Smoke Detectors: Chandler vs Phoenix

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

Under the 2018 IFC Section 907.2.11 and 2018 IRC Section R314 adopted by reference in Chandler City Code Chapter 19, smoke alarms must be installed inside each sleeping room, outside each separate sleeping area in the immediate vicinity of bedrooms, and on each story of the dwelling including basements. New-construction alarms must be hardwired, interconnected, and have a battery backup.

Who is responsible for the smoke alarm in a Chandler rental, the tenant or the landlord?

Under Arizona Revised Statutes § 36-1637, the tenant is responsible for keeping the smoke alarm operable, including replacing batteries, unless the tenant gives written notice to the landlord that the alarm is malfunctioning. Once the landlord receives that written notice, the landlord must repair or replace the alarm. Confirm any local amendments with Chandler Fire Prevention at 480-782-2120.

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.
