Can you put a tiny home in Virginia?
Current tiny-home-on-wheels and ADU rules for Virginia, sourced and dated — plus verified local builders.
DEPENDS ON LOCATION
Virginia — Local control now; a real statewide law takes effect July 2027 (verified 2026-08)
Tiny home on wheelsNo statewide tiny-home-on-wheels law. Northern Virginia, inside the DC commuter belt, tends to be significantly stricter than rural counties in the southern and western parts of the state.
ADU / accessory unitThis is an important update: Gov. Spanberger signed Senate Bill 531 in April 2026, which will require every locality to allow ADUs by right in single-family zones, cap permit fees at $500, and bar family-relation or excess-setback requirements. However, the law does not take effect until July 1, 2027 — as of this review, current local rules still apply everywhere, including in jurisdictions like Loudoun and Prince William that have no existing ADU ordinance of their own. Alexandria, Arlington, and Fairfax already have their own, separate ADU frameworks that predate SB 531 and will continue to matter alongside it.
Minimum square footageNo statewide minimum currently; SB 531 (effective 2027) will require ADU size limits to be no stricter than those applied to the primary home
Foundation requirementDepends on locality and unit type until the 2027 statewide law takes effect
Local notesTiming matters a lot here: if you're planning now, current local rules apply and vary sharply by jurisdiction. If your timeline extends past July 2027, SB 531 changes the baseline everywhere, though NoVA localities with existing ADU ordinances (Alexandria, Arlington, Fairfax) will still have their own specifics layered on top.
