Full Breakdown
Apex's Unified Development Ordinance sets maximum building height by zoning district in the Sec. 5.1.1 dimensional table. In the Rural Residential (RR) district, a single-family home is capped at 36 feet, alongside a 40-foot front, 15-foot side and 25-foot rear setback; the Residential Agricultural (RA) district lists the same 36-foot cap. Sec. 5.2.4 measures height from the finished floor to the roof's highest point at the front elevation, excludes small cupolas and chimneys, and allows parapet walls up to 5 feet above the limit. These standards reach both Apex's town limits and its mapped extraterritorial jurisdiction. The UDO was codified July 2021: verify against current zoning before designing.
Violations & Fines
Building above a district's height cap violates UDO Sec. 11.1.3, which makes it 'unlawful for any person to develop or use any building or structure' in Apex or its ETJ against the Ordinance; the Town can abate, enjoin or prosecute.
