Do I need a permit for water heater replacement in Unincorporated Cobb County?
Most likely yes. Water heater replacement usually requires a permit in Georgia. Confirm the specifics with Unincorporated Cobb County.
Water heater replacement requires a plumbing permit in Georgia jurisdictions such as Atlanta, even for a like-for-like swap; code items like a T and P discharge line and expansion tank are checked. Gas or electrical changes to serve the unit may require a coordinated trade inspection. Cobb County's own permitting office is the Cobb County Development and Inspections, reachable on 770-528-1000 at https://www.cobbcounty.gov/community-development/building-development/permitting. Its online permit portal is https://cobbca.cobbcounty.gov/CitizenAccess/default.aspx. It issues permits for the unincorporated county. If your city does not run its own building department, and many smaller Georgia municipalities do not, this is the office that will handle the job. Ask whether a like-for-like swap is exempt at your address, since that answer varies between the county and its municipalities. Water heaters are listed as a plumbing item on Cobb County's Subcontractor Permit Request, which covers replacements and states the permit must be issued before work begins. Send it to subpermits@cobbcounty.gov. The gas meter is not authorized until any gas piping test at 15 psi of air is approved by the inspector.
