For a new home in Morrow County, Ohio, start by identifying the parcel's township: zoning and the office that handles land-use approval vary by township, and the available county material does not establish one countywide residential structural-permit answer.12 The Morrow County Health District separately permits new, replacement and altered household sewage systems.3

Do you need a building permit in Morrow County, Ohio?
Morrow County does not have a single, confirmed residential structural-permit answer for every rural parcel in the available county material; the safe first step is to identify the parcel's township and then confirm which certified department, if any, has residential jurisdiction.2 Ohio requires plan submission for covered construction when a certified municipal, township or county building department has jurisdiction, but the state rule also says that the described submission is not required when no certified residential department has jurisdiction.2
Do not confuse zoning approval with structural-code approval. Morrow County's township directory shows a mix of county-administered zoning, township-administered zoning and unzoned townships, so a parcel may have a zoning contact even where the structural-permit path is different.1 Ohio has adopted residential and nonresidential building codes, and certified local departments enforce them within their certification.8
Who handles building and zoning permits in Morrow County?
Begin with the Morrow County Zoning Office and the county township directory, because the zoning administrator depends on where the parcel lies.9 The directory identifies county-wide zoning in Bennington, Congress, Gilead, Harmony, North Bloomfield and Washington townships; it identifies separate township zoning in other listed townships and no zoning in Franklin, Perry and Peru townships.1
The county zoning office can route a parcel that participates in county-administered zoning, while a separately zoned township should be handled by that township's zoning contact.1 Ask the applicable zoning office which structural-code department has jurisdiction before ordering plans or starting work, because certified departments may enforce only the building types and subjects covered by their certification.10 Permit fees likewise depend on the certified department's locally adopted schedule when a local department handles the submission.11
Does Morrow County have zoning?
Zoning in Morrow County varies by township rather than following one rule for every unincorporated parcel.1 Bennington, Congress, Gilead, Harmony, North Bloomfield and Washington use county-wide zoning; other listed townships administer their own zoning, while Franklin, Perry and Peru are identified as not zoned.1 A buyer should therefore verify the township from the tax parcel and contact the corresponding office before relying on a listing's claim that land is unrestricted.
The available reviewed material does not confirm countywide standards for setbacks, minimum dwelling size, lot coverage, building height, RV occupancy, tiny-home occupancy or accessory dwellings. Ask the applicable county or township zoning office about each intended use and structure. Ohio law allows counties to regulate land use in unincorporated territory by zoning resolution, subject to statutory limits, but that general authority does not prove a particular restriction applies to a Morrow County parcel.12
How do septic and well permits work in Morrow County?
The Morrow County Health District applies and enforces the household sewage rules for systems serving one-, two- and three-family dwellings.5 The district issues permits for new, replacement and altered sewage treatment systems and inspects their installation, operation and maintenance.313
For a vacant parcel, submit the site-review application, soil evaluation, system design and fee; the Health District schedules the appointment after receiving that package.14 This early review matters because none of the county's mapped soils are rated without severe limitations for a conventional septic drain field, so budget for careful siting and the possibility of a more involved design.15 A private well also needs a valid board-of-health permit before construction, alteration or sealing, subject to the rule's stated exceptions.6 The Health District also evaluates proposed lot splits for sewage suitability.16
Can you live in an RV or tiny home on land in Morrow County?
We could not confirm a single private-land RV or tiny-home occupancy rule for all of Morrow County, and the answer may turn on the parcel's township zoning.1 Before buying, give the applicable zoning office a precise description of the unit, foundation, utilities, intended duration and whether it will be occupied during construction. The same check is necessary for an accessory dwelling or a manufactured home because local placement rules were not confirmed.
Ohio's campground rule governs licensed campgrounds and temporary campgrounds; it does not answer whether someone may occupy an RV on a private residential parcel.17 A manufactured home regulated under Ohio's installation rules generally cannot be occupied until an inspector issues an inspection seal, with a stated temporary-occupancy exception.18 Septic approval remains a separate issue for any proposed dwelling that will use an onsite sewage system.3
Building a home in Morrow County: what are the steps?
- Identify the parcel's township and whether its zoning is county-administered, township-administered or absent.1
- Ask the applicable zoning authority about the proposed use, setbacks, dwelling type and any zoning certificate, and ask which certified structural-code department has jurisdiction.92
- Start the Health District site review with the soil evaluation and system design before fixing the house location.14
- Obtain the required sewage-system permit and arrange the district's installation inspections.313
- Apply to the board of health if the project includes a private well.6
- Contact the County Engineer when a driveway culvert, road cut or work in a county-road right-of-way is involved; applicability is limited to the Engineer's permit program and does not establish a permit for every driveway.1920
- Do not begin building-code work until any required plans are approved by the authority with jurisdiction.21
What should you check before buying land in Morrow County?
Confirm the township and zoning administrator first, then request written answers for the planned home type, setbacks, accessory structures, RV use and any minimum lot or dwelling standards.1 For a proposed split, involve the Health District early because it evaluates lot splits for approval, while Ohio separately regulates subdivision and platting.1622
Treat septic feasibility as a major due-diligence item: the soil dataset rates none of the county's soils as free of severe conventional drain-field limitations, and the Health District requires a site review and design package.1514 Check road ownership and ask the County Engineer whether the access design needs a culvert or right-of-way permit.19 Also confirm whether a public or regional sewer is accessible and available, because Ohio's connection rule can apply at stated distance and capacity thresholds.23 The median property-tax bill is about $2,208 per year, useful for budgeting but not a parcel-specific tax quote.24
Watch-outs
- A township shown as unzoned is not proof that no building-code, septic, access or subdivision approval applies; confirm each approval separately.132
- A real-estate septic inspection for a sale or refinance is not required by the Morrow County Board of Health, but system permits and installation, operation and maintenance inspections are separate requirements.13
- The county's residential structural-permit authority, owner-builder treatment, floodplain permit rules and private-land RV occupancy could not be confirmed; ask the applicable zoning authority and Health District before committing to a site plan.71
