Arlington, TX Fire Regulations: Smoke Detectors (2026)

Arlington enforces smoke detector requirements through Texas Health and Safety Code Chapter 766, the 2021 International Residential Code, and Property Code §92.251 governing rental dwellings. Every one- and two-family dwelling, townhouse, and multifamily unit must have a working smoke alarm installed inside each sleeping room, outside each separate sleeping area in the immediate vicinity of bedrooms, and on each story including basements. Alarms must be interconnected in homes built or substantially remodeled after 2009 so that activation of one triggers all. For existing homes without hardwired systems, battery-only alarms are acceptable but when they reach end of life they must be replaced with sealed 10-year lithium battery units per Chapter 766.0251. In rental properties, landlords bear full responsibility for installation and maintenance: tenants may not remove, disable, or fail to report inoperative alarms, and landlords must inspect at each tenancy turnover. A tenant may send a written demand for repair and, if the landlord fails to act within a reasonable time, recover one month's rent plus $100, actual damages, court costs, and attorney's fees under Property Code §92.260. Arlington Fire Department offers free smoke alarms to qualifying low-income residents through the Home Safety Program.
