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

Zoning & raw-land occupancy
Generally allowedMineral County has no countywide zoning ordinance; the only land-use rule on the books regulates exotic-entertainment business locations, per the county Planning Commission. Incorporated towns (Keyser, Piedmont, Ridgeley, Carpendale, Elk Garden) may zone separately; not researched here. source
Dwellings, tiny homes & RVs
Unclear - verifyNo Mineral County page specifically addresses RV or tiny-home occupancy. With no general zoning ordinance, it's not clearly restricted on unincorporated land, but any structure still triggers building-permit and septic-approval requirements. Ask the County Planning Office, and check town codes separately.
Building permits & codes
RestrictedMineral County requires a building permit for structures including houses, additions, sheds, and garages, per the Planning Commission; permits are coordinated through the Mineral County Health Department since 2019 and require proof of septic approval or sewage service. A separate floodplain ordinance also applies in mapped flood areas. source
Septic & composting toilets
Generally allowedA permit from the Mineral County Health Department is required to install, repair, or modify a septic system, under West Virginia's statewide onsite-sewage rules. No county-specific composting-toilet allowance was found; that's not confirmed, so ask the Health Department directly.
Greywater reuse
Unclear - verifyNo Mineral County-specific greywater ordinance was found. It's treated as falling under the state's general onsite-sewage design-approval standards, enforced locally by the county Health Department.
Rainwater harvesting
Generally allowedNo restriction on rainwater collection itself was found. If a cistern is used as a household water source, it goes through the county Health Department's water-supply application process alongside wells and springs.
Private wells & water rights
Generally allowedWells are regulated under West Virginia's statewide well program (certified drillers, required permits, minimum design standards), with applications and water testing handled by the Mineral County Health Department.
Living disconnected from utilities
Varies locallyNo Mineral County ordinance mandates connection to public utilities. In practice, building permits require proof of septic approval or sewage service, and state rules require a compliant well if using groundwater, so off-grid living is workable only if those approvals are met. source
