Oregon Rental Air Quality and Ventilation Rules Explained

Health & Safety Standards Oregon published: June 21, 2025 Flag of Oregon

Your home's air quality directly affects your comfort and health, especially for renters in Oregon. Understanding air quality and ventilation standards helps ensure your landlord maintains a safe and habitable space. This article explains what Oregon law requires for indoor air quality, your rights as a renter, and steps to take if your rental doesn't meet required standards.

What Are Air Quality and Ventilation Requirements in Oregon Rentals?

Oregon law, through the Oregon Residential Landlord and Tenant Act, requires that rental homes be safe, clean, and habitable. This includes maintaining reasonable air quality and adequate ventilation. A rental must:

  • Provide working ventilation in all habitable rooms
  • Contain heating facilities capable of maintaining safe indoor temperatures
  • Be free of chronic moisture problems like leaks or mold
  • Comply with local building and safety codes

The Oregon Residential Specialty Code and local municipal codes further detail ventilation and moisture control requirements.

Examples of Issues Affecting Indoor Air

  • Broken or blocked bathroom and kitchen fans
  • Windows that do not open
  • Unaddressed leaks causing mildew or mold
  • Heating equipment producing fumes

What to Do If Your Rental Doesn't Meet Air Quality Standards

If your home has persistent moisture, visible mold, or outdated ventilation, Oregon law gives you the right to notify your landlord. They are responsible for making necessary repairs. Start by notifying your landlord in writing (email or letter) with clear details and photos, if possible.

Key Steps for Renters

  • Document the issue (photos, dates, detailed notes)
  • Send a written request to your landlord describing the problem
  • Allow reasonable time for repairs (usually 30 days for non-emergencies)
  • If unresolved, consider filing a formal complaint
If your landlord fails to fix hazards like mold or broken ventilation, you can file a complaint with your local code enforcement department or seek help from tenant advocacy organizations.

Official Forms and How to Use Them

  • Request for Repairs Notice (No official statewide form, sample available from some city websites):
    When to use: Send this written notice to your landlord if you experience poor air quality, mold, leaks, or ventilation problems. Clearly describe the issue and request a timeline for repairs.

  • Rental Housing Complaint Form (varies by city/county):
    When to use: If issues persist, submit this form to your city or county code enforcement office. For example, tenants in Portland can use the online rental complaint form.

Dispute Resolution and Tribunals

When repairs are not made, renters may file a case in county circuit court. Oregon does not have a specialized landlord-tenant tribunal, but county Circuit Courts handle residential tenancy disputes. Find details through the Oregon Judicial Department – Circuit Courts page.
