Wyoming Smoke and Carbon Monoxide Detector Laws Explained

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

As a renter in Wyoming, keeping your home safe is a shared responsibility between you and your landlord. Many renters are unsure who must provide and maintain smoke or carbon monoxide detectors. This article discusses Wyoming’s current laws about these vital safety devices, what your landlord must do, and what steps you can take if your alarms are missing or not working.

What Are Landlords Responsible for in Wyoming?

Wyoming law requires all residential rental properties to be safe and habitable. One crucial safety measure is the installation and maintenance of smoke detectors. For many newer properties, carbon monoxide detectors are also necessary. State and many local building codes outline exact requirements, especially for dwellings built or remodeled after 2010.

  • Smoke Detectors: Landlords must install and maintain working smoke alarms in every rental unit.
  • Carbon Monoxide Detectors: Required in rental units with fuel-burning appliances or attached garages, typically in homes constructed or renovated after 2010.
  • Detectors must be placed outside sleeping areas and on each floor, as specified by local building codes.

For the most current code, refer to the Wyoming Department of Fire Prevention and Electrical Safety.

What Are Renters Responsible For?

As a Wyoming renter, you must do the following:

  • Test alarms regularly (usually monthly) and change batteries if needed
  • Promptly notify your landlord in writing if a detector malfunctions or is missing
  • Do not disable, remove, or tamper with installed detectors

If your unit lacks required detectors or they do not work after your request, you may have remedies under state law. The Wyoming Residential Rental Property Act covers your right to a habitable dwelling and a safe environment.[1]

Addressing Detector Issues: Steps for Renters

If you notice your smoke or carbon monoxide detectors are missing, defective, or you’re unsure of their status, follow these steps:

  • Document the issue with photos and a brief written description
  • Notify your landlord in writing (email is acceptable) as soon as possible
  • Allow a reasonable amount of time for repairs, usually as outlined in your lease or local ordinances
Tip: Always keep copies of your notifications and responses for your records. This helps if you need to take the issue further.

Wyoming Forms and Official Action Steps

Wyoming does not have a state-level "habitability complaint" form. However, you may use a written notice (such as a letter or email) requesting repairs. If your landlord fails to act, you may:

If you proceed to court, you may need the "Complaint for Forcible Entry and Detainer" (available from your local circuit court). This form is mostly used for eviction but may be involved in habitability disputes. See Wyoming Circuit Court Forms for details.

Relevant Law and Enforcement

Wyoming’s Residential Rental Property Act (Title 1, Chapter 21, Article 12 of the Wyoming Statutes) requires landlords to provide safe and habitable premises. These standards include fire and carbon monoxide safety, as outlined in building and fire codes. Enforcement and disputes typically go through the Wyoming Circuit Courts.

Frequently Asked Questions

  1. Are carbon monoxide detectors required in all Wyoming rentals?
    Not in every unit—only those with fuel-burning heat sources or attached garages, and primarily in buildings constructed or remodeled after 2010. Check with your local code official for specifics.
  2. Who replaces smoke detector batteries in my apartment?
    Generally, renters are responsible for routine battery replacement, unless otherwise stated in your lease. Landlords must replace non-working detectors when notified.
  3. What can I do if my landlord does not fix a faulty smoke detector?
    Notify your landlord in writing and give a reasonable response time. If the issue is still unresolved, contact your local fire department, code enforcement, or consider legal options through the Wyoming Circuit Court.
  4. Can I install my own detectors if there are none?
    You may provide your own for added safety, but the landlord is still legally responsible for meeting safety code requirements in the rental unit.
  5. Where can I find official Wyoming forms or file a habitability complaint?
    Use a written repair request first. For further action, visit your local city or county website or see Wyoming Circuit Court Forms.
