Do you need a building permit in Preston County, West Virginia?
A general county building permit is not required for a home in unincorporated Preston County1. Preston County has no county zoning, while building permits and zoning approval for construction inside an incorporated area come from that town's city hall3. West Virginia's State Building Code applies only where a county or municipality adopts it rather than automatically statewide16. Buildings used primarily for agriculture are exempt from the State Building Code, State Fire Code and adopted county or municipal building codes, though stricter compatible laws or agency rules may still govern17. Separate approvals still apply: septic installation, water-well work and development in a designated floodplain each require permits181019. We could not confirm a general residential inspection or certificate-of-occupancy process for unincorporated land, so ask the County Commission about those items and the parcel's floodplain status.
Who issues building permits, zoning approval and floodplain permits in Preston County?
Preston County does not publish a dedicated county building or zoning department; the county has no zoning, and a general permit is not required for unincorporated residential construction13. Start with the Preston County Commission for parcel-boundary, county land-use and floodplain-office questions20. The local permit officer reviews proposed work in a designated floodplain, determines the standards that apply and requires copies of other federal or state permits before issuing the floodplain permit; the fee varies2122. Inside an incorporated area, the town's city hall handles building permits and zoning approval, but septic and well permits do not move to the town318. The Preston County Health Department handles local septic application review and site inspections under the statewide public-health program, as well as individual-well permits2395. Road-repair questions go to the WV Division of Highways county office at 304-329-0192, not the County Commission24.
Does Preston County have zoning?
No. Unincorporated Preston County has no county zoning districts; anyone seeking a building permit or zoning approval inside an incorporated area must contact that town's city hall8. Unincorporated land therefore has no county zoning-based setback, lot-coverage or building-height rule252627. Unincorporated land also has no county zoning-based minimum dwelling size or minimum lot size1415. Those answers are limited to zoning: septic design, floodplain standards, subdivision review, deed restrictions and other non-zoning constraints can still determine where and what you may build. We could not confirm an unincorporated subdivision ordinance, so ask the County Commission about a recent or proposed land split. Municipal requirements are separate; Kingwood, for example, has a zoning appeals process, showing why a parcel inside town limits needs a city-hall check28.
How do septic and well permits work in Preston County?
A new or modified septic tank system in Preston County needs a permit before installation, after review of its application, plans and specifications29. Minor repairs outside the drainfield may be exempt, but work within the drainfield generally needs a permit18. West Virginia Public Health Sanitation has primacy over individual on-site sewage systems, while local health departments perform application review and site inspections3023. Do not cover a soil-absorption system or use the system until the director approves the installation in writing; covered work may have to be uncovered31. Only 2% of Preston County soils are rated without severe limitations for a conventional drain field, so make septic feasibility an early purchase contingency rather than assuming a standard system will fit32. A water well also needs a local-health-department permit before drilling, alteration or abandonment and must be drilled by a licensed driller5.
Can you live in an RV or tiny home on your land in Preston County?
Unincorporated Preston County has no county zoning restriction on residential or long-term RV occupancy11. Unincorporated Preston County likewise has no county zoning restriction on tiny-home occupancy12. Those answers are limited to county zoning, not blanket exemptions: septic permitting and inspection still apply to an on-site sewage system, and development in a designated floodplain needs separate approval183319. Private deed restrictions may also bind a parcel. A parcel inside an incorporated town needs a separate city-hall check because municipal rules may apply3. Before relying on an RV or tiny home full-time, confirm the sanitation plan with the Preston County Health Department9.
How do you build a home in Preston County, step by step?
- Confirm whether the parcel is inside an incorporated town; town building permits and zoning approval come from that city hall, while septic and well permits still come from the Health Department3.
- Ask the County Commission whether the building site is in a designated floodplain; floodplain development needs a permit even though unincorporated Preston County has no general residential building permit19120.
- Make septic feasibility a purchase contingency and apply through the Preston County Health Department before installation189.
- If the home needs a well, apply before a licensed driller begins34.
- If the driveway connects to a state highway, get the required WV Division of Highways encroachment permit; the permit is free of charge3536.
- If you will personally perform the work on property you own or lease, the owner-builder exemption removes contractor-licensing requirements but does not settle separate permit or code obligations13.
What should you check before buying land in Preston County?
Soils and septic go together here: with only 2% of the county's soils free of severe limitations for a conventional drain field, get a site evaluation from the Health Department before you commit to a purchase32. Water is generally plentiful, with about 51.5 inches of precipitation a year and severe drought in only about 1.9% of years, but a private well still needs a permit if there is no public supply37385. Terrain is mixed: 53.3% of the county sits at 15% slope or less, and 78.9% of the land is wooded, so expect real grading and clearing costs on steeper, more forested parcels3940. Ask the County Commission whether the building site is inside a mapped floodplain20. A floodplain permit is documented for the Route 7 waterline-extension portions crossing the 100-year floodplain of Dillan Creek, but that project-specific fact does not establish the rule for another parcel41. If the tract was recently split, ask the Commission whether a subdivision or plat process applies because we could not confirm a Preston County subdivision ordinance. Property taxes have an effective rate near 0.5% and a median bill around $747 a year4243.
Watch-outs
- A general building permit appears not to be required in unincorporated Preston County, but the County Commission's FAQ expressly confirms only that the county has no zoning; ask the Commission about inspections or occupancy paperwork1320.
- County zoning does not restrict RV or tiny-home occupancy on unincorporated land, but septic, floodplain, deed and municipal rules remain separate1112.
- Development in a designated floodplain needs a permit, but Preston County's public page does not name the administering officer; ask the County Commission where to submit before you build1920.

- Share of soils USDA rates "not limited" for a conventional septic drain field (SSURGO). A strict rating: the median county is about 6% and a tenth of counties are 0%, so a low figure means most lots need a site evaluation or an engineered system, not that septic is impossible.
