Wake County UDO §5-21 caps principal residential building heights at 35 ft (R-30, R-40, R-80) or 45 ft for some specific districts. Accessory structures are typically capped at 25 ft or the height of the principal structure, whichever is less. Steeples, antennas, and chimneys are exempt.
Standard residential height limit under Wake UDO §5-21 is 35 ft measured to the average roof height. Some districts (e.g., R-40W within the Falls Lake Watershed) cap at 30 ft. Accessory structures are limited to 25 ft or the principal building height — whichever is less. Building height exclusions per UDO: chimneys, church steeples, water tanks, antennas, and silos can exceed the height limit. Solar panels mounted on a roof do not count toward the height limit if they don't exceed 3 ft above the roofline. Height variances are common requests at the Board of Adjustment.
Over-height construction: stop-work order, civil penalty under UDO Art. 22, owner bears cost of reduction. Mid-build violations may require structural removal of top portions.
