Ashtabula County, Ohio requires a county building permit for any new structure over 200 square feet, which includes a home1. The county has never adopted countywide zoning apart from airport zoning, so townships and municipalities set zoning23. Septic approval comes from the Ashtabula County Health Department, and the Building Department wants it before it issues a permit for a new dwelling4.

Do you need a building permit in Ashtabula County, Ohio?
Yes. Ashtabula County requires a building permit for residential construction and alterations handled by its Building Department, including any new attached or detached structure over 200 square feet1. A one-story shed or playhouse at or under 200 square feet, a deck or porch under 30 inches above grade without a roof, and routine maintenance such as painting or re-roofing do not need one10. Footers and foundations for manufactured homes, mobile homes and industrialized units still need permits1. Agricultural buildings as defined by the Ohio Revised Code do not require a building permit when the owner submits a letter with a copy of the zoning certificate showing the use is agricultural8.
Who issues Ashtabula County building permits, and what do they cost?
The Ashtabula County Building Department takes building-permit applications at 25 W. Jefferson St. in Jefferson and can be reached at 440-576-373711. Before applying, have a formal address and parcel number, plus any zoning, plumbing and septic approvals that apply; a residential submission needs one paper plan copy and a PDF upload, and plan review can take up to 30 days12. Permits cannot issue until contractors are named and registered, required approvals are in and fees are paid12. The 2026 fee schedule lists a $250 base fee for a dwelling of 3,000 total square feet or less, plus a state 1% fee, a $75 non-refundable submittal and review fee and a $50 re-inspection fee5. A permit is valid for 2 years, construction must start within 12 months, and one free six-month extension is available if the office is notified before expiration5.
Does Ashtabula County have zoning?
Not countywide. Ashtabula County commissioners have never implemented countywide zoning, and airport zoning is the only one the county has2. Zoning sits with individual townships, and the county directs specific questions to the township zoning official13. Monroe, Richmond and Windsor townships have no township zoning resolutions13. Inside the cities of Ashtabula and Conneaut, the villages of North Kingsville and Orwell, and Geneva Township, the local body sets zoning1415161718. Setbacks, minimum lot size, accessory dwellings and minimum dwelling size therefore depend on the parcel's township or municipality, and we could not confirm a countywide answer to any of them3. Unlike most counties around it in Ohio, Ashtabula County has no county zoning19.
How do septic permits work in Ashtabula County?
For a new dwelling or an addition that adds living space, the Building Department requires Ashtabula County Health Department septic approval before it issues the building permit4. Ohio law requires the board of health to complete a site review before accepting a septic permit application, and the review includes a soil evaluation and a system design20. An approved installation permit is valid for 1 year and the board of health may extend it by six months20. The board must inspect the completed system again within 12 months of approval21. USDA rates 0% of the county's soils as not limited for a conventional drain field, so expect a site evaluation and possibly an engineered system rather than a standard leach field22. Call the Health Department at 440-576-6010 option 323.
Can you live in an RV or tiny home in Ashtabula County?
We could not confirm a countywide rule on long-term RV occupancy, camping on private land or tiny-home occupancy in Ashtabula County; ask the zoning office of the parcel's township, city or village3. Ohio's cited RV rules cover licensed and temporary campgrounds, not living in an RV on your own parcel24. A tiny home that is a new structure over 200 square feet still falls under the county building-permit rule1. A manufactured home generally cannot be occupied until the state inspector issues an inspection seal, and local site-placement rules may also apply25.
Building a home in Ashtabula County: the steps in order
- Find the parcel's township, city or village and get local zoning approval where it applies; the Building Department asks for a copy26.
- Contact the Ashtabula County Health Department for septic approval, which a new dwelling needs before the building permit issues4.
- Apply to the local board of health for a well permit before constructing or altering a private well, subject to Ohio's stated exceptions9.
- Get a formal address, confirm the parcel number and name your registered contractors, or use the owner-builder route with a signed waiver if you qualify126.
- Submit one paper plan copy and a PDF to the Building Department and allow up to 30 days for review12.
- Schedule each required inspection and get approval before the next phase; a final inspection comes before occupancy27.
What should you check before buying land in Ashtabula County?
Confirm the parcel's township or municipal zoning first, because the lack of countywide zoning does not settle use, setback or dwelling questions23. Order septic due diligence early, since USDA rates 0% of mapped county soils as not limited for a conventional drain field22. Ask the Health Department or an inspector about water: a private well needs a board-of-health permit9. Check flood status, because development in contact with a special flood hazard area needs a floodplain development permit before work begins28. A lot split of 5 acres or less in unincorporated Ashtabula County needs county Planning approval before transfer, plus review by township zoning and the sewerage authority29. We could not confirm one countywide driveway-permit process, so ask the county or township road authority.
Watch-outs
- Ashtabula County has no countywide zoning apart from airport zoning, but a township or municipality may still govern the proposed use23.
- A new dwelling needs health department septic approval before the Building Department issues the building permit, so start septic early4.
- Filling, grading or construction in contact with an identified special flood hazard area requires a floodplain development permit before work begins28.
- An eligible owner may act as general contractor or do the dwelling's own electrical, HVAC, hydronic or fire-suppression work, but must sign the county responsibility waiver67.
- Rules for RV living, private-land camping, minimum dwelling size, setbacks and accessory dwellings are unconfirmed countywide; ask the parcel's township, city or village zoning office3.

- Share of soils USDA rates "not limited" for a conventional septic drain field (SSURGO). A strict rating: the median county is about 6% and a tenth of counties are 0%, so a low figure means most lots need a site evaluation or an engineered system, not that septic is impossible.
