Read this before you act on anything below. This is my researched starting point for Jefferson 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 rulesJefferson County, WV

Zoning & raw-land occupancy

RestrictedJefferson County has adopted a countywide Zoning and Land Development Ordinance and Subdivision Regulations, so raw-land use depends on the zoning district. This differs from many unzoned WV counties. source

Dwellings, tiny homes & RVs

Unclear - verifyNo specific county rule on tiny-home or RV permanent occupancy was found. Confirm directly with the Office of Planning and Zoning. source

Building permits & codes

RestrictedThe county's Building Code Enforcement Ordinance requires compliance with the IRC/IBC (most recent version adopted by West Virginia) for most structures, including sheds, garages, and additions, and permits are required through the Office of Building Permits & Inspections. source

Septic & composting toilets

Generally allowedThe Jefferson County Health Department administers its own onsite sewage disposal permitting, requiring soil investigation and plan review before installation. Composting toilets specifically are not addressed, so ask JCHD.

Greywater reuse

Unclear - verifyNo county-specific greywater ordinance was found; it likely falls under JCHD's general onsite wastewater permitting and the state's design-standards framework, but this is not confirmed.

Rainwater harvesting

Unclear - verifyNo Jefferson County rule on rainwater harvesting was found; this appears to inherit the state's general unregulated stance on non-potable use, but is not confirmed at the county level.

Private wells & water rights

Varies locallyPrivate wells follow the state's well certification program, but Jefferson County Health Department requires subdivision review, including minimum lot size, for land not served by public sewer.

Living disconnected from utilities

Unclear - verifyNo explicit rule requiring utility hookup was found, but the building code and septic-before-building-permit sequence functionally require code-compliant construction and approved wastewater even off the electric grid. source
