Do you need a building permit in Logan County, Ohio?
Yes. Logan County requires a building permit to construct, enlarge, repair, improve, alter, extend or move a home or other structure, as well as for listed building-system work1. Listed exemptions include general maintenance, certain roof repairs, qualifying small sheds and decks, interior finish work, sidewalks and driveways7. Ohio's residential rules are uniform where a certified building department enforces the state residential building code8. Before issuing the building permit, the Building Authority requires zoning, health-department and floodplain approvals; work around Indian Lake also needs sanitary-sewer review9. Covered construction receives staged inspections, with the final structural inspection before occupancy10. At completion, obtain a certificate of occupancy from the Building Authority and a zoning certificate from the township zoning inspector11.
Who is the Logan County building department, and how do you reach it?
The Logan County Building Authority is at 1365 County Road 32 N, Suite 2, Bellefontaine, Ohio 43311; phone 937-592-747312. The office handles residential and commercial building permits, plan review and inspections12. Schedule inspections by telephone at least 24 hours in advance10. The permit path also involves the applicable township or municipal zoning officer, the Logan County Health District and the floodplain administrator because their approvals precede the building permit2. Parcel splits in unincorporated Logan County require approval through the County Engineer's office, and lot-split review can also involve the Logan-Union-Champaign Regional Planning Commission, an engineer or a village13. Permit charges follow the certified department's locally adopted fee schedule, so ask the Building Authority for the current amount for the proposed work14.
Does Logan County have zoning?
Local zoning applies in Logan County except in Bloomfield Township and some areas of Stokes Township3. Where zoning applies, the municipality or township serving the parcel provides the zoning approval required for the building-permit application31. Minimum lot area and road frontage vary by local zoning district15. Setbacks, allowable building height and lot coverage are also district-specific, so obtain the current standards from the local zoning officer before choosing a homesite161718. We could not confirm a countywide minimum dwelling size; ask the same zoning officer about the proposed home type and use. Agricultural buildings can qualify for a conditional state-code exemption, but the use and zoning-certificate requirements must be satisfied19.
How do septic and well permits work in Logan County?
The Logan County Health District handles permits and inspections for covered household and small-flow onsite sewage systems20. A new or altered system requires an installation or alteration permit, a system design and a soil evaluation no more than five years old4. The Health District conducts a site-review inspection, a final inspection before the system is covered and another inspection within 12 months after approval21. Site conditions deserve early attention because 0% of mapped county soils are rated free of severe limits for a conventional septic drain field22. Where county sewer serves the property, the Water Pollution Control District handles sewer-tap and line-work approvals; cities and villages handle connections inside their limits23. A private well requires Health District approval, a scaled site plan, required separation distances and a permit fee5.
Can you live in an RV or tiny home on your land in Logan County?
We could not confirm a countywide Logan County rule allowing or prohibiting full-time RV occupancy, temporary camping or tiny-home occupancy on private land. Ask the township or municipal zoning authority serving the parcel about the proposed use, minimum dwelling size and temporary occupancy during construction. The answer can vary because local zoning applies in most of Logan County, while Bloomfield Township and some areas of Stokes Township are exceptions3. Even where the use is allowed, locally controlled lot size, setbacks, height and lot coverage can shape what fits on the parcel15161718. Ohio's campground rules address licensed campgrounds, not the general question of living in an RV on private acreage24. We also could not confirm an owner-builder exemption, so ask the Building Authority before doing regulated work yourself6.
Building a home in Logan County: the steps, in order
Identify the township or municipality, confirm the zoning district and obtain local zoning approval where required3.
Arrange sewage approval through the Logan County Health District or the responsible sewer authority, and apply for a private-well permit if needed4235.
Obtain a driveway permit from the County Engineer or ODOT when applicable; a state-highway driveway goes through ODOT before the County Engineer establishes the address25.
Obtain the floodplain determination required for every building application and any additional approval needed for construction or fill in a Special Flood Hazard Area26.
Submit the prerequisite approvals and plans to the Logan County Building Authority before construction2.
Schedule staged inspections by telephone at least 24 hours ahead10.
Complete the final inspection and obtain the certificate of occupancy and applicable zoning certificate before occupancy11.
What should you check before buying land in Logan County?
First verify the township or municipality because zoning exceptions and district standards can change what and where you may build31516. Order septic due diligence early because 0% of mapped soils are rated free of severe limits for a conventional drain field, and covered systems need a recent soil evaluation224. Confirm public-sewer availability or the private-well permit path before budgeting utilities235. Verify legal driveway access because a new homesite may need a County Engineer or ODOT permit25. Obtain the floodplain determination before fixing the homesite; construction or fill in a Special Flood Hazard Area needs additional approval26. For carrying costs, Logan County's effective property-tax rate is about 1%, and the median annual property-tax bill is about $1,9472728.
Watch-outs
Zoning is not uniform across Logan County: local zoning applies except in Bloomfield Township and some areas of Stokes Township, so confirm the parcel's exact jurisdiction before relying on a township rule3.
A building permit is not the first approval: zoning, health-department and floodplain signoffs must come first, and work around Indian Lake also needs a sanitary-sewer review2.
No owner-builder exemption was confirmed on Logan County's official permit materials; ask the Building Authority before assuming that doing the work yourself changes the permit requirements6.

county zoning authorityGeneral
County commissioners may adopt zoning resolutions regulating building, structures, land uses, and districts or zones in unincorporated territory statewide.
The authority is exercised by resolution and must be in accordance with a comprehensive plan.
The authority applies to unincorporated territory of the county.
The statute begins with the exception phrase “Except as otherwise provided in this section,” so the limitations in ORC Chapter 303 apply.
For nonresidential property only, the county may regulate height, bulk, number of stories, size, lot coverage, yards, courts, open spaces, and population density.
Agricultural uses and agricultural buildings are subject to the limitations in ORC 303.21; the statute also contains limitations for public utilities, railroads, telecommunications towers, alcoholic-beverage sales, oil and gas drilling, and permanently sited manufactured homes.
Activities regulated under ORC Chapters 1513 and 1514 may be regulated only in the interest of public health or safety, and Chapter 1514 activities must be provided for as permitted or conditional uses as specified by ORC 303.02.
“the board of county commissioners may regulate by resolution, in accordance with a comprehensive plan”
county building authorityGeneral
County commissioners may adopt and enforce local residential building regulations in unincorporated areas and may operate certified county building departments that enforce state residential and nonresidential building codes, accept and approve plans, and conduct inspections.
Local residential building regulations may be enforced within the unincorporated area or within districts established in the unincorporated area.
A local residential building regulation may not differ from the state residential building code unless it addresses subject matter not addressed by that code or is adopted under ORC 3781.01.
An existing structures code must concern subject matter not addressed by, and may not conflict with, the state residential building code.
County building departments may enforce state codes only for the types of buildings and subject matters for which they are certified.
Certification permits enforcement authority, plan approval, and inspections; the certification application identifies whether it covers residential or nonresidential buildings and whether residential certification covers new construction only or also repair and alteration.
The board may adopt flood-hazard, Lake Erie coastal-erosion, and drainage regulations, subject to the statutory limits and exceptions in ORC 307.37.
Local regulations, codes, or amendments require public hearings at not fewer than two regular or special board sessions; they take effect on the thirty-first day after adoption.
Regulations adopted under ORC 307.37 generally do not affect buildings or structures existing, or under construction, before adoption, except as provided for an existing structures code.
The state residential building code is effective as a uniform requirement in areas with a building department certified to enforce it.
“The board of county commissioners may adopt local residential building regulations governing residential buildings as defined in section 3781.06 of the Revised Code”
