Smoke Detectors: Mesa vs Phoenix

Does Mesa have its own smoke detector ordinance?

No. Mesa enforces Arizona Revised Statutes Sec. 36-1637 and the International Fire Code adopted through Title 7 of the Mesa City Code rather than a stand-alone city smoke alarm ordinance. ARS 36-1637 requires an approved smoke detector in every new residential unit and in any existing unit where a sleeping area is remodeled with a permit. Mesa Fire and Medical also recommends monthly testing and replacing alarms every 10 years.

Who is responsible for smoke alarms in a Mesa rental, the landlord or the tenant?

Arizona ARS 36-1637 makes the tenant responsible for keeping the alarm operable, including testing it and replacing batteries. If the tenant gives the landlord written notice that a smoke detector is malfunctioning, the landlord must repair it. Landlords must also provide tenants with written notice of these responsibilities. Mesa enforces this state framework.

Where do smoke alarms have to be installed in a Phoenix home?

Under the 2018 Phoenix Building Construction Code (Chapter 9, IRC R314), smoke alarms are required inside every bedroom, in the hallway or area immediately outside each sleeping area, and on every story of the dwelling, including basements and habitable attics. All alarms within a single unit must be interconnected so one alarm triggers them all. Confirm details with Phoenix Planning & Development at 602-262-7811.

What kind of smoke alarm batteries does Phoenix require?

Phoenix Ordinance G-5898 (effective April 18, 2014) requires that battery-operated smoke alarms sold or installed in the city be UL-listed units with a sealed, non-removable 10-year lithium battery. No smoke alarm may be used more than 10 years past its date of manufacture; check the back of the unit and replace if older. For rental homes, A.R.S. § 36-1637 makes the landlord responsible for repairs after written tenant notice.
