Lease Horror Stories: 8 Commercial Lease Clauses That Haunt Tenants — Blog Header

1. CAM reconciliation

The bill that rises from the grave

A bakery budgets for its monthly common area maintenance (CAM) estimate. In spring, a reconciliation statement arrives saying last year's actual costs ran higher, and it owes the difference in one lump sum.

What is a CAM reconciliation?

In most net and modified gross leases, you pay a monthly estimate of your share of building expenses (see how lease structures affect your rent). After year-end, the landlord compares estimates to actual costs and bills or credits the difference. Most landlords send prior-year reconciliations in the second quarter, and according to Hughes Marino, "most of the overage will be paid by the tenants in the building."

How to negotiate it

  • A cap on annual increases in controllable expenses such as repairs, payroll and management fees
  • A clear list of what is excluded from CAM, such as capital improvements and the landlord's own leasing costs
  • The right to audit the landlord's books, with the landlord paying for the audit if it finds a meaningful overcharge
  • A deadline for the landlord to send the reconciliation, after which it cannot bill you

2. Personal guarantee

The curse that follows you home

A small agency's LLC signs a 5-year lease. The owner also signs a personal guarantee. Two years in, the business closes, and the landlord sues the owner personally for the remaining rent.

What is a personal guarantee?

As FindLaw puts it, a personal guarantee "makes you personally liable for rent if the business can't pay."

How to negotiate it

  • Good guy guarantee: your liability ends once you give the required advance notice (often 90 to 180 days), vacate properly and are current on rent through your move-out date
  • Burn-off: the guarantee expires after a set period of on-time payments, such as two years into a five-year lease
  • Dollar cap: limit the guarantee to a fixed amount, such as 6 or 12 months of rent
  • Offer something else: a larger security deposit or letter of credit in place of a guarantee

3. Relocation

The landlord who moves your furniture

A medical practice builds out a suite with plumbing in every exam room. The landlord signs a larger tenant who wants the whole floor and invokes the relocation clause.

What is a relocation clause?

A relocation clause lets the landlord move you to other space in the building, or sometimes another property it owns. A sample clause analyzed by Thompson Coburn gives the landlord that right "upon at least one hundred eighty (180) days' prior written notice."

How to negotiate it

  • Delete it entirely, which is most realistic for larger or specialized spaces
  • Define comparable space: same size or larger, same floor or better, same building
  • Require the landlord to pay all moving, build-out, IT, signage and reprinting costs
  • Keep the same rent, or lower it if the new space is smaller
  • Ban relocation during your busy season or in the last year of the term

4. Holdover

The lease that will not let you leave

A distribution company's new warehouse is delayed by permitting. It stays in its old space two extra months, and rent jumps by half.

What is holdover rent?

If you stay past your lease expiration without a new agreement, holdover rent applies. According to Epstein Becker Green, most commercial leases set it at 150% to 200% of the monthly base rent paid before expiration. Some leases also make you liable for the landlord's losses if a new tenant cannot move in.

How to negotiate it

  • Lower holdover rent, such as 125% to 150%
  • A grace period of 30 to 60 days at the regular rate or a smaller increase
  • No liability for consequential damages unless the landlord gave you written notice of a signed replacement tenant
  • Start your relocation search 12 to 18 months before expiration so holdover never happens

5. Restoration

The build-out you pay for twice

A fitness studio spends heavily on rubber flooring, showers and soundproofing. At move-out, the landlord requires it all removed and the space returned to its original condition, at the tenant's cost.

What is a restoration clause?

Restoration and surrender clauses define what condition you must leave the space in. Many say little more than "broom-clean," which does not settle who removes cabling, fixtures, racking or structural changes.

How to negotiate it

  • List, at signing, exactly which improvements must be removed. Everything else stays.
  • Require the landlord to say whether an alteration must be removed when it approves the alteration, not at move-out
  • Exclude standard office improvements and cabling from removal
  • Cap restoration costs or tie them to your security deposit

6. Notice deadlines

The window that slams shut

A software company has a renewal option at a fixed rate. The lease requires written notice 9 months before expiration. They send it at 7 months, lose the option, and renegotiate at market rent with no leverage.

What are lease notice deadlines?

Renewal options, expansion rights and termination rights usually require written notice by a hard date. Miss it and the right is often gone. Some leases also renew automatically unless you give notice to leave. Choosing the right lease term length up front makes these dates easier to plan around. Short terms make this even more important: in Q3 2026, 46.4% of office searches on TenantBase sought lease terms under one year, according to the TenantBase Q3 2026 Tenant Demand Report.

How to negotiate it

  • Require the landlord to send a reminder before the deadline, with a grace period after it
  • Make any renewal your option, never automatic
  • Put every notice date on your calendar the day you sign
  • Start market research 12 to 18 months before expiration so you know what your option is worth

7. Uncapped escalations

Rent that grows in the dark

A dental office signs a lease with rent increases tied to inflation and no ceiling. Inflation spikes, and so does the rent.

What is a rent escalation clause?

Escalation clauses raise rent during the term, either by a fixed percentage, a fixed dollar amount, or an index such as the Consumer Price Index. In gross and modified gross leases, separate pass-throughs can raise your share of operating expenses above a base year.

How to negotiate it

  • Fixed annual increases you can budget for, rather than an uncapped index
  • If rent is tied to an index, a ceiling on each annual increase
  • A cap on controllable operating expense increases, as in clause 1
  • A base year that reflects a normal, fully occupied building

8. Missing exclusive use

The competitor next door

A coffee shop opens in a busy strip center. A year later, the landlord leases the end cap to a national coffee chain.

What is an exclusive use clause?

An exclusive use clause stops the landlord from leasing to tenants who compete with your core business. Without one, nothing does. If the landlord breaches it, remedies can include terminating the lease and recovering damages, or staying and reducing the rent by an agreed amount, according to Lowndes.

How to negotiate it

  • Ask for it in the letter of intent, not at the lease stage
  • Describe your primary products or services clearly, not too narrow and not too broad
  • Set the remedy in writing: reduced rent until the violation ends, and a right to terminate if it continues
  • Ask for a radius covering the landlord's nearby centers

Frequently asked questions

What should I look for before signing a commercial lease?
Start with eight clauses: CAM reconciliation, personal guarantee, relocation, holdover, restoration, notice deadlines, escalations and exclusive use. Then have a tenant rep broker and a real estate attorney review the full lease.
What is a CAM reconciliation?
A year-end comparison of the CAM estimates you paid against the landlord's actual costs. If costs ran higher, you owe the difference. Most landlords send them in the second quarter.
Can I avoid a personal guarantee on a commercial lease?
Sometimes. Established businesses can often negotiate it away or replace it with a larger deposit. Newer businesses can usually limit it with a good guy clause, a dollar cap or a burn-off date.
What is holdover rent?
The rent you owe if you stay past your lease expiration without a new agreement. It is often 150% to 200% of your final rent.
What is a good guy guarantee?
A guarantee that ends your personal liability once you give the required advance notice, often 90 to 180 days, vacate properly and are current on rent through your move-out date.
Can a landlord make me move to a different suite?
Only if your lease has a relocation clause. Negotiate it out, or define comparable space and make the landlord pay all costs.
Does a tenant rep broker cost money?
Not when you use TenantBase. Matching is free for tenants, and the landlord typically pays the broker's commission when the lease is signed.
