Minimum Apartment Size NYC
New York City does not have general requirements for minimum apartment sizes except in certain specific cases although there are requirements for bedrooms and living spaces. A few zoning districts do have a minimum dwelling unit sizes, as well affordable housing apartments have minimum requirements.
Previously NYC had minimum apartment sizes in the zoning code. Buildings developed under Quality Housing Regulations had a minimum apartment size of 400 square feet. This requirement was removed from the zoning code (in 2016) allowing developers to build new buildings or alter buildings with micro units under 400 square feet. For market rate buildings there is no general minimum unit size but the units must fulfill all other code requirements. There are certain instances where there are minimum unit sizes are applicable these are: housing for affordable residences for seniors, affordable housing, and residential developments in certain zoning districts.
Micro Apartment Requirements:
Micro apartments are full apartments just compact ones. The still require a kitchen and a 3 piece bathroom. If the micro unit is on the first floor of a walk up or on any floor in an elevator building it will need to be handicapped accessible complying with ADA standards.
The NYC Building Code requires all apartments or dwelling units to have at least one room with a minimum square footage of 150 square feet. The typical minimum bedroom size is 80 square feet. In the case of a studio or one room apartment the 80 square foot rule would not apply. You would need the room to be 150 square feet. This does not count closets, the bathroom or a kitchen / kitchenette. Therefor the minimum micro unit square footage would be 150 square feet plus the kitchen, bathroom, and closets square footage.
