Southampton Village, NY Building Setbacks & Zoning: Lot Coverage Limits (2026)

Section 116-11.2 sets one coverage formula for every one-family residence district (R-120, R-80, R-60, R-40, R-20, R-12.5 and R-7.5) and for the MF-20 Multifamily Residence District. Maximum lot coverage is 14% of the lot area of the lot plus 1,500 square feet. A hard ceiling follows: in no case in those districts can lot coverage exceed 30% of lot area. The formula measures coverage by main and accessory buildings and structures, so a garage, pool house or shed counts alongside the house.

Section 116-11B widens what is counted. The calculation of the percentage of lot coverage includes the lot areas covered by temporary structures and by open storage of more than an incidental transitory character. Coverage is a separate test from the yard table in § 116-11.1A, which also prints a greenspace minimum for each lot-area band: 35% for lots under 7,499 square feet, 40%, 45%, 50% and 55% for the next bands, then 60% and 65% for lots of 60,000 square feet and up.

Three related rules matter. A lot improved with an existing residence in a district where a new dwelling is not a permitted or special exception use, and whose area is reduced, becomes subject to the lot coverage, width, height and yard requirements of the R-20 Residence District under § 116-11D(6). Structures that exceed the district height limit under § 116-12A, such as spires or barns, cannot have a lot coverage in excess of 10% of the lot area. In the VB Village Business District, § 116-11.3C allows maximum coverage by main and accessory buildings and structures of 70%, with a maximum building footprint depth of 75 feet from the front property line on North Main Street, Main Street and Jobs Lane and 120 feet on all other streets.
