Town Code Title 5 adopts the IRC, requiring smoke alarms in every bedroom, outside sleeping areas, and on each level. New construction needs interconnected alarms with sealed 10-year batteries.
Oro Valley Town Code Title 5 (Building Regulations) adopts the International Residential Code with local amendments. Smoke alarms must be installed in each sleeping room, outside each sleeping area in the immediate vicinity of the bedrooms, and on each additional story of the dwelling including basements. New construction and remodels requiring a permit must install interconnected smoke alarms so that activation of one alarm triggers all alarms in the dwelling. Sealed lithium-battery alarms with a 10-year lifespan are required in new construction per the 2018 IRC as adopted. Existing homes must maintain working smoke alarms; battery replacement is the homeowner's responsibility. The Golder Ranch Fire District serves Oro Valley and conducts inspections during the building permit process. Combination smoke-carbon monoxide detectors are accepted where CO detection is required. Desert climate with low humidity can cause false alarms from dust accumulation, and the fire district recommends regular cleaning of detector sensors.
Failure to install smoke alarms in new construction: building permit will not receive final approval. Existing homes: code enforcement can issue notice of violation. Landlords must provide working smoke alarms per Arizona Residential Landlord and Tenant Act (ARS 33-1324).
