Wyoming Landlords and Radon Testing: Renter Rights Explained

Health & Safety Standards Wyoming published: June 21, 2025

If you're renting a home or apartment in Wyoming, you might wonder whether your landlord is required to test for radon—a naturally occurring radioactive gas that can pose serious health risks if it builds up indoors. Understanding these rules can help keep your home safe and ensure your landlord meets their responsibilities under state law.

What is Radon and Why Does it Matter for Renters?

Radon is a colorless, odorless gas that forms naturally from soil and rocks. Long-term exposure to elevated radon levels can increase the risk of lung cancer. The U.S. Environmental Protection Agency (EPA) lists radon as a significant indoor air health issue. Testing for radon is simple but critical, especially in areas known to have higher radon risks—such as parts of Wyoming.

Radon Testing Requirements for Wyoming Landlords

As of 2024, Wyoming has no statewide law that mandates landlords to test for radon or disclose radon test results to tenants before or during a tenancy. This means:

There is no specific law requiring landlords to perform radon testing before renting out a unit.
Landlords do not have to provide radon test results or warnings to renters under Wyoming law.
However, the EPA and the Wyoming Department of Health both recommend radon testing in residential properties.

If you are concerned about radon, you can ask your landlord about any previous testing or consider performing a test yourself. Low-cost radon test kits are available at hardware stores and through the Wyoming Radon Program.

The Landlord’s Duty: General Health & Safety Standards

Although Wyoming law does not mention radon specifically, landlords must provide safe and habitable rental units under the Wyoming Residential Rental Property Act.^[1] This generally includes:

Supplying heat, water, electricity, and plumbing in working order
Maintaining the structure so it does not endanger tenants’ safety
Complying with building and health codes that materially affect health and safety

If you believe a radon issue is making your rental unsafe and your landlord refuses to act, you may have options under habitability rules. Always document your concerns in writing.

Relevant Official Forms & How to Use Them

Wyoming Complaint Form for Unsafe Housing Conditions (no designated statewide number):
If you believe high radon constitutes a safety hazard, you can report housing condition complaints to your local Public Health Department or code enforcement office. While no universal state form exists, most counties provide a local complaint form. Example: If you are a renter in Natrona County concerned about radon, you would submit a housing or environmental health complaint through the Casper Code Enforcement page. Statewide, renters may wish to consult the Department of Health site for contacts.

If you request radon testing or remediation, keep written records of all communication with your landlord and any results you obtain. This can support your case if habitability becomes an issue.

If You Find High Radon in Your Rental: What Next?

If you perform a test and find levels above the EPA’s recommended action level (4.0 picocuries per liter), consider these action steps:

Notify your landlord in writing and provide a copy of the test results.
Request remediation or ask the landlord to consider mitigation measures.
If your landlord does not respond, check if your local health or housing department can assist based on habitability standards.

Wyoming law is limited in providing specific remedies here, but general requirements for safe and habitable housing still apply.

Which Board or Tribunal Handles Tenancy Issues in Wyoming?

Wyoming does not have a dedicated residential tenancy tribunal. Disputes related to habitability or landlord-tenant law are generally handled by the Wyoming Circuit Courts in the county where the property is located.^[2]

Relevant Tenancy Law in Wyoming

The main law covering landlord and tenant duties is the Wyoming Residential Rental Property Act (W.S. 1-21-1201 through 1-21-1211).^[1] This text sets the basic standards for habitability and landlord obligations in rental housing.
