Commercial Lease Guide: Clauses That Cost You Money Before You Sign

This commercial lease guide walks you through every clause that can cost you money, in the order you will meet them as you read the document. You will see the exact wording to watch for, why it matters to your cash flow, and the specific counter-ask to take to the landlord. Lease rules vary by state, so use this as a list of what to ask for, and check local rules on anything high-stakes.

Key takeaways

• Check the commencement date and rent-free fit-out start before you sign.
• Cap rent reviews and outgoings so costs stay predictable.
• Limit repair obligations to non-structural items and document the condition at move-in.
• Cap or time-limit any personal guarantee before you agree to it.
• Make break clauses depend only on rent payment and proper notice.

Rent, term, and the first payment schedule

What should I check in the commencement date?

Look for a commencement date tied to "landlord's substantial completion" or "delivery of possession" without a hard outside date. That lets the landlord delay handover while your rent clock ticks or your fit-out period shrinks.

Ask for a fixed commencement date or a long-stop date after which you can walk away without penalty. If the lease includes a rent-free fit-out period, confirm it starts on the day you get keys, not on the lease execution date. An example clause: "Rent commences on the earlier of (a) the date Tenant opens for business or (b) 90 days after Landlord delivers possession." Ask to delete (a) and keep only the outside date.

Imagine you sign a lease in January with a promised March handover. The landlord runs behind and does not hand over keys until June, but your rent clock started on April 1. You pay for three months of space you cannot use while your fit-out window vanishes.

Rent review mechanisms that drive future cost

How do rent reviews work in a commercial lease?

Many leases longer than a year include a rent review clause, so look for one early in the lease. The three common types are fixed percentage increases, CPI-linked increases, and market reviews. A fixed annual increase, for example 3 percent, is predictable. A CPI clause should state which index, the base month, and a cap and floor. A market review often says "rent shall be the fair market rent as determined by an independent valuer" and may add "upward only." Upward-only means rent never drops even if the market falls.

Ask for a cap on market reviews (for example 10 percent over the prior year) and a collar that lets rent move down as well as up. If the landlord insists on upward-only, negotiate a lower starting rent to offset the one-way risk.

Picture a cafe on a five-year lease. The market dips in year three, but an upward-only review keeps rent at the year-two peak. The owner pays above-market rent for the rest of the term with no way to bring it down.

Outgoings, CAM charges, and operating expenses

What are CAM charges in a commercial lease?

Beyond base rent you will pay a share of the building's operating costs. The lease may call these "Additional Rent," "CAM Charges," or "Operating Expenses." Watch for language that lets the landlord include capital expenditures, management fees above a market rate, or costs for other tenants' exclusive use areas. A typical line: "Tenant shall pay its proportionate share of all costs, expenses, and charges of every kind incurred by Landlord in operating, maintaining, repairing, and managing the Property."

Ask for an itemized annual budget, a right to audit the landlord's books, and a cap on controllable expense increases (for example 5 percent year over year). Exclude capital replacements, leasing commissions, and legal fees for other tenants' disputes.

As an illustration, imagine a boutique that budgets $1,000 a month for CAM charges. Mid-year the landlord bills an extra $4,000 for a new roof and parking-lot paving. Those capital costs hit the tenant's books with no cap and no prior notice.

Repair, maintenance, and make-good obligations

What does make-good mean in a commercial lease?

The repair clause defines what you must fix and what condition you must return the premises in. A landlord-friendly version: "Tenant shall keep the Premises in good repair and condition, structural and non-structural, and shall yield up the Premises at the end of the Term in the same condition as at the commencement date, fair wear and tear excepted." That can force you to replace an aging roof or HVAC system.

Ask to limit your obligation to non-structural elements and to the condition documented in a schedule of condition with dated photos at move-in. Ask to add "fair wear and tear excepted" and exclude latent defects and end-of-life building systems.

Picture a clinic that takes over a suite with a 15-year-old HVAC unit. The system fails in year two. Under a broad repair clause, the clinic pays for a full replacement even though the equipment was near the end of its life on day one.

Assignment and subletting: keep your exit options

Can I assign or sublet my commercial lease?

Most leases let you assign or sublet only with "Landlord's consent, not to be unreasonably withheld." The trap is in the conditions that follow: you must be in full compliance with every covenant, the assignee must meet net-worth tests, and you remain liable for the full remaining term. A clause may read: "Landlord may condition consent on Assignee assuming all obligations and Tenant remaining jointly and severally liable."

Ask for a carve-out that lets you assign to an affiliate or a buyer of your business without a net-worth test. Push for a release of your liability after a reasonable period (for example 12 months) if the assignee performs. Ask to remove "full compliance with all covenants" as a condition for consent.

Imagine an agency owner who wants to sell the business after three years. The buyer is solid, but the landlord denies consent because the tenant missed one CAM payment two years earlier. The sale stalls, and the original tenant remains on the hook for seven more years of rent.

Break clause conditions that can trap you

How does a break clause work in a commercial lease?

A break clause lets you end the lease early on a fixed date. The clause often says: "Tenant may terminate on the Break Date by giving not less than six months' written notice, provided that all rents and additional rent have been paid and Tenant has complied with all covenants." If you missed a single CAM payment or a minor repair, the break fails.

Ask for a break condition limited to payment of rent and additional rent actually due, not "all covenants." Require the landlord to give a written statement of amounts due at least 30 days before the notice deadline so you can clear them. Keep the notice period to six months or less.

Picture a retailer that exercises its break clause on time. The landlord rejects the notice because a $200 CAM invoice from eight months ago went unpaid. The break fails, and the retailer is locked in for another three years.

Personal guarantee: cap, limit, or trade it

Should I sign a personal guarantee for a business lease?

If your business is an LLC or corporation, the landlord will often ask for a personal guarantee. An unlimited guarantee reads: "Guarantor unconditionally guarantees the full and prompt payment of all Rent, Additional Rent, and all other obligations of Tenant under the Lease, without limitation of amount or time." That puts your house and personal savings on the line for a ten-year lease.

Never sign an unlimited guarantee. Ask for a cap (for example 6 to 12 months of base rent), a sunset date (for example, the guarantee ends after year three if there has been no default), or a larger security deposit in exchange for no guarantee. If the rent is high or the term is five years or more, have a lawyer review the guarantee before you sign.

Imagine a founder who signs a five-year lease with an unlimited personal guarantee. The business closes in year two. The landlord pursues the founder's personal savings and home for the remaining three years of rent and CAM charges.

Lock-in clauses: auto-renewal, holdover, and early termination penalties

What are lock-in clauses in a commercial lease?

A lease may auto-renew for another term unless you give notice by a deadline, sometimes 180 days or more before the term ends. A holdover clause may charge a multiple of rent, for example 150 percent or 200 percent, if you stay one day past the term. An early termination penalty may demand the full remaining rent accelerated to present value. These are lock-in clauses that remove your leverage.

Ask for renewal to need your written confirmation, or at least a written reminder from the landlord well before the notice deadline. Ask for a cap on holdover rent, for example 125 percent of base rent. Ask to replace accelerated rent penalties with a fixed early-termination fee (for example three months' rent) that declines over time.

As an illustration, picture a shop owner with a 180-day notice deadline who misses it by one week. The lease rolls for another five years. The owner wants to relocate but cannot exit without paying years of future rent.

Insurance, indemnity, and casualty

The lease will require you to carry general liability, property, and often business interruption insurance. The indemnity clause may say: "Tenant shall indemnify Landlord from any and all claims arising out of Tenant's use or occupancy of the Premises." That can cover the landlord's own negligence.

Ask for a mutual indemnity limited to claims caused by your own negligence or breach. Confirm with your insurer how building cover works under the lease, and ask that the landlord's insurer cannot pursue you for damage the landlord's own policy covers (a waiver of subrogation). Insurance and subrogation rules vary by state and by policy, so confirm the wording with your insurer. On casualty, ask for the right to terminate if the premises cannot be restored within 90 to 120 days.

Default, cure periods, and landlord remedies

A default clause often lists "failure to pay rent when due" as an immediate default with no cure period. For non-monetary defaults, a short cure period, for example 10 days, may not leave time for permits or contractor scheduling. Landlord remedies may include "re-entry and re-letting at Tenant's expense" with you liable for the shortfall.

Ask for a grace period on rent (for example 5 business days) and a longer cure period for non-monetary defaults (for example 30 days), with an extension if you are diligently pursuing the cure. Ask to limit the landlord's re-letting costs to actual, reasonable expenses.

Governing law, venue, and attorney fees

If the landlord is based in another state, the lease will pick their state's law and their local court. A clause may read: "This Lease shall be governed by the laws of the state where Landlord is located. Any action shall be brought exclusively in the courts of the county where Landlord is located." Litigating across the country can cost more than the dispute is worth.

Ask for your home state's law or a neutral venue. If the landlord refuses, ask for a mandatory mediation step before litigation and a fee-shifting provision that awards fees to the prevailing party, not just the landlord. Ask a local attorney how your state treats venue and fee clauses.
