In New York City, the rights and obligations of the parties to a commercial lease are governed almost entirely by the written agreement. Unlike residential tenancies, commercial leases are not subject to most of the statutory protections. This contractual freedom creates significant opportunities for landlords to protect income streams, control use, and enforce remedies, but it also creates corresponding risks if the lease language is ambiguous, incomplete, or poorly tailored to the specific property and tenant.
Ambiguity can punish either side, but more commonly the tenant. A landlord who fails to address a particular risk may lose the ability to enforce a restriction or collect additional rent. A tenant who accepts vague language may face unexpected costs, operational constraints, or personal liability. The goal of careful drafting is therefore mutual clarity: the lease should reflect the parties’ actual intent and allocate risks in a predictable way.
This guide expands on the principal differences between commercial and residential leases in NYC, highlights lesser-known drafting issues that frequently lead to disputes, and provides sample contract language drawn from typical commercial forms.
Commercial leases generally operate under a different legal regime:
1. The landlord is not required by statute to make repairs or provide heat, hot water, or other essential services unless the lease expressly imposes those duties.
2. There is no statutory ceiling on how much rent may be increased upon renewal or after the lease ends, and the landlord has no legal obligation to renew the lease. For most tenants, these may warrant a renewal option set at pre-defined rental rates.
3. Good Cause Eviction protections do not apply; the landlord is not limited to the statutory grounds or notice periods that govern many residential tenancies.
4. The residential late-fee limitation (the lesser of $50 or 5% of the monthly rent) does not apply. Commercial late fees are governed solely by the lease and general contract principles of reasonableness.
5. Holdover rent premiums (commonly 150%–200% of the last month’s rent and additional rent) are routinely enforced.
6. Limited forms of peaceable self-help are available, although courts examine them closely, and landlords must still draft clear notice provisions.
These differences make the lease itself the primary source of rights and remedies. An ambiguity that appears minor can produce expensive consequences.
Before the lease is circulated, confirm the exact legal names and current status of all parties through the New York Department of State website (assuming New York entities). An inactive, dissolved, or misnamed entity can complicate service of process, enforcement of judgments, and the validity of the guaranty. Landlords should also verify that the individual signing on behalf of the tenant entity has actual authority.
The nature of the tenant’s business should drive several key economic and contingency terms. A restaurant that requires a liquor license, a hotel operator that must obtain a DCWP license, or a business subject to a collective-bargaining agreement may need a contingency that the lease becomes effective only upon issuance of the required license, together with a corresponding rent-abatement period and a delayed commencement date.
Certain businesses face unique risks. For a laundromat, uninterrupted supply of hot and cold water is mission-critical and should be elevated in the maintenance, utility, and interruption clauses. Taking the time to understand the tenant’s regulatory and operational framework before drafting prevents later surprises for both sides.
Most commercial leases prohibit the use or storage of “hazardous or inflammable materials” in the demised premises. That language may not clearly cover a delivery company that charges dozens of e-bikes inside the space or stores lithium-ion batteries. The same e-bikes can create a nuisance by blocking sidewalks, generate neighbor complaints and DOB or FDNY fines, or affect the insurance of the whole building. Explicitly restricting battery charging stations, indoor storage of e-bikes or scooters, and outdoor storage of such equipment closes the gap before it becomes a problem for the landlord and the other tenants.
Some types of businesses may have additional building code requirements. For example, day care centers must follow specific rules about the number and height of toilets and sinks. The NYC Department of Buildings, your architect, engineer, or code consultant can help determine these requirements.
The New York City Department of Buildings issues Certificates of Occupancy (or Temporary Certificates of Occupancy) that state the building’s legal use and permitted occupancy. No one may lawfully occupy a space until a CO or TCO has been issued. Landlords and tenants must confirm that the existing CO is consistent with the intended use described in the lease. Occupancy inconsistent with the CO is illegal and can result in violations, fines, and potential orders to vacate that affect both parties.
Determining the base year (or tax year) and carefully evaluating building occupancy are critical when negotiating or administering a commercial lease, as these factors directly affect how real estate tax escalations and operating expense pass-throughs are calculated. Misalignment between municipal tax periods and the lease's defined base year, or unusually low occupancy during the base year, can result in landlords absorbing significant unrecoverable expenses or establishing inaccurate cost-sharing baselines for tenants.
The permitted-use clause is one of the landlord’s most important control mechanisms. Broad language such as “retail use” or “office use” invites disputes and makes enforcement slower. Prefer precise descriptions:
“Tenant shall use and occupy the Demised Premises solely for the retail sale of women’s clothing and related accessories, and for no other purpose whatsoever.”
In a mixed-use building that already contains a café, a boutique, and a wellness studio, the landlord may also want to prohibit additional food-service uses, smoke shops, massage parlors, or other high-impact or controversial uses that could generate tenant complaints or DOB enforcement issues. Specificity gives the landlord clearer grounds for a default notice and faster judicial relief if the tenant strays from the agreed use.
Most commercial tenants are single-purpose limited liability companies with few assets. Landlords, therefore, routinely require a personal guaranty from the principal owner. A full personal guaranty makes the individual liable for all tenant obligations for the entire lease term. Tenants frequently negotiate a “Good Guy Guaranty” (also called a limited personal guaranty) that restricts the guarantor’s liability to the period before the tenant voluntarily vacates the premises in accordance with the lease terms. For a detailed explanation of how Good Guy Guaranties work, the notice and surrender conditions that trigger release, and the case law that governs them, see the companion article Understanding the Good Guy Guaranty in NYC Commercial Leases.
Security deposits are commonly equal to two or more months’ rent, depending on the creditworthiness of the tenant, the length of the term, and the condition of the market. Landlords may also accept (or require) an irrevocable letter of credit from an acceptable bank in lieu of or in addition to cash.
Typical landlord-protective language for a letter of credit includes:
The bank will charge the tenant a fee and may require collateral. From the landlord’s perspective, the letter of credit provides liquidity without the administrative burden of holding and accounting for a cash deposit under the General Obligations Law.
Base rent is usually calculated as an annual amount. Base rent is typically calculated by multiplying the rentable square footage of the premises by the agreed rental rate per square foot. This is what “rent per square foot” means. The rent per square foot is generally determined by the market. The landlord will charge what other landlords are charging for similar space in similar areas. The size of the space is usually the square footage of the space plus a portion of common areas, such as common hallways or bathrooms. The addition of this common space turns the “usable” area of the space into the “rentable” area. The rentable area is then multiplied by the dollar amount per square foot to determine the base rent.
Ideally, the lease should specify the makeup of the demised premises. For example, the lease may provide: the Demised Premises consists of (1) with respect to the 1st Floor, X rentable square feet, (2) with respect to the 2nd Floor, Y rentable square feet.
A clear escalation clause is essential in New York City, where operating costs, property taxes, and labor expenses tend to rise steadily. Common structures include:
Vague language such as “as necessary” or “subject to change” invites disputes. A well-drafted clause produces predictable revenue for the landlord and reduces mid-term renegotiation pressure.
In Manhattan, it is commonplace for landlords to charge additional rent that covers:
Common Area Maintenance (“CAM”)
Operating expenses;
Utilities;
Real estate taxes;
Business Improvement District charges;
Environmental compliance costs, which might arise under Local Laws, such as New York City's Local Law 97.
Landlords or their brokers should be prepared to provide estimates based on prior tenancies. Tenants can independently verify real-estate-tax figures on the New York City Department of Finance website.
Often tenants request the right to audit the landlord's books and records to verify the accuracy of additional rent calculations.
There are several options to address the payment of expenses.
Payment of Expense Increases After the Base Year: The base year establishes the starting point for the tenant’s share of property expenses. In the base year, the landlord absorbs the full cost of real estate taxes, insurance, and common-area maintenance (CAM), and those costs are built into the first year’s fixed rent. Thereafter, the tenant pays only its proportionate share of any increases in those expenses above the base-year amounts for the remainder of the lease term.
Most landlords require tenants to pay, as additional rent, their proportionate share (the ratio of the rentable square footage of the premises to the total rentable square footage of the building) of increases in real estate taxes and operating expenses above an agreed base year. The tenant’s rentable square feet divided by the building's total rentable square feet is also known as Tenant’s Share.
Sample calculation: if operating expenses are $200,000 in the base year and $250,000 in a later year, a tenant occupying 10% of the building pays $5,000 (10% of the $50,000 increase).
Cap: Another option is to put a cap on expenses so the tenant pays increases in expenses up to a certain amount. Tenants might ask to examine the books and records to confirm the accuracy of the calculation provided such information remains confidential.
The parties can elect that the annual increase in expenses is estimated at the start of each year and tenants pay monthly to spread out the cost over the year. In the above example, if at the beginning of 2021 the landlord over-estimated the increase in property expenses at $60,000, the tenant would pay monthly payments of $1,000 (20% of $60,000 divided by 12 months) totaling $12,000. The tenant thus overpays $2,000. At the end of 2021, the landlord would perform an expense reconciliation resulting in the extra $2,000 being credited back to the tenant.
Municipalities often run on different fiscal calendars than the calendar year. In New York City, the tax year begins on July 1 and ends on June 30 of the following year.
Taxes are typically defined with a catch-all and a list of exclusions, such as:
Sums that the lease already requires the tenant to pay as base rent and additional rent;
Interest or penalties arising from the landlord’s late payment of taxes;
Income, franchise, estate, gift, succession, inheritance, capital-gains, mortgage-recording, transfer, or sales taxes.
The same principles apply to Business Improvement District charges when the premises are located in a BID; those charges should be addressed in a separate provision and should not begin until the year following the base year (or later, if negotiated).
Sample Tax-Escalation Language: “If the Taxes for any Tax Year after the Base Tax Year shall be more than the Base Tax amount, Tenant shall pay as Additional Rent for such Tax Year an amount equal to Tenant’s Share (20% of the total Building) of the amount by which the Taxes for such Tax Year exceed the Base Tax (the ‘Tax Payment’). The Tax Payment shall be prorated, if necessary, to correspond with that portion of a Tax Year occurring within the Term of this Lease. The Tax Payment shall be payable by Tenant within thirty (30) days after receipt of a written invoice from Landlord therefor.”
It is critical to select the most current (or even a future) base year so that the starting point reflects a fully assessed and occupied building. Newly constructed or substantially renovated buildings are especially sensitive: if the base year is artificially low because the increased value has not yet been reflected in the tax assessment, the landlord could lose money, and the tenant can face enormous escalations once the building is reassessed. The parties should therefore set the base year carefully and negotiate a gross-up provision.
If the building has low occupancy during the base year, later increases in occupancy can produce outsized escalations.
With gross-up provisions, landlords calculate tenants’ pro rata share of variable expenses (expenses that vary with occupancy) as if the building were 95% or 100% occupied and all services were being provided to all tenants. This produces a more equitable result for both parties. To avoid future conflict, the parties should consider identifying which expenses will be variable and which will be fixed.
Sample gross-up Language: “If less than 95% of the Building rentable area is occupied by tenants at any time during the Base Operational Year or any other Operational Year, Operating Expenses for such Operational Year shall be an amount equal to the like expenses which would normally be expected to be incurred had such occupancy been 95% throughout the Operational Year, in question, subject to the adjustment set forth above in this paragraph. Notwithstanding anything to the contrary, in no event shall Controllable Expenses (as hereinafter defined) for any Operating Year following the Base Operational Year increase by more than five percent (5%) per Operating Year, on a cumulative and compounded basis. The term “Controllable Expenses” means all Operating Expenses excluding (i) Insurance Expenses, (ii) Utility Expenses, (iii) costs, wages, salaries and other compensation and benefits paid to third parties or Landlord's employees, agents or contractors, (iv) management fees, (v) security, parking and janitorial costs, (vi) weather-related costs, (vii) costs incurred to comply with laws, (viii) costs of capital expenses permitted to be included in Operating Expenses pursuant to the terms hereof, and (ix) costs incurred due to Unavoidable Delays."
* The Lease should define terms such as Base Operational Year, Operating Expenses, and Operational Year
The parties should agree on a deadline for the landlord to furnish statements that constitute a final determination of taxes for the relevant periods, together with a reasonable window (like sixty days) for the tenant to dispute and reconcile the figures.
After the expiration or earlier termination of the term, it is standard to charge a holdover rate of 150%–200% of the last month’s base rent and additional rent. Because of the severe economic impact, tenants often negotiate a tiered structure that rewards prompt cooperation:
Sample Language for a tiered holdover rate provision: “Following Tenant’s default in surrendering the Demised Premises upon the expiration or earlier termination of the Term, Tenant shall pay Landlord, as use and occupancy, 150% of the Monthly Base Rent and Additional Rent due during the last month of the Term for the first thirty (30) days of any such holdover, and thereafter 200% of such amounts for any period of holdover thereafter.”
Electricity is ordinarily the largest utility expense and is billed either by direct meter (tenant contracts directly with the utility) or by sub-meter (landlord reads the meter and bills the tenant at the utility rate plus a modest administrative charge). Notably, the parties should negotiate who pays for the installation of a sub-meter if one is required.
Water, sewer, heat, and gas are less expensive and may be charged as a fixed amount or by meter, depending on expected usage. If usage is low (normal bathroom use), the landlord may absorb the cost in base rent or impose a fixed charge. High-usage tenants are more likely to be metered.
A landlord is obligated to provide only those utilities and services expressly required by the lease. Typical services include electricity, water, heating, air conditioning, passenger and freight elevators (unless the premises are on the ground floor), and sometimes gas, cleaning, and directory listings.
In larger leases, tenants frequently negotiate a response period (commonly three to ten days) after which they receive a rent abatement if the interruption is caused by the landlord and continues. A longer interruption (often thirty days or more) may give the tenant a right to terminate. Landlords usually limit these rights to interruptions that are the fault of the landlord (not the utility company or third parties) and require written notice and an opportunity to cure.
Maintenance disputes are among the most common sources of conflict. Best practice warrants a clear allocation of the responsibility for:
Landlords typically retain responsibility for structural elements, foundations, subflooring, footings, walls, unexposed plumbing, structural elements, and the roof (including its waterproof membrane), and any HVAC, mechanical or electrical equipment not serving the demised premises exclusively. Shared systems require an explicit cost-sharing formula.
Commercial leases commonly distinguish between Building Systems, Structural Elements, and systems exclusively serving the demised premises to allocate repair and maintenance responsibilities between the landlord and tenant.
Building Systems generally include the building's electrical, plumbing, HVAC, fire suppression, life-safety, elevator, and other service systems that support the building as a whole. Because these systems serve multiple tenants or the entire property, the landlord is typically responsible for their maintenance and repair.
By contrast, a tenant is often responsible for systems exclusively serving the demised premises, even if they are part of a larger building system. For example, if an HVAC unit or plumbing line serves only the leased space, the lease may require the tenant to maintain, repair, or replace that equipment. The key distinction is whether the system serves only the tenant's premises or the building generally.
Structural Elements include the roof, exterior walls, foundations, columns, beams, slabs, and other structural components of the building. These elements are generally the landlord's responsibility because they are essential to the building's structural integrity and benefit the property as a whole.
If a tenant wishes to transfer its interest in the entire demised premises for the entire lease term, that is an assignment of the lease. If, however, the tenant transfers only a portion of the premises or for a period of less than the entire lease term, that is a sublet.
New York has no requirement that a commercial landlord be reasonable in denying consent to an assignment or subletting. Landlords commonly reserve the right to withhold consent (even unreasonably) and condition any consent on the absence of monetary or other material default after notice and opportunity to cure. Landlords often set criteria for a suitable proposed assignee (financial statements, banking references, and other information reasonably requested by the landlord). The landlord may also impose restrictions on proposed use of the premises so the use of the demised premises remain the same.
The lease should regulate the tenant’s right to assign or sublet if the business needs to downsize, sell, or restructure. A frequent drafting omission is the failure to treat a change of control as an assignment. That is, even if the lease is not assigned to a different entity, but the ownership of the tenant-entity changes, and the entity controlling the tenant changes, such a scenario also constitutes an assignment.
Sample Change of Control Language: “If Tenant is a corporation, partnership, limited liability company or other business entity, the provisions of this Lease limiting or prohibiting assignment or subletting shall be deemed violated by any transfer, by operation of law or otherwise, of more than fifty-one percent (51%) of any stock, partnership interests, membership interests or other ownership interests of Tenant, whether in a single transaction or a series of related transactions. The issuance of shares of stock to persons other than the existing shareholders shall be deemed a transfer of such stock. The conversion of Tenant or a subtenant to a limited liability company or limited liability partnership shall be deemed an assignment of this Lease or of any sublease.”
From the landlord's perspective, the lease needs to provide that any unauthorized assignment or sublease constitutes irreparable harm, entitling the landlord to immediate injunctive or other equitable relief. The provision should also state that the landlord is not required to post a bond or other security as a condition of obtaining such relief and that the tenant must reimburse the landlord for all attorneys' fees, court costs, and other expenses incurred in enforcing the assignment and subletting restrictions.
Many leases carve out certain transfers that do not require landlord consent or profit-sharing:
Sample Language: “Tenant shall have the right, without Landlord’s consent and without Landlord being entitled to any additional rent or other amounts, to (a) assign its interest in this Lease to any person or entity that is a successor to Tenant by merger or consolidation, or (b) sublease all or a portion of the Demised Premises to (or permit use of all or a part of the Demised Premises by) a person or entity that is an Affiliate of Tenant (each a ‘Permitted Transfer’).”
* The Lease should define the term ’Affiliate of Tenant’, which could be a subsidiary fully owned by the tenant.
While a space can be leased ‘as-is’ but it also may require alteration and build-out. When the space is built out to suit the tenant, leases are highly negotiated and the clauses concerning construction can be lengthy. The tenant will need to retain architects to prepare and review plans and specifications and the landlord will use its own architect to review and approve the plans. The landlord might also designate or qualify specific contractors that are allowed to carry out the build-out or decide that the landlord will perform the build-out.
When the landlord performs the initial build-out, best practice is to annex detailed plans and a work letter specifying materials, brands, quality, colors, and finishes. A clear sequential approval process for Proposed Plans, Revised Plans, and Final Plans, together with tight change-order procedures, dramatically reduces later disputes.
Sample Plan-Approval Process: “Landlord, at its cost, shall cause its architect to complete and submit detailed architectural, structural, mechanical and engineering plans and specifications (including sprinkler plans) for Landlord’s Work (the ‘Proposed Plans’). The Proposed Plans shall be prepared in accordance with this Work Letter and the plans annexed hereto as ‘Plan 1,’ and ‘Material Plan’ (collectively, the ‘Agreed Scope’). Landlord shall deliver the Proposed Plans to Tenant’s architect for review. Within three (3) business days of receipt, Tenant shall approve the Proposed Plans or disapprove them if they are non-conforming with the Agreed Scope, citing the specific reasons. Landlord’s architect shall revise the Proposed Plans within three (3) business days and resubmit them. The process shall be repeated until Tenant’s architect approves the Final Plans.”
Change orders should be subject to landlord approval. As with most provisions requiring landlord consent, Landlords might want to retain their right to unreasonably withhold consent, but the parties might agree that consent to change orders and plans shall not to be unreasonably withheld except for changes that affect structure, building systems, or the appearance or value of the building. The change order should not become binding until the landlord notifies the tenant of the total cost and the tenant accepts that cost in writing and executes the change order.
Sample Plan-Approval Process: “Tenant shall have the right to make changes from time to time to the Final Plans by submitting to Landlord revised plans and specifications (“Change Orders” or a “Change Order”). All Change Orders shall be subject to Landlord's prior approval, which approval shall not be unreasonably withheld, delayed, or conditioned, provided that Landlord may, in the exercise of its sole and absolute discretion, disapprove any proposed changes adversely affecting the Building's structure, any of the Building systems, or the appearance or value of the Building. No Change Order shall be binding on Tenant until Landlord notifies Tenant of the total cost of any proposed Change Order and Tenant notifies Landlord in writing of its acceptance of such cost.”
Allowances are typically structured as a dollar amount per square foot or a fixed total cap, paid upon production of paid invoices, and often convert unused amounts into rent credit or are forfeited. The lease should specify eligible costs, payment timing, and treatment of unused funds.
When the allowance is for specific, distinguishable items such as furniture, the lease could provide that the items become the property of the landlord and that the landlord has no obligation to repair, replace, or insure them.
Building standards are often defined by reference to an existing floor or unit in the same building (for example, “the finishes, materials, fixtures, appliances, equipment and components existing as of the date of this Lease on the third floor”). Work above building standards is charged to the tenant as excess construction cost. Landlords should retain the right to refuse changes that would materially delay Substantial Completion.
Tenants might ask that any out-of-pocket costs that Tenant will incur shall only be incurred after Landlord first provides a detailed, itemized written estimate (including a description of the work and any third-party charges) and Tenant expressly approves such costs in writing. Landlord shall not commence nor authorize any work to be performed or incur any such costs prior to receiving Tenant’s written approval.
One effective way to control tenant improvement costs is to require the landlord to obtain an initial competitive quote while allowing the tenant to solicit independent bids from qualified contractors. The tenant can then elect which quote will govern the work, with the landlord obligated to engage the selected contractor or otherwise honor the selected pricing. Coupled with a requirement that the landlord obtain the tenant's prior written approval before incurring any costs, this mechanism creates pricing transparency, encourages competitive bidding, and reduces the risk of inflated construction charges.
This concept can be extended to virtually any reimbursable tenant expense. Lease provisions can permit the tenant to obtain competing quotes for flooring, signage, security systems, telecommunications infrastructure, furniture, fixtures and equipment, specialty finishes, architectural and engineering services, and other construction or maintenance costs. By incorporating a consistent competitive-quote and prior-approval process across these categories, tenants gain greater control over project expenditures while landlords retain oversight of the work and coordination of the construction process.
Sample Language: "Landlord shall perform the installation of such flooring, with Tenant reimbursing Landlord for the full cost, subject to the Cap and the following provisions. Landlord’s architect shall obtain a written, itemized quote for the performance of the foregoing scope of work from a licensed contractor based on the current design (“Landlord’s Flooring Quote”) and shall send same to Tenant. Tenant shall have the right, but not the obligation, to obtain one or more independent quotes from other licensed contractors for the installation of such flooring, and Tenant may elect, in its sole discretion, to select and approve any such other licensed contractor (“Tenant’s Flooring Quote”) in lieu of the Landlord’s Flooring Quote. Tenant shall notify Landlord as to its selection of either the Landlord’s Flooring Quote or the Tenant’s Flooring Quote. Landlord agrees to use the licensed contractor under the Landlord’s Flooring Quote or the Tenant’s Flooring Quote, as indicated by Tenant, for the performance of such flooring and Tenant shall only be responsible for the approved amount of the selected quote, and Landlord shall not commence work or incur any related costs unless and until Tenant has provided prior written approval of either the Landlord’s Flooring Quote or the Tenant’s Flooring Quote. Prior to commencing any fabrication or installation work, Landlord shall confirm with Tenant the specifications for all materials, including but not limited to the type, quality, and color of flooring to be used. Tenant shall have the sole option to elect the supplier for the flooring materials and Landlord shall cooperate to effectuate Tenant’s selection in a timely manner."
* The Lease should define the term ’Cap’, which sets the maximum reimbursement to the Landlord.
These dates must be carefully distinguished:
Target Date / Estimated Delivery Date: the parties’ estimated date for delivery after build-out; used for logistics and delay penalties.
Substantial Completion: delivery of the premises with Landlord’s Work completed so that Tenant can occupy and conduct business, subject only to minor punch-list items.
Possession Date: the date the premises are delivered to the tenant broom-clean with Landlord’s Work Substantially Complete.
Lease Term Commencement Date: usually the Substantial Completion date, provided exclusive possession has been delivered, the fully executed lease has been exchanged, and Tenant has paid the amounts due on execution (security deposit, first month’s rent, etc.).
Rent Commencement Date: the date on which rent actually begins; often later than the Lease Term Commencement Date to reflect a rent concession for the build-out period.
Delays caused by back-ordered materials selected by Tenant, Tenant change orders, or other Tenant-caused delays should not postpone the Lease Term Commencement Date or the Rent Commencement Date. Tenants often negotiate a day-for-day rent abatement for landlord delays beyond an outside Target Date. After delivery, the parties should execute a Lease Commencement Certificate confirming the actual commencement dates, the expiration date, completion of Landlord’s Work, and the final rent schedule (including application of any concessions).
An Early Access Period of approximately thirty days before commencement is common for installation of IT wiring, furniture, fixtures, and equipment, subject to restrictions (no commencement of Tenant’s Work, limited insurance requirements, etc.).
Commercial leases typically require the tenant to submit plans and specifications for any alterations, improvements, or installations to the landlord for prior written approval, unless the lease expressly excludes certain Permitted Work or other non-material changes from the approval requirement. Landlords often demand that all the tenant’s work comply with applicable building codes, permits, laws, and governmental regulations.
For the review and approval of Tenant's plans and specifications, Landlord might charge the tenant for reasonable architectural, engineering or other professional fees that Landlord incurred up to a certain cap. Landlord will also likely require:
A mechanic’s lien is a legal claim that contractors, subcontractors, or material suppliers can file against the building when they are not paid for work or materials supplied to the tenant’s premises. Even though the work was ordered by the tenant, the lien attaches to the landlord’s property and can cloud title, interfere with refinancing, or delay a sale. Commercial leases therefore require the tenant to discharge any such lien (by payment, bonding, or otherwise) within a short period, commonly 30 days, after notice from the landlord. If the tenant fails to do so, the landlord may clear the lien at the tenant’s expense and recover all costs, including legal fees, as additional rent.
Sample Language: “If any mechanic’s lien shall be filed against the Building for work claimed to have been done for, or materials claimed to have been furnished to, Tenant, the same shall be discharged by Tenant, by payment, bonding or otherwise, at Tenant’s sole cost and expense, within thirty (30) days after written notice from Landlord. If Tenant fails to discharge the lien within such period, Landlord may discharge it at Tenant’s expense and Tenant shall reimburse Landlord, as Additional Rent, for all costs (including legal fees) incurred, together with interest.”
At a minimum, landlords require commercial general liability insurance and personal-property insurance. Flood insurance may be required if the building is in a flood zone. From the landlord’s perspective, consulting a licensed insurance broker about the building’s valuation, risk profile, and the tenant’s operations helps set appropriate minimum coverage limits.
Landlords should reserve the right to demand certificates of insurance (or the full policy) at any time. Failure to maintain required coverage is typically a default entitling the landlord to terminate. Best practice is to require that the landlord, its property manager, and any mortgagee be named as additional insureds on a primary and non-contributory basis.
An indemnity clause shifts legal responsibility for claims arising from the tenant’s use of the premises. In a multi-tenant building with shared elevators, lobbies, and systems, clear indemnity language is essential to keep the landlord from being drawn into lawsuits that properly belong to the tenant’s insurance.
If the tenant’s business requires a specific governmental license or permit (liquor license, hotel license, daycare license, etc.), the tenant may ask for a contingency under which the lease shall not take effect if the license is not obtained despite the tenant’s commercially reasonable efforts. Landlords typically require proof of those efforts (professional applications, correspondence with the agency, etc.).
Retail tenants often seek exclusivity provisions that prohibit the landlord from leasing space in the same building (or a defined geographic radius) to direct competitors. Landlords should limit the scope of any exclusivity, carve out existing tenants, and define “competitor” narrowly to preserve flexibility for future leasing.
For shopping centers, strip malls, and similar retail properties, landlords may also seek reciprocal protections by restricting certain anchor tenants or major retailers from opening additional locations within a specified geographic area. These limitations can help preserve the property’s market position, prevent internal competition among tenants, and protect the value and customer base of the shopping center.
A default occurs when either party violates a material term of the lease. A well-drafted lease should distinguish monetary defaults (failure to pay rent or additional rent) from non-monetary defaults (failure to maintain insurance, unauthorized alterations, etc.) and provide different notice-and-cure periods. Landlords are less likely to agree to notice of monetary defaults because the tenant already knows when rent is due; they are more likely to agree to notice and a reasonable cure period (5–14 days) for nonmonetary obligations, such as repairs, nuisance, failure to produce a copy of the insurance policy, etc.
Peaceable self-help remains available in commercial contexts under limited circumstances, but landlords should still draft clear notice provisions and consult counsel before acting.
A conditional limitation provision allows a landlord to terminate a lease upon the occurrence of certain tenant defaults, including situations involving repeated defaults or an ongoing uncured default. The purpose of such a provision is to protect the landlord where a tenant’s failure to satisfy its obligations demonstrates a significant risk to the landlord’s financial interests or the continued viability of the lease relationship.
From the landlord’s perspective, there may come a point where unpaid rent or other charges become so substantial that the likelihood of repayment is significantly reduced, and the tenant may ultimately seek bankruptcy protection, leaving the landlord with limited ability to recover outstanding amounts. A conditional limitation provision provides the landlord with the ability to terminate the lease rather than remain indefinitely bound to a financially distressed tenant, while preserving the landlord’s rights to pursue unpaid rent, damages, and other remedies available under the lease.
Landlords commonly require the tenant to execute an estoppel certificate in the form attached to the lease; failure to do so is a default and grounds for termination.
An estoppel certificate is a written statement signed by the tenant confirming key facts about the lease, such as that it is in full force, there are no defaults, rent has been paid through a stated date, and the tenant has no claims or offsets. Landlords (and their lenders or buyers) rely on these certificates. Landlord should protect against tenants’ delays or failures in delivering a timely and accurate estoppel certificate by stipulating in the lease that such delay or failure constitutes a material breach.
Typical language provides that neither the cancellation of any ground lease nor the foreclosure of any mortgage shall result in the termination of the lease, and that the tenant will attorn to and recognize any successor landlord or mortgagee upon request. Landlords may agree to use commercially reasonable efforts to obtain a Subordination and Non-Disturbance Agreement (SNDA) from present or future lenders, but should not be held responsible if the lender refuses.
People often confuse an SNDA with an estoppel certificate because lenders request both at the same time.
This clause limits the landlord’s liability to its interest in the Building. The tenant may look only to that property for any judgment; the directors, officers, shareholders, and agents of the landlord entity, and the landlord’s other assets are protected.
The parties should expressly name the brokers they used and provide mutual indemnities against claims by any undisclosed broker.
The landlord typically controls building-standard lobby and floor signage and provides the Tenant with signage consistent with other office or retail tenants of comparable size.
A Yellowstone injunction is a specific type of court order in New York that pauses the clock on a commercial lease while a tenant disputes a landlord's claim that they violated the lease.
Courts hold up waivers of Yellowstone injunctions. See 159 MP Corp. v. Redbridge Bedford, LLC, 160 A.D.3d 87 (2d Dep’t 2018) (Second Department denied the tenant’s motion for a Yellowstone injunction since the tenant has waived that right in the lease).
Sample language for a “Yellowstone” injunction:
"(A) Tenant acknowledges that Owner’s receipt of all fixed rent and additional rent when first due from Tenant pursuant to this Lease is an essential term of this Lease. Accordingly, Tenant agrees and consents that if Tenant at any time seeks a “Yellowstone” injunction (First National Stores, Inc. v. Yellowstone Shopping Centers, Inc., 21 N.Y.2d 630 [1968]) from a court of competent jurisdiction, then such relief shall not be granted unless, at a minimum, the following items are fully complied with:
(i) Tenant will advise the court in its motion papers seeking such Yellowstone relief of the existence of this Lease clause;
(ii) Any affidavit or affirmation submitted by Tenant in support of such a Yellowstone motion will include: (a) an express request that the Yellowstone Injunction being sought be conditioned, at a minimum, on Tenant both being current in the payment of fixed rent and additional rent to Owner and continuing, each and every month during the period of any Yellowstone injunction, and Tenant making monthly fixed rent and additional rent payments to Owner as required by this Lease; and (b) an express statement that payment of said amounts into escrow would be inadequate and is not what Tenant seeks; and
(iii) Any order to show cause submitted by Tenant to any court in connection with, or as part of, its Yellowstone motion will include provisions conditioning both interim and ultimate relief on: (a) Tenant both being current in payment of fixed rent and additional rent to Owner and continuing, each and every month during the period of any Yellowstone relief; (b) Tenant making monthly fixed rent and additional rent payments to Owner as required by this Lease.
(B) It is further agreed that in the event injunctive relief is sought, or if a “Yellowstone” is sought, by the Tenant with respect to any provision of the Lease, or with respect to any notice sent pursuant to the provisions of this Lease, the Owner shall be entitled to recover the costs of opposing such an application or action, including its attorneys’ fees actually incurred. Tenant shall not apply for any ex parte order for any relief under this Lease without first advising Owner in writing on 24 hours’ notice of the time and place of such application."
Commercial leases typically allocate responsibility for asbestos and other hazardous materials based on which party caused, introduced, or disturbed the hazardous condition. Landlords are generally responsible for hazardous materials existing in the building prior to the tenant’s occupancy, while tenants are responsible for ensuring that their use of the premises does not cause contamination or violate applicable environmental laws.
Tenants are commonly prohibited from using, storing, or disposing of hazardous substances except as permitted by law. If the tenant’s work, alterations, or conduct cause contamination or require remediation, the tenant is typically responsible for all investigation, cleanup, removal, and restoration costs, as well as indemnifying the landlord for related claims and expenses. Conversely, if the landlord causes contamination after the lease commencement date, the landlord may be responsible for remediation and resulting liability. Lease provisions should clearly define responsibility for hazardous materials, including compliance, remediation, and indemnification obligations.
Landlords typically resist granting a right of first refusal (ROFR) because it can deter potential buyers or lenders: any third party must first make an offer and then wait for the tenant to match it. For tenants, however, a ROFR (or a right of first offer) can be strategically important when long-term control or eventual ownership of the space is a priority.
Tenants may also seek expansion rights that allow them to lease additional contiguous or nearby space in the building as it becomes available. When such rights are granted, best practice is to record a short-form memorandum of lease that discloses the ROFR, right of first offer, or purchase option. Recording puts third parties on constructive notice and prevents a subsequent buyer from claiming bona fide purchaser status.
A carefully drafted commercial lease is the primary risk-allocation and revenue-protection instrument for both landlords and tenants in New York City. Landlords who insist on precise permitted-use language, clear escalation and gross-up formulas, robust assignment and change-of-control provisions, detailed work letters, and practical interruption and default clauses protect both current cash flow and the long-term value of the asset.
Whether you are a landlord preparing to market space, renewing an existing tenancy, or evaluating a letter of intent from a prospective tenant, early legal review of the form lease and the term sheet is the most cost-effective way to avoid disputes and protect your investment.
