Oyster Bay, NY Building Setbacks & Zoning: Structure Height Limits (2026)

1 sets the baseline rule: no structure shall exceed the maximum permitted building height for the district in which it is located, except as the height provisions themselves allow. 1 permits spires, cupolas, belfries, parapet walls, chimneys, solar panels, flagpoles, antennas and similar rooftop features to rise up to 10 feet above the roof they sit on, provided they cover no more than 10% of the roof's horizontal area; that 10% roof-coverage cap does not apply to solar panels specifically. 2 lets public and semi-public buildings such as schools and places of worship reach up to 45 feet, but only if every required yard is widened by at least three feet for each foot of height above 28 feet, a direct height-to-setback tradeoff.

3 allows the same category of rooftop features up to 15 feet above the roof, again capped at 10% roof coverage except for solar panels. 4 separately addresses mechanical equipment, elevator or stair bulkheads and water towers: they may go on the roof only if the Department of Planning and Development finds it necessary, must be enclosed or screened, set back at least 10 feet from all roof edges (20 feet if within 100 feet of residentially used property), and are capped at 12 feet in height and 20% of the roof's total area; where the roof cannot meet that setback, the equipment must still stay at least five feet from any edge. 6:1 in the rear yard.
