New York commercial lease law gives business tenants far less statutory protection than residential renters receive. The state treats commercial parties as sophisticated negotiators, so the written lease controls almost every aspect of the relationship, and courts rarely rewrite terms after the fact. A handful of statutes do set a floor — on lease formation, security deposits, eviction procedure, and a few tenant rights — but the deal you sign is the deal you live with. Knowing where the law protects you and where it doesn’t is the difference between a workable lease and an expensive mistake.
The Lease Has To Be in Writing
Under New York’s Statute of Frauds, any lease for longer than one year must be in writing and signed by the party you want to enforce it against. General Obligations Law § 5-703 makes an oral multi-year lease void, not merely hard to prove.1New York State Senate. New York General Obligations Law 5-703 – Conveyances and Contracts Concerning Real Property Required to Be in Writing If you occupy space under an oral deal that was supposed to run several years, a court will treat you as a month-to-month tenant at best, which means either side can end things on short notice.
Courts also look for the elements that confirm a real agreement exists: the names of both parties, a description of the space precise enough to identify it, the rent amount, the payment schedule, and the lease term. Missing any of these invites a challenge that no binding agreement was reached. In multi-unit buildings, the premises description deserves particular care. A reference to “the second-floor office” may not survive if there is more than one.
Recording a Memorandum of Lease
For leases longer than three years, you can record a memorandum of lease with the county clerk instead of filing the full agreement, which puts the public on notice of your tenancy without disclosing every financial term. The memorandum must include the names and addresses of both parties, the execution date, a description of the premises, the start and end dates, and any renewal or extension rights.2New York State Senate. New York Real Property Law 291-C – Recording Memoranda of Leases
Recording matters because an unrecorded lease can be wiped out by a later buyer who purchases the property without knowledge of your tenancy. If your landlord sells and the new owner had no notice, you can lose your space. Any unrecorded modification to a recorded lease is likewise void against a later good-faith purchaser.3New York State Senate. New York Real Property Law 291-CC – Recording Modifications of Leases For any long-term commercial lease, filing a memorandum is cheap insurance.
What The Law Won’t Fill In For You
The biggest surprises for commercial tenants come from protections that exist for residential renters but not for them. On these points, if the lease doesn’t give you the right, you don’t have it.
No implied warranty of habitability. Commercial tenants take the space largely as they find it. Unless the lease specifically obligates the landlord to make repairs, that obligation falls on you. New York courts enforce cost-allocation language strictly — if your lease says you pay “all maintenance,” you pay even when the HVAC system fails six months into your term.
No implied warranty of fitness. Courts do not imply that the space is fit for any particular business purpose. If you sign intending to open a restaurant but the plumbing cannot support a commercial kitchen, that is your problem. The same goes for zoning: unless the lease includes a specific representation about permitted uses, the landlord is not responsible if your intended use violates local law. A physical inspection, zoning check, and review of the certificate of occupancy are not optional before you sign.
No statutory right to assign or sublet. Real Property Law § 226-b, which gives residential tenants a right to sublet or assign, does not apply to commercial tenancies.4New York State Senate. New York Real Property Law 226-B – Right to Sublease or Assign If your lease is silent or flatly prohibits assignment, you are stuck. At minimum, push for language requiring that the landlord not unreasonably withhold consent. Without it, the landlord can refuse for any reason or no reason at all. This matters most for tenants who may want to sell the business later, because the sale often depends on transferring the lease.
Quiet enjoyment is implied. One protection does come built in: every commercial lease carries an implied covenant that the landlord will not interfere with your use and occupancy. If the landlord’s conduct — cutting off utilities, blocking access, allowing persistent flooding from above — makes the premises effectively unusable, you may have grounds for constructive eviction, which lets you terminate the lease and stop paying rent. The standard is high, and most courts expect you to actually vacate before claiming it.
Security Deposit Rules
General Obligations Law § 7-103 does impose real constraints on commercial security deposits. The deposit remains your money, held in trust, and the statute prohibits mixing it with the landlord’s personal or business funds.5New York State Senate. New York General Obligations Law 7-103 – Money Deposited or Advanced for Use or Rental of Real Property
If the landlord deposits the funds in a bank, the bank must have a New York State location, and the landlord must promptly notify you in writing of the bank’s name, address, and the deposit amount. When the account bears interest, the landlord may keep one percent per year as an administrative fee; the rest belongs to you, either held in trust or paid annually.
Any lease clause purporting to waive these protections is void. A landlord who ignores the trust and notification rules weakens any later claim to keep the deposit for damages or unpaid rent, though the statute does not spell out one automatic penalty. In a dispute, noncompliance becomes a strong tenant argument.
Personal Guarantees and the Good Guy Guarantee
Most New York commercial landlords require a personal guarantee, especially from tenants operating through an LLC or corporation. Under General Obligations Law § 5-701, a promise to answer for another’s debt must be in writing and signed by the guarantor.6New York State Senate. New York General Obligations Law 5-701 – Agreements Required to Be in Writing An oral guarantee is worthless.
The “good guy guarantee” is a distinctly New York arrangement common in Manhattan and other high-demand markets. Rather than guaranteeing all rent for the full term, the guarantor’s liability ends once the tenant vacates and surrenders the space. If the business fails, the guarantor walks away as long as the tenant leaves voluntarily and pays rent through the departure date.
A 2025 Court of Appeals decision clarified when that release takes effect. The court held that a guarantor’s liability terminates when the tenant vacates, gives notice, and hands over the keys, even if the landlord never formally accepts the surrender in writing. Requiring written acceptance, the court reasoned, would make the vacating and notice provisions meaningless. For tenants and guarantors, the takeaway is that leaving the space and giving written notice are what trigger release.
Yellowstone Injunctions: What To Do When a Default Notice Arrives
One of the most important tools for a New York commercial tenant is the Yellowstone injunction, named for a 1968 Court of Appeals decision. When your landlord sends a notice of default or notice to cure, the clock starts running toward termination. A Yellowstone injunction freezes that clock by asking the court to stop the landlord from terminating while the alleged default is disputed or cured.
A commercial tenant generally must show four things to get one: a commercial lease, a notice of default or similar notice, a filing made before the cure period expired, and the willingness and ability to cure if a default exists. Unlike a typical preliminary injunction, you do not need to prove likelihood of success on the merits or irreparable harm. Timing is everything. Miss the cure period, and the remedy is gone.
Real Property Law § 235-h now prohibits lease provisions that waive a commercial tenant’s right to bring a declaratory judgment action regarding lease terms. That is the procedural vehicle that supports Yellowstone relief, and the statute was designed to stop landlords from drafting that protection out of their leases.
How a Commercial Eviction Works
A New York landlord cannot change the locks. Removing a commercial tenant requires a summary proceeding under RPAPL Article 7, which is faster than a full civil suit but carries strict procedural requirements.7New York State Senate. New York Real Property Actions and Proceedings Law Article 7 – Summary Proceeding to Recover Possession of Real Property
Grounds
RPAPL § 711 lists the grounds. The two most common for commercial tenants are holdover — staying after the lease ends without permission — and nonpayment, which requires the landlord to serve a written demand giving at least fourteen days to pay or surrender.8New York State Senate. New York Real Property Actions and Proceedings Law 711 – Grounds for Summary Proceeding Other grounds include failing to pay property taxes or assessments for sixty days when the lease requires it, and illegal use of the premises. The fourteen-day rent demand is a prerequisite, not a formality. Landlords who skip it or serve it improperly can have the proceeding dismissed.
Process and Timing
The landlord files a Notice of Petition and Petition in the appropriate court. For holdover cases, the notice of petition must be served at least ten and no more than seventeen days before the hearing.9New York State Senate. New York Real Property Actions and Proceedings Law 733 – Time of Service Nonpayment proceedings follow a separate timeline under RPAPL § 732. The petition must lay out the factual basis, whether that is unpaid rent, specific lease violations, or another ground.
If the landlord wins, the court issues a judgment of possession and a warrant of eviction. The warrant cannot be executed immediately: the officer must give the tenant at least fourteen days’ written notice before physically removing them.10New York State Senate. New York Real Property Actions and Proceedings Law 749 – Warrant That window is your last opportunity to remove equipment, inventory, and fixtures.
No Discretionary Stay
Residential tenants can request a discretionary stay of eviction for up to one year under RPAPL § 753. Commercial tenants cannot. Section 753 applies only to premises “occupied for dwelling purposes,” so once you lose a summary proceeding, there is no statutory mechanism to delay the warrant beyond the fourteen-day notice. That makes pursuing a Yellowstone injunction before the cure window closes far more valuable than waiting until the landlord has already filed.
Holding Over After the Lease Ends
When a commercial lease expires and the tenant stays without a new agreement, the tenancy generally converts to a month-to-month arrangement. Outside New York City, either party can terminate a commercial month-to-month tenancy with at least one month’s notice before the end of a monthly period.11New York State Senate. New York Real Property Law 232-B – Notification to Terminate Monthly Tenancy or Tenancy From Month to Month Outside the City of New York Within New York City, local rules and case law govern notice.
Holding over is risky. The landlord can treat you as a trespasser and start eviction, or hold you to a new term at a higher rent. Many leases include holdover penalty clauses that increase rent to 150% or 200% of the prior rate, and courts generally enforce them when the language is clear. The safer path is to negotiate renewal six to twelve months before expiration rather than drifting into holdover status.
NYC Commercial Rent Tax and Transfer Tax
If your space is in Manhattan south of 96th Street, factor in the New York City Commercial Rent Tax. It applies once annual rent reaches $250,000. The nominal rate is 6% of base rent, but a 35% rent reduction applied to all taxpayers brings the effective rate to 3.9%.12New York City Department of Finance. Commercial Rent Tax (CRT) Tenants with annual rents between $250,000 and $300,000 get a sliding-scale credit, and a small business credit effectively exempts tenants with total income of $5 million or less and annual base rent under $500,000. The obligation sits with the tenant, not the landlord, and penalties for not filing add up quickly.
Transfer tax can also hit commercial leases. Creating a new lease is taxable when the initial term plus renewal options exceeds 49 years, substantial capital improvements are or may be made for the tenant’s benefit, and the lease covers substantially all of the premises. Transferring an existing leasehold — assigning the lease to a buyer of your business, for example — is taxable regardless of remaining term, with the consideration being whatever the buyer pays for the assignment. The state rate is 0.40% of consideration, and commercial property in New York City valued at $2 million or more carries an additional 0.65% city rate. One useful distinction: if a landlord pays you to surrender a lease, the payment is taxable consideration, but if you pay the landlord to terminate early, no transfer tax applies because the lease is ending rather than being conveyed.
