Local Law 18 and the New York short-term rental crackdown, explained

What to take away

What Local Law 18 requires

Local Law 18 is New York City's short-term rental registration law, in force since 2023. It governs any rental of fewer than 30 days. The city's own guide to Local Law 18 sets out the rule in plain terms: register before you advertise.

Three obligations decide whether a listing is legal: register the unit with OSE, keep the host on site during every booked stay, and cap paying guests at two.

Fail any one and the listing is illegal, even while the platform keeps it online. That is the whole test. Everything below is detail hanging off it.

For a short-term rental management business, the consequence is blunt: the unit must be someone's primary residence. You cannot lease a two-bedroom in Midtown, furnish it, and run it as a hotel with a front desk that never sleeps.

Registration, eligibility and the Prohibited Buildings List

Registration runs through the Office of Special Enforcement, usually shortened to OSE. The agency's Registration Law - OSE page lists the application requirements, the documents a host submits, and the renewal cycle.

Applicants prove the unit is their primary residence, submit a diagram of the layout, and confirm the building permits short-term rentals. The city charges $145 per unit, and a registration runs for two years before it must be renewed. Operating without a number carries its own penalties.

The building can veto the whole plan. The Prohibited Buildings List - OSE names addresses where short-term rentals are barred outright. Landlords, co-op boards and condo associations add buildings to it, and once an address is listed, no host there can register.

That list is the quiet killer of New York short-term rental plans. A buyer can love the apartment, pass every other test, and still be locked out because the board opted out before the closing.

The list covers a large share of Manhattan's rental stock, particularly rent-regulated buildings and large multifamily properties. Check the address against it before advising anyone to buy. It is public and searchable.

Renewals deserve the same calendar treatment as a fire inspection. A lapsed registration puts the listing back into illegal territory the day it expires.

Owners weighing a purchase should work through the compliance checklist before signing anything.

Host presence and the two-guest limit

Presence is the requirement that reshapes the business model. The registered host must be in the unit while the guest stays. A host who leaves for the weekend and rents the whole apartment has broken the law, whatever the listing says.

Presence does not mean hovering. It means the host lives there and shares the space. Guests rent a room or rooms; the host keeps access to the unit.

Two paying guests is the ceiling. Family of the host can stay without counting, but a third paying guest pushes the rental into illegal territory.

Run the arithmetic on a three-bedroom that once slept eight. It now legally sleeps two paying guests. Revenue per unit falls, and the whole-home model that works in Miami or Nashville does not transfer.

The advertising counts too. A listing offering an entire apartment for four guests is evidence of a violation before anyone checks in, and OSE has used listing screenshots in enforcement actions.

Our guide to markets worth entering covers where the same capital goes further.

A host who rents one room in her own apartment, lives there, and caps guests at two can still operate. That is the legal core of the New York market now, and it is small.

Platform reporting duties and enforcement

Platforms carry their own obligations under the city's Reporting Law. Booking platforms must verify that a host is registered before publishing a short-term rental, and they must report activity to the city.

That reporting requirement is what makes enforcement cheap. The city does not have to hunt illegal listings one by one; the platforms hand over the data. A host who lists without a number is visible almost immediately.

OSE issues violations and fines. The platforms remove listings on their own. Repeat offenders face escalating penalties, and the city has pursued operators running multiple unregistered units.

Civil penalties run up to $5,000 for a first violation and up to $10,000 for each repeat, and each booked night can count separately. For a manager running several units, the exposure compounds.

Neighbors, co-op boards and landlords file complaints. A single complaint can trigger an inspection, and inspectors can request access to the unit.

Platforms have tightened their own rules in response. Airbnb blocks new unregistered listings in the city and requires existing hosts to certify compliance. Vrbo and Booking.com apply similar checks.

Treat platform correspondence as a compliance record. Keep registration confirmations, renewal receipts and guest records on file. If the city asks, the paperwork is the defense.

What happened to Manhattan and Brooklyn booking volumes

Enforcement changed the shape of the market. OSE began enforcing the registration rule on September 5, 2023. Manhattan and Brooklyn booking volumes fell after the registration regime took hold, with the steepest declines in entire-home listings, the category the law targets most directly.

Analysts tracking city short-term rental supply reported a large drop in active listings in both boroughs in the twelve months after that date. Entire-home listings, which dominated Manhattan, fell hardest. Private-room listings held up better because some of them can satisfy the host presence test.

Brooklyn followed a similar pattern, though its mix skews toward owner-occupied houses and smaller buildings. Parts of the borough kept more legal inventory than Manhattan's dense rental core.

Revenue per available night rose in the listings that survived, because supply shrank faster than demand. Travelers still want to stay in Manhattan; there are simply fewer legal units to book.

That gap pushed some demand into hotels and into New Jersey, where rules are looser. It also pushed some travelers toward longer hotel stays and traditional bed and breakfasts.

For owners, the lesson is that regulation, not demand, now sets the ceiling in New York. Our guide to short-term rental hiring tracks how these shifts are playing out across U.S. markets.

A worked example, and the records that keep it legal

The city publishes its own guidance for hosts, and it is worth reading in full: Tips for Hosting a Legal Short-term Rental - OSE. It covers registration, presence, guest limits and record keeping in plain terms.

A host owns and lives in a two-bedroom co-op in Brooklyn. The building is not on the Prohibited Buildings List. She registers the unit, rents one bedroom to two guests, and stays home during the stay. That is legal.

If she leaves for a week and rents both bedrooms to four guests, it is not.

The checklist that keeps her on the right side of the law:

Managers should watch the money side too. Rental income flows to Schedule E, and platforms issue Form 1099-K for gross receipts. New York State and city tax obligations apply on top of federal ones.

A licensed CPA or tax attorney is the right authority for how those land on a specific owner, and IRS Publication 527 covers residential rental income.

The regulatory picture keeps moving. Our licensing and compliance guide covers the wider U.S. permit system, and the short-term rental expansion piece covers adding units in cities with clearer rules.

If New York is the plan, budget for legal review. A local attorney who knows OSE practice costs less than a violation, and the rules reward hosts who document everything.

Common questions

Can I rent my whole apartment on Airbnb in New York City?

Only if you stay in it during the guest's visit and limit paying guests to two. Renting an empty whole apartment for fewer than 30 days is illegal under Local Law 18.

How do I know if my building is on the Prohibited Buildings List?

The list is public and searchable through the Office of Special Enforcement. Check the address before you buy, list or sign a management agreement. A building on the list blocks every host inside it, regardless of how well the unit otherwise qualifies.

What happens if I list without registering?

Platforms must verify registration numbers, so unregistered listings get removed. The city can also issue fines, and each booked night can count as a separate violation. Repeat cases against multi-unit operators have drawn escalating penalties.

Is a short-term rental management business still viable in New York?

Yes, but only around owner-occupied units that meet the host presence and two-guest rules. Managers who want the whole-home model should look at other markets.
