Unincorporated Kanawha County, West Virginia requires a building permit for most new construction, issued by the county Planning & Development Department.1 The county also has zoning countywide, administered by the same department.2 Septic systems are not permitted by the county at all; they go through the Kanawha-Charleston Health Department.3 Nearly all of the county's soils are rated severely limited for a conventional drain field, so plan on a full site evaluation before you count on a standard septic system.4

Do you need a building permit in Kanawha County, West Virginia?
Yes. Unincorporated Kanawha County requires a building permit for new construction and most other work, enforced by the county Planning & Development Department.1 The department describes its own role as one that "enforces land use ordinances in unincorporated areas of Kanawha County, overseeing building permits, zoning regulations, floodplain management, and property maintenance."8 Structures used primarily for agricultural purposes are excluded from the county's building and housing code authority, and from the State Building Code and State Fire Code, under state law.9 West Virginia's owner-builder exemption lets a property owner personally perform construction work without holding a contractor's license, but it does not waive the building permit, inspection or certificate-of-occupancy requirements that otherwise apply.6 The department's own ordinance list includes the State Building Code, confirming the county has adopted it for county-regulated construction.8
Who is the Kanawha County building department, and how do you reach them?
Kanawha County Planning & Development Department handles building permits, zoning and floodplain management for unincorporated Kanawha County.8 Reach the department at (304) 357-0570 or [email protected], or write to 407 Virginia Street East, 2nd Floor, Charleston, WV 25301.8 The office keeps standard weekday hours, posted as Monday through Friday, 8:00 AM to 5:00 PM.8 Building permit, board of appeals and subdivision applications are all listed on the department's page, so confirm which form your project needs before you apply.8
Does Kanawha County have zoning?
Yes, unincorporated Kanawha County has zoning administered countywide by the Planning & Development Department.2 West Virginia law lets a county zone its entire jurisdiction or only part of it, and lets the county set the district boundaries on a filed zoning map.10 Zoning district maps and boundary changes must be filed with the county clerk, so a title search or plat review should turn up your parcel's district before you buy.11 The county separately regulates mobile home parks as their own ordinance category, distinct from placing a single manufactured home or RV on a private, unincorporated lot.8 Our reviewed sources do not confirm a specific countywide rule for RV or tiny-home occupancy on an individual unincorporated lot, so confirm your parcel's zoning district and any occupancy limits with Planning & Development before you buy or move a unit onto the land.
How do septic permits work in Kanawha County?
Septic (on-site sewage) permits in Kanawha County are issued by the Kanawha-Charleston Health Department, not the county building department.3 The process starts with hiring a certified installer, who performs a percolation test and site evaluation; the homeowner or installer then files an application with the health department.12 The health department's own page states: "once an application, building permit, and fees are received, a sanitarian will contact the certified installer to schedule a visit to the site of the proposed new system, modification or repair," and a construction permit is issued only after the sanitarian approves the site.12 Soils matter here more than most counties: essentially none of Kanawha County's soils are rated free of severe limits for a conventional drain field, which in this county's steep terrain generally means engineered or alternative systems rather than a standard trench field.4 Only about 12% of the county's land sits at 15% slope or less, so expect the health department's site evaluation to drive both the system design and its cost.13
Can you live in an RV or tiny home on your land in Kanawha County?
Our reviewed sources do not confirm a countywide rule allowing or barring RV or tiny-home living on a private, unincorporated Kanawha County lot. Kanawha County zones the entire unincorporated county through its Planning & Development Department, and zoning ordinances commonly set occupancy and structure rules by district, so ask the department directly which district covers your parcel and what it allows before you buy or move a unit in.2 The county's mobile home park ordinance covers organized parks, not an individual manufactured home or RV placed on its own unincorporated lot, so it does not answer this question either.8 Do not assume RV or tiny-home living is unrestricted just because the county has no building-permit exemption for one; confirm in writing with Planning & Development.
Building a home in Kanawha County: the steps, in order
- Call Kanawha County Planning & Development to confirm your parcel's zoning district and what it allows before you design or buy.8
- Apply for and receive a county building permit before construction starts; applications are listed on the department's page.81
- If you need a well, apply for a well permit from the Kanawha-Charleston Health Department before a licensed driller begins work.5
- For septic, hire a certified installer for a site and percolation evaluation, then submit your application with the building permit and fees to the Kanawha-Charleston Health Department; a sanitarian must approve the site before a construction permit is issued.12
- If your parcel touches a mapped floodplain, contact Planning & Development's floodplain program before building, filling or altering a watercourse.148
- If your driveway will connect to a state highway, get the free encroachment/driveway permit from the WV Division of Highways district office before you build it.15
- If your project disturbs one acre or more, apply for a WVDEP construction stormwater permit through its Electronic Submittal System and file a Notice of Termination once the site is stabilized.16
- Schedule your final building inspection with Planning & Development, and for septic, call the health department for its final inspection before the system is covered.812
What to check before you buy land in Kanawha County
Confirm the parcel's zoning district with Planning & Development, since Kanawha County zones the entire unincorporated county and district rules can affect RVs, tiny homes, minimum home size and setbacks.2 Budget for a full septic site evaluation: almost none of the county's soils are rated free of severe limits for a conventional drain field, and only about 12% of the land is gentle enough (15% slope or less) to make siting easy.413 Ask Planning & Development whether the parcel sits in a mapped floodplain, since floodplain development in Kanawha County requires a permit and, in some flood zones, an engineering study showing no unacceptable rise in flood elevation.14 If the property fronts a state highway, plan for a free WV Division of Highways driveway permit before you build access.15 The county is 93.9% wooded and gets about 46.7 inches of precipitation a year, with severe drought in only about 2.2% of years, so plan a driveway and site layout around tree cover and wet-weather access.171819 Typical property tax in the county runs about a 0.7% effective rate, with a median bill near $922 a year; factor that and a typical homeowner's insurance premium near $1,127 a year into your budget.202122
Watch-outs
- Kanawha County's soils are almost entirely rated severely limited for a conventional septic drain field, so budget for a site evaluation and a likely engineered or alternative system rather than a standard trench field.4
- West Virginia's owner-builder exemption only waives contractor licensure; it does not waive Kanawha County's building permit, inspections or certificate-of-occupancy requirements.6
- No countywide rule confirms whether you can live in an RV or tiny home on an unincorporated Kanawha County lot; get a written answer from Planning & Development for your specific parcel before you buy or move one in.2
