Prince William County is not in a state-designated wildfire (WUI) zone, so there is no California-style defensible-space mandate. Wildfire risk is managed through Virginia's spring 4 p.m. burn law, DEQ open-burning limits, and the county's tall-grass ordinance.
Unlike wildfire-prone Western states, Virginia does not designate wildland-urban-interface (WUI) zones with mandatory defensible-space clearance around homes, and Prince William County adopts no such requirement. Wildfire risk is instead controlled through the statewide 4 p.m. Burn Law (VA Code § 10.1-1142), which bans outdoor fires near woodland before 4 p.m. from February 15 through April 30, plus Virginia DEQ open-burning restrictions (9VAC5-130) and the county's Tall Grass & Weeds ordinance that keeps vegetation under 12 inches. Residents near forested land should follow Firewise voluntary guidance, but no county ordinance compels vegetation-clearance zones.
There is no defensible-space penalty; enforcement runs through the burn-law (misdemeanor), DEQ air-rule violations, and the tall-grass ordinance's notice-and-abatement process with cost recovery.
