Life in New York doesn’t always go according to plan. You take a job in another city for six months. You move in with a partner. You need to travel for work. Whatever the reason, subletting your apartment can feel like an obvious solution — but in NYC, doing it wrong can cost you your home permanently. Here’s exactly what the law says you can and can’t do in 2026.

Your Legal Right to Sublet (and Its Limits)

New York State law gives tenants in buildings with four or more apartments the right to sublet their unit — but only with the landlord’s written consent in advance. This right is established under New York Real Property Law § 226-B. Importantly, any lease clause that categorically prohibits subletting is void under New York law. Landlords cannot simply refuse without a legitimate reason.

There are important exceptions. Tenants in buildings with three or fewer units do not have a statutory right to sublet — your landlord can decline without providing any reason at all. Tenants in public housing, HUD-subsidized housing, project-based Section 8, co-ops, or non-profit buildings generally cannot sublet, or face significant additional restrictions beyond what is described here.

The Legal Process: How to Ask Your Landlord

According to the NYC Rent Guidelines Board, the correct process is:

1. Send written notice by certified mail, return receipt requested — at least 30 days before your proposed sublet start date. A text message or email does not satisfy this legal requirement.
2. Your notice must include: a copy of the proposed sublease (with start and end dates), identification of the proposed subtenant, and a copy of your current lease if available.
3. The landlord has 10 days to request additional information about the proposed subtenant — and you must provide it as long as the request is not unduly burdensome.
4. After receiving all required information, the landlord has 30 days to approve or deny. If your landlord does not respond within 30 days, silence is legally deemed consent.

If the landlord denies your request, they must give a legitimate reason — for example, the proposed subtenant has poor credit or no verifiable income. If you believe the denial is unreasonable, you can proceed with the sublet and seek a court determination. If a court finds the landlord acted in bad faith, you may recover attorney’s fees. That said, litigation is expensive and stressful, and should be a last resort.

Special Rules for Rent-Stabilized Tenants

If your apartment is rent-stabilized, subletting is permitted but comes with additional constraints:

• You cannot charge the subtenant more than your legal regulated rent. The one exception: if you sublet a furnished apartment, you may charge up to 10% above your stabilized rent. Charging more is considered rent overcharging and can be reported to the NYS Division of Housing and Community Renewal (DHCR) at hcr.ny.gov.
• You cannot sublet for more than two years out of any four-year period. Using a stabilized apartment as a revolving rental is grounds for eviction and permanent loss of the unit.
• The apartment must remain your primary residence. You must genuinely intend to return. Temporary job assignments, medical situations, and family caregiving qualify. Treating the apartment as an investment property does not.

Short-Term Rentals: The Airbnb Problem

This is where many New Yorkers get into serious trouble. Under the NYC Multiple Dwelling Law, renting your apartment for fewer than 30 days is not a legal sublet — it’s an illegal short-term rental, and the distinction matters enormously. This applies regardless of platform: Airbnb, Vrbo, or private arrangement.

The only exception: you may rent a room in your apartment on a short-term basis if you are physically present for the entire stay. Renting your whole unit while you’re away — even for a single weekend — violates the law.

NYC actively enforces short-term rental rules through the Mayor’s Office of Special Enforcement. Violations can result in significant fines and, for rent-regulated tenants, eviction proceedings. The risk to your tenancy is not worth the income.

What Happens If You Sublet Illegally

An illegal sublet — subletting without proper notice, without landlord consent, or in violation of rent stabilization rules — gives your landlord grounds to begin eviction proceedings against both you and your subtenant. You remain liable for any damage your subtenant causes even while you’re away. And if you’re in a rent-stabilized apartment, an illegal sublet can result in losing that unit permanently — a loss that cannot be appealed away once the eviction is final.

When Subletting Makes Sense

Subletting is a legitimate tool when used correctly. It works well for temporary work assignments out of the city, medical or family situations requiring temporary relocation, a trial period before deciding to move in with a partner (while maintaining your apartment as a backup), or a sabbatical or study period abroad. In all of these cases, documentation is everything: follow the certified mail process, keep copies, and make sure your subtenant understands the written terms.

Action Steps: How to Sublet the Right Way

• Start early. You need at least 30 days for the notice process. Don’t wait until two weeks before you need to leave.
• Send your subletting request via certified mail and keep the return receipt. This is your proof that the 30-day clock started.
• Use a written sublease. NYC Bar Association guidance at nycbar.org explains what it should include.
• Check your stabilization status at apps.hcr.ny.gov/BuildingSearch/ before setting rent for your subtenant.
• Document landlord non-response. If 30 days pass with no reply, their silence is legal consent — but you’ll want a paper trail if anything is later disputed.
