Tiny home rules in Prince William County, VA — covering tiny houses on wheels (THOWs), park model RVs, and tiny home on foundation builds — determine where they are legal and how they get permitted.
Prince William County's Zoning Ordinance bars a detached accessory structure from being used as a dwelling, so a backyard tiny home is not allowed as an independent residence today. Any dwelling must meet full zoning and the Virginia building code. Statewide ADU rights arrive July 1, 2027.
Chapter 32's accessory-use rules state that detached accessory structures in residential and agricultural districts cannot be used as a dwelling. A movable tiny home on wheels is also treated as an RV/recreational vehicle, which cannot be used as permanent living quarters on a residential lot. A permanent tiny house on a foundation must satisfy the Virginia Uniform Statewide Building Code and the district's dwelling and setback standards. Virginia SB 531 will create an accessory-dwelling-by-right in single-family zones effective July 1, 2027; until then, backyard second units depend on the county's zoning provisions. Contact Zoning Administration (703-792-6830) before siting any tiny home.
Occupying a tiny home or RV as a dwelling on a residential lot without approval is a zoning violation subject to notices, required removal, and civil penalties.
