Do I need a permit for water heater replacement in Cincinnati?

Permit required

Yes. In Ohio, water heater replacement generally requires a permit, and Cincinnati is no exception.

Replacing a water heater is plumbing work (and gas or electrical work for the connection), so it generally requires a permit under the Residential Code of Ohio in jurisdictions that enforce the code. Switching fuel type, relocating the unit, or altering gas or venting adds work that is never covered by any exemption and requires a permit. Cincinnati Buildings and Inspections requires a separate permit for plumbing work and fixtures, so a water heater replacement is generally not exempt; plumbing repair permits are among the permits you can apply for online through the City's ezTrak system, and plumbing questions go to 513-352-3280. A gas water heater adds a fuel-piping and venting scope, so confirm whether a gas inspection applies to your replacement. Building permits generally cannot be issued until all applicable contractors are registered with the City, and plumbing contractors should hold the correct Ohio Construction Industry Licensing Board (OCILB) license, so verify before hiring.
