New York City has the most restrictive short-term rental regulations of any major American city. Local Law 18, which took full effect on September 5, 2023, fundamentally changed what is legal in the five boroughs. If you are a host in New York or thinking about becoming one, you need to understand exactly what these rules require, because the consequences of getting it wrong are expensive and the city enforces aggressively.
I have been following New York City housing and rental regulations for decades. The city spent years watching housing stock converted to de facto hotel rooms while long-term residents got squeezed out of their own neighborhoods. Local Law 18 was the city's response, and it is a sweeping law. Understanding it is not optional for anyone who wants to operate legally in New York.
What Local Law 18 Actually Requires
Local Law 18 established a city-wide registration system for short-term rentals administered by the Mayor's Office of Special Enforcement (OSE). Every host must hold a valid OSE registration before accepting any short-term booking. The law applies to rentals of fewer than 30 consecutive days.
But the registration is only part of the picture. The law also imposed two operational requirements that are just as significant as the registration itself.
First, the host must be physically present in the dwelling during every guest stay. You cannot leave your apartment, go away for the weekend, and have guests staying in your home while you are gone. You must be there. This means whole-apartment, no-host-present rentals are flatly illegal under Local Law 18, regardless of whether you have a registration.
Second, maximum occupancy for short-term guests is two people. You cannot rent to groups of three, four, or more guests for stays under 30 days, even if your apartment can comfortably accommodate more people.
Taken together, these rules effectively ended the traditional Airbnb model in New York City: the kind where a host posts their entire apartment, leaves for a trip, and rents it out to a group of tourists. That model is illegal. What remains legal is renting a room or rooms in your home while you are present, to no more than two guests at a time.
How OSE Registration Works
The application is submitted through the Mayor's Office of Special Enforcement at nyc.gov/site/specialenforcement/short-term-rentals. You will need to provide documentation proving the property is your primary residence. Acceptable proof includes a New York State driver's license or non-driver ID showing the property address, utility bills, a lease or mortgage document, and voter registration records.
OSE reviews the application and, if everything checks out, issues a registration number. This number must appear in your listing on Airbnb, VRBO, or any other platform you use. Platforms are legally required under Local Law 18 to verify registration numbers before allowing bookings. Listings without a valid number cannot be booked through the major platforms.
Registration is tied to the specific address and the specific host. You cannot transfer a registration to a new occupant or use one registration for multiple units, even in the same building.
The Fines: Why This Matters Financially
OSE actively enforces Local Law 18. The fine structure is meaningful. For a first violation, hosts face fines of up to $1,000. For a second violation, fines go up to $5,000. For each subsequent violation after that, the penalty can be up to $5,000 per occurrence. For a particularly active unlicensed operator, that can add up to real money very quickly.
Platforms that process bookings for unregistered listings face fines of $1,500 per booking. That creates a strong financial incentive for platforms to actively delist non-compliant listings, which they have done. After Local Law 18 enforcement began, Airbnb saw listings in New York City drop by roughly 80 percent compared to pre-law levels. Most of those listings were whole-unit rentals that simply could not comply with the host presence requirement.
Building Rules and Lease Restrictions
Getting an OSE registration does not override your building's own rules. Many New York City co-ops and some condominiums have bylaws that expressly prohibit short-term rentals regardless of what the city permits. Many leases include clauses that forbid subletting or operating a commercial lodging business from the unit.
If your building's rules or your lease prohibit short-term rentals, operating one even with an OSE registration can result in eviction proceedings or significant financial penalties from your building. Check your governing documents and lease carefully before applying for a registration. If you are in a co-op, get a written confirmation from the board. Verbal approvals are not reliable protection.
Hotels, MDUs and Building Type Distinctions
Local Law 18 applies to residential dwellings. Buildings classified as hotels are regulated differently. For hosts in mixed-use or commercial buildings, the classification of your unit matters. If you are unsure whether your unit falls under Local Law 18's scope, the OSE website has guidance and you can contact OSE directly with questions.
Multiple Dwelling Law provisions also interact with Local Law 18 in specific building types. Buildings with three or more units are subject to certain occupancy and safety rules that predate Local Law 18 and work alongside it.
Practical Reality for New York City Hosts in 2026
The practical effect of Local Law 18 is that legitimate short-term hosting in New York City means you are essentially a room-sharer. You live in your home, you rent one or two rooms to guests while you are there, and you have a valid OSE registration number displayed in your listing. That is the legal model.
Some hosts do this successfully and profitably. If you are in a desirable neighborhood with a large apartment, renting rooms to two guests at a time while you occupy the rest of the unit is a real income source. The key is strict compliance: be present, limit to two guests, maintain your registration, and keep your listing updated.
Tracking your OSE registration renewal date and maintaining documentation that you are in compliance with the host presence requirement is something that should be on your compliance calendar year-round.
