Smoke Detectors: Glendale vs Mesa

Where do I have to put smoke detectors in a Glendale home?

Under the International Residential Code adopted in Glendale Code Chapter 9, alarms must be inside each sleeping room, outside each separate sleeping area in the immediate vicinity of bedrooms, and on each additional story including any basement. New construction and substantial remodels also require interconnection and primary AC power with battery backup. ARS 36-1637 sets the underlying state requirement.

Who is responsible for the smoke detector in a Glendale rental, the tenant or the landlord?

ARS 36-1637 places day-to-day maintenance and battery replacement on the tenant once the alarm is installed. If a tenant gives the landlord written notice that an alarm is malfunctioning, the landlord becomes responsible for the repair. Landlords must also give written notice to tenants at move-in describing these maintenance duties.

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.
