Does St. Bernard, Ohio have zoning, and what does it mean for RVs and tiny homes?

Yes. The Village of St. Bernard has its own zoning code, which regulates how property can be used and where structures can be placed¹. The village zoning administrator manages and enforces it, and an approved zoning certificate is required before work begins¹. The village is divided into zoning districts, so setbacks, lot size and height depend on the district your parcel sits in. We could not confirm the village's rules on RV living, tiny homes, minimum dwelling size or accessory dwellings, so ask the⁷ before you buy or build.

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

Yes, construction in St. Bernard needs a building permit, and Hamilton County issues it. Building permits and inspections for the village are issued by the Hamilton County Building Department through its online portal³⁵. The county will not issue a building permit until it has a copy of the approved village zoning certificate⁸. Permits issued before 2026 were village-issued, so older records are still on the village portal³. Reach the county at⁹.

What does a St. Bernard zoning certificate cost, and how do you apply?

The fee for a zoning certificate is $50². Applications go through the village's iWorQ web portal with a site plan⁸. A village zoning certificate is needed for fences, sheds, signs, pools, new homes and additions, while roof, furnace, plumbing and electrical work go to the county first⁸. County building permit fees are set by Hamilton County; we did not confirm them, so check its published fee schedule or call⁹.

What building code applies in St. Bernard?

St. Bernard's building code applies the Residential Code of Ohio to one-, two- and three-family dwellings and the Ohio Building Code to other buildings⁶. The village council may add regulations that do not conflict with state law⁶. Ohio's Board of Building Standards writes the state residential and nonresidential codes¹⁰.

How do septic permits work in St. Bernard?

Hamilton County Public Health approves plans for household sewage treatment systems throughout Hamilton County except Cincinnati, Norwood and Springdale⁴. A home not connected to a public sewer needs a sewage treatment system¹¹. After inspection and paperwork, the invoice must be paid within 30 days, and the permit is issued once the system is approved¹². Homes within a certain distance of a sanitary sewer must connect to it instead¹³. We could not confirm village-specific septic or well rules, so ask¹⁴.

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

1. Call the village zoning administrator about your parcel's district and what is allowed⁷.
2. Submit the zoning certificate application with a site plan through the village portal and pay the $50 fee⁸².
3. Apply for the building permit with the Hamilton County Building Department using the approved certificate³.
4. If you are not on public sewer, get septic approval from Hamilton County Public Health⁴.
5. Call in the required inspections through the county⁵.

What to check before you buy in St. Bernard

Confirm the parcel's zoning district with the village, since lot size, setbacks and height vary by district and we could not confirm them¹. Ask whether a sanitary sewer is close enough to require connection¹³. Property tax is a county-level figure: Hamilton County's effective rate is about 1.5%¹⁵. For land outside the village, see the Hamilton County page; county rules there do not apply inside St. Bernard¹⁶.

Watch-outs

• Since the start of 2026 the village no longer issues building permits; a contractor quoting a village permit is working from an old process³.
• The county will not issue a building permit without the approved village zoning certificate, so apply for the certificate first⁸.
• We could not confirm village rules on RV living, tiny homes, minimum dwelling size, setbacks or lot size; ask the village zoning administrator before relying on them⁷.
