Southampton Village, NY Accessory Structures: Shed & Carport Rules (2026)

Section 116-9A(1) of the Southampton Village Code sets the general provisions for accessory buildings in all districts. A building detached from the main building, or connected to it only by an open breezeway-type structure, has to be not less than five feet from the main building. The size cap depends on the district's required lot area: 520 square feet where the district requires 20,000 or less square feet of lot area, and 800 square feet where it requires more than 20,000. The building's area is included in the computation of lot coverage. Height is capped at 16 feet, measured from the natural grade of the lot before the placement of any material on the parcel to the highest point of the building.

Use limits follow. No accessory building can be constructed with a cellar or below-grade story, and no heating can be installed in any part of it. Under (f), no part of it can be designed or used for sleeping purposes and no cooking facilities can be placed in it. A building designated as a poolhouse has to be located no further than 25 feet from the swimming pool it serves.

Placement is covered by § 116-9A(3): accessory buildings and structures, including private garages, cannot be placed within a front yard, a required side yard or the total required side yards for a principal building. That text was amended 8-10-2023 by L.L. No. 14-2023. Section 116-9A(9) addresses connections: a building joined to another by an unenclosed breezeway-type structure is a separate building, and one joined by an enclosed breezeway is a separate building if the breezeway's width is less than 1/2 of its length. Section 116-9A(2) treats the walls of a private garage built as a structural part of the main building as walls of the main building for the front, rear and side yard regulations.

Permits come from Chapter A119. Section A119-1A requires a separate building permit from the Building Inspector for each building or structure, other than ordinary repairs that are not structural. Section A119-2 lists a fee of 1.5% of the estimated cost of construction and materials for other accessory structures.
