Off-Grid Living in Jefferson County, West Virginia

I'll be upfront: Jefferson County is one of the trickier spots in West Virginia to research because it's actually more regulated than most of the state. A lot of WV counties have no zoning at all, but Jefferson County has adopted a countywide Zoning and Land Development Ordinance (amended as recently as January 2026, per the county's own site) plus a full Subdivision and Land Development Regulations package. So if you're picturing "wide-open unzoned West Virginia land," that's not quite the reality here.

Zoning: The county's Office of Planning and Zoning administers a zoning map with districts, and what you can do with raw land depends on which district it falls in. This is a county-level rule, not a state one, so it's worth calling Planning and Zoning before you buy or build anything.

Dwellings, tiny homes, RVs: I could not find county text that specifically addresses long-term RV or tiny-home occupancy. Given the ordinance is under revision, I'd treat this as unconfirmed and call the Planning and Zoning office directly.

Building codes: Jefferson County has its own Building Code Enforcement Ordinance requiring compliance with the IRC and/or IBC (whichever version the state has most recently adopted). This is broad, covering everything from sheds and detached garages to wood stoves and fences over a certain height. Practically all construction needs a permit through the Office of Building Permits & Inspections.

Septic: The Jefferson County Health Department runs its own onsite sewage permitting program, separate from just relying on the state baseline. You (or an engineer, surveyor, or soil scientist you hire) submit soil investigation results and a plot plan, and JCHD's Environmental Health Specialists review it. Permits do expire and aren't transferable, per JCHD. Composting toilets specifically weren't addressed in anything I found, so I'd ask JCHD directly.

Greywater: No county-specific ordinance turned up. This likely falls under JCHD's general onsite wastewater permit authority, following the state Bureau for Public Health's design-standards framework, but that's an inference, not a confirmed county rule.

Rainwater harvesting: Nothing county-specific here either. This appears to inherit the state's general hands-off stance on non-potable rainwater collection.

Wells: State well-drilling certification rules apply. Where it gets county-specific is subdivision review: if you're dividing land not served by public sewer, JCHD requires a subdivision application, and there's a minimum lot size involved (I don't have the full confirmed figure, so ask JCHD).

Utilities: No standalone "must connect to the grid" rule found. But between the building code and the septic-before-building-permit sequence, you'll functionally need code-compliant construction and an approved wastewater plan even if you're off the electric grid entirely.

Bottom line: Jefferson County layers its own zoning, building code, and health department rules on top of the state baseline, so don't assume WV's "unzoned county" reputation applies here. Call ahead.
