Local Law 18

Local Law 18 is New York City's Short-Term Rental Registration Law. It requires hosts to register with the Mayor's Office of Special Enforcement and Booking platforms to verify registrations before processing transactions. Adopted in January 2022, it entered its initial platform-focused enforcement phase in September 2023. The city also maintains a list of buildings where short-term rentals are prohibited by law, leases or occupancy agreements.

Registration operates alongside existing restrictions on residential accommodation. A host must be a permanent resident, remain in the same unit and accommodate no more than two paying guests. Building and tenancy restrictions still apply. Rentals lasting at least 30 consecutive days are exempt from registration. So are units in Class B buildings legally approved for short-term occupancy; that designation concerns permitted use, not the property's tax classification.
