Summary

Virginia's Statewide Fire Prevention Code and Uniform Statewide Building Code require working smoke alarms in dwellings. Landlords must install and maintain them and certify annually; tenants may not disable them. Alarms may be battery-powered or AC-powered.

These county ordinances apply to unincorporated areas of Prince William County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

The tenant shall... not remove or tamper with a properly functioning smoke alarm installed by the landlord, including removing any working batteries, so as to render the alarm inoperative, and shall maintain the smoke alarm in accordance with the uniform set of standards for maintenance of smoke alarms established in the Statewide Fire Prevention Code.

Full Breakdown

Smoke alarm rules in Prince William County come from Virginia's Statewide Fire Prevention Code (§ 27-94 et seq.) and Uniform Statewide Building Code, which apply uniformly across the Commonwealth. In rental housing the landlord must install smoke alarms without retrofitting the site, maintain them in good working order, and certify annually that they are installed and working. Alarms may be battery-operated or AC-powered. Tenants must not remove or tamper with a properly functioning alarm or its batteries, and must report malfunctions to the landlord in writing. On written request, a landlord must add a carbon-monoxide alarm within 90 days.

Violations & Fines

A tenant who disables a working smoke alarm violates VA Code § 55.1-1227; landlords failing to maintain or certify alarms breach the Fire Prevention Code and landlord-tenant duties, enforceable by the Fire Marshal and the courts.
