Full Breakdown
The Wake County UDO's Sec. 5-11-2 table for non-watershed residential districts sets a flat 35-foot maximum building height in the R-80, R-40, R-30, R-20, R-15, R-10 and HD zones. In the R-5 district, the 35-foot cap can be exceeded under a sliding formula: one additional foot of height for every three feet a building is set back beyond the required front, side and rear setbacks, whichever calculation yields the greater allowed height.
Violations & Fines
Building above the district's height limit without an approved variance or Special Use Permit is a zoning violation enforceable by the Wake County Planning Director; noncompliant structures can be denied a certificate of occupancy.
