Smoke Detectors: Scottsdale vs Tempe

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

Arizona ARS 36-1637 requires an approved smoke detector in every new residential housing unit and in any sleeping area remodeled under permit. Scottsdale enforces the 2021 International Fire Code (Ordinance 4562, SRC Chapter 36), which generally requires smoke alarms in every sleeping room, outside each separate sleeping area near the bedrooms, and on every story including basements.

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.

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

Under Tempe's Rental Housing Code, which adopts IRC Section R314 and IBC 907, smoke alarms are required inside every bedroom, in the hallway or area immediately outside each sleeping area, and on every story including basements and habitable attics. Wall-mounted alarms must sit 4–12 inches from the ceiling; ceiling units at least 4 inches from any wall. The owner must install, maintain, and verify operation before each new tenancy.

Who is responsible for smoke detectors in a Tempe rental — landlord or tenant?

Both. Under Tempe's Rental Housing Code, the owner is responsible for installation, replacing batteries annually if battery-operated, keeping records, and verifying all detectors are operational before re-occupancy. Under A.R.S. § 36-1637, the tenant must maintain and test the detector during occupancy and give written notice of any malfunction; the landlord must then repair it.
