Subletting in NYC: What Every Buyer, Seller & Renter Should Know

New York City's real estate market is notoriously complex, and few topics are as rife with myths and confusion as subletting. For renters looking to cover a few months' rent while away, or for owners considering an apartment as an investment, understanding the rules is critical. Subletting in NYC is not a free-for-all; it’s governed by a mix of state laws, city regulations, and individual building policies that can vary dramatically.

This guide will break down the subletting landscape in NYC, from the general rules that apply to all apartments to the specific regulations for rent-stabilized units, co-ops, and condos.


A sublet occurs when a tenant (the "prime tenant") who has a lease with the landlord rents out their apartment, or a part of it, to another person (the "subtenant") for a period of time. The prime tenant remains on the original lease and is responsible for paying the rent to the landlord and for any damages caused by the subtenant.

Yes, subletting is legal in NYC, but it is not an unrestricted right. The process is tightly regulated by New York Real Property Law §226-b, which applies to tenants in buildings with four or more residential units. The key takeaway is this: you must get your landlord's consent before subletting.


General Rules for Rental Apartments

Before you can legally sublet your apartment, you must follow a specific procedure:

  1. Send a Formal Request: You must send a written request to your landlord via certified mail, return receipt requested, at least 30 days before the proposed sublease begins.

  2. Provide Required Information: Your request must include:

    • The reason for the sublet (e.g., temporary job relocation, travel).

    • The term of the sublease, including start and end dates.

    • The name, business and home address of the proposed subtenant.

    • A copy of the proposed sublease agreement.

    • Written consent from any co-tenant or guarantor on your lease.

  3. Landlord's Response: Your landlord has 30 days to respond to your request. They can either consent, request additional information, or deny the request.

    • If they consent, you can proceed with the sublet.

    • If they fail to respond within 30 days, their consent is considered to be granted by default.

    • If they deny the request, the denial must be reasonable. A landlord cannot "unreasonably withhold" consent. Valid reasons for denial include a subtenant's poor credit history, insufficient income, or a history of being sued for eviction. An unreasonable denial (e.g., based on race or religion) can be challenged in court.

The Golden Rule: The 30-Day Stay

A major legal pitfall for many is the law against short-term rentals. New York City's Multiple Dwelling Law makes it illegal to rent an entire apartment for less than 30 days in most buildings with three or more units, unless the prime tenant is present in the apartment throughout the subtenant's stay. This is why platforms like Airbnb are risky for full-apartment rentals. The penalties for illegal short-term subletting can be severe, including fines and eviction.


The general rules above are just the starting point. The specific regulations you face depend heavily on your type of housing.

Subletting in a Rent-Stabilized Apartment

If you live in a rent-stabilized apartment, you have specific rights and responsibilities.

  • Primary Residence Requirement: You must maintain the apartment as your primary residence. This means you must intend to return to the apartment after the sublease and use it as your main home. Using it as a pied-à-terre while you primarily reside elsewhere is a common cause for eviction.

  • Subletting Term Limits: The law limits you to subletting for a total of two years within any four-year period.

  • Rent Overcharge Rules: You are not allowed to overcharge your subtenant. The rent you charge them cannot exceed the legal regulated rent you pay, with one key exception:

    • Furnished Surcharge: You may charge a 10% surcharge on the rent if the apartment is being sublet "fully furnished."

Subletting in a Co-op

Co-ops are known for their strict rules, and subletting is where they are often the most restrictive. Unlike a rental, you are not a tenant but a shareholder in a corporation, and your ability to sublet is governed by the building’s proprietary lease and bylaws.

  • Board Approval is Mandatory: You must submit a full application for a prospective subtenant to the co-op board. The process is similar to a new buyer's application and can include financial documents, personal references, and even a formal interview.

  • Initial Residency Requirements: Most co-ops have a period of required owner-occupancy before you are allowed to sublet, often ranging from one to three years.

  • Term and Frequency Limits: It is very common for co-ops to cap the total time you can sublet (e.g., a maximum of two years out of every five).

  • Sublet Fees: Co-op boards almost always charge a sublet fee or a surcharge on your monthly maintenance, which can be a flat fee or a percentage (e.g., 20-30%) of the monthly maintenance.

Subletting in a Condo

Condos are generally more flexible than co-ops because owners hold individual deeds to their units. However, they are still subject to building bylaws.

  • Board Approval and Fees: While condo boards do not have the same power to outright reject a subtenant as a co-op board, they can and often do require an application process, background checks, and charge fees for subletting.

  • Rental Ratios: Condos are concerned with maintaining a low "rental ratio" (the percentage of units being rented vs. owner-occupied) to ensure the building remains "warrantable" for financing. If the ratio is too high, it can be difficult for buyers to get a mortgage, negatively impacting property values.


Tips & Takeaways

Whether you are a potential subtenant or a prime tenant, arming yourself with knowledge is your best defense.

  • Read Everything: As a prime tenant, read your lease and building bylaws carefully. As a subtenant, ask for a copy of the lease and ensure the sublet has been approved.

  • Get it in Writing: A signed sublease agreement is essential. It should outline the rent, security deposit, term, utility responsibilities, and any building rules.

  • Know the Market: Short-term, legal sublets (30+ days) can be a great way to find housing, but be vigilant for scams and confirm the legality of the arrangement.

  • Consult an Expert: The rules for subletting are complex and can have serious financial and legal consequences if not followed correctly.
