Ohio County, West Virginia requires a Floodplain Building Permit for all construction or development anywhere in the county, whether the land is in a mapped flood hazard area or not1. That's a real countywide permit requirement even though the county has no general building code and no zoning ordinance of its own — zoning is handled only by the City of Wheeling, not the county2. Septic systems are separate again: every onsite sewage system needs a permit from the Wheeling-Ohio County Health Department3.

Do you need a building permit in Ohio County, West Virginia?
Yes, but it's not an ordinary building-code permit: Ohio County requires a Floodplain Building Permit for all construction or development anywhere in the county, whether the land sits inside a mapped Special Flood Hazard Area or not110. That's a real permit you must file before you build, even though the county has not been shown to have adopted a general building code of its own11. West Virginia law lets a county commission adopt building and housing codes by order, and separately lets a county require floodplain-related building permits countywide to comply with the National Flood Insurance Act, which is the specific authority behind Ohio County's program12. Inside the City of Wheeling, a second, more conventional layer applies: the city requires a building permit for any structural, electrical, plumbing, or building alteration, reviewed under its own building-code services13. Buildings used primarily for agricultural purposes are exempt from the State Building Code, State Fire Code, and any county or municipal code that might otherwise apply6.
Who handles building, floodplain, and septic permits in Ohio County?
The Floodplain Building Permit that applies to all construction countywide is issued by Ohio County Emergency Management, at 1500 Chapline Street, Lower Level, Wheeling, WV 26003, phone 304-234-375614. Septic and water-well permits go through the Wheeling-Ohio County Health Department, at 1500 Chapline Street, Wheeling, WV 26003, phone (304) 234-368215. If your land is inside the City of Wheeling, ordinary building, electrical, and plumbing permits are handled separately by the City's Building & Planning Department, also at 1500 Chapline Street, Wheeling, WV 26003, phone (304) 234-361716. All three offices sit in the same downtown Wheeling building, but they administer entirely different programs, so confirm which one applies to your specific project before you call.
Does Ohio County have zoning?
No countywide zoning ordinance was located for Ohio County; the county commission's own government page lists no planning or zoning department, and zoning here is administered at the municipal level instead2. The City of Wheeling is the clearest example: its zoning map divides the city into districts, with ordinances setting what's permitted in each and a Board of Zoning Appeals available for waivers, reductions, or variances4. West Virginia law does let a county commission adopt zoning covering all or part of its jurisdiction, so a countywide ordinance is a legal possibility, not just a Wheeling-only feature by default, but no official source confirms Ohio County has adopted one17. Because minimum dwelling size, minimum lot size, lot coverage, and building height rules in West Virginia typically flow through a local zoning or subdivision ordinance, and no such Ohio County ordinance was located for unincorporated land, treat those as unconfirmed rather than assumed absent, and check directly with the County Commission before you build18.
How do septic permits work in Ohio County?
Every onsite sewage system in Ohio County needs a permit from the Wheeling-Ohio County Health Department, which operates under West Virginia DHHR rule 64CSR473. If you're creating a subdivision that will use individual septic systems rather than public sewer, written health-department approval is required before any lot improvement, construction, or installation begins, and each dwelling needs its own 10,000-square-foot sewage-system reserve area that can never be built on7. Lot size changes the standard: lots under two acres must meet standard system requirements with at least three feet of suitable soil and a percolation rate between 5 and 90 minutes per inch, while lots two acres or larger can propose an alternative system if the percolation rate stays under 120 minutes per inch and soil-separation conditions are met7. Soils here make careful planning worthwhile: only 16% of Ohio County's land is free of severe limitations for a conventional drain field, so budget for a site evaluation and likely an alternative system on most parcels8. If you need a private well instead, the same Health Department issues the construction, modification, or abandonment permit required under West Virginia law before drilling begins1920.
Can you live in an RV or tiny home on your land in Ohio County?
No official Ohio County source located for this guide states a countywide rule for RV or tiny-home occupancy on private land, so treat this as an open question rather than an assumed yes or no. Because the county has no confirmed zoning ordinance outside Wheeling, there's also no confirmed county-level dimensional or occupancy rule to fall back on for unincorporated land2. If your parcel sits inside the City of Wheeling, its zoning ordinance and building-permit rules control what you can place and occupy there, and that's a different, more restrictive framework than unincorporated county land4. Wherever you are in the county, remember the Floodplain Building Permit applies to "all construction and or development in the county," which its own application form lists as covering manufactured homes and detached structures specifically, so a manufactured home or accessory building still needs that permit before placement21.
Building a home in Ohio County: the steps, in order
First, confirm whether your parcel is inside the City of Wheeling or unincorporated Ohio County, since building-permit and zoning rules differ sharply between the two4. Second, apply for the county's Floodplain Building Permit before construction begins, regardless of whether your land is in a mapped flood zone; check the fee schedule for your project's cost149. Third, if you need septic, get your site evaluated early; with only 16% of the county's soils free of severe limitations, plan on a careful design before applying8. Fourth, apply for your septic (and, if needed, water-well) permit through the Wheeling-Ohio County Health Department before installation15. Fifth, if you're inside Wheeling city limits, also apply for the city's building permit and schedule the required footer, framing, plumbing, electrical, and final inspections at least 24 hours in advance1622. Sixth, if your driveway will connect to a state highway, get the free encroachment permit from the WV Division of Highways District/County Permit Office before building the approach23. Finally, if you're subdividing land using individual septic systems, get written Health Department approval before development begins and record the required sewage-system reserve areas on your plat7.
What to check before you buy land in Ohio County
Septic soils are the headline constraint: only 16% of Ohio County's land is free of severe limitations for a conventional drain field, so budget for a site evaluation and likely an alternative system on most rural parcels8. Confirm whether the parcel is inside a mapped flood hazard area, since the countywide Floodplain Building Permit applies to every construction project either way, but the specific requirements and costs can differ inside the mapped zone24. Terrain here is hillier than much rural land: only 42.4% of the county sits at 15% slope or less, and 69.5% is forested, so grading and clearing costs deserve real budget2526. Confirm whether the tract is inside the City of Wheeling or unincorporated Ohio County, since zoning, building permits, and inspections differ sharply between the two2. Carrying costs are modest here: an effective property tax rate near 0.6%, a median annual bill around $970, against a typical home value of about $162,414272829.
Watch-outs
- "Ohio County" is in West Virginia, not the state of Ohio — Wheeling sits right on the Ohio River border, so double-check any search result or downloaded ordinance names Ohio County, West Virginia before relying on it2.
- Ohio County's Floodplain Building Permit applies to all construction countywide, in or out of a mapped flood zone — don't assume you're exempt just because your land isn't in the flood hazard area10.
- No official Ohio County source confirms or denies a countywide zoning ordinance, minimum lot size, setbacks, or RV/tiny-home occupancy rule for unincorporated land; these are open questions, not confirmed absences, so confirm with the County Commission2.
