Running an Airbnb in NYC is legal only under narrow conditions. To answer the question directly: Airbnb is legal in NYC when you live in the unit as your primary residence, stay physically present for the entire guest stay, host no more than two paying guests at a time, and hold an active registration number from the Mayor’s Office of Special Enforcement. Rent out an empty apartment for a weekend and you are breaking the law. As of June 30, 2025, only 2,952 short-term rental registrations were active across all five boroughs,1NYC.gov. Short-Term Rental Registration Report FY25 down from an estimated 30,000 to 40,000 Airbnb listings before enforcement began.
The Host-Presence Rule
The framework rests on the New York State Multiple Dwelling Law. Any building housing three or more independent families counts as a “multiple dwelling,” which covers the vast majority of NYC apartment buildings. A Class A multiple dwelling is designated for permanent residence, meaning occupancy by the same person or family for 30 consecutive days or more.2New York State Senate. New York Multiple Dwelling Law 4 – Definitions
That definition is what makes renting out an entire Class A apartment for fewer than 30 days illegal. The apartment is zoned as somebody’s home, not a hotel room. For a short stay to be legal, the permanent resident must remain in the apartment for the whole visit. Handing over the keys and leaving town is not an option.
Two more limits apply. No more than two paying guests at a time. And guests must have free access to the entire apartment, including all exits, so keyed bedroom locks that carve the unit into hotel-style rooms violate the law even if you are home.
One- and two-family houses sit outside the Multiple Dwelling Law, but the NYC Housing Maintenance Code applies the same 30-day threshold to them. Shorter stays are only allowed when the permanent occupant is present and hosting guests or lawful boarders.3NYC.gov. Title 27 – Chapter 2 Housing Maintenance Code Owning a brownstone does not exempt you from the presence requirement or the registration requirement below.
Registration With the Office of Special Enforcement
Local Law 18, the Short-Term Rental Registration Law, took effect for enforcement in September 2023. Every host offering a rental for fewer than 30 days must register with the Mayor’s Office of Special Enforcement (OSE) and receive an approved registration number before listing the property.4NYC.gov. Registration Law – OSE
The law leans hard on platforms. Airbnb, Vrbo, Booking.com, and similar services are prohibited from processing payments for any listing that lacks a valid registration number.4NYC.gov. Registration Law – OSE Even if you manage to post a listing without registering, the platform is supposed to block the booking before money changes hands.
Before you apply, check the Prohibited Buildings List. Building owners, co-op boards, and condo associations can add their property to that list, which automatically disqualifies every unit in the building from receiving a registration.4NYC.gov. Registration Law – OSE Most NYC co-op boards already prohibit subletting, so the list eliminates a large share of the housing stock before an application even begins.
What the Application Requires
Registration goes through the city’s online Short-Term Rental Registration Portal. You will need:
- A government-issued photo ID.
- Proof the unit is your primary residence, such as a utility bill or tax document.
- A floor plan showing all rooms, guest sleeping areas, and emergency exits.
- If you rent, a copy of your lease plus a certification that it does not prohibit short-term rentals.
- Information on every permanent resident of the dwelling unit.
The fee is $145 plus a small processing surcharge, and it is non-refundable whether OSE approves or denies your application.5NYC.gov. FAQ for Prospective Hosts – OSE OSE reviews the application against the Multiple Dwelling Law requirements, checks the Prohibited Buildings List, and verifies your documents. Status updates come through the portal.
What You Risk If You Skip Any of This
Operating an unregistered short-term rental carries a civil penalty of up to $5,000 per violation, or three times the revenue the rental generated, whichever is lower. Advertising a rental without your registration number is a separate violation: $100 for a first offense, $500 for a second, and $1,000 for a third or subsequent one. Default penalties for failing to respond can reach up to $5,000.6NYC.gov. Final Rules Governing Registration and Requirements for Short-Term Rentals These fines can fall on the property owner even if a tenant is the one running the illegal rental.
Platforms face up to $1,500 per booking for processing an unregistered transaction.6NYC.gov. Final Rules Governing Registration and Requirements for Short-Term Rentals That is why the major platforms now block unregistered listings on their own.
Your Lease, Co-op, or Mortgage Can Still Say No
City registration is only one layer of permission. If you rent, your lease almost certainly addresses subletting, and many NYC leases explicitly forbid short-term rentals. The registration application requires you to certify that your lease allows the activity.4NYC.gov. Registration Law – OSE Falsifying that certification is both a registration violation and potential grounds for eviction.
Homeowners have their own layer. FHA-insured loans require the property to be owner-occupied as a primary residence, and the appraisal guidelines specifically exclude properties rented for transient or hotel-like purposes from certain calculations.7Department of Housing and Urban Development. Revisions to Rental Income Policies, Property Eligibility, and Appraisal Protocols for Accessory Dwelling Units (Mortgagee Letter 2023-17) Conventional mortgages often carry similar occupancy covenants. Running an Airbnb in violation of your mortgage terms can technically trigger a default, though enforcement is uneven.
Taxes on the Income
Short-term rental income is taxable at the federal, state, and city levels. The IRS treats it as reportable income, with one narrow exception: if you rent your home for fewer than 15 days during the entire year, you do not need to report the income and cannot deduct related expenses.8Internal Revenue Service. Topic No. 415, Renting Residential and Vacation Property Once you cross the 14-day threshold, every dollar becomes reportable, whether or not the platform sends you a Form 1099-K.9Internal Revenue Service. Understanding Your Form 1099-K
New York State income tax applies to the same earnings, and NYC residents owe city income tax on top of that. Occupancy is also subject to state and local sales tax plus a New York City unit fee of $1.50 per unit per day.10Tax.NY.gov. Hotel and Short-Term Rental Unit Occupancy Platforms generally collect and remit sales tax on hosts’ behalf, but confirm with your platform rather than assume.
Insurance Usually Will Not Cover You
Standard homeowners and renters policies are written for owner-occupied residences, not commercial hospitality, and most exclude short-term rental activity outright. If a guest is injured, starts a fire, or damages a neighbor’s property, a regular policy will likely deny the claim once the insurer learns the unit was rented. Airbnb’s Host Protection Insurance provides some coverage but has exclusions and caps. Hosts who plan to rent regularly should look into specialized short-term rental insurance combining property, liability, and lost-income coverage.
What This Adds Up To
For a prospective host, the qualifying conditions stack up quickly. You need to live in the unit full-time, stay home during every guest stay, cap guests at two, register with OSE and pay the $145 fee, confirm your building is not on the Prohibited Buildings List, get past any lease or mortgage restrictions, handle federal, state, and city taxes, and carry insurance that actually covers the use. Each condition narrows the pool, which is why fewer than 3,000 registrations are active citywide.
For a visitor, the effect on the market is direct: fewer legal listings, higher nightly rates, and stays that resemble hosted rooms rather than empty apartments. If a listing offers you the whole place for a weekend with no host on site, it is almost certainly operating outside the law.
