Is Airbnb Legal in NYC? Local Law 18 Guide for Hosts (2026)

Last updated: October 28, 2026

Is Airbnb legal in NYC? Only in a narrow form. A stay of under 30 days is legal when the host is registered with the Mayor's Office of Special Enforcement (OSE), is the permanent occupant of the home and stays in the same unit as the guests, with no more than two paying guests at a time (OSE FAQ for prospective hosts, last checked October 28, 2026). Renting out a whole apartment for a short stay while you're away isn't allowed. The fines are set in Local Law 18 of 2022: hosting without a registration carries up to $5,000 or three times the rental's revenue, whichever is less, per violation; a registered host who breaks the rules faces up to $5,000 per violation; and a booking platform faces up to $1,500 per transaction for an unregistered rental, or three times its fee if it can establish that fee.

This guide is informational, not legal advice.

New York adopted Local Law 18, the Short-Term Rental Registration Law, on January 9, 2022, and OSE began enforcing it with the booking platforms on September 5, 2023 (OSE registration page, last checked October 28, 2026). Stays of 30 consecutive days or more are outside the registration requirement. Here's what the law asks of hosts, what it costs to get it wrong, and what's still possible.

For a registered host, the two risks you can actually manage day to day are guest count and noise. Layla's All-in-One tracks both without a camera, with radar for headcount and a decibel reading for noise, for $299 once. More on that in the monitoring section below.

Is Airbnb Legal in NYC?

Yes, Airbnb is legal in New York City, but only in a narrow form. Hosts can legally list short-term rentals only if they register with the New York City Mayor's Office of Special Enforcement and are the permanent occupant of the home, staying in the same unit as their guests. Renting out an entire apartment for less than 30 days while you're away isn't allowed.

NYC Local Law 18 Explained

NYC Local Law 18 of 2022, also known as the Short-Term Rental Registration Law, is a strict regulatory framework introduced in New York City to control home-sharing activity and limit illegal short-term rentals. Its core purpose is to protect long-term housing supply and improve guest safety. The law also brought transparency to a market that had grown rapidly through online platforms.

The law was adopted on January 9, 2022, and OSE began enforcing it with the booking platforms on September 5, 2023. From that point, platforms had to check bookings against the city's verification system and stop processing unverified transactions.

A central part of the system is oversight by the New York City Mayor's Office of Special Enforcement. This office manages host registrations, verifies compliance, and enforces penalties for violations. Hosts must register with the OSE and receive approval before listing their property.

Key Requirements Under NYC Local Law 18

NYC Local Law 18 introduces strict conditions that every host in New York City must follow to legally operate short-term rentals. These rules are designed to ensure transparency, safety, and compliance across all listings.

Mandatory Registration

• All hosts must register with the New York City Mayor's Office of Special Enforcement
• Approved registration number must be obtained before listing
• The registration number must be included in every listing or advertisement for the unit, and a copy of the registration certificate (with an emergency contact number) plus an egress diagram must be posted inside the unit during each stay

Permanent Occupant Rule

• The host must be a natural person and the permanent occupant of the home
• Applicants must provide documents proving their identity and their occupancy status

Guest Limits

• No more than two paying guests at a time

Host Presence Requirement

• Hosts must remain physically present in the property during guest stays
• Entire-unit rentals without host presence are not allowed

Platform Verification Rules

• Booking platforms must verify a valid registration through the city's verification system before processing a booking
• Platforms may not process transactions for unregistered short-term rentals

These requirements form the core structure of NYC Local Law 18 and define what is legally permitted for short-term rental activity in the city.

Penalties for Non-Compliance

Local Law 18 sets penalties at three levels (Local Law 18 of 2022, checked October 28, 2026):

• Hosting without a registration: up to $5,000 or three times the rental's revenue, whichever is less, per violation.
• A registered host who breaks the rules: up to $5,000 per violation.
• A booking platform that processes a transaction for an unregistered rental: up to $1,500 per transaction, or three times its fee if it can establish that fee.

OSE also sends inspectors in response to 311 complaints and to investigate other evidence of illegal activity (OSE FAQ for registered hosts).

Building-code penalties can come on top. In its January 2026 enforcement bulletin, the Department of Buildings reported a $17,500 penalty on a Manhattan owner who rented out a basement apartment on Airbnb while not present, plus violations for the fire-safety systems that transient use requires (DOB enforcement bulletin, January 2026, checked October 28, 2026).

How Platforms Responded to Local Law 18

Major booking platforms like Airbnb and Vrbo quickly adapted to NYC Local Law 18 by integrating the city's verification system into their booking process. Before a listing can accept reservations, the platform must confirm that the host has a valid registration issued by the New York City Mayor's Office of Special Enforcement.

In its FY25 annual report on the law, OSE says booking sites are now actively preventing illegal listings from being activated. It counts about 3,000 active short-term rental registrations, against an estimated 60,000 illegal listings on major booking platforms in 2018 (OSE, checked October 28, 2026).

What Local Law 18 means for monitoring your listing

A legal New York listing is a shared home. You live there, you're present for the stay, and your guests have access to the whole unit, which OSE calls "maintaining a common household". So monitoring here isn't about watching an empty apartment from across town. It comes down to three jobs: keeping the stay at two paying guests, stopping noise before it becomes a complaint, and doing both without breaking Airbnb's own device rules.

The two-guest cap. You're present, but you're not awake all night or home every minute of the day. If two guests become four while you're out for dinner, you're the one over the limit. A camera-free occupancy sensor counts how many people are in the shared space, so you know before a neighbor or an inspector does.

Complaints. OSE says it sends inspectors in response to 311 complaints, as well as to investigate other evidence of illegal activity (OSE FAQ for registered hosts, last checked October 28, 2026). A noise monitor with a strict overnight limit tells you when the volume climbs, while there's still time to knock on a door down the hall instead of answering one.

No indoor cameras. Hosting in your own home doesn't change Airbnb's rule. Since April 30, 2024, Airbnb has banned security cameras and recording devices that monitor any part of a home's interior, even when they're switched off (Airbnb help article 3061). If you had a camera in the living room before you started hosting, it has to go.

What a compliant setup looks like. Airbnb allows noise decibel monitors inside the home if you disclose them and keep them out of bedrooms, bathrooms and sleeping areas. In a shared apartment the guest's room is a sleeping area, so the sensor belongs in the living room, kitchen or entry hall. Pick one that measures rather than records: a decibel level for noise and radar for headcount, with no audio and no image. We explain the rules device by device in are monitoring sensors allowed in an Airbnb, and compare the main devices in our guide to the best noise monitor for Airbnb.

Layla's All-in-One, $299 once covers all of it from one sensor: noise with quiet-hours limits, radar occupancy alerts when a stay goes over your guest limit, the AI party detector, and smoke detection for the guest who lights up by the window. If smoking is all you want to catch, Smoke & Air Quality, $99 once does that on its own. There's no subscription on either — a slow winter doesn't come with a monthly bill.

FAQs

Is Airbnb legal in NYC?

Yes, but only as a hosted stay. For stays under 30 days, the host must be registered with the Mayor's Office of Special Enforcement, be the permanent occupant of the home, stay in the same unit as the guests and host no more than two paying guests at a time. Renting an entire apartment short-term while you're away isn't allowed (OSE, last checked October 28, 2026).

What makes an Airbnb NYC legal?

Four things together: an approved OSE registration, the host living in the unit as its permanent occupant, the host's presence during the stay, and a maximum of two paying guests. Guests must have access to the whole unit, which OSE calls a common household. Stays of 30 consecutive days or more fall outside the registration requirement. This is general information, not legal advice.

What is Local Law 18?

Local Law 18 of 2022 is New York City's Short-Term Rental Registration Law, adopted January 9, 2022. It requires hosts to register with OSE and bars booking platforms from processing transactions for unregistered rentals. Unregistered hosting carries up to $5,000 or three times the revenue per violation, whichever is less; platforms face up to $1,500 per transaction, or three times their fee if they can establish it.

Can you Airbnb in NYC?

You can if you live in the home and stay there with your guests. That means registering with OSE, keeping to two paying guests at a time and giving them access to the whole unit. You can't legally rent out an entire home or apartment for under 30 days while you're away, except in buildings approved for short-term occupancy.

How does NYC short term rental registration work?

You apply online through OSE's Short-Term Rental Registration Portal. The application fee is $145 plus a small payment processing fee, paid when you apply and non-refundable. If you list on a booking platform, you also give your listing URL or identifier and the platform's name. Platforms check registration through the city's verification system before processing bookings (OSE, checked October 28, 2026).

NYC Local Law 18 has reshaped short-term rentals in New York City, but hosting is still possible for those who meet the legal requirements. Hosted stays by a registered permanent occupant, and bookings of 30 consecutive days or more, remain open to you. A compliance-first approach is the way to avoid fines and legal risk.
