Do you need a building permit in Clermont County, Ohio?

Yes. The Clermont County Building Inspection Department is certified by the State of Ohio to regulate residential and commercial construction countywide, and a single-family home requires a permit1. Ohio law requires plans to be submitted to the certified building department before work begins12. A residential permit needs two sets of drawings with a cross-section and floor plans, and the county aims to finish residential plan review within 10 to 15 business days2.

Farm buildings are the main exception. Clermont County does not require a building permit for a structure on agriculturally zoned land that is not used mainly for retail or commercial purposes, once the department receives a zoning letter confirming the agricultural use2. Ohio's building code exempts buildings incident to agricultural use of the land that are not used in retail trade13.

No one may move in until the certificate of occupancy, or a conditional one, is issued2. We did not find an owner-builder rule on the county's pages; ask Permit Central whether you can pull your own trade permits14.

Who is the Clermont County building department, and how do you reach them?

The Clermont County building department is Permit Central, the Building Inspection Department at 2275 Bauer Road in Batavia, phone 513.732.7213, lobby open 8:00am to 4:00pm weekdays2. Applications and payments can also go through the county's online self-service portal2.

Permit Central is also where you apply for a driveway permit9. The County Engineer reviews and inspects driveways on county roads and on township roads in Batavia, Jackson, Monroe, Ohio, Pierce, Stonelick, Tate, Union and Williamsburg Townships, while Franklin, Goshen, Miami, Washington and Wayne Townships handle their own9. The driveway curb cut permit must be issued before a building permit is granted2. Ohio lets each certified building department set its own fee schedule, so ask Permit Central for current fees15.

Does Clermont County, Ohio have zoning?

Zoning approval in Clermont County is administered by the township or village where the parcel lies, and Permit Central needs a copy before it issues a permit72. The county's Planning Commission advises township zoning commissions and trustees rather than deciding local zoning cases16. The county keeps a list of township zoning offices and marks Washington Township as having no zoning3.

Ask the applicable township or village about RVs, tiny homes, minimum home size, lot size and setbacks because we could not confirm countywide standards for those questions. Ohio zoning law also limits regulation of agricultural uses17.

Land division is different: the Clermont County Planning Commission approves minor and major subdivisions under the county's Subdivision Regulations18. Before relying on an acreage-based exemption, ask Planning how the proposed split will be classified.

How do septic permits work in Clermont County?

Clermont County Public Health must review and approve a new-home septic system before construction84. The application includes the system design, formal soil report, surveyor's site plan, water-supply type, zoning permit, floor plan, parcel number and fee; a private-water application is also required when applying for septic4. Permit Central will not grant the building permit until Public Health issues the septic permit2. Call Public Health at (513) 732-749919.

Only 0.4% of Clermont County soils are free of severe limits for a conventional drain field, so establish a workable design before buying or siting the house11.

A septic system cannot be covered or used until the Health Commissioner inspects and approves it10. Systems with electrical components are then inspected every 19 months; all others are inspected every 38 months10.

Can you live in an RV or tiny home on your land in Clermont County?

We could not confirm a countywide rule allowing long-term RV occupancy or temporary camping on private land in Clermont County. Ask the parcel's township or village zoning office before relying on an RV as temporary or permanent housing; zoning approval is local, and Washington Township is listed as having no zoning73. Ohio's campground rules apply to licensed campgrounds, not to the separate question of living in an RV on your own lot20.

A tiny home built as a house needs a building permit like any single-family dwelling1. A manufactured home generally may not be occupied until the inspector issues its inspection seal21. Any dwelling using septic needs Public Health approval before construction4.

Building a home in Clermont County: what are the steps, in order?

  1. Ask Clermont County Planning to review any proposed lot split or subdivision18.
  2. Get zoning approval from the township or village where the parcel lies32.
  3. Choose the water and wastewater path. For septic, submit the design, soil report, site plan and private-water application together to Public Health45. If the property has sanitary sewer, obtain sewer and water permits from the Clermont County Sewer District6.
  4. Apply at Permit Central for the driveway permit; it must be issued before the building permit2.
  5. Submit the residential drawings and plot plan to Permit Central2.
  6. Complete the required inspections, including Public Health approval before covering or using a septic system10.
  7. Obtain a certificate of occupancy before moving in2.

What should you check before you buy land in Clermont County?

Start with wastewater: only 0.4% of Clermont County's soils rate well for a conventional drain field, so get a soil evaluation and designer input before closing11. If the parcel has sanitary sewer, the building-permit site plan must show the sewer line and connection elevation, and Sewer District water and sewer permits must come first6. For a home without public water, apply to Public Health for a private water system at the same time as septic5. Check local zoning and ask Planning to review any intended land division318.

Clermont County is about 19 miles from the nearest city of 100,000 or more and has about 468 people per square mile2223. The land is 55.9% wooded, and 80.3% has a slope of 15% or less2425. Farmland averages $7,599 an acre26. The effective property tax rate is about 1.3%, with a median bill of $3,141 a year2728.

Watch-outs

  • In Clermont County, the septic permit and the driveway permit both have to be issued before Permit Central grants a building permit2.
  • Only 0.4% of Clermont County's soils are free of severe limits for a conventional drain field, so budget for a mound or engineered septic system11.
  • A Clermont County septic system cannot be covered or used before approval, and recurring inspections occur every 19 or 38 months depending on its components10.
  • Zoning in Clermont County changes at the township line; Washington Township has no zoning while the other townships each have their own rules3.
  • Whether you can live in an RV or tiny home on your own Clermont County land is unconfirmed; ask the township zoning office before you buy3.
