A commercial lease is not a residential lease with bigger numbers. It is a long-term business contract, negotiated between sophisticated parties, and courts generally enforce it exactly as written. That means the leverage you have is almost entirely at the front end — before you sign. This guide walks through the clauses that most often become disputes and what to negotiate before the ink dries.
Understand the Real Rent Structure
The base rent number is only part of the picture. Most commercial leases pass additional costs through to the tenant under labels like 'triple net,' 'CAM,' 'operating expenses,' or 'tax and insurance escalations.'
Before signing, ask for a written breakdown of the last two years of pass-through charges. A base rent that looks competitive can become expensive once operating costs, property taxes, and management fees are layered on. In multi-tenant buildings, insist on a cap on controllable expenses and the right to audit the landlord's calculations.
Watch the Term, Renewal, and Escalation Clauses
The length of the term should match your business plan. A five-year lease with two five-year renewal options gives you flexibility; a straight ten-year term locks you in.
Pay attention to how rent escalates. Fixed annual increases are predictable. CPI-based escalations can spike in high-inflation years. 'Fair market' resets at renewal are the most dangerous — they can effectively price you out of the space you built out. If a fair-market reset is unavoidable, negotiate a floor and a ceiling so the number cannot swing wildly against you.
Assignment, Subletting, and Business Sales
If you may sell your business, bring in a partner, or restructure your entity during the term, the assignment clause becomes critical. Overly restrictive language can block a sale of the business or trigger a landlord's right to recapture the space.
Common negotiation points include:
- A clear right to assign to an affiliate or successor by merger
- Reasonable, defined standards for landlord consent
- Continued personal guarantee limits after an approved assignment
- Sublease rights, especially for excess space
- Recapture rights that do not fire on ordinary corporate reorganizations
Personal Guarantees
Many landlords ask for a personal guarantee from the tenant's owners. This is negotiable more often than tenants realize.
Look for a 'good guy' guarantee, capped guarantees, or a burn-off provision that reduces or ends the guarantee after a period of on-time performance. The goal is to limit personal exposure without derailing the deal. In a good deal, the guarantee covers behavior — like surrendering the space in good condition — rather than the entire rent stream.
Build-Out, Delivery Condition, and Repairs
Who is building what — and paying for it — should be spelled out in detail. Vague 'landlord to deliver in vanilla box condition' language is a frequent source of dispute.
Clarify tenant improvement allowances, timelines, permitting responsibility, and what happens if delivery is delayed. On repairs, understand your obligations for HVAC, roof, structural components, and common areas. These allocations drive your true cost of occupancy. A single 'tenant maintains HVAC' clause can turn into tens of thousands of dollars over a long term.
Default, Cure, and Remedies
Not all defaults are equal. A missed insurance certificate should not carry the same consequences as unpaid rent. Reasonable notice-and-cure periods protect tenants from accidental defaults that escalate into termination or acceleration of rent.
Look carefully at the landlord's remedies, including any acceleration of future rent, lien rights on personal property, and self-help provisions. Insist on notice to any lender or guarantor before the landlord can declare a default, and make sure cure periods are long enough to actually cure.
Insurance, Indemnity, and Casualty
Insurance and indemnity clauses often get skimmed and later become expensive. Read the required coverage amounts, the additional-insured requirements, and the waiver-of-subrogation language. Confirm your policy can actually meet the lease's requirements before signing.
In casualty and condemnation clauses, look for termination rights when significant portions of the premises are unusable and for reasonable rent abatement while repairs are underway.
When to Bring in an Attorney
Engage counsel before signing a letter of intent, not after the lease is drafted. The letter of intent shapes the lease, and most 'non-binding' business points get carried straight into the final document.
Attorney involvement is particularly important for long terms, large build-outs, personal guarantees, medical or food-service uses, and any deal where you plan to invest heavily in the space.
