New York County Registration Rules Rules (2026) — What You Need to Know

The implementing rules for Local Law 18 were published by the Mayor's Office of Special Enforcement on February 3, 2023, and took effect on March 6, 2023. They establish the detailed registration process, eligibility criteria, and ongoing compliance requirements for short-term rental hosts in New York City.

The prohibited buildings list is a central feature of the registration system. OSE maintains a list of buildings where short-term rentals are prohibited by law or by the building's own governing documents. This includes all NYCHA public housing, rent-regulated buildings, and any building whose owner or managing agent has notified OSE that short-term rentals are not permitted. As of mid-2025, over 14,000 property owners and managers had placed their buildings on the prohibited list, effectively removing those buildings from the short-term rental market.

The application process requires hosts to provide proof of permanent residency in the unit, documentation that the building's certificate of occupancy permits transient occupancy, and evidence that the building's lease or governing documents do not prohibit short-term rentals. OSE reviews each application individually. Approximately 40% of applications have been approved, with over 4,300 denied due to non-compliance with eligibility requirements.

Registered hosts must display their OSE registration number on every listing, advertisement, and platform profile. Hosts may not advertise an unlawful short stay even if they have a valid registration — for example, advertising a whole-apartment rental while the host is away would violate the law regardless of registration status. OSE monitors listings and has begun issuing warning notices and initiating a revocation pilot program for registered hosts who appear to be violating the terms of their registration.
