Commercial lease
IN PLAIN ENGLISH

Common clauses in a commercial lease

• Premises and permitted use

  Defines exactly what space you're leasing — the square footage, suite number, common areas you can access, and parking — and what you're allowed to do there. The use clause matters: if you sign a lease for "general office use" and later want to add a retail component or food service, you may need landlord approval or a lease amendment. Some use clauses are exclusive, preventing the landlord from leasing to a competing business in the same building.

• Lease term and renewal options

  The start date, end date, and any options to extend. Renewal options typically must be exercised in writing within a notice window (often 6-12 months before the term ends) and may specify the renewal rent in advance or tie it to fair market value or a fixed escalation. If you fail to exercise on time, you lose the option.

• Base rent and escalations

  The starting rent (usually quoted per square foot per year) and how it increases over time. Escalations can be fixed (e.g., 3% per year), tied to CPI (consumer price index), or adjusted to "fair market value" at specified intervals. Predictable escalations are better for planning; FMV resets expose you to bigger jumps if the market rises.

• Operating expenses and CAM charges

  In a net lease, the tenant pays a share of the building's operating expenses — property taxes, insurance, maintenance, and common area costs (CAM). The lease should specify what's included, how your share is calculated (usually pro-rata by square footage), whether there's a cap or base-year stop, and when you get an annual reconciliation. Uncapped operating expenses can turn a seemingly affordable rent into a budget-breaker.

• Security deposit and guarantees

  Commercial leases often require several months' rent as a security deposit, plus a personal guarantee from the business owner if the tenant is a newly formed LLC or corporation. A personal guarantee makes you personally liable for the lease obligations if the business can't pay — essentially putting your personal assets on the line. Negotiating a limited or "burn-off" guarantee (one that expires after a few years of timely payment) is critical if you can get it.

• Build-out and tenant improvements

  Who pays for the initial construction or customization of the space — walls, flooring, HVAC, fixtures — and who owns it at the end of the lease. Landlords often contribute a tenant improvement allowance (TIA), expressed as dollars per square foot, toward build-out costs. The lease should clarify the approval process, the timeline, and whether you can take any improvements with you or must restore the space to its original condition.

• Maintenance and repairs

  Allocates responsibility for keeping the space in working order. In a gross lease, the landlord typically handles most repairs; in a triple-net lease, the tenant is responsible for everything inside the premises and sometimes the roof and structure. Who fixes the HVAC, plumbing, electrical, and exterior — and how fast — should be explicit.

• Assignment and subletting

  Whether you can transfer your lease to another business (assignment) or rent out part of your space (subletting) without landlord consent. Most commercial leases prohibit assignment and subletting without approval, which the landlord may withhold at its discretion. If you might need flexibility — to downsize, merge, or sell the business — negotiate for a right to assign with reasonable approval standards.

• Default and remedies

  Defines what counts as a default (non-payment, breach of covenants, bankruptcy), what notice and cure periods you get, and what the landlord can do if you don't fix the problem. Landlord remedies typically include eviction, acceleration of rent (making the full remaining lease balance due immediately), and recovery of re-letting costs. The more tenant-friendly the default clause, the more time and protection you have if things go wrong.

• Early termination and break clause

  Whether you can end the lease before the term is up, and at what cost. True termination rights are rare in commercial leases; when they exist, they usually require significant notice (6-12 months) and payment of a termination fee (often several months' rent). If business conditions are uncertain, negotiating a break clause can be worth more than a lower rent.

• Holdover

  What happens if you stay past the end of the lease without renewing. Commercial holdover clauses are often punitive — rent may jump to 150-200% of the prior rate, and the landlord may have the right to evict immediately. Know the deadline to renew or vacate.

• Insurance

  Requires the tenant to carry commercial general liability, property insurance, business interruption insurance, and sometimes umbrella coverage, with specified minimums. The landlord will want to be named as an additional insured and may require a waiver of subrogation (preventing your insurer from suing the landlord). Review with your broker before signing.

• Relocation clause

  A provision that lets the landlord move you to a different space in the building, usually with notice and at landlord's expense. This is common in larger office buildings and protects the landlord's ability to consolidate floors for bigger tenants. If your location matters (retail frontage, for example), negotiate limits or remove this clause.

• Co-tenancy and exclusivity

  Retail leases may include co-tenancy clauses — the right to pay reduced rent or terminate if anchor tenants leave the shopping center — and exclusivity clauses — a promise that the landlord won't lease to a competing business. These are valuable protections but often heavily negotiated.

Red flags to watch for

• Unlimited personal guarantee

  A guarantee with no cap and no expiration that makes you personally liable for the entire lease term (potentially 5-10 years of rent). Push for a cap (e.g., 12 months' rent) and a burn-off (guarantee ends after 2-3 years of timely payment).

• Uncapped operating expenses

  A net lease with no limit on how much operating expenses can increase year over year. Without a cap or base-year stop, your costs can rise faster than your revenue. Ask for a cap (e.g., 5% annual increase) or gross-up protections.

• Aggressive default and acceleration provisions

  A clause that declares a default after a single missed payment with no cure period, and accelerates the entire remaining rent immediately. Standard terms give you at least 5-10 days' written notice before a monetary default and 30 days for non-monetary breaches.

• One-sided assignment rights

  The landlord can sell the building or assign the lease freely, but you can't assign or sublet without approval that may be withheld for any reason. Ask for "reasonable consent not to be unreasonably withheld."

• Demolition or redevelopment clause

  A right for the landlord to terminate your lease with limited notice if they decide to demolish or redevelop the building. This is a real risk in areas with rising property values. Negotiate for longer notice, relocation assistance, or lease buyout compensation.

• Broad "continuous operation" requirement

  A clause that requires you to remain open for business at specified hours throughout the lease term, even if the business is failing. Violating this can trigger a default. Retail tenants should push back on overly rigid operating requirements.

• No exclusivity or weak co-tenancy

  A retail lease that doesn't prevent the landlord from putting a direct competitor next door, or that lacks co-tenancy protections if anchor tenants leave. If foot traffic matters to your business, these clauses matter.

• Restoration obligations

  A requirement to return the space to its "original condition" at the end of the lease, which could mean tearing out expensive build-out you paid for. Negotiate for landlord waiver of restoration or the right to leave improvements in place.

Frequently asked questions

• Am I personally liable if my business can't pay the rent?

  Only if you signed a personal guarantee — and many commercial leases for new LLCs or corporations require one. A personal guarantee means the landlord can come after your personal assets (savings, home) if the business defaults, even though the LLC was supposed to shield you. Try to negotiate a cap (e.g., limited to 12 months' rent) or a "burn-off" that ends the guarantee after a few years of on-time payments. This is general information, not legal advice.

• What does triple-net (NNN) actually mean for what I'll pay?

  In a triple-net lease, on top of base rent you also pay your pro-rata share of property taxes, insurance, and maintenance/common-area (CAM) costs — so your real monthly cost is meaningfully higher than the quoted rent. These pass-throughs can rise year over year, sometimes sharply, unless the lease caps them, so always ask for your estimated total annual cost, not just the base rent.

• Can the landlord kick me out before my lease is up?

  Not without grounds. Outside of your defaulting (usually non-payment or breach), the landlord generally can't terminate early unless the lease contains a specific clause letting them — most commonly a demolition or redevelopment clause. If your lease has one of those, you can be forced out on limited notice, so it's worth negotiating for longer notice or a buyout. Laws and lease terms vary.

• Is my commercial lease negotiable, or do I just sign what they give me?

  Almost everything in a commercial lease is negotiable — rent escalations, the personal guarantee, operating-expense caps, build-out allowances, assignment rights, and exit options. Unlike residential tenants, commercial tenants don't have much statutory protection, so the lease itself is your only protection. Your leverage is highest before you sign and disappears the moment you do.

• What happens to my lease if I want to sell my business?

  That depends on the assignment and subletting clause. Most commercial leases prohibit you from transferring the lease without the landlord's consent, and the landlord may be allowed to withhold consent for any reason. If you might sell, merge, or downsize later, negotiate up front for the right to assign with the landlord's "consent not to be unreasonably withheld." This is general information; have a lawyer review the specific language.
