Licking County, Ohio requires building permits for new homes, additions and specified residential alterations in the county department's jurisdiction1. Apply first for a township zoning certificate, or Health Department approval where there is no zoning2. Township zoning varies, while the county Health Department permits and inspects household sewage systems34.

Do you need a building permit in Licking County, Ohio?
Yes. In the Licking County Building Code Department's jurisdiction, new dwellings and additions need permits; detached garages, sheds and carports over 200 square feet also need permits1. A deck needs a permit when it is attached, exceeds 200 square feet, rises more than 30 inches above grade or serves the main entry1. Incorporated jurisdictions can impose additional or different requirements, so confirm which building department serves the parcel1. Before county submission, obtain a zoning certificate from the local zoning inspector, or Health Department approval where the township has no zoning10. Ohio requires approval of applicable plans before construction begins11. We could not confirm a general owner-builder exemption; an owner acting as contractor should ask the Building Code Department what permits, licensed trades and inspections apply6.
Who is the Licking County building department, and how do you reach them?
The Licking County Building Code Department at 675 Price Road in Newark handles building permits and construction-document review in its jurisdiction10. A submission requires the completed application, a zoning certificate or Health Department approval where there is no zoning, and two complete sets of plans and specifications2. The county publishes applications, checklists, procedures and a fee schedule online2. The available fee schedule is dated 2013 and may not be current, so request a current calculation before budgeting or submitting payment12. The department reviews documents for code compliance10. Planning and Development can direct a landowner to the correct township zoning inspector, but the township handles its own zoning documents and enforcement313.
Does Licking County have zoning?
Local zoning varies across unincorporated Licking County: 19 of its 25 townships are zoned and 6 are un-zoned3. Each township prepares, implements and enforces its own zoning documents, while municipal zoning may apply inside an incorporated city or village3. Licking County Planning and Development directs landowners to the appropriate township zoning inspector13. Ask that inspector about permitted uses, setbacks, minimum lot size, dwelling size, accessory dwellings, RV placement and tiny homes before relying on a listing description. An un-zoned township does not remove the county building-permit or Health Department approval steps15. Agricultural structures can qualify for a state building-code exemption under stated agricultural-use and retail-income conditions, and the applicable zoning inspector must certify the specific agricultural use for the additional exemption8.
How do septic permits work in Licking County?
The Licking County Health Department permits and inspects household and small-flow sewage treatment systems4. Obtain both an installation permit and an operating permit before installing a new, altered or replacement system, and arrange inspection before the installer backfills it5. New installations receive another inspection 12 months after completion; off-lot discharging and drip-irrigation systems are inspected annually, while soil-absorption systems are inspected every 5 years14. Start with a site evaluation because soil, groundwater, slope and bedrock affect feasibility, and not every lot can support an on-lot system5. Only 3.6% of county soils are rated without severe limits for a conventional drain field, so do not assume a conventional layout will pass15. A Health Department permit is also required before installing or altering a well, cistern, hauled-water tank or drinking-water pond7.
Can you live in an RV or tiny home on your land in Licking County?
We could not confirm one countywide rule allowing RV or tiny-home occupancy on a private parcel. The practical answer begins with the parcel's township zoning inspector because township zoning varies, and a city or village may have separate municipal zoning3. Ask specifically about using an RV during construction, time limits, utility connections, minimum dwelling size and whether a tiny home is treated as a dwelling, accessory structure or vehicle. Ohio's campground rule regulates vehicle placement, density and sanitation in licensed campgrounds, but it does not answer residential RV occupancy on an individually owned parcel16. A manufactured home generally cannot be occupied until an inspector issues its installation seal, subject to the temporary-occupancy exception17. Any private septic or water system still needs the applicable Health Department permits57.
What are the steps to build a home in Licking County, in order?
- Identify the township and ask Planning and Development which zoning inspector serves the parcel13.
- Obtain the township zoning certificate, or Health Department approval where there is no zoning2.
- Arrange the sewage site review early because site conditions control whether and how an on-lot system can be built5.
- Obtain sewage installation and operating permits, plus a private-water permit if the project needs a well or another private supply57.
- Submit the building application, prior approval and two complete plan sets to the Building Code Department2.
- Confirm the current local fee and inspection schedule before work begins; Ohio requires inspections of regulated work after plan approval1819.
- Keep the septic installation open for inspection before backfilling and plan for its later operation-and-maintenance inspections14.
What should you check before you buy land in Licking County?
Confirm the parcel's township and incorporated status because zoning jurisdiction changes by location3. Make an offer contingent on acceptable sewage and water results when those systems matter: only 3.6% of county soils are rated without severe limits for a conventional drain field, and the Health Department warns that not every lot can support an on-lot system1520. Ask whether public sewer is accessible; Ohio can require connection when capacity and distance conditions are met21. Verify legal road access and ask the road authority whether a driveway approval applies, because we could not confirm a general county-road driveway rule. For a land division, Ohio generally regulates a split when any resulting parcel is under 5 acres, subject to statutory exemptions and local planning rules9. Finally, price clearing and grading from the actual site rather than county averages: 39.5% of county land is wooded and 87.7% has a slope of 15% or less2223.
Watch-outs
- The published county fee schedule is dated 2013 and may not be current; ask the Building Code Department for the current total before submitting payment12.
- We could not confirm a general owner-builder exemption; ask the Building Code Department what applies when the owner acts as contractor6.
- We could not confirm a parcel-wide answer for RV or tiny-home occupancy; ask the township zoning inspector or the applicable city or village zoning office3.
