Smoke Detectors: Mesa vs Tempe

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 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.
