Smoke Detectors: Phoenix vs Scottsdale

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.

Arizona ARS 36-1637 requires an approved smoke detector in every new residential housing unit and in any sleeping area remodeled under permit.

Who is responsible for fixing a broken smoke alarm in a Scottsdale rental?

Under ARS 36-1637, the tenant must keep the alarm operable, but once the tenant gives the landlord written notice that the device has malfunctioned, the landlord becomes responsible for the repair. Landlords must also give tenants written notice of these duties. Short-term rental hosts licensed under Scottsdale Ordinance 4566 must additionally post a laminated 14-point notice identifying the location of smoke alarms and fire extinguishers near the main doors.
