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

Yes. Building permits are required for covered work in unincorporated Clark County and in the listed cities and villages, although repairs and certain replacements may not need one1. Clark County lists the 2019 Residential Code of Ohio, based on the 2018 International Residential Code, for residential construction under its jurisdiction6. Submit plans, drawings and specifications before construction; work cannot begin until the building department with jurisdiction approves them910. Plan approval generally expires if work does not start within 12 months, though one 12-month extension may be available for a fee of up to $10010. A certificate of occupancy follows final inspection for projects that require one, after the listed septic, safe-water, blower-door and any applicable elevation documents are submitted11.

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

Clark County's Building Department handles permits for unincorporated Clark County from Community & Economic Development at 3130 East Main Street, Springfield, Ohio 4550312. The county's online process lets applicants apply for building and zoning permits, check status, pay fees, and review inspection activity and results13. Contractors need an access code and can call (937) 521-2160 for help12. The county will not issue a permit until all required submittals arrive and fees are paid1312. Ohio lets each certified local building department set its own fee schedule, while Clark County's reviewed page confirms payment is required but does not provide a general building-fee schedule1415.

Does Clark County have zoning?

Yes, but zoning administration varies by location in Clark County3. Clark County Planning & Zoning handles Bethel, Green, Harmony, Mad River, Madison, Moorefield and Pleasant Townships2. German, Pike and Springfield Townships have separate township contacts, while Springfield, New Carlisle and the listed villages use their own contacts16. Use the county's jurisdiction information and Auditor GIS zoning maps to identify the authority and district for a parcel before relying on setbacks or permitted uses17. We could not confirm one countywide rule for minimum dwelling size, minimum lot size, setbacks, lot coverage, building height, accessory dwellings or agricultural exemptions. Ask the zoning authority for the parcel about each of those points before designing a home or outbuilding3.

How do septic permits work in Clark County?

The Clark County Combined Health District administers household septic systems and requires permits for installation, alteration and operation45. Before accepting an installation application, Ohio rules generally require a site review with a fee, soil evaluation and system design; an installation or alteration permit is valid for one year and may receive a six-month extension18. Clark County publishes a $50 site-approval fee15. New, replacement and altered systems receive installation inspection and another operating check no later than 12 months after approval19. Real-estate or refinancing inspections are different: the health district performs those on request, and no law requires a local-health-district inspection merely to sell a house20. Only about 14% of mapped Clark County soils avoid a “very limited” rating for a conventional drain field, so make site suitability an early contingency21.

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

We could not confirm a countywide rule allowing long-term RV occupancy, temporary camping or tiny-home occupancy on private land in Clark County. Ohio's campground rule applies to licensed campgrounds, not to living in an RV on your own parcel22. The practical answer begins with the parcel's zoning authority because Clark County uses county, township, city and village contacts depending on location3. Ask that authority whether the district permits an RV or tiny home as a residence, whether temporary occupancy during construction is allowed, and what size, foundation and utility rules apply. A manufactured home generally cannot be occupied until the state inspector issues an inspection seal, but local placement rules may also apply23.

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

  1. Identify the parcel's zoning authority and district using the county jurisdiction information and zoning maps317.
  2. Confirm the proposed use, setbacks and site layout with that zoning authority; the county office covers seven named townships2.
  3. Secure a driveway permit from the Clark County Engineer or township road department for a new or relocated driveway; repairs do not require that permit8.
  4. Complete the health district's septic site review and obtain installation and operation permits; the published site-approval fee is $50515.
  5. Submit the building application and required plans, then pay the applicable fees before issuance13.
  6. Do not begin covered building work until the plans are approved10.
  7. Complete required building and septic inspections, and submit the listed final documents before a certificate of occupancy is issued when the project requires one2411.

What to check before you buy land in Clark County

Before buying, identify the zoning authority and district, then get written answers on the proposed home, accessory structures, RV use, setbacks and minimum lot or dwelling size317. Confirm legal road access and whether a new or relocated driveway needs county-engineer or township approval8. Make septic suitability a contract contingency: only about 14% of mapped soils avoid a “very limited” rating for a conventional drain field21. If public sewer is accessible and available under Ohio's distance and capacity rules, connection may be required instead of onsite disposal25. For a private well, Ohio requires a board-of-health permit before covered construction, alteration or sealing work begins7. We could not confirm Clark County's floodplain-development requirements, so ask the Building Department whether floodplain review or an elevation certificate applies before closing.

Watch-outs

  • Zoning in Clark County is not handled by one office: the correct county, township, city or village contact depends on the parcel's location3.
  • We could not confirm whether Clark County or any of its townships allow living in an RV or tiny home on private land outside a licensed campground; Ohio's campground rules govern licensed campgrounds only, so ask the zoning office for your specific township before you plan to live on the land that way2216.
  • Real-estate septic inspections are performed on request, and no law requires a local-health-district inspection merely because a house is sold20.
  • A new or relocated driveway needs a permit from the Clark County Engineer or township road department; driveway repairs do not8.

    • The authority is exercised by resolution and must be in accordance with a comprehensive plan.
    • The authority applies to unincorporated territory of the county.
    • The statute begins with the exception phrase “Except as otherwise provided in this section,” so the limitations in ORC Chapter 303 apply.
    • For nonresidential property only, the county may regulate height, bulk, number of stories, size, lot coverage, yards, courts, open spaces, and population density.
    • Agricultural uses and agricultural buildings are subject to the limitations in ORC 303.21; the statute also contains limitations for public utilities, railroads, telecommunications towers, alcoholic-beverage sales, oil and gas drilling, and permanently sited manufactured homes.
    • Activities regulated under ORC Chapters 1513 and 1514 may be regulated only in the interest of public health or safety, and Chapter 1514 activities must be provided for as permitted or conditional uses as specified by ORC 303.02.
    “the board of county commissioners may regulate by resolution, in accordance with a comprehensive plan”
  • county building authorityGeneral

    County commissioners may adopt and enforce local residential building regulations in unincorporated areas and may operate certified county building departments that enforce state residential and nonresidential building codes, accept and approve plans, and conduct inspections.

    • Local residential building regulations may be enforced within the unincorporated area or within districts established in the unincorporated area.
    • A local residential building regulation may not differ from the state residential building code unless it addresses subject matter not addressed by that code or is adopted under ORC 3781.01.
    • An existing structures code must concern subject matter not addressed by, and may not conflict with, the state residential building code.
    • County building departments may enforce state codes only for the types of buildings and subject matters for which they are certified.
