Rowlett, TX Fire Regulations: Smoke Detectors (2026)

Rowlett adopts the family of International Codes - including the building, residential, fire, and property-maintenance codes - by ordinance, which is where its smoke-alarm requirements come from rather than a unique standalone city rule. Under the residential/fire code provisions that Texas cities like Rowlett enforce, smoke alarms must be installed in each sleeping room, outside each separate sleeping area in the immediate vicinity of the bedrooms, and on each additional story of the dwelling, including basements. In new construction and major remodels, the alarms must be hardwired with battery backup and interconnected so that activation of one alarm sounds all of them. For existing housing, Rowlett's adopted International Property Maintenance Code (adopted via City ordinance) requires that dwellings be equipped with working smoke alarms in serviceable condition, which the City enforces during fire and rental/occupancy inspections and on complaint. These are nationally standardized requirements applied locally; Rowlett's role is adoption and enforcement, not writing different spacing rules. Carbon monoxide alarms are likewise required by the adopted codes where fuel-fired appliances or attached garages are present. Residents and landlords with questions should contact Rowlett Fire Rescue's fire marshal or the City's Building Inspections division.
