Bessemer, AL Building Setbacks & Zoning: Structure Height Limits (2026)

Birmingham Zoning Ordinance Chapter 5 establishes building height limits by district. R-1, R-2 residential zones limit buildings to 35 feet or 2.5 stories whichever is less. R-3 Multi-Family allows 45 feet. B-1 Neighborhood Business 35 ft; B-2 Community Business 55 ft; B-3 Central Business allows unlimited height subject to FAA airspace and other factors - this is why downtown Birmingham hosts the Wells Fargo Tower (454 ft), Regions Harbert Plaza (391 ft), and the City Federal Building. Height is measured from average finished grade to the highest point of the roof, excluding chimneys, antennas, flagpoles, and mechanical equipment. Mountain Brook Zoning enforces strict 30 to 35 ft residential heights with additional review for tear-down/rebuild projects. Vestavia Hills Code §42 establishes 35 ft residential. Hoover varies by subdivision with PUDs like Greystone allowing some height flexibility. Homewood and Trussville maintain 35 ft residential. Red Mountain and Shades Mountain topography means height measurement can be complex on sloped lots, often measured from the midpoint of the lot's average grade. FAA Part 77 airspace surfaces around Birmingham-Shuttlesworth International Airport (BHM) may limit structure heights in approach corridors including Forestdale, Pratt City, Ensley, and Tarrant. Hillcrest-type subdivisions along ridgelines may have additional ridge-protection height restrictions.
