Local Law 18 is New York City's short-term rental registration law, enforced since 5 September 2023: any host offering a stay of fewer than 30 consecutive nights must be registered with the Mayor's Office of Special Enforcement, must live in the unit and be present during the stay, may host no more than two paying guests, and must give guests access to the whole home. Booking platforms cannot process payment for an unregistered listing. In practice it ended whole-apartment Airbnb in New York.
The detail
The law did not create the underlying rules; it made them enforceable. New York's Multiple Dwelling Law has prohibited renting a whole apartment in a building of three or more units for under 30 days since 2010, and the host-present, two-guest rule dates from the same statute. What Local Law 18 added was a registration requirement, a public list of registered units, and a duty on Airbnb, Vrbo and Booking.com to verify a registration number before taking payment. Enforcement began on 5 September 2023, after a registration window that opened in March 2023.
The effect was immediate. Short-stay listings across the city fell from more than 20,000 to a few thousand within months, and most of those that remain are rooms in the host's own home. Registration is refused where the building is on the prohibited-buildings list that landlords can join, where the unit is rent-stabilised, or where the host does not occupy the unit as a primary residence. Hosts who let without registering face civil penalties that escalate with repeat violations, and platforms face a penalty per unlawful transaction, which is why the platforms police it themselves.
For an investor the conclusion is short. There is no legal way to run a whole apartment on nightly lets in New York City. The two models that survive are the host-present room, which is a lifestyle income rather than an investment, and furnished stays of 30 nights or more — the 'mid-term' market of relocations, medical stays and corporate housing, which is exempt from the law but rents at a discount to nightly rates and carries longer voids between guests. Class B buildings such as hotels and legal SROs are the only exemption for shorter stays, and they are not something an individual buys into.
The numbers that matter
Where this stops holding
This is New York City's five boroughs only — Westchester, Long Island and the Hudson Valley have their own, mostly lighter, rules, and Jersey City across the river runs a separate permit regime. Penalty amounts, the registration fee and the exact building lists are set by the city's rules and are revised; the Office of Special Enforcement's own pages are the authority on the current figures. The mid-term market this leaves behind is real but thinner and slower than the nightly market it replaced.
