Gulfport, FL Building Setbacks & Zoning: Structure Height Limits (2026)

Section 22-5.03(g) states the R-1 single-family residential district's height cap plainly: thirty feet, with no building exceeding two stories of living area. The identical thirty-foot, two-story limit repeats for the R-1A district in § 22-5.02(g) and the R-3 district's single-family and duplex homes in § 22-5.05(g). R-3 treats multiple-family buildings differently: § 22-5.05(g)(1) allows them up to forty-five feet, while single-family and duplex homes in that same district stay at thirty feet and two stories under § 22-5.05(g)(2). Commercial districts run higher across the board: CL-1, CL-2, CG and the institutional (I) district all cap most uses at forty-five feet under their respective (g) subsections, though single-family or duplex dwellings built within those commercial districts still drop back to the thirty-foot, two-story residential standard. Compliance is checked at building permit plan review by the Building Official before construction begins, since the code ties actual construction to a valid permit.
