Plano, TX Fire Regulations: Smoke Detectors (2026)

Smoke-alarm requirements in Plano derive from three layers. Texas Health and Safety Code Chapter 766 mandates that all one and two-family dwellings have operating smoke alarms inside or just outside each sleeping area and on every story. Texas Property Code Section 92.254 requires rental-property landlords to provide and maintain working smoke alarms in every bedroom and on each level, inspected at lease start. Plano adopts the 2021 International Residential Code and 2021 International Fire Code, both of which require hard-wired interconnected smoke alarms with battery backup in new single-family construction, additions over 1,000 square feet, and substantial remodels. Existing homes must at minimum maintain battery-operated alarms in each bedroom, outside each sleeping area, and on every level including basements. The Plano Fire Department runs a free smoke-alarm installation program for eligible residents through community risk reduction, and the Red Cross Sound the Alarm program visits Plano neighborhoods annually. Carbon monoxide alarms are additionally required in dwellings with fuel-burning appliances or attached garages under the IRC.
