Do I need a permit for hvac replacement or installation in Cincinnati?
Yes. In Ohio, hvac replacement or installation generally requires a permit, and Cincinnati is no exception.
Under the Residential Code of Ohio, installing or replacing a furnace, air conditioner, heat pump, or other HVAC equipment is mechanical work that requires a permit in most Ohio jurisdictions and is not covered by the minor-repair exemption. Any new electrical circuit or gas line for the equipment requires the corresponding trade permit. Cincinnati Buildings and Inspections requires a separate permit for HVAC work, so a like-for-like furnace or air conditioner changeout is generally not exempt; mechanical permits are among the permits you can apply for online through the City's ezTrak system. Building permits generally cannot be issued until all applicable contractors are registered with the City (Contractor Registration, 513-352-3271), and mechanical contractors should hold the correct Ohio Construction Industry Licensing Board (OCILB) license. A gas furnace can add a gas-piping scope, and the work must meet the Ohio Residential Code as adopted by the City, so confirm the full scope before scheduling.
