Tulsa, OK Fire Regulations: Smoke Detectors (2026)

Tulsa enforces smoke alarm requirements through the adopted International Residential Code, International Fire Code, and state statutes governing residential rental property. In any dwelling unit, smoke alarms must be installed inside each sleeping room, outside each separate sleeping area within 10 feet of bedroom doors, and on every additional story of the home including habitable attics and basements. New construction, additions, and substantial remodels (generally projects that open wall cavities or require a building permit beyond cosmetic work) trigger the full modern standard: 120-volt hardwired alarms with battery backup, interconnected so that one alarm triggers them all. Existing homes not undergoing remodeling may rely on 10-year sealed battery alarms that meet UL 217 standards. Carbon monoxide alarms are required in dwellings with fuel-burning appliances, attached garages, or fireplaces, installed outside sleeping areas. Landlords in Tulsa must deliver the unit with working alarms at the start of every tenancy and test them at turnover. Tenants are responsible for replacing batteries during occupancy, but the property owner must replace any alarm that fails. The Tulsa Fire Marshal investigates complaints about missing or disabled alarms, and tampering with a required alarm is a code violation. Fatal Tulsa house fires in recent years have repeatedly involved missing or non-functioning smoke alarms, and the Fire Department runs a free smoke alarm installation program for residents who cannot afford one.
