West Palm Beach, FL Building Setbacks & Zoning: Lot Coverage Limits (2026)

Under Chapter 94 of the West Palm Beach Code of Ordinances, lot coverage is not a citywide dimensional standard: it is defined and regulated only inside the city's historic residential contextual districts. Sec. 94-86 defines lot coverage (LC) as "a regulatory technique, generally expressed in numeric fashion, which relates total developable site area and the building footprint (square feet) of development permitted on a specific site," and ties the calculation to historic residential districts specifically. The counting rules matter: a fully enclosed roofed structure counts 100 percent of its ground floor toward coverage, an attached carport or porch enclosed on two sides or less counts 50 percent, and a free-standing, unenclosed patio, deck or gazebo counts zero.

Sec. 94-80(b)(4) sets the SF7-C4 historic district's cap on a sliding scale tied to lot size: 35 percent on lots up to 4,999 square feet, 30 percent on lots from 5,000 to 7,499 square feet, and 25 percent on lots of 7,500 square feet and larger. The city's other historic contexts, including SF14-C2, SF14-C3 and SF14-C5, apply the identical 35/30/25 percent sliding scale under sections 94-81 through 94-83. Sec. 94-85(d) lets city staff grant a limited lot-coverage exception where every structure on the lot is one story and none exceeds 16 feet in height, and Sec. 94-85(e) allows a similar exception for detached rear accessory structures of at least 300 square feet (250 square feet on lots under 5,000 square feet).

Outside these historic overlays, the base SF3, SF5, SF7, SF11 and SF14 residential districts under sections 94-72 through 94-74 set no maximum lot-coverage percentage at all; building footprint there is controlled only through minimum setbacks and the 30-foot height cap.
