Yonkers accessory apartments may not be operated as short-term rentals (under 30 days) and may not be leased to non-relatives even on long-term terms. Chapter 43 limits occupancy to relatives of the lot owner or spouse. New York State Multiple Dwelling Law generally prohibits rentals of less than 30 days in Class A multiple dwellings statewide, and the 2024 statewide STR registry law adds tax-collection obligations through booking platforms.
Because Yonkers limits accessory apartment occupancy to relatives of the lot owner, traditional market-rate long-term leasing of an accessory unit is not permitted, and short-term rental of an accessory apartment is even more restricted. New York State Multiple Dwelling Law has long prohibited rentals of less than 30 consecutive days in Class A multiple dwellings unless the permanent occupant remains present. New York's statewide short-term rental registry, signed in late 2024 and effective in 2025, layers in statewide registration, host obligations, and platform tax collection (state and local occupancy/sales tax at approximately 8 to 9 percent in Westchester) for any legally operating short-term rental, but it does not override local zoning - it implements it. Westchester County maintains its own STR-related programs and may eventually adopt a county-administered registry. Long-term leasing of the principal dwelling while the owner moves into the accessory apartment is also not permitted because that flips the owner-occupancy requirement. Yonkers Code Enforcement actively monitors online listing platforms for unpermitted units, and citations carry civil penalties under Article XII.
Listing a Yonkers accessory apartment on Airbnb, Vrbo, Booking.com, or similar platforms violates Chapter 43's occupancy restrictions and may also violate the New York State Multiple Dwelling Law and the statewide STR registry law. Penalties include civil fines, orders to cease the listing, and revocation of the accessory apartment's certificate of occupancy. Booking platforms are required to remove non-compliant listings on notice and must remit occupancy tax collected.
