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.

The local rulesCulpeper County, VA
Zoning & raw-land occupancy
RestrictedCulpeper County has adopted full countywide zoning with fifteen districts, administered by the Planning and Zoning Department; allowed uses vary by district, so raw land occupancy needs a district-specific check. source
Dwellings, tiny homes & RVs
Varies locallyModular homes built to the state building code are allowed in most districts; manufactured/mobile (HUD-code) homes are limited to the A-1 agricultural district, per the county's Planning and Zoning FAQ. Tiny homes on wheels are generally treated as RVs, and long-term occupancy on raw land is not confirmed. source
Building permits & codes
Generally allowedVirginia's Uniform Statewide Building Code is enforced locally by the Culpeper County Building Department, which requires permits and inspections; projects with private septic/water also need a Health Permit. source
Septic & composting toilets
Generally allowedSeptic systems require a permit from the Culpeper County Health Department, consistent with Virginia Department of Health standards under state Title 32.1 and related regulations. source
Greywater reuse
Generally allowedGreywater reuse is permitted under state Board of Health regulations (Title 32.1); no Culpeper-specific ordinance adds to or restricts this state baseline. source
Rainwater harvesting
Generally allowedRainwater harvesting is regulated at the state level by the Board of Health and DEQ, with small-scale use generally exempt; the county defers to this state standard without local additions. source
Private wells & water rights
Varies locallyPrivate wells need a permit through the Culpeper County Health Department under state VDH rules, but the county code allows wells to be prohibited within designated Water and Sewer Authority service areas in favor of mandatory public connection.
Living disconnected from utilities
Unclear - verifyNo standalone rule was found requiring electric grid connection, but parcels within a designated Water and Sewer Authority service area may be required to connect to centralized water/sewer instead of using a well or septic; this is not confirmed as a county-wide restriction on land outside those areas.
