Gwinnett UDO typically limits residential structure height to 35-40 feet in R-100 and similar zones. RA-200 follows similar residential height limits. Accessory structures generally capped at 15-20 feet or below primary dwelling height.
Height limits in unincorporated Gwinnett vary by zone and are measured from average finished grade to the midpoint of the roof for pitched roofs or to the highest point for flat roofs, per the UDO. R-100 principal dwelling typically limited to 35 feet or about 2.5-3 stories. RA-200 rural zones similar residential caps with exceptions for agricultural structures (barns, silos often exempt or higher allowed). R-TH and RM may allow 40-45 feet given multifamily/townhouse scale. Commercial zones vary widely (C-1 lower, C-2 higher); M-1/M-2 industrial can exceed 50-60 feet. Accessory structures typically limited to 15-20 feet and may not exceed the height of the principal dwelling. Antennas, chimneys, HVAC, and similar appurtenances generally exempt up to reasonable limits. Overlay districts near airports (DeKalb-Peachtree, Lawrenceville-Gwinnett) impose FAA Part 77 surface restrictions. Height variances require Board of Appeals action.
Over-height construction: stop-work, demolition of excess height, fines; airport zone violations can involve FAA coordination.
