Smoke Detectors: Gilbert vs Phoenix

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

Under the 2018 International Residential Code (Section R314), which Gilbert enforces, smoke alarms are required inside each sleeping room, outside each separate sleeping area in the immediate vicinity of the bedrooms (typically the hallway), and on every additional story of the dwelling, including basements and habitable attics. All alarms within a single unit must be interconnected so that activation of one alarm sounds them all.

Who is responsible for smoke detectors in a rented Gilbert home?

Under A.R.S. § 36-1637, the landlord must install approved smoke detectors when housing is built or when a sleeping area is remodeled under a building permit, and must repair detectors after receiving written notice from the tenant. The tenant is responsible for routine testing, replacing batteries, and providing that written notice if a unit fails. Confirm any local amendments with Gilbert Fire & Rescue at 480-503-6300.

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

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.
