Are there special requirements for windows/doors in Currituck County?
A. Yes. All windows, exterior doors, and overhead garage doors must meet a minimum design pressure or DP rating. Design Pressure (DP) ratings are determined by the mean roof height of the structure. Information on minimum design pressure ratings is located in Chapter 44, Table 4002 (A) and 4002(B) of the NC State Building Code (2002 International Building Code with North Carolina Amendments).
