Unincorporated Hocking County, Ohio has no county residential building permit, but a new or replacement home outside Logan and licensed manufactured-home parks needs a Health Department Building Placement Permit before work begins12. Inside Logan, the city issues its own building permits and sets its own zoning34. Septic permits come from the Hocking County Health Department5.

Do you need a building permit in Hocking County, Ohio?
An ordinary home in unincorporated Hocking County does not require a county residential-code building permit because the county has no certified residential building department1. Ohio's residential building code supplies uniform requirements wherever a certified building department has jurisdiction, but we could not confirm a certified Hocking County department or separate county residential code for unincorporated land17. The Hocking County Health Department still requires its Building Placement Permit before construction starts on a new or replacement home outside Logan City and licensed manufactured-home parks2. A dwelling or other structure intended to have plumbing, sinks or drains also needs approved plans before construction, alteration or placement14. Manufactured homes and commercial buildings, including transient or cabin rentals, need a building permit through the Ohio Department of Commerce18. An agricultural building can qualify for a state building-code exemption when the applicable county or township zoning inspector issues a certificate declaring that specific structure will be used in agriculture19. Inside Logan, the city's own rules apply instead: new buildings and alterations need a zoning permit, and the zoning inspector may require a separate building permit3.
Who issues building permits in Hocking County, and who handles zoning, septic and floodplain?
The Hocking County Health Department issues Building Placement Permits for residential homes outside Logan City and outside licensed manufactured-home parks, at 740-385-3030 or 350 St Rt 664N, Logan, OH 4313820. The 2026 fee for a residential Building Placement Permit is $5521. The county's rules here apply to unincorporated land; inside Logan, the city's own offices issue building and zoning permits, while septic and wells stay with the Hocking County Health Department22${PB}. Manufactured homes and commercial buildings, including transient or cabin rentals, go through the Industrial Compliance Division of the Ohio Department of Commerce for building permits18. Hocking County Regional Planning, at 93 West Hunter Street, Logan, Ohio 43138 and (740) 380-9634, reviews land splits and administers the county's floodplain regulations; it does not issue building permits or septic permits237. New construction and remodeling in the county require Health Department plan review and permits for plumbing, onsite waste disposal and water systems, while Regional Planning supplies the floodplain determination2425. Driveway permits come from the County Engineer on county roads13. A published county planning fee schedule lists a $100 minor-subdivision lot-split fee and a $25 driveway permit fee, and other agencies may charge separately26.
Does Hocking County have zoning, and does Logan?
The City of Logan adopts and administers its own zoning code, run by the city zoning inspector, planning commission and board of zoning appeals4. Its districts include single-family residential, multi-family residential, manufactured home park, business and manufacturing27. Logan's zoning covers land inside its corporation limits only28. Zoning can be adopted only by township or municipal officials or by a vote of citizens, so rules outside Logan depend on the township6. We could not confirm whether a countywide zoning ordinance has taken effect, so ask Regional Planning which rules apply before treating rural land as unzoned24. County subdivision review is separate from zoning7. Most new minor splits must contain at least 80,000 square feet, or 1.836 acres, and must meet health, frontage, shape, floodplain, survey and engineer requirements; an abutting-landowner transfer is an exception to the minimum11. We could not confirm a minimum dwelling size, setback, lot-coverage limit or building-height limit for land outside Logan, so ask Regional Planning to check the parcel and applicable local jurisdiction24.
Who issues septic permits in Hocking County, and how do they work?
The Hocking County Health Department, not Regional Planning or the city, permits household and small-flow sewage systems serving a dwelling or building that produces less than 1,000 gallons of waste per day5. A site evaluation is required before home placement or construction, and the approved review remains valid for five years29. The Health Department must inspect the finished system before it is covered, and the home or building cannot be occupied until the system is approved9. The department inspects again one year after installation, while the operation permit must be renewed after ten years9. Only 7.5% of county soils are rated without severe limitations for a conventional drain field, so make the site evaluation an early purchase contingency rather than assuming a standard system will work16. The 2026 fee for a new or replacement system is $588 plus a $74 state fee, $662 in total21. Where sewer service is unavailable, a privy may be permitted only under limited conditions; the permit carries a $50 local fee plus a $74 state fee15.
Can you live in an RV or tiny home on your land in Hocking County?
We could not confirm a general Hocking County rule allowing or prohibiting long-term RV or tiny-home occupancy on private rural land. Ohio expressly allows human habitation in an RV for the period covered by a licensed campground's license, but that rule does not answer whether you may live in an RV on an ordinary private parcel30. A tiny home or other dwelling intended to have plumbing, sinks or drains falls within the Health Department's Building Placement Permit language14. Hocking County permits privies only under limited conditions, so the listed privy permit is not blanket approval for every off-grid parcel or sanitation method15. A used or relocated manufactured home installed as a residence must comply with Ohio's manufactured-home installation standards, and manufactured homes in the county areas covered by the Health Department page need a building permit through the Ohio Department of Commerce3118.
Building a home in Hocking County: the steps, in order
- Identify the parcel's township or municipality and confirm the applicable zoning authority; Logan zoning applies within the city limits, while zoning outside Logan remains unconfirmed3224.
- If the tract is being split, take the proposal to Regional Planning for subdivision, health, access and deed-processing review733.
- Obtain the required floodplain determination from Regional Planning25.
- Secure road-frontage or driveway approval from the township trustees, County Engineer or ODOT, depending on who maintains the road12.
- Have the Health Department evaluate the site, then obtain septic and private-water permits where those systems are needed2934.
- Obtain the Health Department Building Placement Permit before starting a new or replacement home outside Logan City and licensed manufactured-home parks2.
- Have the sewage system inspected before covering it, and complete the final water and plumbing inspections before occupancy935. Projects governed by the Ohio Building Code also need a certificate of occupancy before use, while manufactured-home and commercial projects covered by the county page need their building permit through the Ohio Department of Commerce3618.
What to check before you buy land in Hocking County
Start with wastewater feasibility: only 7.5% of Hocking County soils are rated without severe limits for a conventional drain field16. Then check terrain and clearing costs, because 37.4% of the county is at a slope of 15% or less and 84.8% is wooded3738. Ask Regional Planning for a floodplain determination and verify that any recent split passed the county's subdivision process257. Confirm legal, usable access with the authority that maintains the road; new splits typically require at least 100 feet of frontage with a usable driveway location12. Confirm whether public sewer is actually available before assuming you can avoid septic, because Sewer District connections require approval and a tap fee39. For a short-term rental, county lodging-tax registration and tax rules do not themselves establish land-use approval40.
Watch-outs
- We could not confirm a minimum dwelling size, setbacks, lot coverage or building height for land outside Logan City; ask Regional Planning to check the parcel before design begins24.
- We could not confirm long-term RV or tiny-home occupancy rules for an ordinary private parcel; a privy is available only under limited permit conditions and does not establish that the dwelling itself is allowed15.
