Do I need a permit for water heater replacement in Apex?
Yes. In North Carolina, water heater replacement generally requires a permit, and Apex is no exception.
A water heater changeout generally requires a plumbing permit and must be performed by a licensed contractor. A few North Carolina jurisdictions allow a narrow exception for reconnecting an existing electric water heater in the same location at the same or lower capacity, but most require a permit, so confirm with your local department. Switching fuel type, relocating the unit, or altering gas or venting is not covered by any exemption and requires a permit. Water heater replacement is a plumbing modification, and all installations or modifications to plumbing systems require a permit in Apex. Plumbing work is excluded from the North Carolina minor-work exemption, so a permit is required regardless of cost. Gas water heaters may also need a mechanical or gas permit. A gas fired water heater, a change in size, or a move to a new location falls outside like for like exemptions, which cover a same size electric unit reinstalled in the same place. Gas work normally needs its own mechanical or gas permit and a pressure test, and relocating the unit can change venting, combustion air, drain pan, and expansion tank requirements. Wake County's own permitting office is Wake County Permits and Inspections. It issues permits for the unincorporated county, and in North Carolina the county is often the building authority even inside city limits, so confirm which applies to your address. Plumbing work is an express exception to the $40,000 exemption, so this generally needs a permit even on a modest job.
