Read this before you act on anything below. This is my researched starting point for Berkeley County, WV, not legal advice and not a guarantee. 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 rulesBerkeley County, WV

Zoning & raw-land occupancy
Varies locallyMost of Berkeley County is unzoned; the Tuscarora and Windewald Districts are zoned, and incorporated towns (Martinsburg, Hedgesville, etc.) set their own separate zoning. The county's Subdivision Regulations and Planning Department otherwise govern land use. source
Dwellings, tiny homes & RVs
Unclear - verifyNo specific Berkeley County ordinance on RV or tiny-home occupancy was confirmed; the county building code likely applies if used as a permanent dwelling. Confirm with the Planning Department or Building Permits office.
Building permits & codes
RestrictedBuilding permits are required countywide outside incorporated towns, enforced by the county's Building Permits and Inspections Department under adopted 2018 IRC/IBC-family codes.
Septic & composting toilets
Generally allowedA septic permit from the Berkeley County Health Department is required before a building permit is issued, per state Sewage System Rule 64 CSR 9 design standards. source
Greywater reuse
RestrictedNo distinct county greywater ordinance was found; it appears to fall under the same Health Department sewage-permitting process. Not confirmed as a separate rule. source
Rainwater harvesting
Unclear - verifyNo county ordinance on rainwater collection was found; this likely follows the state's generally unregulated approach for non-potable use, but it's not confirmed.
Private wells & water rights
Generally allowedWells require a certified driller and a permit per 2008 state legislation, built to minimum design standards; the county Health Department also offers water testing. source
Living disconnected from utilities
Generally allowedNo county rule mandates electric hookup; a building permit needs well/septic permits or utility availability letters, so a fully off-grid well-and-septic home can satisfy permitting. source
