Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.
The local rulesKing George County, VA
Zoning & raw-land occupancy
RestrictedKing George County has countywide zoning administered by Planning & Zoning, with districts like R-2 and agricultural zones setting dimensional standards. This differs from unzoned rural Virginia counties; check your parcel's district before planning any structure. source
Dwellings, tiny homes & RVs
Unclear - verifyNo county-specific rule on tiny houses or long-term RV occupancy as a dwelling was confirmed; likely inherits Virginia's general treatment of RVs as non-dwellings, but confirm with Planning & Zoning. source
Building permits & codes
Generally allowedBuilding permits are required and administered by the county Building Inspections office under the state's Uniform Statewide Building Code (2021 Virginia Construction Code). source
Septic & composting toilets
Generally allowedSeptic systems require a site evaluation and construction permit from the Virginia Department of Health's Rappahannock Area Health District before installation; the county Building Department collects pump-out inspection reports. source
Greywater reuse
Unclear - verifyNo county-specific greywater ordinance or guidance was found; this likely routes through the same VDH health district office that handles septic, but ask them directly to confirm.
Rainwater harvesting
Unclear - verifyNo King George County rule on rain barrels or rainwater catchment was found; not confirmed at the county level, so this likely defaults to general state guidance.
Private wells & water rights
Generally allowedPrivate wells are reviewed and approved by VDH's Rappahannock Area Health District, and are common outside areas served by the King George County Service Authority's water systems. source
Living disconnected from utilities
Varies locallyProperties outside King George County Service Authority coverage can generally rely on private well and septic without grid hookup, but properties adjacent to existing public water/sewer lines can be required to connect per Service Authority regulations, subject to state law limits. source
