Do I need a permit for interior remodeling in Unincorporated Hamilton County?
It depends. Whether interior remodeling 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. Each trade normally needs its own permit on top of the building permit, so ask which trade permits your scope will require. The Residential Code of Ohio exempts finish work such as painting, papering, tiling, carpeting, cabinets, and countertops from a permit, but moving or removing walls, or any electrical, plumbing, or mechanical change, requires a permit in most Ohio jurisdictions. Removing or altering a load-bearing wall is structural work and is never exempt. A remodel that moves walls or includes electrical, plumbing, or mechanical work falls outside cosmetic exemptions, which cover finishes such as paint, flooring, trim, and cabinets. Each trade normally needs its own permit and inspection on top of the building permit, and removing or altering a load bearing wall usually requires a beam detail or engineering before the work is approved. Opening walls in an older home can trigger separate lead paint, asbestos, and smoke alarm requirements, so raise those with your department at application time.
