Mesa FAQ
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.
