Do I need a permit for water heater replacement in Dayton?
Yes. In Ohio, water heater replacement generally requires a permit, and Dayton 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. Dayton issues a separate plumbing permit through the Division of Building Inspection, so a water heater replacement is generally not exempt; confirm the scope at 937-333-3883. Plumbing contractors must register and post a bond with the City before a permit is issued, and should hold the correct Ohio Construction Industry Licensing Board (OCILB) license, though an owner-occupant of a single-family home may do their own permitted work. A gas water heater adds a fuel-piping and venting scope under the Residential Code of Ohio, so confirm whether a gas inspection applies to your replacement.
