Oklahoma City, OK Fire Regulations: Smoke Detectors (2026)

Oklahoma City has adopted the International Residential Code smoke alarm requirements, which mandate UL-listed smoke alarms inside every sleeping room, in the hallway or area outside each sleeping area, and on every story of the dwelling including basements. In new construction and in dwellings undergoing major remodels or additions valued above approximately $1,000, alarms must be hardwired to the home's electrical system, interconnected so that activation of one triggers all, and equipped with battery backup.

For existing homes without major remodels, battery-operated alarms are acceptable, but 10-year sealed-battery alarms are strongly recommended and required in some rental situations. Carbon monoxide alarms are required when the home has fuel-fired appliances, an attached garage, or a fireplace. Landlords must provide working alarms at the start of each tenancy and test them during move-in inspections, though tenants are typically responsible for replacing batteries during their tenancy unless the lease states otherwise. The Oklahoma City Fire Department offers free smoke alarms and installation to qualifying residents through its Smoke Alarm Program; call (405) 297-3314 to request. Tampering with or disabling alarms can result in fines up to $500 and, in rental properties, potential lease violations.
