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

Yes, for work covered by Ohio's building-permit requirement. Plans, drawings, specifications, and supporting data must be approved by the building department with jurisdiction before regulated construction begins.10 Greene County Building Regulation provides residential and commercial permit and inspection services for most of the county, but Fairborn, Xenia, Bowersville, Clifton, Cedarville, Yellow Springs, and state or federal properties are outside that office's stated service area.2 Greene County identifies the 2019 Residential Code of Ohio for one-, two-, and three-family dwellings and their accessory structures.11 Agricultural buildings may qualify for a conditional state-code exemption, but the applicable zoning inspector must issue the required agricultural-use zoning certificate; do not assume a barn is exempt merely because it sits on rural land.12 We could not confirm a Greene County owner-builder exemption, so ask the permitting office with jurisdiction before relying on one.6

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

The Greene County Department of Building Regulation is at 667 Dayton-Xenia Rd., Xenia, OH 45385, phone (937) 562-7420.2 Greene County accepts building submittals electronically and uses its iWorQ portal for permit applications, file uploads, and inspection scheduling; obtain applicable zoning approval before the building permit is issued.13 All applicable county building fees must be paid before plan review begins, fees become nonrefundable once processing starts, and an application unpaid for more than 60 calendar days is considered abandoned.14 Once plan approval is issued, the building official directs the necessary inspections.15 Commercial buyers should not confuse the county's limited existing-building certificate-of-occupancy process with approval for a change of occupancy, alteration, or addition; those projects do not qualify for that application.16

Does Greene County have zoning?

Yes, but Greene County zoning is administered through separate township, city, and village jurisdictions rather than one uniform county rule.3 All 12 townships and all municipalities except Bowersville have adopted zoning regulations, and questions go to the zoning inspector for the parcel's jurisdiction.1718 Before buying, identify the parcel's jurisdiction, then read its zoning map and resolution and ask its inspector about the proposed use. We could not confirm countywide numeric rules for setbacks, minimum lot size, dwelling size, building height, or lot coverage because those answers depend on the local zoning district. Greene County's directory also identifies some jurisdictions as outside county coverage, reinforcing that a permit or answer from one locality should not be carried over to another.3

How do septic permits work in Greene County?

Greene County Public Health's Environmental Health Division reviews or designs plans for private sewage systems on vacant lots, permits new installations or abandonments, and inspects installations.419 Private systems serve one-, two-, or three-family dwellings where connection to a sanitary sewer is not possible.20 Ohio requires a site review before the health board accepts an installation or alteration permit application, and the permit is valid for one year with a possible six-month extension.21 Greene County inspects every new sewage-system installation and inspects existing systems when requested or required.5 Ohio also requires a follow-up inspection no later than 12 months after installation approval.22 Because 0% of Greene County soils are rated free of severe limits for a conventional drain field, make the site evaluation an early contingency rather than assuming a standard trench field will fit.8

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

Reviewed sources do not confirm a single countywide answer, because it depends on your township's own zoning resolution.18 Since all 12 Greene County townships and nearly every municipality have adopted their own zoning, ask your specific township's zoning inspector whether RV or tiny-home occupancy is allowed on your parcel and under what conditions before you buy or move one in.17 Ohio's campground rules limit how many RVs can occupy a licensed campground site and require sites to meet minimum size and sanitation standards, but those rules govern licensed campgrounds, not what you can park or live in on your own land, so they don't answer this question.23 A manufactured home installed in Ohio generally cannot be occupied until the state inspector issues the inspection seal, on top of whatever your township's zoning requires for site placement.24

Building a home in Greene County: the steps, in order

  1. Identify the parcel's township, city, or village and obtain any required zoning approval from that jurisdiction.318
  2. Ask Greene County Public Health whether sanitary sewer is available; private septic systems are used where sewer connection is not possible.20
  3. If septic is needed, complete the site review and obtain the installation permit before work begins.421
  4. If a private well is planned, submit the applicable installation, alteration, or abandonment permit to Greene County Public Health.7
  5. Apply electronically to the building department with jurisdiction, upload the plans, pay all applicable fees, and wait for approval before construction.131410
  6. If the driveway is new or modified along a county road, obtain the County Engineer permit before construction.25
  7. Schedule building and septic inspections through the responsible offices.135

What to check before you buy land in Greene County

Confirm the parcel's township, city, or village and read that jurisdiction's zoning resolution and map before treating the land as buildable.3 Budget for septic due diligence: with 0% of county soils rated free of severe limits for a conventional drain field, a site evaluation should come before the final house plan.8 Ask Greene County Public Health about both sewer availability and private-water permitting.207 Verify road ownership as well: a new or modified driveway along a county road needs a County Engineer permit before construction, but that rule does not cover every road in Greene County.25 If the purchase involves a land split, ask the planning authority whether subdivision review applies. Ohio generally treats a division creating a parcel under 5 acres as a subdivision, subject to statutory exceptions.9 Property taxes have a typical effective rate near 1.7% and a median annual bill around $4,021.2627

Watch-outs

  • Zoning in Greene County comes from your own township or municipality, not the county; rules differ from one township to the next, so don't assume a neighboring township's setback or RV/tiny-home rule applies to your parcel.17
  • We could not confirm an owner-builder or owner-occupant permit exemption for Greene County; ask the building department with jurisdiction rather than assuming one applies.6
  • None of Greene County's soils are rated free of severe limits for a conventional septic drain field, so budget for a site evaluation and a possible engineered system rather than a standard trench field.8
