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

Yes. Champaign County Building Regulations requires a permit for a house, including modular and stick-built construction, and for listed work such as room additions, garages, carports and roofed porches.1 Certain detached buildings larger than 200 square feet also require permits, while the county cautions that its published list does not cover every situation.1 Ask Champaign County Building Regulations about the exact scope before work starts.

Permit approval is only part of the path to occupancy.13 Required residential inspections include foundation, framing, electrical, heating and final stages, while plumbing inspections are directed to the Health Department.14 A residence may not be occupied until the final inspection is approved.15

Construction must follow the Champaign County Building Code and the adopted Ohio Revised Code, Ohio Building Code and National Electrical Code editions.16

Who issues building permits in Champaign County, Ohio?

Champaign County Building Regulations is the county office identified in the published residential permit process.13 The process begins with zoning approval from the applicable city, township or village, followed by Health Department site-evaluation approval and any required driveway and house-number work.13 The building application then goes to Champaign County Building Regulations with the zoning permit, site approval and two sets of detailed plans.13

The county publishes residential and HVAC fee schedules, and charges vary with project valuation, trade and inspection type.17 Work started without a required permit may be charged twice the scheduled fee.17 Champaign County Building Regulations is at 1512 S. U.S. Hwy. 68, Bay 13, Urbana, OH 43078, phone 937-484-1602, and the department's hours are 8:00 AM to 4:00 PM Monday through Friday7. Septic and private-well questions go to the Champaign Health District at (937) 484-1605, not to the building office18.

Does Champaign County, Ohio have zoning?

Champaign County does not administer a countywide zoning ordinance.2 That does not make rural land unzoned: township zoning can apply in unincorporated territory, and city or village zoning can apply inside municipal boundaries.3 The county's own building-permit sequence tells applicants to obtain a zoning permit from the city, township or village before applying for the county building permit.13

Confirm the parcel's jurisdiction before relying on a listing description or planning a structure. Local zoning is where a buyer should ask about permitted uses, setbacks, minimum dwelling size, lot coverage, building height, accessory dwellings, RV occupancy and tiny-home occupancy.3 The county has no countywide minimum lot size; township zoning may set one, so ask the township zoning inspector.19 The correct answer for setbacks and dwelling size likewise depends on the parcel's township or municipality.

How do septic permits work in Champaign County?

The Champaign Health District permits and inspects new household sewage treatment systems in Champaign County, including private residential systems where sanitary sewer is not accessible.410 Ohio requires a site review before a sewage-system permit application is accepted; that review generally includes a soil evaluation and system design.20 The Health District lists a $249 fee for a new sewage permit, $224 for a replacement permit and $115 for an alteration or replacement permit, and site evaluation approvals are good for 3 years.21 Contact the Champaign Health District at (937) 484-1605 before committing to a house location or system layout.18

Soil deserves early attention: 0% of mapped county soils are rated free of severe limits for a conventional septic drain field.12 That rating does not by itself prohibit septic, but it makes the site evaluation and an appropriate design central to the budget. The building-permit sequence calls for Health Department site-evaluation approval before the building application.13

Can you live in an RV or tiny home in Champaign County?

A countywide answer for living in an RV on private land or occupying a tiny home could not be confirmed. Champaign County has no countywide zoning, but township and municipal zoning varies and may control residential uses on a particular parcel.23 Ask the zoning inspector for the parcel's township, city or village whether the proposed unit is a permitted dwelling, whether temporary occupancy is allowed during construction, and what setbacks or minimum-size standards apply.

A tiny home used as a residence does not escape the county's general permit rule merely because it is small: houses and listed residential construction require permits in the Building Regulations office's jurisdiction.1 For an RV, campground rules do not answer whether full-time occupancy is allowed on private land, so obtain a parcel-specific zoning answer before purchase.

Building a home in Champaign County: what are the steps?

Follow the county's published sequence and resolve the site constraints before ordering plans.

  1. Identify the parcel's city, township or village and obtain any required zoning permit.13
  2. Obtain Champaign Health District site-evaluation approval, then arrange the sewage-disposal, plumbing and private-well permits that apply.135
  3. For property on a county or township road, obtain the driveway permit and house number from County Engineering; contact ODOT for a state-highway parcel.22
  4. Submit the completed building application, zoning permit, site approval and two sets of detailed plans to Champaign County Building Regulations.13
  5. Pay the required fees, receive and post the permit, then schedule required inspections.1314
  6. Do not occupy the residence until the final inspection is approved.15

What should you check before buying land in Champaign County?

Start with jurisdiction: identify the township or municipality and get written answers on the intended dwelling, RV use, setbacks and lot standards because Champaign County has no countywide zoning.23 The Health District recommends contacting it before buying undeveloped property to confirm the parcel has been approved for septic use.23 Next, make the purchase contingent on a satisfactory septic site review; none of the county's mapped soils are rated free of severe limits for a conventional drain field.12

Confirm road authority and driveway access because County Engineering handles driveway permits and house numbers on county or township roads, while ODOT handles state highways.22 Check the flood map before placing a home or septic system because development in mapped special flood-hazard areas requires a permit and carries added construction standards.24 If the parcel needs a well, the Champaign Health District requires a permit for a new private water system or alteration of an existing one.5

Watch-outs

  • No countywide zoning does not mean no zoning; township, city or village rules may control the parcel.23
  • Do not start permit-required work early, because the county may charge twice the scheduled fee for work begun without the required permit.17
  • A home cannot be occupied until the final residential inspection is approved.15
  • Private-land RV occupancy, tiny-home occupancy and countywide minimum dwelling size remain unconfirmed; ask the parcel's township or municipal zoning office.3
