Vienna, VA Fire Regulations: Smoke Detectors (2026)

The Town of Vienna enforces the smoke alarm provisions of the Virginia Uniform Statewide Building Code (USBC) and Statewide Fire Prevention Code (SFPC), which are mandatory minimum standards applicable to all dwellings. Smoke alarms must be installed in each sleeping room, in the hallway or area immediately outside each separate sleeping area, and on every story of the dwelling including habitable basements. In new construction and during substantial renovations, alarms must be hardwired to the electrical system with battery backup and interconnected so that activation of one alarm sounds all alarms. Existing single-family dwellings built before interconnection requirements may continue with battery-only alarms if they were compliant when installed, but replacement alarms should follow current standards where feasible. Carbon monoxide alarms are required in dwellings with any fuel-burning appliance (gas furnace, gas water heater, gas range, wood stove, fireplace) or attached garage, installed outside each sleeping area. Under VA Code 55.1-1227, landlords must provide and maintain smoke alarms in rental units, test and replace batteries at the start of each tenancy, and service alarms within five days of written tenant notice of malfunction. Tenants are responsible for routine battery replacement during occupancy unless the lease says otherwise. Alarms should be replaced every ten years per manufacturer specifications, and CO alarms every five to seven years. Tampering with or disabling a required alarm is a Class 3 misdemeanor. Failure to maintain can void homeowner insurance claims in the event of fire and may expose landlords to negligence liability.
