A New York room rental agreement is the written contract between the person on the lease (the primary tenant) and the person moving into a spare bedroom, and under state law it needs to cover the room itself, the rent and utility split, the security deposit, house rules, and how either side can end the arrangement — all within the limits set by the Roommate Law, the rent regulations that may apply to the apartment, and the state’s deposit and notice statutes.
Get the terms on paper before any money changes hands. The primary tenant stays fully liable to the landlord for the full rent no matter what the roommate pays, so the document is doing real work from day one.
Your Right to Rent Out a Room
New York Real Property Law § 235-f, known as the Roommate Law, prohibits landlords from restricting occupancy to only the named tenant and their immediate family. Any lease clause that tries to do so is unenforceable. A tenant who lives in the apartment as a primary residence can share it with immediate family, one additional occupant, and that occupant’s dependent children.1New York State Senate. New York Real Property Law 235-F – Unlawful Restrictions on Occupancy
There is one disclosure obligation attached to that right. The primary tenant must give the landlord the occupant’s name within 30 days of the occupant moving in, or within 30 days of a written request from the landlord.1New York State Senate. New York Real Property Law 235-F – Unlawful Restrictions on Occupancy Build that acknowledgement into the agreement so neither party is caught off guard when the landlord asks.
One boundary worth naming: the Roommate Law covers the situation where you still live in the apartment. If you move out and hand the unit to someone else, that is a sublet under Real Property Law § 226-b, which requires the landlord’s advance written consent.2New York State Senate. New York Real Property Law 226-B – Right to Sublease or Assign A room rental agreement is not the right tool for that.
How Much You Can Charge a Roommate
In a rent-stabilized apartment, you cannot charge a roommate more than their proportional share of the legal regulated rent. One tenant with one roommate means neither person should pay more than half. Charging above that share violates the Rent Stabilization Code and can trigger eviction proceedings against the primary tenant, and a willful overcharge can expose you to treble damages — three times the overcharge amount.3New York State Homes and Community Renewal. Rent Increases and Rent Overcharge
In a rent-controlled apartment, the landlord may add a 10% surcharge when a roommate moves in, and the primary tenant can pass that cost along, but the total collected from both people still cannot exceed the total legal rent. In a market-rate apartment, no proportional-share rule applies, and you can negotiate whatever split works, so long as the deposit stays within legal limits.
What the Agreement Needs to Spell Out
Vague terms invite the exact disputes the document is meant to prevent. Each of the following should appear in writing.
The Room and Shared Spaces
Identify the specific bedroom: “rear north bedroom” or “second-floor bedroom adjacent to the bathroom,” not just “a room.” List which areas are shared (kitchen, bathroom, living room) and name any spaces that are off-limits. If storage areas such as closets, basement bins, or garage space are included, say so.
Rent, Utilities, and Payment
State the monthly rent, the day it is due, and the acceptable payment methods. Utilities are the single most common source of roommate friction, so set out how electricity, gas, internet, and any other recurring bills are divided — equal shares, a fixed dollar amount, or a percentage. If the roommate’s contribution covers consumables like cleaning supplies or shared groceries, pin down a monthly amount instead of leaving it to informal negotiation.
Duration and Renewal
Say whether the arrangement runs month-to-month or for a fixed term with a specific end date. A fixed term gives both sides predictability; month-to-month offers flexibility but relies on the notice rules below. If you choose a fixed term, address what happens when it expires: automatic conversion to month-to-month, or move-out.
House Rules
Guest policies, quiet hours, and cleaning responsibilities belong in writing. Reasonable terms might include a limit on overnight guests (for example, no more than five per month, or no more than one at a time without advance notice) and a noise cutoff after 10 p.m. on weekdays. Smoking, pets, and parking should also be addressed if they are relevant. These sound minor until someone’s guest has been sleeping on the couch for three weeks.
Security Deposit Rules
New York General Obligations Law § 7-108 caps the security deposit at one month’s rent. Collecting first month, last month, and a deposit violates the statute.4New York State Senate. New York General Obligations Law 7-108 – Deposits Made by Tenants of Non-Rent Stabilized Dwelling Units The cap applies to the primary tenant collecting from a roommate, not just to traditional landlord-tenant relationships.
Under General Obligations Law § 7-103, the deposit remains the property of the person who paid it. The primary tenant must hold those funds in a bank account located in New York State and cannot mix the money with personal funds. After depositing it, the primary tenant must give the occupant written notice identifying the bank’s name and address.5New York State Senate. New York General Obligations Law 7-103 – Money Deposited or Advanced for Use or Rental of Real Property
When the roommate moves out, the primary tenant has 14 days to return the deposit along with an itemized statement explaining any deductions. Missing that deadline forfeits the right to keep any portion of the deposit, even if the room genuinely sustained damage.4New York State Senate. New York General Obligations Law 7-108 – Deposits Made by Tenants of Non-Rent Stabilized Dwelling Units Walk through the room together before move-in and photograph any existing damage. That record protects the roommate from unfair deductions and protects the primary tenant from arguments about pre-existing conditions.
Required Disclosures to Attach
Several disclosures are required in New York residential rentals. The primary tenant will not have all of this information independently; much of it comes from the building owner, so gather it before finalizing the agreement.
- Sprinkler system. Real Property Law § 231-a requires every residential lease to include a conspicuous, bold-face notice about whether the unit has a maintained and operative sprinkler system, with the date of the last inspection if one exists.6New York State Senate. New York Real Property Law 231-A – Sprinkler System Notice in Residential Leases
- Lead-based paint. Federal law requires disclosure of any known lead-based paint or lead hazards in housing built before 1978. The occupant must receive the EPA pamphlet “Protect Your Family From Lead in Your Home” and a signed lead warning statement before the agreement takes effect.7US EPA. Lead-Based Paint Disclosure Rule Section 1018 of Title X
- Bedbug history (New York City). Building owners in New York City must give tenants signing a vacancy lease the property’s bedbug infestation history, including whether eradication measures were taken. Request this from the landlord and share it with the occupant.8NYC Department of Housing Preservation and Development. Bedbugs – HPD
- Window guards (New York City). Buildings with three or more apartments must provide approved window guards in any unit where a child age 10 or younger lives. Building owners must give tenants a notice form asking whether children in that age range reside in the apartment.9NYC Department of Health. Window Guards Landlord
Have the roommate sign each disclosure form to confirm receipt, and keep copies with the agreement itself.
Ending the Arrangement
A fixed-term agreement expires on its stated end date, and neither party owes notice unless the agreement says otherwise. Month-to-month arrangements require advance written notice, and the required period scales with how long the roommate has lived there. Under Real Property Law § 226-c, the minimums are:
- Less than one year of occupancy: at least 30 days’ notice
- One to two years of occupancy: at least 60 days’ notice
- More than two years of occupancy: at least 90 days’ notice10New York State Senate. New York Real Property Law 226-C – Notice of Termination
These apply in both directions. The agreement can require longer notice than the statutory minimum, but not shorter.
If the roommate refuses to leave after proper notice, the primary tenant cannot change the locks or move their belongings out. New York requires a court proceeding, specifically a holdover case in housing court, to lawfully remove someone from a dwelling.11New York State Homes and Community Renewal. Eviction Self-help evictions are illegal, and a primary tenant who attempts one can face liability. That is one of the strongest reasons to screen a prospective roommate carefully before signing anything.
If the Roommate Stops Paying
Small claims court is the standard venue for recovering unpaid rent or utility shares. In New York City, claims up to $10,000 can be filed in small claims court.12NYC 311. Small Claims Court for Disputes Up to $10,000
Before filing, send a demand letter by certified mail stating the exact amount owed, when payments were due, and a deadline to pay. Say clearly that you will sue if the deadline passes. Judges expect to see that you tried to resolve the dispute first.
At the hearing, bring the signed agreement, bank statements showing past payments and the gap where they stopped, copies of utility bills, and any text messages or emails discussing the debt. An agreement that clearly states the roommate’s monthly obligation makes the case significantly easier to prove than reconstructing an oral understanding from memory.
Signing and Delivering the Agreement
Both parties must sign for the agreement to be enforceable. Under the New York Electronic Signatures and Records Act, electronic signatures carry the same legal weight as handwritten ones, so signing remotely through a digital platform is valid.13Office of Information Technology Services. Electronic Signatures and Records Act (ESRA) Regulation
Give the roommate a complete copy once signed, at the same time as or immediately after the first month’s rent and the security deposit change hands. Get a written receipt for both payments. The signed agreement, the receipts, and the disclosure forms together create a paper trail that protects both sides from day one.
Tax Side for the Primary Tenant
Money collected from a roommate is generally taxable income and the IRS expects it reported. When you are renting out a room in a home you also live in, the income and related expenses are typically reported on Schedule E (Form 1040).14Internal Revenue Service. Topic No. 414, Rental Income and Expenses
You can deduct a proportional share of expenses against that income — mortgage interest or the rent you pay, utilities, insurance, and repairs, allocated by the square footage the roommate occupies relative to the total living space. When you also use the property as your home, though, deductible rental expenses cannot exceed rental income. You cannot generate a rental loss to offset other income in this scenario.
Security deposits are not counted as income so long as you intend to return them. If you keep part or all of a deposit because the roommate broke the agreement or damaged the room, the amount retained becomes income in the year you keep it.14Internal Revenue Service. Topic No. 414, Rental Income and Expenses The dollar figures in a single-room arrangement can look small, but unreported rental income is unreported rental income.
Fair Housing Limits on How You Choose
Federal fair housing law prohibits discriminatory advertising for housing, and the rule applies even when you are looking for someone to share your own living space. You cannot post a listing that expresses a preference or limitation based on race, color, religion, national origin, disability, or familial status. A narrow exception exists for gender preference in shared-living situations where residents share a bathroom, kitchen, or other common areas: you can advertise for a roommate of the same gender. Advertising across genders (“male seeking female”) is not covered by that exception. The shared-living context gives you some flexibility in your actual selection, but the safest approach is to keep any listing focused on the room, the rent, and the logistics rather than on the characteristics of the person you hope to find.
