Is Airbnb Legal in NYC? Local Law 18, Explained

New York has always had a complicated relationship with its guests. We adore you, we feed you, we point you toward the good bagels — and then, in 2023, we quietly made it almost impossible for you to rent an apartment here for the weekend. If you've searched for a short-term rental in the city lately and wondered where everything went, this is the story: what Local Law 18 actually says, what it means for your stay, and how savvy travelers are still living like locals — legally, comfortably and without a single gray area.

The short answer

For stays under 30 days, renting an entire apartment in New York City is, in most cases, illegal — for the host. Since September 5, 2023, short-term rentals must be registered with the city, the host must be physically present in the home during your stay, and no more than two guests may stay at a time. An entire apartment to yourself for a week? With very few exceptions, that listing cannot legally exist.

For stays of 30 days or more, none of this applies. Furnished monthly and extended-stay rentals are fully legal, always have been, and remain the way New Yorkers themselves land in the city between homes, assignments and seasons. This is the corner of the market where Seasonal lives — every residence in our collection hosts stays of 30+ days, fully compliant, no asterisks.

What Local Law 18 actually says

Local Law 18 — formally the Short-Term Rental Registration Law, passed in 2022

and enforced from September 5, 2023 — didn't technically make anything newly illegal. New York's Multiple Dwelling Law had long prohibited renting most apartments for under 30 days unless the permanent occupant stayed in residence. What LL18 changed was enforcement — with three moves:

Registration. Any host offering a stay under 30 days must register with the Mayor's Office of Special Enforcement (OSE). Registration requires that the host be the permanent occupant, remain present throughout the stay, host no more than two guests, and give those guests free run of the home — no locked internal doors between you and your host. Entire buildings (many co-ops, condos and rental buildings) sit on a prohibited-buildings list and cannot register at all.

Platform accountability. The genuinely clever part: booking platforms — Airbnb, Vrbo, Booking.com — are barred from processing payments for unregistered short-term listings, with fines per illegal transaction. The city didn't chase thousands of hosts; it switched off the cash register. Within weeks of enforcement, the great majority of entire-home short-term listings in the five boroughs disappeared.

The 30-day line. Everything above applies only to stays under 30 days. At 30 days and beyond, a furnished rental is simply a rental — an arrangement as old as the city, requiring no registration and no host on the sofa.

What this means for you, the guest

Here's the part travel forums tend to bury: the law targets hosts and platforms, not guests. You won't be fined for sleeping in the wrong apartment. But you carry the practical risk — bookings cancelled when listings are purged, "hotel-style" workarounds that turn out to be someone's spare room with your host in it, or the memorable experience of arriving to a building whose doorman has firm opinions about your suitcase. When a short-stay entire-apartment listing in NYC looks too good to be true in 2026, it very nearly always is.

So your legal options for a New York stay are, in essence, three: a hotel room; a registered short-term rental (a spare bedroom, your host at home, two guests maximum); or — if your stay is, or can become, 30 days or longer — a furnished apartment of your own.

Why the 30-day stay is the one worth wanting

Some of our favorite guests arrived at 30 days by accident — the two-week trip that stretched, the renovation that ran long, the "let's just try a month" that became a season. They tend to discover what New Yorkers already know: a month is when the city starts giving back. You get a home, not a room — a kitchen that earns its keep, a real dining table, a washer-dryer, a block whose rhythms become yours: the dry cleaner learns your name, the coffee place starts your order at the door. Per night, a well-run furnished monthly rental typically lands meaningfully below a comparable hotel suite once you're past the 30-day line — with several hundred more square feet to show for it.

And it's the difference between visiting New York and briefly being a New Yorker — as stressed, humbled and delighted as the rest of us.

Who lands here

The 30+ day guest is rarely a tourist. It's the family relocating and unwilling to choose a forever-neighborhood from a hotel room; the executive on a project measured in quarters — the world corporate housing was built for; the household mid-renovation; the couple giving the city a proper audition; the diplomat posted near the UN. For each, LL18 didn't close a door — it clarified which door was theirs all along.

How Seasonal fits

Everything in the Seasonal collection is built for exactly this stay: private, fully furnished residences in New York City — from a full-floor home in the Diplomatic District like The Diplomat #3 to a jewel box on the prettiest corner of the West Village — hosted for 30 days or more, fully compliant with city and state law. No registration questions, no host on the couch, no gray. Designed, furnished and serviced so that a month in New York feels less like a long trip and more like the good version of moving in: groceries before you land, housekeeping on your rhythm, a team on call. The service of a hotel. The comfort of a home.
