Mason County, West Virginia has no confirmed general residential building permit requirement for unincorporated homes1, but development in a designated floodplain requires a local floodplain permit2. Countywide zoning has not been confirmed3. Septic permits for new installations come from the Mason County Health Department, whatever a city does with its own building permits or zoning4.

Do you need a building permit in Mason County, West Virginia?
Mason County has no confirmed general residential building-code permit requirement for a home on unincorporated land1. The county nevertheless publishes a Development Permit Application that includes residential new construction, houses and mobile homes, and asks whether the site lies in an identified flood-hazard area5. Development inside a designated floodplain requires a county or community permit, and the local permit officer decides which mapped-zone standards apply214. West Virginia's State Building Code has force only in counties and municipalities that adopt it, with enforcement left to the local jurisdiction, and we could not confirm that Mason County has adopted it1516. Buildings used primarily for agricultural purposes are exempt from the State Building Code, the State Fire Code and any county or municipal building code that is or may be adopted, so a barn or farm structure would stay outside a Mason County code even if the county adopts one13. Floodplain, septic and other permits can still apply to those buildings17. Inside Point Pleasant, the city has adopted the State Building Code, so the city rather than the county is the place to ask about a building permit there18. Before designing a house outside a floodplain, ask Mason County Floodplain & Permits whether the Development Permit applies to the parcel19.
Who issues building permits in Mason County, and how do you reach them?
Mason County does not identify a separate residential building-inspection department, so the practical first contact is Floodplain & Permits through the Mason County Commission119. The commission is at 200 Sixth Street, Point Pleasant, WV 25550, and its main phone is 304-675-111019. The county's Division of Homeland Security and Emergency Management publishes the Development Permit Application for residential and non-residential projects5. The form covers new construction, repairs, alterations, fill and waterway work, and asks about mapped flood hazards5. For onsite sewage, contact the Mason County Health Department at 216 Fifth Street, Point Pleasant, WV 25550, phone (304) 675-305020.
Does Mason County have zoning?
We could not confirm a countywide zoning ordinance for unincorporated Mason County3. That is not the same as proof that every parcel is unrestricted: West Virginia counties may enact zoning for their entire jurisdiction or only part of it, while municipalities regulate land inside their own boundaries6. We also could not confirm countywide standards for setbacks, minimum dwelling size, building height, lot coverage or accessory dwellings on unincorporated land3. West Virginia's framework says that a locally adopted subdivision ordinance must contain lot-size and setback standards, but it supplies no single statewide numeric minimum21. Ask Floodplain & Permits about the parcel and ask the relevant municipality separately if the land is inside city limits196.
How do septic permits work in Mason County, West Virginia?
A written permit is required before installing a septic or other sewage-disposal system in Mason County, and the Mason County Health Department designs and evaluates new septic installations and issues the septic permit74. State law requires that written permit from the state commissioner or an authorized representative, which is the role the county health department fills locally22. The state On-Site Sewage program backs the county with rule interpretation and technical help on conventional and alternative systems8. Anyone who installs a septic tank must also register it and pay a $30 fee to the county health department where the tank is installed9. Only about 1.4% of Mason County soils are rated without severe limitations for a conventional drain field, so make septic feasibility an early purchase contingency23. Alternative systems may be considered for new construction only on lots of at least 2 acres24. A residential surface-discharge system of 600 gallons per day or less is permitted by the state on-site sewage program rather than the county, and must qualify for a WVDEP discharge permit258. Ask the health department about the site design and inspection stages before finalizing a plan20.
Can you live in an RV or tiny home on your land in Mason County?
We could not confirm a Mason County rule that allows, limits or prohibits long-term RV living, private-land camping or tiny-home occupancy on unincorporated land3. Private or off-grid sewage disposal is not automatically exempt from regulation: it needs written approval and must follow approved plans26. Inside Point Pleasant, an RV placed in a special flood hazard area must be on site for fewer than 180 consecutive days, remain licensed and highway-ready, or be installed under the city's manufactured-home placement and flood-reduction requirements10. That Point Pleasant rule does not establish permission elsewhere in Mason County10. The county's Development Permit Application includes a mobile home as a residential project type, but it does not settle RV or tiny-home occupancy5. Before buying, give Floodplain & Permits the parcel location and proposed use, then ask the Health Department whether the proposed sanitation system can be permitted1920.
Building a home in Mason County: the steps, in order
- Ask Floodplain & Permits whether the parcel needs a Development Permit and whether it is in a mapped floodplain192.
- If directed, submit the county application with the project type, construction details and flood-hazard information it requests5.
- Contact the Mason County Health Department for the septic site evaluation and installation permit420.
- Apply for a well permit at least 15 calendar days before drilling, altering or abandoning a private well; the driller and owner obtain it jointly, and the permit is valid for one year27. The well must be drilled by a licensed well driller28.
- Contact the utility-locate service before excavation; the county form says to do so 48 hours to ten days before digging starts5.
- If the driveway joins a state highway, obtain the free Division of Highways encroachment permit before construction29.
- Obtain state construction-stormwater coverage before disturbing one acre or more, including a smaller site within a larger common plan30.
- An owner may personally perform work without a contractor license, but that exemption does not cancel applicable permits or inspections11.
What should you check before buying land in Mason County?
Check septic feasibility and slope before closing: about 1.4% of county soils lack severe limitations for a conventional drain field, and about 27.8% of the land has a slope of 15% or less2331. About 71.8% of Mason County is wooded, so clearing and access can materially affect the buildable site32. Verify flood status with Floodplain & Permits because development in a designated floodplain needs local review and permit costs vary233. A driveway connecting to a state highway needs a free Division of Highways permit, and its location, design and construction must meet highway specifications29. The typical effective property-tax rate is about 0.5%, and the median annual property-tax bill is $6823435. The nearest city of 100,000 or more is about 100 miles from the county center, so price travel and contractor availability into the project36.
Watch-outs
- Mason County's application covers houses and asks about flood-hazard status, but we could not confirm whether the Development Permit is required for every new home outside a mapped floodplain; ask Floodplain & Permits before design work51.
- Structures on parcels used primarily for agriculture are exempt from the State Building Code and any county or municipal building code, and agricultural property is exempt from any county property-maintenance code, but those exemptions do not waive separately applicable septic, floodplain or highway-access permits121317.
- In Point Pleasant special flood hazard areas, RV placement is limited to fewer than 180 consecutive days unless the RV remains highway-ready or meets the city's manufactured-home placement and flood-reduction requirements10.
