Building permits, zoning and septic rules in Wood County, Ohio

Yes. Within Wood County Building Inspection's jurisdiction, building permits are required for covered new residential construction, additions and alterations, and work cannot begin until the permits are obtained¹. The county reviews one-, two- and three-family dwellings under the 2019 Residential Code of Ohio⁷. Submit the application, the calculated fee and two sets of drawings; approved drawings are stamped and signed, and one set must remain at the construction site⁷. Residential building fees start with a $75 base charge plus $0.20 per square foot of gross floor area, including the garage and basement but not crawl areas; a $50 occupancy or completion certificate applies, and a 1% state fee is added¹¹. A qualifying owner may personally perform electrical, plumbing or HVAC work without the state trade license if the owner occupies or will occupy the home, but building and trade permits still apply⁷. Like most counties around it in Ohio, Wood County requires a county building permit¹.

The Wood County Building Inspection Department handles covered residential building permits and the related electrical, plumbing and heating permits in unincorporated Wood County^1,7. Reach the department at One Courthouse Square, Bowling Green, OH 43402, by phone at 419-354-9190, or by email at buildinginspection@woodcountyohio.gov¹². Inside Rossford, the city's building and zoning inspector approves plans and issues building permits instead³. The permit holder or agent must arrange footing, foundation, structural, trade, rough and final inspections 48 to 72 hours in advance⁹. The certificate of occupancy is issued only after all required inspections are approved, and the building cannot be occupied before then⁹. Septic permits stay with the Wood County Health Department even inside city limits⁴.

Wood County does not zone unincorporated land itself: each township decides its own zoning, and the township keeps the final say¹³. Jackson and Montgomery townships are listed as unzoned, as is Bloomdale Village². Zoning is also local inside Rossford, Northwood, North Baltimore, Walbridge, Pemberville, Haskins and Grand Rapids^{14,15,16,17,18,19,20}. Obtain the local zoning permit before filing the building-permit application; the Building Inspection list of zoning boards shows who to call²¹. In an unzoned township, new subdivision lots need 2 acres and 175 feet of width where there is no central sewage²². Front setbacks from the right-of-way are 50 feet on arterial streets and 30 feet on collector or local streets, with 20-foot side and 30-foot rear setbacks²². Poor well or septic soils can lead the Planning Commission to enlarge lots or deny approval²².

The Wood County Health Department administers household sewage-treatment systems, including installation, alteration and operation permits, for every address in the county, city or not⁴. For new rural residential construction using septic, present the septic permit before securing construction permits; where sanitary sewer is available, present the sewer-tap approval instead⁶. Only about 0.1% of Wood County soils are rated without severe limits for a conventional drain field, so make the health department’s site and soils review an early purchase contingency⁸. The installer must notify the Health Department when the system is ready for final inspection; a further system inspection is required within 12 months, and NPDES and mechanical systems require annual inspection and sampling²³. A private realty sewage inspection is available on request, with a $400 inspection fee, and is not required by the state private-sewage rules; every septic system still needs an operational permit, which costs $150 in addition and is valid for five years depending on system type²⁴. For construction using an existing septic system or well, contact the Health Department about the Property Improvement Program and supply its permit number to Building Inspection if required¹.

We could not confirm a Wood County rule that generally allows residential use of an RV or tiny home on a private lot. Ohio's recreational-vehicle rules cited here govern campgrounds, not ordinary private parcels, so they do not answer whether you may live in a camper while building²⁵. Zoning rules vary by township and municipality, and specific classifications and permitted uses must be confirmed with the zoning authority for the parcel². Ask that authority specifically about RV occupancy, temporary camping, tiny homes and minimum dwelling size before buying or placing a unit. Septic approval remains a separate county Health Department question even where a township or municipality decides the land use⁵. A manufactured home has a separate statewide safeguard: occupancy generally must wait until the inspector issues the required inspection seal²⁶.

1. Identify the township, village or city, review its zoning map and resolution where published, and obtain the zoning permit from the local authority where one applies².
2. Obtain the septic permit from the Wood County Health Department or the sanitary-sewer approval needed for the site, and secure any required district water-tap permit^1,6.
3. For rural access, obtain the applicable Wood County Engineer driveway, curb-cut, private-drive-culvert or roadway permit; a township-road lot may also need local right-of-way approval⁶.
4. Ask the Wood County Planning Commission whether a floodplain development permit applies before designing in a Special Flood Hazard Area¹⁰.
5. Submit the building-permit application, calculated fee and two drawing sets to Building Inspection, then wait for the permit before starting work¹.
6. Schedule the required inspections, complete the finals and obtain the certificate of occupancy before moving in⁹.

Private water in Wood County falls under the Health Department’s permitting, inspection and enforcement program; a private-water-system form is required when supplying a building, small business or multiple dwellings²⁷. The program covers wells, springs, rainwater cisterns, hauled-water storage tanks and potable-water ponds, so an alternative water source still needs health review²⁷. Confirm the parcel’s township or municipality, zoning map and permitted use because local controls vary². Rural access work can require a Wood County Engineer driveway, curb-cut or culvert permit, with local right-of-way approval for township-road lots⁶. All land subdivisions in unincorporated Wood County, including parcel splits and minor subdivisions, are regulated by the Planning Commission; some municipalities may also have subdivision jurisdiction over nearby unincorporated territory²⁸. Ask the Planning Commission about its separate development permit for land in a Special Flood Hazard Area¹⁰. Wood County’s effective property-tax rate is about 1.4%, and its median annual property-tax bill is about $2,911⁸.
