Quick Summary - What You Need to Know

  • Real Property Law 226-b gives your landlord 30 days to consent or state reasons after your certified-mail sublet request.
  • No answer inside 30 days is deemed consent, so a silent landlord has legally approved the sublet.
  • The right covers only buildings with four or more residential units, and consent can't be unreasonably withheld.
  • Rent-stabilized NYC tenants may sublet at most two years in any four-year period and must keep the unit as a primary residence.
  • Charging a subtenant above the stabilized rent risks damages, and profiteering cases can reach treble damages.

Understanding the Subletting Clause

30 days
Landlord's deadline to answer a written sublet request in
In a building with four or more units, your landlord has 30 days to answer a certified-mail sublet request - silence counts as yes.

A subletting clause decides whether you can hand your apartment to someone else for a stretch - a job transfer, a semester away, a trial move-in with a partner. Most New York City leases write it as though the landlord's answer is final and unreviewable.

It isn't. In a dwelling with four or more units, Real Property Law 226-b gives you a statutory right to request a sublet, and the landlord gets 30 days to consent or put the reasons for refusal in writing.

What renters assume

Renters read "no subletting without landlord consent" and assume the landlord can ignore the request or refuse it for any reason at all.

What is actually true

In buildings with four or more units, consent can't be unreasonably withheld, and no written answer within 30 days is deemed consent.

New York is the only city on this chart with a real clock. Texas bars subletting without prior consent and sets no deadline at all, and Chicago makes landlords accept a reasonable sublease but never says by when - here, 30 days of silence is a yes.

Plain English Version

It's like mailing a wedding RSVP with tracking: the host has 30 days to say yes or give a real reason for no. Blow past the deadline with no reply, and you get marked down as a yes.

Sublet Clause Example - What the Wording Looks Like in New York City, NY

The sample clause below is real lease language - a court quoted it word for word, and then ruled on it. What the judge decided is at the bottom of this block.

Real clause - quoted in a published court opinion

Find the equivalent paragraph in your own lease and read the two side by side. The wording will differ; the moving parts rarely do.

18. (A) Assignment, subletting.—Except as provided by § 226-b of the Real Property Law of New York, the Tenant shall not assign the lease, nor sublet the Apartment, or permit the Apartment or any part thereof to be used by any one other than Tenant or members of the immediate family of Tenant, without the prior written consent of Owner in each case, if the Lease is assigned, or if the Apartment is sublet or occupied by anybody other than Tenant or Tenant’s immediate family.

Quoted from the published opinion in Conrad v. Third Sutton Realty Co., 81 A.D.2d 50 (1st Dep't 1981). Judicial opinions are not subject to copyright; the lease language is reproduced in limited part for commentary under 17 U.S.C. § 107.

1

“Except as provided by § 226-b”

Your lease opens by surrendering. That carve-out is the landlord's own acknowledgement that the paragraph underneath it is not the last word - the statute is. The right belongs to a tenant in a dwelling with four or more residential units, and it survives whatever the rest of paragraph 18 goes on to say. Conrad is what happens when a landlord forgets that: the clause was intact and fully enforceable on its face, and the tenant still got a court declaration that she could sublet - and with it the right to compel acceptance of the bona fide subtenant she had proposed.

The right is conditional on how you ask. The request goes by certified mail, return receipt requested, and must carry the term of the sublease, the subtenant's name and address, your reason for subletting, and your own address during the sublet. A request missing one of those may not be the request the statute protects, which is why the checklist, and not the phone call, is what starts the clock.
Tenant-favourable“Tenant may sublet as permitted by law, and Owner shall answer any request in writing within 30 days”
What this lease said“Except as provided by § 226-b”
Landlord-favourable“Tenant waives any statutory right to sublet; subletting is prohibited in all circumstances”
2

“nor sublet the Apartment”

Four words that a clock can overrule. The landlord gets 10 days to demand reasonable additional information about the person you propose, and then 30 days from your request - or from that extra information, whichever falls later - to consent or to state reasons for refusing. Failing to send that notice within 30 days is deemed consent. Conrad reached the same destination by the other road: the landlord there did answer, but gave no reason for the refusal, and a refusal with no reasons was treated as a yes.

Count from the right date. If the landlord demands additional information inside the 10-day window, the 30 days runs from the day you supply it, so a slow answer of your own moves the deadline you are relying on. Diary both dates when you post the certified letter, and send the extra information the same way.
Tenant-favourable“Owner shall not unreasonably withhold consent to a sublease and shall respond in writing within 30 days”
What this lease said“nor sublet the Apartment”
Landlord-favourable“No sublease is effective unless Owner countersigns; Owner's failure to reply is a refusal”
3

“without the prior written consent of Owner”

Written consent is still what you want in hand - but in New York it is not the only way to get it. A refusal that gives no reasons is not a refusal that counts, and a refusal that gives bad ones is a refusal you can test, because consent cannot be unreasonably withheld. That is the whole distance between this state and Massachusetts, where the Supreme Judicial Court read almost identical words and held they let a landlord say no for no reason at all.

There is money attached to a bad refusal. Where a court finds the denial was in bad faith, a tenant can recover costs and attorney's fees. Keep the certified-mail receipt, the returned green card and the landlord's reply, because the case turns entirely on what was sent, what came back, and when.
Tenant-favourable“Owner shall state in writing the specific reasons for any refusal within 30 days of the request”
What this lease said“without the prior written consent of Owner”
Landlord-favourable“Owner may withhold consent in Owner's sole and absolute discretion, without stating reasons”

“or if the Apartment is sublet or occupied by anybody”

This is where the city's own limits land. A rent-stabilized tenant may sublet for no more than two years in any four-year period and must keep the apartment as a primary residence - the sublet is a gap in your occupancy, not a handover. For a furnished sublet the surcharge is capped at 10%, and a subtenant charged beyond the stabilized rent can sue for damages, including treble damages in profiteering cases.

Both limits are cumulative, which is what catches people out. The two years runs across any four-year period, so two short sublets a year apart add up, and primary residence has to stay true throughout - it is a condition of the whole arrangement, not a box ticked at the start.
Tenant-favourable“Tenant may sublet up to the maximum period allowed by law; no surcharge beyond the lawful amount”
What this lease said“or if the Apartment is sublet or occupied by anybody”
Landlord-favourable“Occupancy by any person not named herein is a substantial breach and terminates the tenancy”
What the court did with it

A landlord who gives no reason is treated as having said yes. The tenant proposed a documented sublessee; the managing agent's reply gave no reason at all - only that permission would not be granted, with an offer to let her terminate the lease instead. The Appellate Division held that a landlord who rejects a residential sublease without stating any valid reason is deemed to have consented under Real Property Law § 226-b, and that the tenant may compel acceptance of a bona fide sublessee. The court rejected the argument that release from the lease was the tenant's only remedy: in a housing shortage, that reading would leave a tenant with a meaningless right to surrender. Read the panel accurately - a divided panel affirmed, three judges adopting the rationale below, while two concurred separately on a narrower reading of § 226-b (2) and expressly declined to say what happens when a landlord does state reasons that turn out to be unreasonable. One of them noted that this lease carried no provision that consent would not unreasonably be withheld, which is why the statute had to do all the work. Read it with its date, too: this construes § 226-b before its substantial 1983 amendment. The deemed-consent result still tracks current § 226-b (2) (c), but today's statute also expressly lets a tenant sublet where consent is unreasonably withheld - the very question the concurrence reserved. The unit was a Manhattan apartment; the words rent control and stabilization appear nowhere in the opinion. Printed above is the first sentence of paragraph 18(A); the paragraph runs on for another 107 words of non-waiver boilerplate that is not reproduced here.

New York is the one place on this site where the calendar can decide your sublet. In a building with four or more residential units, a landlord who does not answer a properly mailed request within 30 days is treated as having consented, and consent cannot be unreasonably withheld: N.Y. Real Prop. Law § 226-b

One court, one lease, one state. That answer is not automatically yours, and your lease may be worded to land differently. Use this to know what to look for and what to ask - your state's tenant hotline or a local tenant attorney can answer it for your document.

New York Law on Subletting Clause

The law in New York
  • The right applies only to a tenant in a dwelling with four or more residential units.
  • The tenant must mail the sublet request by certified mail, return receipt requested, with the sublease term, the subtenant's name and address, the reason, and the tenant's address during the sublet.
  • The landlord has 10 days to demand reasonable additional information, then 30 days from the request or from that information (whichever is later) to consent or state reasons for refusal.
  • Failure to send the notice within 30 days is deemed consent, and a tenant can recover costs and attorney's fees where a court finds the denial was in bad faith.

N.Y. Real Prop. Law § 226-b - statutes change; verify the current text for your situation.

The procedure is the whole ballgame in New York. Send the request by certified mail, return receipt requested, and include the sublease term, the subtenant's name and address, your reason, and where you'll be living during the sublet - a request missing those pieces doesn't reliably start the 30-day clock.

Your landlord then gets 10 days to demand reasonable additional information, and the 30 days runs from the request or from that information, whichever is later. Compare Texas, where Property Code 91.005 bans subletting without prior consent with no deadline and no reasonableness test, or Los Angeles, where the Civil Code's reasonable-consent rule covers non-residential leases only.

New York Tenant Protections

In a dwelling with four or more residential units, Real Property Law 226-b gives you the right to request a sublet and bars your landlord from unreasonably withholding consent. If no written notice of consent or refusal is sent within 30 days, the law deems the sublet consented to. Where a court finds the denial was made in bad faith, you can recover your costs and attorney's fees.

New York City stacks hard limits on top of the state right, and most of them land on rent-stabilized apartments. A stabilized tenant can sublet no more than two years in any four-year period, has to keep the unit as a primary residence, and may add only a 10% surcharge when the sublet is furnished.

That 10% cap is where NYC sublets go wrong. Market rents sit far above stabilized rents, so tenants get tempted to charge the spread - and a subtenant billed above the stabilized rent can sue for damages, reaching treble damages in profiteering cases.

Does the lease allow a written sublet request?

It should. In a building with four or more units, RPL 226-b gives you that right regardless of what the paragraph says.

Does it say where to mail the request?

Useful, and the method matters more. Certified mail, return receipt requested, is your proof of the date the 30-day clock started.

Does it ban subletting outright with no process?

Red flag in a four-unit-or-larger building. Your right to request and to get an answer in 30 days comes from statute, not the lease.

Does it charge a fee for sublet approval?

Ask what it covers and get it in writing. If your unit is rent-stabilized, the only surcharge allowed is the 10% for a furnished sublet.

Red Flags to Watch Out For

  • Blanket ban on all subletting

    In a dwelling with four or more units, RPL 226-b gives you a right to request and be answered, whatever that lease paragraph claims.

  • Consent at landlord's sole discretion

    The statute says consent can't be unreasonably withheld. Sole-discretion wording tries to write that standard out of your rental agreement.

  • Sublet fee or processing charge

    Get the amount and its purpose in writing. For a rent-stabilized unit, the only increase permitted is the 10% surcharge on a furnished sublet.

  • Verbal-only request process

    A clause pointing you to a phone call or a text costs you proof. Certified mail, return receipt requested, is what dates the 30-day deadline.

  • Automatic termination if you sublet

    Wording that ends your tenancy the moment a subtenant moves in. In a four-or-more-unit building you have a statutory request process first.

Your Rights as a New York City Tenant

  • A written answer in 30 days

    Your landlord must consent or state reasons for refusal within 30 days of the request, or of any additional information demanded, whichever is later.

  • Silence counts as consent

    No notice sent inside 30 days is deemed consent under RPL 226-b. Keep the certified-mail receipt - it's what proves the date.

  • No unreasonable refusal

    In a dwelling with four or more residential units, a refusal has to rest on stated reasons, not on a flat no.

  • Fees back for bad-faith denial

    Where a court finds the denial was made in bad faith, you can recover your costs and attorney's fees on top of the ruling.

What To Do - Step by Step

1

Count the units in your building

RPL 226-b applies to dwellings with four or more residential units. Below that, your lease terms control the whole question.

2

Check if you're rent-stabilized

Order your rent history from HCR. Stabilized tenants get the sublet right plus the two-years-in-four and primary-residence limits.

3

Write the request in full

Include the sublease term, the subtenant's name and address, your reason, and your address during the sublet. Missing pieces stall the clock.

4

Send it certified, return receipt

Return receipt requested is what the statute asks for and what dates the 30-day deadline. Keep the green card.

5

Answer the 10-day information demand

Your landlord has 10 days to request reasonable additional information. Send it fast - the 30 days then runs from that date.

6

Calendar day 30 and act

No written consent or refusal by day 30? The sublet is deemed consented to. Hold every mailing receipt in case it's disputed.
