Do you need a permit for a swimming pool in New York City?
It depends on the project. New York City exempts some swimming pools from a building permit and requires one for the rest1; the exemption's limit is 400 square feet, with the conditions in the city's wording below. Work that needs no building permit can still need zoning approval.
