We could not confirm a countywide residential building-permit requirement or zoning ordinance in Mingo County, West Virginia; both depend on local adoption12. Septic permits are a separate, confirmed step: the Mingo County Health Department issues a Construction Permit for a new, modified, or repaired on-site sewage system after site approval, and a well also needs a Health Department Construction Permit34. RV occupancy is confirmed at permitted public campgrounds, but the campground rules do not authorize residential RV living on private land5.

Do you need a building permit in Mingo County, West Virginia?
We could not confirm a countywide residential building-permit requirement in Mingo County. West Virginia has no statewide residential building-code requirement; local adoption and enforcement determine whether one applies, and no Mingo County adoption or inspection department could be confirmed1. County commissions may adopt building and housing codes by recorded order and have limited permit authority in mapped floodplain or mudslide areas, but those powers do not establish that Mingo County has exercised them1011. West Virginia exempts work personally performed by an owner or occupant on a structure from contractor licensure, but that exemption does not waive an otherwise applicable permit or inspection6. The State Fire Marshal's fire and life-safety inspections exclude one- and two-family dwellings, so they do not supply a house inspection either12. Buildings used primarily for agricultural purposes are separately exempt from the State Building Code, State Fire Code, and an adopted county or municipal building code13.
Who handles building, septic and county matters in Mingo County, and how do you reach them?
For current building, zoning, and floodplain contacts, call the Mingo County Commission at (304) 235-0380; its website is under construction and does not publish a department directory14. The Mingo County Health Department handles permits for new, modified, and repaired on-site sewage systems, with a Sanitarian approving the site before the department issues a Construction Permit3. Environmental Services is at 101 Logan Street, Suite 201 in Williamson and can be reached at (304) 235-357015. The Health Department also permits and inspects public campgrounds and manufactured-home communities1617. We could not confirm a specific county building department or floodplain administrator, so ask the County Commission who handles those functions before starting work1418.
Does Mingo County have zoning?
We could not confirm a countywide zoning ordinance for Mingo County. West Virginia counties may enact zoning for all or part of their jurisdiction, but no adopted Mingo County ordinance or zoning map could be confirmed219. Minimum lot size, setbacks, building height, lot coverage, accessory dwellings, and private-land RV or tiny-home occupancy therefore remain unresolved in unincorporated Mingo County; do not assume they are unrestricted. Campground and manufactured-home-community rules answer only those specific uses, not general parcel zoning1617. Incorporated municipalities may apply their own rules independently of the county, so ask the municipality directly when a parcel lies inside town limits.
How do septic permits work in Mingo County?
The Mingo County Health Department is the local authority for new, modified, and repaired on-site sewage systems, and a Sanitarian must approve the site before the department issues a Construction Permit3. A certified installer evaluates the site and submits an application; only after the permit is issued may construction or repair begin2021. If construction requires changing the approved plan, the installer must contact the Health Department before continuing, and a final inspection is required after the work is finished but before the system is covered22. Soils make this the hardest part of building here: none of Mingo County's mapped soils are free of severe limitations for a conventional drain field, so budget for an engineered or alternative system from the start7. A well needs its own Health Department Construction Permit: a certified well driller evaluates the site and files the application, a Sanitarian checks distances from sewage systems and buildings, and the listed fee is $125 per new or repair well4.
Can you live in an RV or tiny home on your land in Mingo County?
RV occupancy is allowed at a permitted Mingo County campground offered to the public for payment, including travel trailers, camping vans, motor homes, and pickup coach campers5. A covered campground has two or more camping units and must meet Health Department permitting, inspection, sanitation, campsite-size, and spacing rules5. Temporary camping is likewise confirmed only in permitted campgrounds and organized camps; the rule does not establish permission to camp on other private land23. We could not confirm whether long-term or residential RV occupancy or tiny-home occupancy is allowed on a private parcel outside those facilities, so ask the Mingo County Commission before relying on either use14. A community with four or more manufactured homes used as dwellings requires state and local health permits, detailed plans, and advance review, but that rule does not answer whether one manufactured home is allowed on an individual parcel17.
What are the steps to build a home in Mingo County?
- Call the Mingo County Commission at (304) 235-0380 to confirm building-permit, zoning, and floodplain requirements for the parcel because we could not confirm published county rules on those points14.
- Arrange a septic site evaluation early, since none of the county's mapped soils are free of severe limitations for a conventional drain field, and choose a certified installer to submit the sewage application720.
- Wait for the Sanitarian's site approval and Construction Permit before starting the septic work21.
- Hire a certified well driller to apply for the Mingo County Health Department well Construction Permit before drilling4.
- Obtain a free WV Division of Highways encroachment permit before building a driveway onto a state highway9.
- Have the Health Department inspect the finished septic system before it is covered22.
- An owner working personally on a structure is exempt from contractor licensure, but must still satisfy any applicable permit or inspection requirement24.
What should you check before buying land in Mingo County?
Confirm building-permit, zoning, and floodplain rules with the Mingo County Commission at (304) 235-0380 before buying because we could not confirm published county rules or a named floodplain administrator14. Septic feasibility deserves early attention: none of Mingo County's mapped soils are free of severe limitations for a conventional drain field, and only 6.1% of the land has a slope of 15% or less725. Every West Virginia county participates in the National Flood Insurance Program and has an ordinance regulating floodplain development, so check the flood map and identify the local permit officer before building near a stream18. Confirm legal access as well; a new driveway onto a state highway requires a free Division of Highways encroachment permit9. The effective property tax rate is about 0.4%, and the median annual property tax bill is about $3742627.
Watch-outs
- Mingo County's website is under construction, so call the County Commission at (304) 235-0380 to confirm unresolved building-permit, zoning, and floodplain procedures before assuming a rule or its absence14.
- None of Mingo County's mapped soils are free of severe limitations for a conventional septic drain field, so budget for an engineered or alternative system, not a standard gravity field7.
- West Virginia's owner-builder exemption only removes the contractor-licensure requirement for work you do yourself; it does not by itself waive any building permit, inspection, or certificate-of-occupancy requirement that might otherwise apply28.
