Wyoming Rental Air Quality and Ventilation Standards

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

If you rent a home or apartment in Wyoming, you have the right to a safe and healthy living environment. Good air quality and proper ventilation are essential to protect you and your household from indoor hazards like mold, smoke, or gas leaks. This guide explains your protections under Wyoming law, your landlord’s responsibilities, and what you can do if your indoor air is unhealthy.

Wyoming Rental Air Quality Laws and Responsibilities

Wyoming law requires all landlords to provide rental units that are fit for human habitation. While Wyoming does not have specific air quality measurement requirements, landlords must ensure the rental is "habitable" and reasonably safe. According to the Wyoming Residential Rental Property Act, rentals must:

  • Provide adequate heating and ventilation
  • Be free of hazardous conditions such as mold from leaks or unvented appliances
  • Ensure all gas appliances and heating units are installed and maintained safely

This means if there is an air quality issue caused by poor ventilation, broken fans, or malfunctioning furnaces, it is typically the landlord’s responsibility to fix it.

Common Air Quality Problems in Rentals

  • Mold or Dampness: Often caused by leaks or inadequate ventilation.
  • Carbon Monoxide: From faulty heaters, stoves, or gas appliances.
  • Smoke Exposure: If there’s secondhand smoke entry or improper exhaust from appliances.
If you notice mold, strong odors, damp walls, or gas smells, notify your landlord right away—these are health hazards that should be addressed quickly.

Steps to Take if You Have Air Quality or Ventilation Issues

If you believe your ventilation isn’t working or the air quality is making you sick, take these steps before seeking formal action:

  • Document the problem (photos, written descriptions, and dates of symptoms or incidents).
  • Notify your landlord about the issue in writing. Keep a copy of all communications.
  • Request repairs or remediation as soon as possible.

If your landlord does not respond or repair the problem, Wyoming law allows you to give a written demand to fix the condition within a "reasonable" time (generally defined as three days for urgent health and safety issues).

Official Notice—Rental Repairs Form (Wyoming)

  • Form: "Notice to Landlord for Required Repairs" (no official numbered form in Wyoming, but written notice is legally required)
  • How and When to Use: Use this when your landlord has not made required repairs affecting health or safety. Clearly describe the air quality or ventilation issue, and give them a reasonable deadline to fix it.

Sample action: "I am providing this written notice that there is mold growth in the bathroom due to a broken vent fan and water leaks. Please repair the fan and address the water issue within three days, per Wyoming law."
