Weston, FL Building Setbacks & Zoning: Lot Coverage Limits (2026)

Weston's Accessory Use Regulations chapter sets two related coverage limits for single-family lots. Section 124.36(G) caps the maximum impervious area, driveways, patios, pool decks, structures, and other hardscape, at 60 percent of a single-family residential lot; the remaining 40 percent must stay pervious for stormwater to infiltrate rather than run off. Section 124.36(F) separately limits enclosed accessory uses, listed as including cabanas, mother-in-law quarters, patios, storage sheds, and recreational structures, to no more than 25 percent of the floor space occupied by the main permitted use, and requires the accessory structure to match the main structure's roof profile, materials, color, and architectural style.

A parallel, district-specific coverage limit applies in the Agricultural Estate (AE) zoning district: section 124.47(A)(1)(c)4 caps plot coverage there at 25 percent of the plot area for all combined main and accessory buildings and structures, a tighter limit reflecting the district's larger minimum lot sizes and rural character. These coverage rules interact with the setback and encroachment standards in the same title; an over-the-impervious-limit driveway extension or an oversized shed cannot be brought into compliance by shifting it into a setback, since 124.36(H) requires accessory buildings to meet the same setbacks as principal buildings except for narrow reductions on rear-half accessory structures.

A property owner adding a pool deck, a shed, or additional paving must confirm the running total against the 60 percent impervious cap before a building permit will be approved.
