The local rulesJames City County, VA
Zoning & raw-land occupancy
Varies locallyJames City County has its own Zoning Ordinance (Chapter 24) with 15 applied districts, each listing by-right and specially permitted uses; raw land occupancy isn't a standalone category so it depends on the district and proposed use. Confirm with the county's Zoning Administrator. source
Dwellings, tiny homes & RVs
RestrictedCounty ordinance treats RVs and camping units as temporary/campground occupancy with occupancy limits, not permanent housing on private land; tiny-home-on-foundation rules under state Appendix Q were not confirmed for this county. source
Building permits & codes
Generally allowedThe county's Building Safety & Permits Division administers the state's Uniform Statewide Building Code and requires permits for most construction, alteration, or repair. source
Septic & composting toilets
Generally allowedSeptic systems require a Health Department permit as part of the state VDH process, administered locally; this is required for single-family building permits. source
Greywater reuse
Unclear - verifyNo James City County-specific greywater ordinance was found; this defers to the state Health Department's general regulation. Ask the local Health Department for specifics.
Rainwater harvesting

Private wells & water rights
Varies locallyVirginia state law names James City County as one of a few localities allowed to adopt well standards stricter than the state minimum; the exact local ordinance wasn't confirmed, so check with the Health Department before drilling. source
Living disconnected from utilities
