Do I need a permit for water heater replacement in Unincorporated Williams County?
Unincorporated Williams County does not issue residential building permits. Williams County has no Board of Building Standards certified residential building department, so no county residential building permit is issued in unincorporated areas. Township zoning permits and county health department (septic/well) permits may still apply.
The requirements below come from Ohio rules and describe the standard the work must still meet. They are not a statement that Unincorporated Williams County will issue you a permit.
Yes. In Ohio, water heater replacement generally requires a permit, and Unincorporated Williams County 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.
