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 rulesNorthampton County, VA
Zoning & raw-land occupancy
RestrictedUnincorporated Northampton County has countywide zoning, with every parcel classified as Resource Protection Area or Resource Management Area under the Chesapeake Bay Preservation Act overlay. Any new construction, land disturbance of 2,500 sq ft or more, or expansion of use requires a zoning clearance or land disturbance permit from the county's Planning, Permitting & Enforcement Department, and RPA encroachment triggers a water quality impact assessment. source
Dwellings, tiny homes & RVs
Unclear - verifyThe zoning ordinance defines manufactured homes (which can count as dwellings) separately from RVs and campers, which it treats as temporary or campground-only uses, so a full-time RV or tiny-house-on-wheels as a primary residence outside a campground is not clearly authorized. I'd call the Zoning Administrator, Michael Starling, to confirm before buying land expecting to live in an RV or THOW full time.
Building permits & codes
Generally allowedThe county's Building Department enforces the state-mandated 2021 Virginia Uniform Statewide Building Code, and a permit is required before construction begins. Extra rules kick in near tidal water (sealed engineering plans, wind-resistant construction) and in the 100-year floodplain (storm-resistant, anchored construction). source
Septic & composting toilets
Generally allowedAny property not on public sewer needs a permit from the Virginia Department of Health for its sewage disposal system before the county will issue a building permit, and applications must include work from a DPOR-licensed private consultant. Northampton's Eastern Shore location makes saltwater intrusion a real local concern, so expect the Health Department to require elevated or mound systems on many sites; composting toilets aren't separately addressed on an official Eastern Shore page I found, so confirm directly with the Health Department. source
Greywater reuse
Generally allowedI didn't find a Northampton County-specific greywater rule, so this falls back to Virginia's state Board of Health regulations. Confirm any system specifics with the Eastern Shore Health District before installing.
Rainwater harvesting
Generally allowedNo county-specific restriction on rainwater harvesting turned up in this research, so it appears to follow the general Virginia state baseline of allowing it. Worth a quick check with the county Building Department if you're tying a cistern into plumbing covered by the building permit.
Private wells & water rights
Generally allowedThe Virginia Department of Health permits private wells (except monitoring wells), with a licensed well driller or onsite soil evaluator confirming proper setbacks and construction, and well permits are often processed alongside septic permits. Because Northampton is on the Eastern Shore, saltwater intrusion is a documented siting issue the Health Department will factor into well placement. source
Living disconnected from utilities
Unclear - verifyI found no county ordinance in Northampton that forces a grid-electric hookup, so living off-grid for power itself isn't barred outright. That said, you still need approved well and septic permits, a zoning clearance, and ultimately a Certificate of Occupancy from the Building Official, so full disconnection from all services still has to clear those separate hurdles. source
