Does St. Clairsville, Ohio have zoning, and what does it mean for RVs, lot size and setbacks?

Yes. The City of St. Clairsville has its own zoning ordinance, and it governs the use, size and placement of structures in each district inside the city²⁸. Which district a parcel sits in decides what you can build there, so ask the city's planning and zoning administrator before you plan a project, because the city says zones may change².

We have not read the district-by-district lot sizes, setbacks or RV rules from the ordinance text, so we cannot state them here⁷. Treat RV living, tiny homes and accessory buildings inside city limits as questions for the planning and zoning administrator at City Hall.

Do you need a building permit in St. Clairsville, and who issues it?

The city requires a zoning permit before any construction project or any proposed change in the use of an existing structure¹⁸. That applies whether property owners, renters or contractors do the work⁴.

The city's forms include a certificate of zoning compliance (zoning permit), variance, conditional use, sign, special exception and home occupation applications⁴.

That is the zoning permit. We could not confirm who reviews and inspects building-code permits for a house inside the city, so ask City Hall before you break ground. The regional Mid-East Ohio Building Department that serves Belmont County has no authority over one-, two- or three-family homes⁹.

How do septic permits work in St. Clairsville?

The Belmont County Health Department regulates household sewage treatment systems for one-, two- and three-family dwellings, and a permit is required to install, alter or replace one⁵³¹⁰. The process includes a site and soil evaluation and a system design, and the health department performs a final inspection¹¹.

We could not confirm how the city's own sewer rules apply to a particular lot. A property reached by a county sanitary sewer may be required to connect rather than install a private system¹². Ask the health department and City Hall which applies to your address.

Building a home in St. Clairsville: the steps, in order

1. Call the planning and zoning administrator at City Hall to confirm the parcel's zoning district²⁸.
2. Apply for the zoning permit before work starts¹.
3. Ask City Hall who issues and inspects building-code permits for a dwelling in the city, since we could not confirm that.
4. Contact the Belmont County Health Department for a septic permit or a private water system permit if the lot has no public sewer or water³⁶¹⁰.
5. Check flood maps for the parcel, because the county Floodplain Administrator requires a development permit in mapped flood hazard areas¹³.

What stays with Belmont County, and what should you check before you buy?

The county's rules for unincorporated land do not apply inside the city. For land outside St. Clairsville city limits, see the Belmont County page. Septic and well permits come from the Belmont County Health Department for the district⁵⁶.

Across Belmont County, only about 6% of soils rate as not limited for a conventional septic drain field, so expect a site evaluation¹⁴. Belmont County's median property tax bill is about $1,420 a year¹⁵. These figures are county-level, not specific to the city.

Watch-outs

• The city's zoning map may change, so confirm a parcel's zone with the planning and zoning administrator before you commit².
• A city zoning permit is separate from building-code approval, and we could not confirm who handles building-code permits for homes inside St. Clairsville; call City Hall¹.
• Septic permits and well permits come from the Belmont County Health Department, not the city⁵⁶.

14. Share of soils USDA rates "not limited" for a conventional septic drain field (SSURGO). A strict rating: the median county is about 6% and a tenth of counties are 0%, so a low figure means most lots need a site evaluation or an engineered system, not that septic is impossible.
