Local Law 18/2022 ended absent-host rentals in Brooklyn. Registered STRs have no annual night cap, but each stay must be 1 to 29 nights with host on site. 30+ night stays are unregulated.
Unlike some US cities that impose a 90- or 180-day annual rental cap on short-term rentals, NYC uses a structural rather than numerical cap. Under Local Law 18 of 2022 and the Multiple Dwelling Law, any stay under 30 days in a Class A dwelling in Brooklyn must be owner-occupied with the host present and is limited to 2 guests. Once registered with the Mayor's Office of Special Enforcement, there is no ceiling on the number of nights per year the host may rent, provided each individual stay follows the rules. Before LL18 took effect in September 2023, NYC had effectively allowed unhosted rentals of up to 29 days; post-LL18 those rentals are prohibited. Stays of 30+ consecutive days are 'long-term rentals' and fall outside STR rules entirely — these have no night cap, no OSE registration requirement, and no 2-guest limit. Brooklyn listings on Airbnb dropped by roughly 80 percent in the year following LL18 implementation; most remaining compliant listings are hosted rooms in brownstones.
Operating under-30-day rental absent of host or exceeding 2 guests: OSE civil penalties of $1,000 to $5,000 per violation, per day. Platform liability of $1,500 per illegal booking.
