Westerville residential height limit is 35 feet or 2.5 stories in R-1 and R-2 districts under Zoning Code 1143.05. Accessory structures capped at 15 feet. Commercial uptown district allows up to 45 feet with historic design review. FAA Part 77 airspace restrictions apply near John Glenn Columbus International Airport (CMH) south of the city.
Westerville Zoning 1143.05 caps residential principal structures at 35 feet measured from average grade to mean roof height, or 2.5 stories, whichever is less. Chimneys, antennas, and steeples are exempt. Accessory structures (detached garages, sheds) are limited to 15 feet. Uptown B-1 district permits 45 feet subject to Architectural Review Board approval for compatibility with historic Otterbein and uptown character. Because John Glenn Columbus International Airport (CMH) is roughly 10-15 miles south, FAA Part 77 Notice of Proposed Construction (Form 7460-1) may be required for structures over 200 feet or on elevated sites within the conical surface; most residential builds are unaffected.
Height violation: stop-work order and removal. Unreviewed uptown structure: denial of certificate of occupancy until ARB approval obtained.
