Building permits, zoning and septic rules in Crawford County, Ohio

Residential building permits are limited in Crawford County, Ohio: the Richland County Building Department's published residential coverage is the Village of Crestline, and its pages do not name a residential permit authority for the rest of the county^2,7. Ohio's owner-builder rule applies where no certified residential building department has jurisdiction: the owner need not submit construction documents, request inspections or obtain a certificate of occupancy, though zoning, floodplain, septic and health rules still apply¹⁸. Confirm with your township or village whether one covers your parcel.

Commercial work is different. Richland County enforces the Ohio Building Code for commercial projects in all Crawford County townships and in Bucyrus, Crestline, Galion, New Washington and Tiro, with inspections on Tuesday and Thursday and a business day's notice^7,19. The department's FAQ excludes Galion, so confirm Galion directly¹⁹. Fees depend on project type and size, and applications received on or after January 2, 2026 fall under the new fee schedules^19,20.

Crawford County Public Health administers the household sewage program and reviews soil evaluations and system designs before a new lot is developed⁸. Reach the office at 1520 Isaac Beal Rd., Bucyrus, Ohio 44820, phone (419) 562-5871²¹. Driveway, address and floodplain matters go through the Crawford County Engineer's Office at 815 Whetstone Street, Bucyrus, Ohio 44820, phone 419-562-7731²². Right-of-way applications are ordinarily reviewed within seven business days unless complexity requires more time²². Commercial construction, and residential construction in Crestline, go to the Richland County Building Department in Mansfield at 419-774-5517^7,19.

Crawford County has no county zoning¹. Zoning is a local patchwork: cities, most incorporated villages and some townships zone, and the Crawford County Engineer lists zoning contacts for Bucyrus, Crestline, Galion, Chatfield, New Washington, North Robinson, Jackson Township, Jefferson Township and Polk Township¹. Galion, Crestline and New Washington each administer their own zoning inside their limits^3,4,5. The county's rules apply to unincorporated land only where a township has not zoned it, and we could not confirm countywide setbacks, minimum lot or dwelling size, RV use or tiny homes, so ask the zoning contact for the parcel¹.

Farm buildings get two exemptions. A building incident to agricultural use, and not used in retail trade, is exempt from the state building-code sections listed in ORC 3781.06¹³. Township zoning cannot regulate agriculture or its buildings on lots over five acres, and on a platted subdivision of 15 or more contiguous lots, it may regulate agriculture on lots of one acre or less¹⁴.

Crawford County Public Health requires an approved site and a permit before a sewage treatment system is installed, altered, or operated; the installation permit is valid for one year⁶. An approved on-site system is allowed where sanitary sewer service is not accessible²³. If sewer service is accessible or later becomes accessible, the dwelling must connect and abandon the on-site system unless an exception applies⁶. Crawford County Public Health inspects a new system no later than 12 months after installation, and deficiencies must be corrected within the timeframe the department sets⁸. Mound, drip-distribution and NPDES systems also require a service-provider contract for monitoring and inspection⁸. Soils make early review essential: 0% of Crawford County's soils are free of severe limitations for a conventional drain field¹². A drilled well or other private water system needs an installation permit, and that permit is valid for one year²⁴. Fees are published: a new system permit totals $984.87, a replacement $965.09 and an alteration $435, with a $171.87 site review fee and a $150 design application fee⁹. Starting work before the permit adds 25% of the local fee⁹. All new and altered water systems are permitted through Crawford County Public Health, whatever city, village or township the parcel is in²⁵.

We could not confirm a general Crawford County rule allowing or prohibiting long-term RV occupancy on private rural land, so ask the zoning contact for the city, village or township. Ohio's campground rules answer a different question: a campground generally needs a license, and a private use is exempt only when no one receives anything of value from it¹⁰. A temporary campground needs plan approval and a license, may operate no more than seven consecutive days, and may use the same tract no more than 21 days in a calendar year¹⁰. Temporary-campground sewage must meet state standards; individual hookups need Ohio EPA approval, while an approved dump station may be used instead¹¹. In mapped flood-hazard zones an RV must meet the rule's stay, highway-readiness, or permit and anchoring conditions²⁶. Tiny-home occupancy remains unconfirmed.

A permanently sited manufactured home is allowed where single-family homes are allowed, subject to uniform local zoning and possible deed restrictions¹⁶. A used or relocated manufactured home must meet Ohio's installation standards, and the more restrictive requirement governs where sections differ¹⁷.

1. Identify the city, village, or township governing the parcel and ask its zoning official what local approval applies¹.
2. Ask the County Engineer whether the site is in a floodplain; any development there needs a Flood Hazard Area Development Permit before work begins²⁷.
3. Contact Crawford County Public Health for septic site review and confirm whether an accessible sanitary sewer instead requires connection^6,8.
4. Obtain the property's mailing address from the Crawford County Engineer before seeking the septic installation permit^8,22.
5. Obtain the septic permit and, for a drilled well or other private supply, the private-water installation permit^6,24.
6. Apply to the County Engineer if a driveway or drivepipe enters county road right-of-way²².
7. After septic installation, complete the final inspection and the required inspection no later than 12 months after installation⁸.
8. For a Crestline home or any commercial project, apply for building permits through the Richland County Building Department; elsewhere, ask the township or village whether a residential building department has jurisdiction^7,18.

Start with septic feasibility: none of Crawford County's mapped soils are rated free of severe limitations for a conventional drain field, so obtain a site evaluation before choosing a house location or system budget¹². Determine whether sanitary sewer service is accessible, because accessible service can require connection instead of a new on-site system⁶. Confirm the parcel's city, village or township zoning authority before buying, because the county itself does not zone¹. Ask the County Engineer whether planned grading, construction, utilities, or other work lies in a floodplain and needs a development permit²⁷. If land will be split or transferred, the Tax Map Department reviews surveys and legal descriptions against county transfer, subdivision, and state boundary-survey standards²⁸. Crawford County's effective property tax rate is about 1.2%, and its median annual property tax bill is about $1,509¹².
