The 50 Most Dangerous
Commercial Lease Clauses

CPI exceeded 8% in 2022 and 6% in 2021. An uncapped CPI escalator can double your rent within 10 years.

Without a natural breakpoint, you pay percentage rent from dollar one of sales — even on revenues that barely cover your operating costs.

Without an audit right, you have no way to verify the landlord's reconciliation calculations.

Without exclusions, landlords can pass through capital expenditures, management fees above market, their own overhead, and costs for tenant improvements for other tenants.

A gross-up provision allows the landlord to charge you as if the building were fully occupied — even when it's 40% vacant and costs should be proportionally lower.

Without a CAM cap, operating expenses can increase by any amount in any year — passing unlimited cost inflation to the tenant.

Without a renewal right, your landlord can refuse to renew or demand any rent increase at expiration. Without a defined rate formula, the "market rate" is whatever the landlord says it is.

Missing the exercise deadline by a single day causes permanent loss of the renewal right — there is typically no grace period.

Without a termination option, you are locked into rent payments through the full term regardless of business changes — acquisition, downsizing, remote work adoption.

An unlimited personal guarantee exposes your personal assets (home, savings, investments) to liability for the full remaining rent if your business fails.

The good guy guarantee protects you — if you give proper notice and surrender in good condition, liability ends. But a 90-day notice requirement means 90 days of rent after you've decided to exit.

A 3-day cure period for missed rent gives you almost no time to respond — a bank wire delay, a payroll cycle timing issue, or a simple administrative error can trigger a default.

Non-monetary defaults (violations of use clauses, signage requirements, maintenance obligations) can be complex to cure — a 0-day cure period is unreasonable.

If you negotiate a great lease at below-market rent and the market rises, a profit recapture clause means the landlord takes half of any sublease premium you've earned.

A recapture right means the landlord can terminate your lease and deal directly with your proposed subtenant — taking your assignment or sublease economics away from you entirely.

"Building standard" has no defined meaning — it could be $10/SF of paint and carpet or $60/SF of quality finishes. Without a dollar figure, you can't budget your build-out.

If TI is only disbursed after complete lien waiver delivery, you may need to fund the entire build-out from your own capital upfront and wait 60–90 days for reimbursement.

"Original condition" is undefined. After a major build-out, "original condition" restoration could mean demolishing everything you built — a six-figure cost.

A self-help right with minimal notice allows the landlord to enter your space, perform work, and charge you for it — including work you dispute is your obligation.

"Regardless of the cause" means you're indemnifying the landlord even for their own negligence — which your general liability insurance may not cover.

If the landlord can choose whether to restore, they may opt to terminate your lease after a fire — even if the damage is minor — if they want the space back.

If your space burns down and the landlord spends 6 months restoring it, you may owe full rent throughout the restoration period if no abatement provision exists.

A narrowly defined use clause requires landlord consent for any change in business — adding a product line, pivoting the model, or operating a different business type after an acquisition.

Without exclusivity, the landlord can place your direct competitor in the suite next to you — regardless of how long you've been there.

A continuous operation clause prevents you from temporarily closing — for renovation, seasonal slowdown, or business model transition — without being in default.

Any holdover — even a few days while a new lease is being finalized — triggers a 100% rent premium on the entire month.

Without an SNDA, the landlord's lender can terminate your lease in a foreclosure — even if you're current on rent and in perfect compliance.

Five business days is extremely short to review an estoppel certificate with counsel, identify any factual inaccuracies, and respond appropriately.

A landlord relocation right can displace your business mid-lease — disrupting operations, invalidating signage, and destroying location-dependent business relationships.

Without documented parking rights, the landlord can reduce or eliminate your parking access — or charge additional fees — without breaching the lease.

An uncapped force majeure provision can excuse the landlord from delivering your space, completing repairs, or providing services for unlimited time.

Without documented signage rights, the landlord controls all signage decisions — including your suite identification, building directory listing, and exterior visibility.

If you assign your lease as part of a business sale, your personal guarantee continues to cover the new tenant's obligations — indefinitely, for modifications you never agreed to.

An automatic default triggered by bankruptcy filing may conflict with the automatic stay provisions of the Bankruptcy Code — but it signals the landlord's intent to use insolvency as a basis for lease termination.

Without a right to cure, a technical default (missed payment, insurance lapse) allows the landlord to immediately pursue eviction and damage remedies.

Most states require landlords to mitigate damages (re-let the space), but an express lease provision can contractually limit or waive this duty.

Without notice, you won't know your deposit has been applied until you receive a demand to replenish — potentially triggering a technical default.

When a lease says the tenant must "maintain in good repair" without specifying HVAC, it's ambiguous whether HVAC maintenance and replacement is the tenant's or landlord's responsibility.

Unlimited landlord discretion on assignment consent can block business sales, mergers, acquisitions, and succession planning.

Annual RSF re-measurement can increase your rent even if your actual space hasn't changed — through variations in measurement methodology.

A technical default (insurance lapse, signage violation) that triggers the full guarantee can expose your personal assets to the entire remaining lease liability.

Without offset rights, even if the landlord breaches material obligations (HVAC failure, roof leak, common area neglect), you must continue paying full rent while pursuing your claims separately.

Without a definition of "change of control," any ownership change — including a startup receiving Series A funding — could technically require landlord consent.

Without a base year, you pay all taxes from dollar one — including any assessments that occur after you sign but before you move in.

If a major anchor tenant goes dark, foot traffic drops — and you have no rent relief or termination right without a co-tenancy clause.

Insurance requirements exceeding standard commercially available policies force tenants to pay premium rates for excess coverage that may not be commercially necessary.

A demolition clause allows the landlord to force you out mid-lease for any planned redevelopment — with limited notice and no obligation to provide replacement space.

Modern businesses operate outside 8–6 M-F. Without documented 24/7 access rights, after-hours entry requires landlord permission.

Requiring consent for every change — even painting walls or hanging whiteboards — creates operational friction and delays minor workplace improvements.

Landlord showing rights during the final year give the landlord access to your operations, customers, and business information — and constant disruption from showings.
