Do I need a permit for window or exterior door replacement in Apex?

Permit may be required

It depends. Whether window or exterior door replacement needs a permit in Apex 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. 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. A like-for-like swap under $40,000 with no structural framing change can be exempt; enlarging or moving an opening is structural and is not. Replacing windows or doors in an existing opening may fall under the North Carolina minor-work exemption, but altering, enlarging, or adding an opening changes the structure and requires a permit. Verify with Town of Apex Building Inspections and Permitting. Egress and safety-glazing requirements of the NC Residential Code still apply even when a permit is not required.
