Do I need a permit for water heater replacement in Greensboro?
Yes. In North Carolina, water heater replacement generally requires a permit, and Greensboro 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. Greensboro requires a separate plumbing permit for water heater work, so even a straight replacement needs its own permit. A gas water heater also involves the gas or mechanical trade, which is a separate permit under the city's per-trade rule. A homeowner may pull the plumbing permit only for a home they own and occupy that is not for sale or lease, and must sign the affidavit of ownership. 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. Guilford County's own permitting office is the Guilford County Inspections Department, reachable on 336-641-3707 at https://www.guilfordcountync.gov/government/departments-and-agencies/inspections. Its online permit portal is https://citizenaccess.guilfordcountync.gov/energov_prod/selfservice#/home. It issues permits for the unincorporated county. If your city does not run its own building department, this is the office that will handle the job, and that is more common in North Carolina than most states: the county is often the building authority even inside city limits, with the city handling only zoning. Ask whether a like-for-like swap is exempt at your address, since that answer varies between the county and its municipalities.
