Do I need a permit for water heater replacement in Columbus?
Yes. In Ohio, water heater replacement generally requires a permit, and Columbus 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. Columbus BZS lists replacing a hot water tank among typical residential projects that require a permit, filed as a plumbing permit. Water heater work is generally pulled by a contractor registered with the City of Columbus, and a fuel-fired unit may need gas and venting review under the codes adopted locally. Switching between electric, gas, or tankless equipment can add electrical or gas scope, so confirm the requirements with BZS before purchasing.
