Arizona Renters: Laws on Smoke and Carbon Monoxide Detectors

Staying safe in your Arizona rental home means knowing your rights around smoke and carbon monoxide detectors. Many renters are unsure who must provide these life-saving devices, or what steps to take if they're missing or malfunctioning. This guide breaks down current Arizona laws on smoke and carbon monoxide alarms, explains your protections, and tells you what to do if your rental isn’t up to standard.

Arizona’s Health & Safety Standards for Rental Housing

The Arizona Residential Landlord and Tenant Act sets out health and safety standards every landlord must meet. Under A.R.S. § 33-1324, landlords are required to keep rental properties “in a fit and habitable condition” and to comply with applicable building and housing codes. Smoke detector requirements are often established through these building codes.

Smoke Detector Laws in Arizona Rentals

Arizona state law requires smoke detectors in all newly constructed or remodeled residential buildings, including rentals. Local municipalities may also enforce their own ordinances. Here’s what most renters can expect:

• Rental properties must have functioning smoke detectors installed in accordance with the state building code and local ordinances.
• Landlords are responsible for providing and installing smoke alarms, typically in bedrooms and halls.
• Tenants must keep detectors free of obstruction and test batteries regularly (unless the device uses a 10-year sealed battery or is hardwired).
• If a detector is missing or not working, tenants should promptly notify the landlord in writing.

To find local-specific rules, check with your city or county’s building or fire department. For example, the Phoenix Fire Department enforces city smoke alarm requirements based on the adopted code.

Are Carbon Monoxide Detectors Required in Arizona Rentals?

Currently, Arizona state law does not require landlords to install carbon monoxide (CO) detectors in all rental units. However, some cities and counties may have local requirements, especially for newer buildings or homes with fuel-burning appliances (like gas stoves, fireplaces, or heaters).

If your unit has any fuel-burning device or an attached garage, installing a CO detector is strongly recommended—even if not strictly required by law. You can ask your landlord to provide one or offer to install a battery-operated unit at your expense (with written permission).

Your Rights and What to Do if Smoke or CO Alarms Are Missing

Landlords in Arizona must ensure smoke detectors are present when you move in. If you notice a smoke alarm is missing, disabled, or not working, you have the right to notify your landlord and request a prompt repair or installation.

• Notify your landlord in writing — keep a copy for your records.
• Allow a reasonable time for the landlord to fix the issue (generally within 10 days for non-emergency maintenance).
• If ignored, you may report unsafe conditions to your local city housing/code enforcement office.
• You may also consider giving a “Notice of Intent to Terminate” if the problem is not fixed, as outlined under the Arizona Residential Landlord and Tenant Act (A.R.S. § 33-1361).

Forms and Steps for Arizona Renters

You may need to use official forms if your landlord does not address required smoke detector repairs:

• Arizona Residential Landlord-Tenant Act 10-Day Notice to Remedy or Quit
  View the official form (PDF).
  When to use: If your landlord fails to repair or install a smoke detector after you’ve notified them, complete and deliver this written notice. For example, if you emailed the landlord about the missing smoke alarm but received no response after several days, fill out the form and deliver it according to the instructions. If they still don’t act in 10 days, you may have grounds to end your lease or seek legal help.

Name of Tribunal or Board for Tenant Issues

In Arizona, disputes over rental housing are generally handled in local Justice Courts (sometimes called landlord-tenant court). These courts review tenant complaints, landlord obligations, and repair issues under state law.

FAQ: Arizona Renters’ Smoke and CO Detector Questions

1. Who is responsible for installing and maintaining smoke detectors in Arizona rentals?
   Landlords must provide and install smoke detectors as required by building codes, while tenants must keep them operational (e.g., replacing batteries in battery-powered models).
2. Are carbon monoxide detectors legally required in all Arizona rental properties?
   No, Arizona state law does not require CO detectors in all rental units, but certain local codes or property types (such as new builds with gas appliances) may require them.
3. What should I do if my landlord will not fix or replace a missing smoke detector?
   Notify your landlord in writing, allow a reasonable time for repair, then use the 10-Day Notice to Remedy form if there is no action. You may also contact your local housing code office or file a case in Justice Court if conditions remain unsafe.
4. Can I install a carbon monoxide detector myself if my landlord hasn’t provided one?
   Yes, with your landlord’s written permission, you may install a battery-operated CO detector if not already provided—this is a good safety practice in homes with gas appliances.
5. Does my city or town in Arizona have stricter rules than state law for smoke and CO alarms?
   Many municipalities adopt their own building codes which may be stricter than state law. Contact your local housing or fire department to learn about the requirements for your area.
