Local Law 18 primarily focuses on properties rented for periods of less than 30 days. If you’re a host or manager with listings that fall within this category, it’s essential to understand the implications of this law and what is expected of you.

Mandatory Registration: Hosts and property managers who have listings that fulfill the criteria outlined in Local Law 18 must register with the Office of Special Enforcement (OSE) through New York City's Short-Term Rental Registration Portal. This registration will set you back $145. Before submitting their request, hosts must also check the same site to see if their building is on a list of forbidden structures.

Displaying Registration Number: Following successful registration, the OSE will generate a one-of-a-kind registration number. This registration number must be clearly displayed on hosts' web listings on sites such as Airbnb, Booking.com, and Vrbo. This number acts as an indicator of legal compliance and provides potential visitors with certainty about the legitimacy of the establishment.

Airbnb has made efforts to comply with Local Law 18, and listings that do not have a registration number will no longer allow new bookings when the law goes into effect. Reservations made before September 5 will be honored for stays until December 1 and service costs will be refunded. Reservations at uncertified properties will be canceled and reimbursed after December 1.
