing facilities that conform to applicable law and are maintained in good working order.
Hot and cold running water connected to an approved water system and capable of providing safe drinking water.
A heating system capable of maintaining at least 68°F in habitable rooms.
Safe wiring, working outlets, and functional light fixtures.
Adequate ventilation, including operable windows or mechanical exhaust in kitchens and bathrooms.
Clean, safe common areas free from debris, rodents, and vermin.
Floors, walls, ceilings, and stairways in good repair.

Each item is a legal obligation. A landlord who lets any of them slide opens the door to the enforcement remedies described below.¹

You and your landlord can agree in writing that you’ll handle specific maintenance tasks, but the agreement must be in good faith, clearly disclose the terms, and can’t be used to dodge the landlord’s core obligations or reduce services to other tenants in the building.¹

One boundary worth knowing up front: Oregon law does not require landlords to provide air conditioning or cooling. If your lease promises AC, that becomes a contract obligation, but the habitability statute itself only mandates heat.²

Essential Services: Heat, Water, and Electricity

Oregon law singles out certain services for faster, stronger protection. A permanently installed heating system capable of holding at least 68°F in habitable rooms is required; portable space heaters do not count. Running water must come through an approved system with safe drinking water and adequate pressure. Electrical wiring, outlets, and fixtures must be safe and functional, with lighting maintained in common areas like hallways and stairwells. Technical standards for residential electrical work come from the Oregon Residential Specialty Code.³

When one of these services fails because of the landlord’s neglect, you move out of the ordinary 30-day repair timeline and into the essential-services track under ORS 90.365, with remedies that take effect in days rather than weeks.

Smoke Alarms, Carbon Monoxide Alarms, and Lead Paint

Under ORS 90.316, a landlord cannot even begin a new tenancy unless the unit has properly functioning carbon monoxide alarms that comply with State Fire Marshal rules and the state building code. This applies whenever the unit contains a CO source such as a gas furnace, water heater, or attached garage, or is connected by a door or ductwork to a room that does. At the start of a new tenancy, the landlord must supply working batteries for any battery-operated or battery-backup CO alarm.⁴

Smoke alarms are required under Oregon building and fire codes, generally inside every bedroom, outside each sleeping area, and on every level of the dwelling. The landlord is responsible for making sure alarms are present and working when you move in.

If your unit was built before 1978, federal law requires the landlord to disclose known lead-based paint hazards before you sign the lease, share any records or reports they have, include a specific lead warning, and give you the EPA pamphlet “Protect Your Family From Lead in Your Home.”⁵ A knowing failure to disclose carries a federal civil penalty of up to $22,263 per violation.⁶ Renovation work on a pre-1978 unit must be done by certified professionals using EPA lead-safe practices.

Mold, Moisture, and Pests

Oregon has no standalone mold statute. Mold is where three habitability duties converge: weatherproofing, plumbing, and ventilation. When any of those systems fail and mold develops as a result, the landlord has to fix the underlying problem and remediate the mold. The CDC recommends drying wet materials within 48 hours and repairing the source of water entry; painting over moldy surfaces is considered inappropriate remediation.⁷

For pests, ORS 90.320 requires landlords to keep the property free from rodents and vermin. Infestations that make the unit unsanitary are habitability violations, and the landlord is generally responsible for extermination unless your own behavior caused the problem. Bedbugs follow the same rule: landlords must promptly treat infestations and are always responsible for treating common areas. If you find bedbugs, notify your landlord in writing right away. The written record is what triggers the landlord’s duty and protects you from being blamed for any delay.

Enforcing Your Rights: Written Notice and Repair Timelines

Oregon gives tenants a tiered set of tools, and the severity of the problem determines which one you use. Start with written notice to the landlord that describes the specific problem.

Ordinary Violations: 30 Days

Under ORS 90.360, your written notice must state that the rental agreement will terminate on a date at least 30 days out if the landlord doesn’t fix the issue. If the landlord repairs the problem within that window, the tenancy continues. If the same problem returns within six months after the supposed fix, you can terminate with just 14 days’ written notice.⁸

Essential Services: 7 Days, or 48 Hours in a Crisis

When a landlord fails to supply heat, running water, electricity, or another essential service, the landlord has only seven days to remedy the problem after your written notice. ORS 90.365 then opens three options once a reasonable response time passes:

Buy the service yourself and deduct the actual, reasonable cost from your rent.
Claim a rent reduction based on the diminished rental value during the outage.
Move to substitute housing. You stop paying rent for the period of noncompliance and can recover the cost of comparable temporary housing beyond what your normal rent would have been.

If the lack of an essential service poses an imminent and serious threat to your health, safety, or property, you can give the landlord written notice that the lease will end in 48 hours unless the problem is fixed. That is the strongest remedy, intended for situations like no heat in winter or no running water.⁹

These remedies disappear if you or someone you let into the unit caused the problem. A furnace that fails from landlord neglect triggers full protections. A furnace broken by your guest does not.⁹

Document Everything

Whatever remedy you pursue, documentation decides disputes. Take dated photographs. Keep copies of every written notice you send. Follow up any phone call with a written summary. Save receipts for repairs or substitute housing. A housing code inspector’s report can carry serious weight in court.

Filing a Code Complaint

If the landlord ignores your notice, file a complaint with your local code enforcement agency. These agencies can inspect the property and issue citations. Portland’s code enforcement division accepts housing-condition complaints and prioritizes critical and emergency issues, with reports accepted by phone or online portal.¹⁰¹¹

Suing for Damages

Under ORS 90.360, tenants can recover damages and seek injunctive relief for any landlord noncompliance with the habitability requirements. Recoverable losses include the cost of repairs you paid for, alternative housing expenses during the period the unit was uninhabitable, and compensation for the diminished value of your living conditions.⁸

Oregon small claims court handles disputes up to $10,000, which covers most habitability claims. You don’t need a lawyer, but you do need to itemize every loss with specifics; the court won’t accept a lump-sum guess. Written professional estimates are appropriate for things like home repair costs.¹² Claims over $10,000 go to circuit court, where you’ll probably want an attorney.

Protection From Landlord Retaliation

A lot of tenants hesitate to assert these rights because they worry about payback. Oregon law addresses that directly. Under ORS 90.385, a landlord cannot retaliate by raising your rent, cutting services, serving a termination notice, or threatening eviction after you’ve complained to a government agency about a code violation, exercised rights under the habitability statutes, or organized with other tenants.¹³

Oregon courts recognize a presumption that a landlord’s negative action within six months of your complaint is retaliatory. The burden then shifts to the landlord to show a legitimate, non-retaliatory reason. In practice, a rent hike or termination notice that lands shortly after you reported a code violation is going to look very bad for the landlord in court. A complaint made by someone on your behalf counts as your complaint for these purposes.

If a court finds retaliation, you’re entitled to remedies under ORS 90.375, including damages for financial harm. Retaliation also works as a defense if the landlord tries to evict you. For retaliation tied to habitability complaints, filing in small claims or circuit court under ORS 90.385 is typically your strongest path because the statutory presumption works in your favor. Oregon’s Bureau of Labor and Industries separately handles fair housing complaints involving discriminatory treatment.¹⁴
