NYC Roommate Law Explained: Your Rights to Share Your Apartment

TL;DR – New York's "Roommate Law" (Real Property Law § 235-f) gives you the right to live with a roommate, even if your lease explicitly forbids it. If you are the only tenant on the lease, you can bring in one unrelated roommate and their dependent children without asking for permission—you just need to notify your landlord.

The Myth of the "No Roommates" Lease

It is one of the most common stressors for NYC renters: You find an apartment you love, but the rent is just slightly out of reach. Or perhaps you are already in a lease, but a breakup or job change has made the rent a burden. The solution seems obvious—get a roommate.

But then you look at your lease.

"Occupancy is limited to the Tenant named herein and their immediate family. No other persons shall occupy the premises."

This clause appears in thousands of standard NYC leases. It looks official, legal, and binding. It scares tenants into struggling with rent alone or moving out entirely.

Here is the truth: That clause is likely unenforceable.

In New York State, the "Roommate Law" (Real Property Law § 235-f) overrides restrictive lease clauses. The law recognizes that in a city with some of the highest rents in the world, sharing an apartment is often a necessity, not a luxury. Landlords cannot force you to live alone, nor can they evict you simply for bringing in a roommate—provided you follow the specific rules outlined in the statute.

This guide will walk you through exactly what your rights are, how the rules differ depending on who is on the lease, and the correct legal process for notifying your landlord.

Scenario A: You Are the Only Tenant on the Lease

This is the most powerful part of the Roommate Law. If you are the only person named on the lease, your rights are broad and explicitly protected.

Under the law, you are entitled to share your apartment with:

Your immediate family members, AND
One additional unrelated occupant (a roommate), AND
The dependent children of that occupant.

The "Permission" Misconception

Many tenants believe they need to ask their landlord for permission to bring in a roommate. This is false.

If you meet the criteria (you are the sole leaseholder and this is your primary residence), you do not need to request permission. You have a statutory right to have a roommate. The landlord cannot "deny" your request because you aren't making a request—you are exercising a right.

However, you do have a responsibility to inform them (more on that in the Notification section below).

What If My Lease Says "No"?

The law specifically states:

"Any provision of a lease or rental agreement purporting to waive a provision of this section is null and void."

This means if your landlord made you sign a lease saying "No Roommates," that specific sentence is legally worthless. They cannot evict you for violating a clause that violates state law.

Scenario B: Two or More Tenants on the Lease

If you signed the lease with a friend, partner, or spouse (meaning there are two or more names on the legal document), the rules are stricter.

The law is designed to prevent overcrowding. It essentially sets a cap on the number of adults in the apartment equal to the number of tenants named on the lease.

The Replacement Rule

If there are two tenants on the lease (let's call them Tenant A and Tenant B), you generally cannot add a third unrelated adult.

However, if Tenant B moves out but stays on the lease (or leaves the lease entirely), Tenant A has the right to replace them with a new roommate.

The formula works like this:

Total Occupants (Tenants + Roommates) ≤ Number of Tenants on the Lease

(Note: This count generally excludes the occupants' dependent children.)

Example Scenarios

Important Caveat for Couples

If you and your partner are both on the lease, you occupy two "slots." You cannot bring in a third roommate under this law. However, if only you are on the lease, your partner counts as your "one additional occupant" (unless you are married, in which case they count as immediate family, and you still get your "one additional occupant" slot).

The Mandatory Notification Process

While you don't need permission, you must provide notification. This is where many tenants trip up and give their landlord an opening to cause trouble.

The 30-Day Rule

The law requires you to inform your landlord of the new roommate's name within 30 days of them moving in. Alternatively, if the landlord asks you for the information, you must provide it within 30 days of the request.

How to Notify Your Landlord (Template)

Do not ask "Can I?" or "Is it okay?". Be professional, polite, and declarative. Send this via certified mail or a traceable email so you have proof of delivery.

Subject: Notification of Additional Occupant - Apt [Number]

Dear [Landlord Name],

I am writing to inform you that pursuant to New York Real Property Law § 235-f, I have an additional occupant residing with me in my apartment:

Name: [Roommate's Full Name] Move-in Date: [Date]

This notification is provided in compliance with the 30-day notice requirement of the statute. My apartment continues to be my primary residence.

Sincerely, [Your Name]

Can the Landlord Reject Them?

Generally, no. The landlord cannot screen your roommate for credit score, income, or background unless you are asking to add them to the lease formally (which you are not—they are just an occupant).

Exceptions where a landlord CAN object:

Overcrowding: If adding a person violates city safety codes (e.g., less than 80 square feet of living space per person).
Bad Actor: If the roommate has been a nuisance or poses a danger to the building (though the landlord would have to prove this).

Money Matters: Charging Your Roommate

Before you post that ad on Craigslist or Spareroom, you need to know the rules about rent. These differ significantly depending on whether your apartment is Market Rate or Rent Stabilized.

Rent Stabilized Apartments: The 50/50 Rule

If you live in a Rent Stabilized unit, the law is incredibly strict to prevent you from becoming a "profiteering" landlord yourself.

You cannot charge a roommate more than their "proportional share" of the rent.

If there are 2 people (You + Roommate): You can charge max 50% of the legal rent.
If there are 3 people (You + Partner + Roommate): You can charge max 33%.

❌ The "Furnished" Loophole: Unlike subletting (where you can add 10% for furniture), there is no furniture surcharge allowed for roommates in stabilized apartments.

🚩 The Risk: If you overcharge a roommate in a stabilized apartment, they can file a complaint with the DHCR. You could be forced to refund the overcharge plus treble (triple) damages, and in severe cases, you could face eviction for profiteering.

Market Rate Apartments

In a market-rate apartment, the "proportional share" rule does not explicitly apply in the same statutory way. Generally, roommates agree to split rent based on room size, amenities, or simply what is agreed upon.

However, caution is advised. If you are charging a roommate more than the total rent (i.e., you are living for free and making a profit), your landlord could argue you are engaging in a commercial enterprise, which likely violates your residential lease.

Distinguishing "Roommates" from "Sublets"

It is crucial not to confuse the Roommate Law with the Right to Sublet (Real Property Law § 226-b). They are two different legal concepts with different rules.

Feature	Roommate Law (§ 235-f)	Right to Sublet (§ 226-b)
Your Status	You continue to live in the apartment	You move out temporarily
Landlord Permission	Not Required (Just notification)	Required (Can't be unreasonably denied)
Time Limit	None (as long as you stay)	2 years out of any 4-year period
Occupant Rights	No tenancy rights (licensee)	Temporary exclusive possession

Key Takeaway: If you are physically present in the apartment, you have a Roommate. If you are leaving for the summer and someone else is taking your place, you are Subletting. Do not mix up the notification procedures!

Overcrowding and Space Requirements

While the Roommate Law overrides your lease, it does not override fire codes and safety regulations. You cannot pack 10 people into a studio.

NYC Housing Maintenance Code (§ 27–2075) sets minimum space requirements:

Every person must have at least 80 square feet of living space.
Living space excludes bathrooms, closets, and hallways.

If adding a roommate would result in less than 80 square feet of livable space per person, the landlord can legally block the arrangement on safety grounds. This is rare for a typical 1-bedroom apartment with two people, but common in very small studios or "micro-units."

FAQ: Common Questions

Q: Does my roommate need to be on the lease? No. In fact, most landlords prefer not to add roommates to the lease. This gives you more control—if things go south, you can evict the roommate (through proper court proceedings) without the landlord's involvement. If they are on the lease, they have equal rights to the apartment.

Q: Can the landlord raise my rent for having a roommate? In a Rent Stabilized apartment? Absolutely not. The rent is legally fixed. In a Market Rate apartment? They cannot raise it during the lease term. However, when your lease expires, they can raise the rent as much as they want (unless Good Cause Eviction protections apply to your building), and they might use the extra occupant as a justification.

Q: Can my landlord deny keys to my roommate? This is a gray area, but generally, courts have frowned upon landlords creating barriers to legal occupancy. If you have a legal right to a roommate, that roommate implies a right to access the apartment. However, landlords can charge a reasonable fee for key duplication or fob issuance.

Q: What if my roommate is my boyfriend/girlfriend? Legally, they are just an "occupant." The law doesn't care about your romantic status unless you are married (which makes them immediate family). If you are unmarried, they count towards your "one additional occupant" limit.

Q: Does the law apply to public housing (NYCHA)? No. NYCHA and Section 8 have their own strict rules about household composition and income limits. The Roommate Law generally does not override federal HUD regulations.
