Do I need a permit for window or exterior door replacement in Unincorporated Polk County?
It depends. Whether window or exterior door replacement needs a permit in Unincorporated Polk County comes down to the details of your project.
Under NCGS 160D-1110, a simple like-for-like window or door swap in a one- or two-family dwelling that costs $40,000 or less and does not affect structure, egress, or life safety can fall under the minor-work exemption, but the moment you resize an opening, alter a header, or change an egress window a permit is required. The exemption does not cover any structural, electrical, plumbing, or mechanical work associated with the change. Enlarging an opening, moving it, or cutting a new one is structural work. Exemptions that cover replacing a unit in its existing opening do not reach it, so a permit is required. Changing an opening usually means a new or resized header, and many jurisdictions want a beam detail or engineering before they will issue, so allow for that in the schedule. Polk County's own permitting office is the Polk County Building Inspections office, reachable on 828-894-3739 at https://www.polknc.gov/building_and_fire_inspections.php. 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 changing the size of an opening is structural work and is treated differently.
