Do I need a permit for pavers, driveway, or hardscape in Unincorporated Hamilton County?
It depends. Whether pavers, driveway, or hardscape needs a permit in Unincorporated Hamilton County comes down to the details of your project.
In Hamilton County, permits outside the cities are handled by the Hamilton County Planning and Development, Buildings and Inspections Division, reachable on 513-946-4550 at https://www.hamiltoncountyohio.gov/government/departments/planning_and_development/buildings_and_inspections. Its online permit portal is http://cagis.hamilton-co.org/opal/. This is a certified building department serving communities in Hamilton County that do not run their own. Ohio certifies municipal, county and township departments alike, so confirm which one covers your address. Patios are often exempt while driveway and right-of-way work is not, so confirm which side of that line your project falls on. Section 102.10 of the Residential Code of Ohio, work exempt from approval, covers sidewalks and driveways not more than 30 inches above grade and not over any basement or story below. Patios are not on that list, so do not assume a paver patio is exempt in Ohio. Added impervious surface can also trigger local zoning, grading or drainage review, so confirm before you begin. A structural retaining wall over 4 feet high, or any wall supporting a surcharge, a raised deck, or landscape electrical work requires its own permit and is not exempt. Ohio words 102.10 as an exemption from approval rather than from the rules. Exempt work still has to comply with the applicable provisions of the rules of the Board of Building Standards.
