Commercial Lease Red Flags: 15 Terms to Watch Before You Sign

A commercial lease agreement is not a standard form; it’s a negotiated contract, and every clause in it was written by someone with an incentive. In most cases, that someone was the landlord’s attorney. The result is a document that, in its default form, systematically transfers risk from the landlord to the tenant: cost exposure, operational restrictions, exit barriers and personal liability that most business owners don’t fully understand until they’re locked into a ten-year term with no good options. The stakes are unusually high. A single overlooked clause can mean paying above-market rent with no remedy, losing your space mid-lease without cause, or finding yourself personally on the hook for hundreds of thousands of dollars when a business relationship ends badly. The right time to find and fix these problems is before you sign, not after.

This guide identifies 15 of the most consequential commercial lease red flags that Hughes Marino’s tenant representation team encounters most frequently in commercial lease negotiations. Each represents a clause that is routinely included in landlord-drafted leases, routinely accepted by tenants without scrutiny, and routinely correctable, if you know what you’re looking for and have the right advisor in your corner. We’ve also included specific lease negotiation counter-terms for the five highest-risk clauses, so you walk into every negotiation with a clear target, not just a list of problems. Whether you’re reviewing an office lease, laboratory space, an industrial facility or any other commercial property, these are the provisions that deserve your closest attention.

 

Hughes Marino’s Commitment to Transparent Tenant Representation

Hughes Marino represents tenants and occupiers, not landlords. That singular focus matters most at the lease negotiation stage, because the advisor who reviews your commercial lease brings either a tenant’s perspective or a landlord’s perspective to every clause. A large brokerage firm that also manages properties, handles landlord leasing and sells investment real estate has structural reasons to preserve landlord-friendly language that a pure tenant representative does not.

Our team has reviewed tens of thousands of commercial leases for our clients around the globe. The 15 most common red flags to watch out for below are not theoretical; they are the clauses we renegotiate most often, the provisions that cost our clients the most when they go unchallenged, and the language that landlords’ attorneys count on tenants to accept without question. While the below topics are most common, there are often 100+ idiosyncratic issues to negotiate in order to properly protect tenants. If you have an existing lease and are not certain what it actually says on any of these points, a lease audit is the most efficient first step. If you are approaching a renewal or a new lease, the time to identify and address these provisions is now, before any terms are agreed to verbally and before you’re negotiating from a position of reduced leverage.

 

1. Financial Red Flags: Personal Liability, Rent Structures and Escalations

The financial provisions of a commercial lease determine not just what you pay, but who bears the risk when business conditions change. These are the clauses most likely to produce catastrophic outcomes for business owners who didn’t fully read what they signed.

Red Flag #1: The Unlimited Personal Guarantee

A personal guarantee requires an owner or officer to back the company’s lease obligations with their personal assets. In a landlord-drafted lease, the guarantee is typically unlimited, covering the full financial exposure of the entire lease term, with no sunset or mitigation provision. That means if your business closes in year three of a ten-year lease, you remain personally liable for seven more years of rent obligations. The negotiated alternative is a burn-off guarantee: personal liability that reduces or expires after a defined period of consistent on-time rent payment (typically 12 to 24 months), and is capped at a fixed dollar amount (typically 6 to 12 months of base rent) rather than the full remaining term. Landlords who want creditworthy tenants will accept this. The ones who refuse to negotiate personal guarantee terms are showing you something about how they expect the tenancy to go. Your advisor plays a substantial role in how this provision gets negotiated.

Red Flag #2: A Fixed Rent Schedule with No Renewal Market Reset Mechanism

Commercial leases, especially long ones, should include a mechanism for resetting rent to market if conditions shift significantly. A lease that locks in today’s rent on a fixed escalation schedule for 10 or 15 years means you could be paying substantially above-market rates by year eight with no contractual remedy. Push for a fair market value rent reset option at renewal, defined by a third-party appraisal process with binding “baseball” arbitration if the parties disagree. This is standard in well-negotiated leases and something most landlords will accept when pressed.

Red Flag #3: Uncapped Annual Rent Escalations

Most commercial leases include annual rent increases tied to either a fixed percentage (typically 3%) or the Consumer Price Index. The CPI-linked version is the more dangerous of the two, because CPI has no ceiling. In a high-inflation environment, a CPI-based escalation clause can push rent increases above 8 to 10% in a single year with no protection for the tenant. Negotiate a cap on annual escalations, typically 3 to 4% per year regardless of CPI movement, as a hard ceiling on your year-over-year rent exposure.

 

2. Expense Exposure Red Flags: CAM, Gross-Ups and Capital Pass-Throughs

For tenants in NNN (triple-net) or modified-gross lease structures, operating expense provisions are where the financial exposure often hides. The base rent may be competitive, but the total occupancy cost can be dramatically higher once operating expense pass-throughs are factored in, especially in aging buildings with deferred maintenance or in markets where landlords routinely push the boundaries of what expenses can legitimately be passed through.

Red Flag #4: Uncapped CAM and Operating Expense Pass-Throughs

Common Area Maintenance (CAM) and operating expense clauses in NNN leases can pass through virtually every building operating cost to tenants: property taxes, insurance, maintenance, management fees, utilities and more. Without a cap, your occupancy cost is unpredictable from year to year. Caps aren’t standard for most tenants, but they are negotiable: push for a year-over-year CAM increase cap of 3 to 5% on controllable expenses (those within the landlord’s ability to manage). This doesn’t limit total operating costs; it limits how fast they can grow in any given year, which is what matters for your budget certainty.

Red Flag #5: Gross-Up Provisions

When a building is partially occupied, the landlord’s actual operating expenses are lower than they would be at full occupancy. A gross-up provision allows the landlord to calculate what expenses would have been at 95% or 100% occupancy, and charge tenants their pro-rata share of what could be an inflated number – rather than the actual number. In a soft market with significant vacancies, this can result in tenants paying thousands of dollars per year in phantom expenses the landlord never actually incurred. It is important to understand whether a gross-up provision can save or cost you money, as it depends on many factors.

Red Flag #6: Capital Expenditure Pass-Throughs

Routine maintenance is a legitimate operating expense that tenants in NNN leases should expect to share. Major capital expenditures shouldn’t be a tenant’s responsibility, but often are. A landlord-drafted lease will often attempt to pass through the cost of HVAC system replacement, roof replacement, parking lot resurfacing, mold mitigation or elevator modernization as operating expenses, amortized over time, but still billed to current tenants who will never occupy the building long enough to benefit from the improvement. Negotiate explicit exclusions for capital expenditures exceeding a defined dollar threshold (typically $10,000 to $25,000 per occurrence) from the operating expenses you are responsible for as a tenant.

 

3. Control and Flexibility Red Flags: Relocation, Exclusivity and SNDA

Some of the most consequential lease provisions are not about what you pay; they’re about the security of your right to occupy the space you’ve invested in, and whether you have the operational flexibility your business actually needs. These clauses are frequently buried in the middle of long leases and passed over without full consideration.

Red Flag #7: Landlord’s Right to Relocate Your Business

A relocation clause gives the landlord the right to move your business to a different suite or floor within the building, typically with 30 to 90 days’ notice. This provision exists primarily to give the landlord flexibility to accommodate larger tenants or reconfigure floors. For the tenant, it can mean an unplanned move mid-lease with real cost implications: new signage, new office materials, client notification, IT reconfiguration and potential damage to carefully cultivated adjacency relationships. The solution is to negotiate for the relocation clause to be removed entirely, or conditioned on your written consent plus full reimbursement of all documented relocation costs.

Red Flag #8: Exclusivity Clauses with Too Many Carve-Outs

If your business depends on being the only provider of your product or service category in a building or shopping center, an exclusivity clause is essential. The problem is that most landlord-drafted exclusivity provisions are riddled with exceptions: existing tenants and their renewals are excluded, franchises are excluded, incidental sales are excluded and online or delivery operations may be excluded entirely. Read the exclusivity clause carefully and test every carve-out against real scenarios. A competitor who secures space in your building under the “existing tenant renewal” exception is just as damaging as one who signs a new lease.

Red Flag #9: No Non-Disturbance Agreement (SNDA)

A Subordination, Non-Disturbance and Attornment (SNDA) agreement does three things: it confirms your lease is subordinate to the landlord’s mortgage, it protects your right to remain in occupancy if the lender forecloses, and it commits you to recognize a new owner as your landlord. The critical piece for tenants is the non-disturbance commitment: the lender’s agreement that if they take title to the building, your lease will remain in force. Without it, a lender who forecloses can potentially terminate your tenancy even if you are current on rent. Require an executed SNDA from the existing lender before you take possession, and require that future financing be similarly conditioned on non-disturbance protection for your tenancy.

 

4. Exit and Transfer Red Flags: Subleases, Demolition and Holdover

Business conditions change. Companies grow, contract, restructure, merge and occasionally fail. A commercial lease that was appropriate for your business on day one may become a significant liability if it doesn’t allow you the flexibility to adapt your space commitment when circumstances shift. The clauses in this category determine whether your lease is a manageable obligation or a trap.

Red Flag #10: Restrictive Sublease and Assignment Provisions

Most commercial leases require landlord consent before you can sublease your space to another party or assign your lease in connection with a business sale or merger. That consent provision is standard, but the conditions under which it can be withheld, and the economic terms attached to it, vary enormously. Landlord-drafted leases typically allow the landlord to recapture the space if you want to sublease (taking the space back and re-leasing it at market), share in any sublease profit above your base rent, or withhold consent with minimal justification. Push for consent that cannot be unreasonably withheld, no recapture right and no profit sharing on sublease premium, especially for subleases covering less than your full footprint.

Red Flag #11: The Demolition or Recapture Clause

A demolition clause (sometimes called a redevelopment or recapture clause) gives the landlord the right to terminate your lease early if they decide to demolish, substantially renovate or redevelop the building. The notice period is typically 6 to 12 months, enough time to create serious disruption but rarely enough to find, negotiate, build out and occupy a comparable space without gaps. This clause is particularly dangerous for tenants with significant build-out investments, because all of that investment is lost when the landlord exercises the right. If you cannot get the clause removed, insist on a minimum notice period of 18 to 24 months, full reimbursement of unamortized tenant improvement allowances and moving costs, and a right of first refusal on any comparable space in the redeveloped property.

Red Flag #12: Extreme Holdover Rent Penalties

A holdover clause governs what happens if you remain in your space beyond the lease expiration date without executing a renewal or new lease. Landlord-drafted holdover provisions often set the holdover rent at 150 to 200% of the then-current base rent, payable month-to-month, plus the landlord’s right to recover consequential damages, meaning if another tenant wanted the space and couldn’t get it because you held over, the landlord can sue you for that lost deal. The more reasonable standard, which experienced tenant advisors negotiate routinely, is 100 to 125% of base rent for a defined short period (60 to 90 days), with consequential damages limited to situations where the landlord has an executed lease with an incoming tenant.

 

5. Structural Protection Red Flags: Delivery Condition, Repairs and Renewal Options

The final category of commercial lease red flags relates to the physical condition of the space you’re taking, the obligations you’re assuming for its maintenance, and the mechanism by which your lease continues or ends. These provisions are often dismissed as “boilerplate,” which is precisely why landlords’ attorneys leave them in the most landlord-favorable form possible.

Red Flag #13: “As-Is” Delivery with No Defined Condition Standard

An “as-is” delivery clause means you accept the space in its current condition, with no representations by the landlord about its fitness for use, compliance with applicable codes or the condition of building systems. In a space that has recently been vacated, “as-is” can hide deferred HVAC maintenance, ADA compliance deficiencies, code violations, environmental conditions or simply poor cosmetic conditions that you will be required to bring up to standard at your expense. Before accepting any as-is delivery, negotiate a landlord warranty that the building systems (HVAC, plumbing, electrical and life safety) will be in good working order on the delivery date, for a defined period after you take possession, and require that the landlord bring the premises and base building into compliance with applicable codes, including the ADA, at the landlord’s cost. Do not accept as-is delivery blindly.

Red Flag #14: Tenant Responsibility for Structural Repairs and Building Systems

In a well-balanced commercial lease, the landlord retains responsibility for the building structure (roof, foundation, exterior walls) and the major building systems (HVAC, plumbing, electrical), while the tenant is responsible for their own interior improvements. Landlord-drafted leases sometimes attempt to shift HVAC maintenance, repair and even replacement obligations to the tenant, particularly for units that are “dedicated” to the tenant’s suite. Over a long lease term, HVAC system replacement alone can cost $20,000 to $50,000 or more per unit. Negotiate to clearly delineate landlord vs. tenant maintenance obligations in writing, with major systems (HVAC, plumbing, electrical) remaining the landlord’s responsibility for repair and replacement, and tenant obligated only for routine maintenance.

Red Flag #15: Missed Renewal Option Deadlines

Most commercial leases don’t renew automatically. Instead, renewal is a tenant option that must be exercised by written notice within a specified window, often 6 to 12 months before expiration. Miss that deadline and the option is typically lost, leaving you to negotiate a renewal with little leverage or to relocate on a compressed timeline. Option deadlines are often buried in the lease body rather than highlighted in any summary. Calendar every option and notice deadline from day one of your lease, negotiate a clearly defined exercise procedure, and ask for a provision requiring the landlord to notify you before the option lapses. Most importantly, don’t wait for the deadline: begin evaluating your renewal and alternatives 18 to 24 months before expiration, while you still have time and leverage.
