Unincorporated Marshall County, West Virginia has no building or zoning department, and the county's own directory lists no countywide building-permit or zoning process12. Septic systems and private wells still need a permit from the Marshall County Health Department, the local authority the state assigns to review those applications34. West Virginia has no mandatory statewide building code5, and the county commission says the county has no jurisdiction over its incorporated towns, which can set their own building and zoning rules6.

Do you need a building permit in Marshall County, West Virginia?
Marshall County has no building or zoning department, and its official directory lists no countywide building-permit process for unincorporated land1. That fits the bigger picture: West Virginia has no mandatory statewide building code, and a code only applies where a county or municipality has specifically adopted one5. Marshall County's own building-code adoption isn't documented on its website, so the honest answer is that the county doesn't appear to have one, but you should still confirm with the County Commission before you build6. The state's Office of the State Fire Marshal, which enforces the State Fire Code on covered buildings, does not have jurisdiction over one- to two-family dwelling houses, so a typical home is outside its reach too12. Buildings used primarily for agricultural purposes are separately exempt from the State Building Code, the State Fire Code, and any county or municipal code, wherever those apply13.
Who do you contact for permits and land-use questions in Marshall County?
Every septic and well permit in Marshall County goes through the Marshall County Health Department's Environmental Division, at 304-845-7840, 513 6th Street, Moundsville, WV 2604114. There is no separate building, zoning or floodplain office listed for the county; the Marshall County Commission, at (304) 845-0482 or [email protected], is the general point of contact and can direct you to the right state or county office for anything the Health Department doesn't handle6. The commission's own page is explicit that it has no jurisdiction over the county's incorporated towns, so if your land is inside Benwood, Cameron, Glen Dale, McMechen or Moundsville, that town's own offices — not the county — set the rules6.
Does Marshall County have zoning?
No countywide zoning ordinance for Marshall County is identified on the county's official pages2. West Virginia law lets a county zone all or part of its jurisdiction if the county commission chooses to adopt an ordinance, but nothing on Marshall County's own site states that it has15. What is confirmed is that the county has no authority over its incorporated towns, so Benwood, Cameron, Glen Dale, McMechen and Moundsville can each set their own zoning and building rules independent of the county6. If you're buying unincorporated land outside those towns, don't assume the absence of county zoning means no restrictions ever apply — deed covenants, floodplain rules and state septic/well law still reach the property; a specific setback, lot-coverage or building-height question for unincorporated Marshall County isn't answered on the county's own pages, so it's worth a call to the Commission before you buy.
How do septic and well permits work in Marshall County?
Every new or modified septic system in Marshall County needs a permit before installation and a final inspection before it can be covered or used, administered through the Marshall County Health Department161718. This matters more here than in most places: only 0.5% of Marshall County's soils are free of severe limitations for a conventional septic drain field, so most sites need an engineered system and a careful site evaluation before you commit to a piece of land7. Wells work the same way — a permit from the same Health Department is required before a well is drilled, modified or abandoned, and the well must be drilled by a licensed driller4. Repairs that stay outside the drainfield, like clearing tree roots from a solid pipe, generally don't need a new permit, but any work inside the drainfield does, and stone-filled "absorption pit" repairs deeper than three feet are illegal statewide17.
Can you live in an RV or tiny home on your land in Marshall County?
Marshall County's official pages don't state a rule either way for long-term RV or tiny-home occupancy on private land — this is unconfirmed, not permission. The county's General Sanitation rule reaches organized campgrounds, fairs, mass gatherings and similar recreational facilities, but that's a rule for commercial and public recreation sites, not for a single owner living in an RV or tiny home on their own unincorporated tract19. If you're inside one of the county's incorporated towns, check that town's own rules, since the county has no authority there6. Outside the towns, call the Health Department about septic/well needs for the structure and the County Commission about anything else before you commit to the plan146.
Building a home in Marshall County: the steps, in order
- Call the Marshall County Commission to confirm there's no building or zoning requirement that applies to your specific parcel, especially if it's near or inside an incorporated town6.
- If the land is primarily agricultural, note that agricultural structures are exempt from the State Building Code, State Fire Code and any county or municipal code that would otherwise apply13.
- Apply to the Marshall County Health Department for a septic permit before installing any sewage system, and expect a site evaluation given how limited the county's soils are for conventional drain fields177.
- If you need a well, apply for a well permit through the same Health Department before drilling4.
- If the parcel touches a mapped floodplain, contact the County Commission to identify Marshall County's floodplain permit officer; the state requires every county to maintain a floodplain ordinance and permitting system206.
- If you're connecting a new driveway to a state highway, apply for a free driveway permit from your local West Virginia Division of Highways district office; Marshall County itself owns and repairs no roads216.
- If you plan to disturb one acre or more of ground, check whether you need a WVDEP construction stormwater permit22.
What to check before you buy land in Marshall County
Soils and septic: with only 0.5% of the county's soils free of severe septic limitations, budget for an engineered system and get a site evaluation before you buy, not after7. Terrain: only 12.2% of Marshall County is at 15% slope or gentler, and 75.8% of the county is wooded, so expect a steep, forested lot in most cases, which affects both septic siting and driveway cost2324. Flood risk: Marshall County is required to maintain a floodplain ordinance and permitting system, so confirm flood-zone status and the permit officer with the County Commission before you build near a stream206. Municipal boundaries: confirm whether the parcel sits inside Benwood, Cameron, Glen Dale, McMechen or Moundsville, since the county has no authority inside those towns and the rules will differ6. Setting and taxes: Marshall County has about 29,405 people at 96.3 people per square mile, is roughly 53 miles from the nearest metro area, and carries a 0.5% effective property tax rate with a $637 median tax bill2526271128.
Watch-outs
- Whether Marshall County has adopted any building code, and what applies outside its incorporated towns, is not stated on the county's own pages — confirm with the County Commission before you build6.
- The state's new right-to-ADU law only reaches West Virginia municipalities; it does not require unincorporated Marshall County to allow accessory dwelling units10.
- No official source names Marshall County's floodplain permit officer; call the County Commission to be directed to the right office before building near a stream or floodplain206.
