How to Legally Sublet Your NYC Apartment (Step-by-Step Guide)

TL;DR – Subletting in NYC is a legal right for most tenants in buildings with 4+ units, but you must follow a strict 30-day notice process, obtain written landlord approval, and cannot charge more than the legal rent (plus a 10% surcharge if fully furnished).

The "Golden Rule" of NYC Subletting

Many New Yorkers assume they can just hand their keys to a friend and Venmo the rent. This is the fastest way to get evicted.

In NYC, your right to sublet is protected by Real Property Law § 226-b, but this right is conditional. You must follow a specific notification procedure. If you skip a step, your landlord can legally deny your request or begin eviction proceedings.

This guide covers exactly how to navigate the process, protect your security deposit, and avoid the "illegal sublet" trap.

Part 1: Are You Allowed to Sublet?

Before listing your apartment, confirm your legal standing. Rules vary by building type.

✅ The "Yes" List

Rent Stabilized Tenants: Statutory right to sublet for 2 out of every 4 years.
Market Rate Tenants (4+ Units): Statutory right, subject to landlord approval (cannot be unreasonably withheld).
Co-op Shareholders: Subject to proprietary lease and board approval (often strict).

❌ The "No" List

Rent Controlled Tenants: No statutory right.
Public Housing (NYCHA): Strictly prohibited; grounds for termination.
Section 8: Generally prohibited.
Non-Profit / Supportive Housing: Usually prohibited.

🚩 The "Airbnb" Danger Zone

NYC's Local Law 18 bans short-term rentals (under 30 days) unless:

You are present during the stay.
You have no more than 2 paying guests.
You are registered with the Office of Special Enforcement (OSE).

Warning: Renting out your entire apartment for less than 30 days is illegal. Fines start at $1,000.

Part 2: The 10% Surcharge Rule

Can I make a profit? No. Charging more than your legal rent is "profiteering" and grounds for eviction.

The Exception

If you sublet a fully furnished apartment, you can charge a 10% surcharge.

Rent Calculation Example

Item	Monthly Cost	Notes
Base Rent	$3,000	Your lease amount
Furnished Surcharge	+$300	Max 10% allowed
Max Sublet Rent	$3,300	Legal Limit

Note: You can pass through utility costs (electricity, internet) exact-to-cost, but cannot mark them up.

Part 3: How to Get Landlord Approval

You must send a formal request via Certified Mail, Return Receipt Requested.

Step 1: Required Information (RPL § 226-b)

Term: Start and end dates.
Subtenant: Name, business address, permanent home address.
Reason: (e.g., "Temporary job relocation").
Your Contact: Address for the term of the sublease.
Consent: Written consent from co-tenants/guarantors.
Sublease Agreement: A copy of the proposed contract.

Step 2: Request Letter Template

Subject: Request to Sublet Apartment [Unit Number]

Dear [Landlord Name],

Pursuant to Real Property Law § 226-b, I request permission to sublet my apartment at [Address] from [Start Date] to [End Date].

Reason: I will be [reason] and intend to return as my primary residence.

Proposed Subtenant: Name: [Subtenant Name] Permanent Address: [Address] Business Address: [Address or "N/A"]

My Contact Info: [Your Temporary Address, Phone, Email]

Enclosed is the proposed sublease agreement and [additional docs].

Please respond within 30 days. If you require additional info, please request it within 10 days.

Sincerely, [Your Name]

Step 3: Timeline

Day 0: Landlord receives request.
Day 1-10: Can ask for "additional info" (e.g., proof of income).
Day 11-30: Must approve or deny.
No Response? If no response in 30 days, it is deemed consent.

Note: Landlords cannot "unreasonably withhold" consent. Valid denials include subtenant's bad credit or commercial use.

Part 4: Screening Your Subtenant

You are liable to the building owner for your subtenant's actions.

Screening Checklist

Credit Check: Use tenant screening apps (fees capped at $20).
Income Verification: Ask for a pay stub or employment letter (standard is 40x rent).
References: Call their previous landlord.
Social Media: Check for red flags.

🚩 Red Flags

Refusal to provide info.
Urgency: "Need to move in tomorrow."
Cash offers: "6 months up front" often hides bad history.

Part 5: The Sublease Agreement

Never sublet on a handshake. Your contract must mirror your main lease.

Essential Clauses

Term: Exact dates.
Rent: Amount and due date.
Security Deposit: Max one month's rent. Return within 14 days of end.
"Subject to Master Lease": Subtenant agrees to main lease rules (attach copy).
Damages: Subtenant is responsible for damage beyond wear and tear.
Overstaying: Penalty for not vacating (e.g., double daily rent).

Important: You pay the landlord; the subtenant pays you.

Part 6: Managing the Sublet

Rent Collection

Set up automated reminders for your subtenant five days before the rent is due. Remember, your lease obligations do not pause just because you are away. You owe the landlord the full rent on the 1st of the month, regardless of when (or if) your subtenant pays you. It is often wise to keep a buffer of one month's rent in your own account to cover any delays.

Inspections and Maintenance

It is reasonable to include a clause in your sublease allowing you (or a designated agent) to inspect the apartment with 24-48 hours notice. We recommend scheduling one inspection midway through any sublet longer than three months. This allows you to catch issues like unauthorized pets, smoking, or damage early. Additionally, clarify who handles minor repairs (like a clogged drain) versus major ones (like a leak). Typically, the subtenant should report major issues to you immediately so you can coordinate with the building management.

Eviction Risks

If they refuse to leave:

Do not change locks (Illegal lockout).
Serve Notice to Quit.
Start Holdover Proceeding in Housing Court. Screening is your best defense.

Part 7: Ending the Sublet

The Walk-Through

Inspect the apartment with the subtenant before they leave. Photos are crucial.

Returning the Deposit

Under the Housing Stability and Tenant Protection Act (2019):

Offer an inspection.
Return deposit within 14 days.
Provide itemized list of deductions. Failure to do so forfeits your right to keep any deposit.

FAQ

Can my landlord charge a sublet fee? Only for "reasonable" administrative expenses (like credit checks). No "sublet fees" for profit.

What about roommates? Subletting your entire apartment requires landlord consent. Replacing a roommate (while you stay) is a "roommate replacement" with looser rules.

Can I sublet for 2 weeks? Generally, no. Short-term rentals (under 30 days) violate the Multiple Dwelling Law unless you are present.

Does subletting reset my rent stabilization? No. You remain the prime tenant. The lease remains in your name. When you return, your rent continues as if you never left.

What if my subtenant wants to stay longer? If your subtenant wants to extend the sublease, you must go through the formal request process with your landlord again for the new dates. You cannot simply "extend" the agreement informally without risking an illegal sublet claim. Remember, rent-stabilized tenants are generally limited to subletting for two out of every four years.
