Do I need a permit for hvac replacement or installation in Dayton?
Yes. In Ohio, hvac replacement or installation generally requires a permit, and Dayton 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. Dayton issues a separate HVAC permit through the Division of Building Inspection, so a furnace or air conditioner changeout is generally not exempt; confirm the scope at 937-333-3883. Warm air heating contractors must register and post a bond with the City before a permit is issued, and 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 Residential Code of Ohio as enforced by the City, so confirm the full scope before scheduling.
