How to Add a Roommate to a Lease in New York

Thinking of adding a roommate to your apartment lease in New York? Understanding the legal process is essential to protect your rights — and your home. The rules for adding a roommate are set by New York State law, and following the right steps can prevent misunderstandings or legal troubles with your landlord. This guide breaks down the process in clear terms so you and your future roommate can co-sign with confidence.

Can You Add a Roommate to Your Lease in New York?

In New York, tenants have the right to take in a roommate, even if your lease doesn't mention them specifically. This right is protected under New York Real Property Law § 235-f, sometimes known as the "Roommate Law." However, there are rules about how and when to notify your landlord, limits to how many people can live in your apartment, and steps to properly update your rental agreement.

Adding a roommate the right way helps avoid conflicts, keeps you in good standing with your landlord, and ensures everyone is protected under the lease.

Steps to Add a Roommate to Your Lease in NY

Before you bring someone new into your home, it's important to follow these legal steps:

• Check your current lease: Review whether it allows, limits, or sets procedures for adding roommates.
• Notify the landlord in writing: New York law requires you to inform your landlord within 30 days after a roommate moves in. Written notice is crucial.
• Provide required information: Your notice should include the roommate’s name, and optionally, other basic info the landlord may reasonably request (age, occupation).
• Landlord credit/background check: The landlord may request to screen the new roommate. If so, make sure your roommate is prepared for this process.
• Update or sign a new lease: If the landlord agrees, you may receive an updated lease with the roommate’s name added as an "occupant" or "tenant." This step is not strictly required by law, but highly recommended for clarity and legal protection.

Official Forms and Templates

There is no standardized statewide form for "adding a roommate" to your lease in NY. However, a written notice fulfills the legal requirement. Here’s how you can handle it:

• Roommate Notice Letter (No official form number)
  When to use: Whenever you add a roommate, send your landlord a letter within 30 days.
  Example: "I am notifying you that Jane Doe has moved into Apartment 4B as my roommate as of March 1, 2024."
  More info: Page 12 of the NYS Tenant's Rights Guide
• New Lease Addendum (Landlord Provided)
  When to use: If your landlord wants to formally update the lease, they may provide a lease addendum or require all parties to sign a new lease.
  How it's used: All household members sign a new or amended lease. Always keep a copy.

Key Rules to Remember Under NY Law

• You must continue to follow all other lease terms if you take in a roommate.
• The "Roommate Law" does not protect guests who are not truly residents.
• There are limits: The total number of people in your rental must not exceed occupancy regulations (usually, no more than one unrelated roommate plus dependents). See official guidance: New York State HCR: Roommates and Occupancy Limits.
• If you are in rent-stabilized or rent-controlled housing, extra protections and requirements may apply. Review your rights via the NYS Division of Housing and Community Renewal.

In summary: You have the right to a roommate, but you must provide written notice to your landlord and follow all lease and occupancy rules.

What If My Landlord Says No or Tries to Evict Me?

If you notify your landlord as required and stay within the limits of the law, your landlord cannot legally evict you just for having a legal roommate. If you face retaliation (like threats or illegal eviction), you can get help from the New York State Division of Housing and Community Renewal or seek advice from local tenant support agencies.

How to Serve Written Notice: Sample Steps

• Write a simple letter addressed to your landlord or property manager.
• Include your name, address, unit number, your roommate’s name, and the date the roommate moved in.
• Deliver the notice via certified mail or email (if permitted in your lease) for proof.
• Keep a copy for your records.

Following these steps meets your legal obligations and helps prevent misunderstandings with your landlord.

FAQ: Roommates and Lease Rules in New York

1. Can my landlord refuse my new roommate?
   Under New York law, landlords generally cannot refuse a legal roommate unless the total occupancy exceeds housing codes or violates lease terms for good cause.
2. What happens if I don’t notify my landlord?
   Failure to notify your landlord may violate your lease and give grounds for eviction. Always send written notice and keep proof.
3. Do roommates have the same rights as tenants?
   A roommate added by notice does not automatically become a legal tenant with all lease rights unless specifically added to the lease by the landlord.
4. Does my rent go up when I add a roommate?
   Not automatically; but in some situations, your landlord may seek a new lease or addendum, possibly changing rent for new occupancy. Check your lease terms.
5. Who do I contact if my landlord tries to evict me for adding a legal roommate?
   You can seek help from the NY State Division of Housing and Community Renewal or a local tenant assistance group.
