Why Commercial Leases Are Different
Residential leases protect tenants with an entire body of consumer protection law: habitability requirements, security deposit caps, and statutory notice periods. Commercial leases have none of that. The law assumes you're a sophisticated business entity bargaining at arm's length — even if you're a first-time entrepreneur signing a 5-year lease you barely understand.
A commercial lease is typically a 3-to-10-year commitment, and the total cost — rent, CAM, utilities, insurance, property tax share — often exceeds your annual payroll for a small business. Yet most business owners spend more time comparing office chairs than reviewing their lease. A mistake in the rent escalation clause alone can cost more than every piece of furniture in the office.
Here are the 10 clauses that determine whether your lease works for your business — or against it.
1. Rent Structure — Beyond the Square Foot
Commercial rent isn't just one number. It's a stack of charges that the landlord can increase over time. The base rent is the starting point, but that $25/sqft number in the listing might actually mean $25 base + $12 CAM + $5 tax share + $3 insurance = $45/sqft. Ask for the all-in cost — not just the base rent.
Rent escalation is the bigger risk. Most commercial leases include annual increases: fixed (3% per year every year), CPI-indexed (tied to inflation), or market-reset (adjusted to 'fair market rent' at renewal). Fixed increases are predictable but compound fast (3% per year over 5 years = 15.9% total increase, not 15% — it compounds). Market-reset at renewal gives the landlord maximum leverage: you're moved in, your customers know your location, and relocating is expensive.
Push for: fixed increases with a cap (e.g., 3% or CPI, whichever is lower), a clear all-in cost breakdown before signing, and an audit right — the ability to verify the landlord's CAM and tax calculations. If the landlord won't provide auditable numbers, assume they're inflated.
2. Lease Term and Renewal Options
The lease term — how long you're committed — determines your flexibility to grow, shrink, or pivot. A startup that signs a 10-year lease for space that fits 8 people is in trouble by year 3 when the team is 20. A retail business that signs a 3-year lease with no renewal option has built a customer base that belongs to the landlord at the end of the term.
Renewal options give you the right (not the obligation) to extend the lease on pre-agreed terms. Critical details: how many renewal terms (one 5-year renewal is standard; two 5-year renewals is better), how much notice you must give to renew (120-180 days is typical), and how the renewal rent is calculated (fixed increase is best; 'fair market rent' gives the landlord the upper hand).
Push for: at least one renewal option with a pre-set rent formula, and a right of first refusal on adjacent space — if the space next door opens up, you get first dibs. Business growth is unpredictable; your lease should accommodate it.
3. CAM Charges — The Hidden Rent
Common Area Maintenance (CAM) charges cover the landlord's costs for operating the building: parking lot maintenance, hallway cleaning, landscaping, security, management fees. In a single-tenant building, you probably pay these directly. In a multi-tenant building, the landlord allocates them among tenants — and this is where the abuse happens.
Red flags in CAM: (a) the landlord's 'administrative fee' of 10-15% on top of actual costs — you're paying the landlord a profit margin to manage their own building; (b) capital improvements included in CAM — a new roof benefits the landlord for 20 years, but you're paying for it in year 1 of a 5-year lease; (c) no audit right — you can't verify the numbers, so you pay what they say.
Push for: capital expenditures excluded from CAM (or amortized over their useful life, with your share limited to your lease term), the administrative fee capped at 3-5% or eliminated, CAM increases capped year-over-year (5-7%), and an audit right with the landlord paying the audit cost if CAM is overstated by more than 5%.
4. Repair and Maintenance Obligations
Who fixes what? In residential leases, the landlord fixes nearly everything. In commercial leases, the tenant often bears full responsibility for the interior — and sometimes for major building systems too. The key distinction is between a 'gross lease' (landlord handles most repairs, cost built into the rent) and a 'triple-net lease' (tenant pays rent + property taxes + insurance + maintenance — including roof, HVAC, and structural repairs).
In a triple-net lease, you could be on the hook for a $30,000 HVAC replacement in year 2. If the contract doesn't limit your maintenance obligations to 'ordinary wear and tear,' you could be responsible for structural repairs that benefit the landlord for decades after you leave.
Push for: the landlord responsible for roof, structure, foundation, and major building systems (HVAC, plumbing, electrical), your maintenance obligations limited to interior non-structural items, and a cap on your annual repair costs — or at least an exclusion for capital replacements.
5. Assignment and Subletting
Your business changes. You might outgrow the space, get acquired, or need to downsize. The assignment/subletting clause determines whether you can transfer the lease to someone else. Most commercial leases say you can't assign or sublet without the landlord's consent — and that consent 'shall not be unreasonably withheld.'
"Reasonably withheld" sounds fair, but courts interpret it differently. Some courts say the landlord can withhold consent for any commercially reasonable reason — including wanting higher rent than you're paying. Others require the landlord to have a very specific, objective reason. And in many states, the landlord can withhold consent for no reason at all unless the lease explicitly says otherwise.
Push for: the landlord's consent not to be unreasonably withheld, conditioned, or delayed, a list of specific circumstances where consent is not required (assignment to an affiliate, sale of your business, transfer to a subsidiary), and a time limit — if the landlord doesn't respond within 30 days, consent is deemed granted.
6. Permitted Use Clause
The permitted use clause says what kind of business you can operate in the space. It might read 'general office use' or 'retail sale of apparel and accessories.' Narrow use clauses are dangerous because your business can evolve. That 'general office use' might not cover a showroom or a training center if you pivot. That 'apparel retail' doesn't cover the cafe you want to add.
The landlord wants narrow use clauses: they control the tenant mix, comply with zoning, and prevent competing uses within their building. Your interest is flexibility: your business model might change, and reopening lease negotiations every time you pivot is expensive and slow.
Push for: the broadest use clause you can negotiate — 'general office use and any other lawful purpose' is ideal — plus the right to change your use with the landlord's consent, not to be unreasonably withheld. If the landlord insists on narrow use for zoning or lender reasons, at least list specific alternative uses that are pre-approved.
7. Exclusivity (for Retail Tenants)
If you're a retail tenant, an exclusivity clause prevents the landlord from leasing space to your direct competitors. A coffee shop should negotiate that no other coffee shop can operate in the same shopping center. A gym should ensure no other fitness center moves in next door. Without exclusivity, you could spend years building a customer base, only to have the landlord lease the unit next door to a competitor with twice your marketing budget.
The key is specificity: 'coffee shop' is too broad if the landlord's lawyer says a bakery that sells espresso isn't a coffee shop. Define the exclusivity by reference to what you actually sell: 'the sale of espresso-based beverages as a primary business (more than 30% of revenue).' Also negotiate a remedy if the landlord violates exclusivity — rent abatement or lease termination are standard remedies, not just the right to complain.
Push for: exclusivity defined by your actual product/service category, with specific percentages and product descriptions, a list of existing tenants who are grandfathered in, and a meaningful remedy (rent reduction or termination right) if the landlord breaches.
8. Personal Guaranty
A personal guaranty means you, personally — not just your LLC or corporation — are on the hook for the lease if the business can't pay. This is standard for new businesses without a track record, but the scope can be minimized. The landlord's form will ask for an unconditional, continuing guaranty of the entire lease obligation. You want to negotiate that down.
Options to propose: (a) a 'good guy guaranty' — you guarantee rent only until you vacate the premises and return the keys (so the landlord can re-lease the space and you're not on the hook for the remaining term), (b) a guaranty that burns down over time — after 2-3 years of on-time payments, the guaranty expires entirely, or (c) a guaranty capped at a specific dollar amount (e.g., 6-12 months of rent).
Push for: a good guy guaranty as a starting position, with the guaranty burning down after 24-36 months of timely payment. The landlord's concern — that your new business might fail — is valid; their solution shouldn't be that you personally guarantee a 10-year obligation. Meet in the middle.
9. Default and Remedies
What happens if you're late on rent? Most commercial leases say: default after 3-5 days past the due date, landlord can terminate the lease, accelerate all remaining rent (you owe the entire remaining lease balance immediately), and evict you. That's a catastrophe scenario from being a week late on rent during a cash flow crunch.
Landlords want fast, harsh remedies because an empty commercial space takes months to re-lease. Your interest is realistic, proportional consequences. The default and remedies clause should reflect that you're a legitimate business, not a fly-by-night operation — things happen, and the landlord's remedy should be getting paid (with interest and fees), not destroying your business over a late payment.
Push for: a cure period of at least 10-15 days for monetary defaults (30+ days for non-monetary defaults), the landlord required to provide written notice before declaring default, the landlord's duty to mitigate damages by re-leasing the space (which reduces what you owe), and no acceleration of rent without giving you a chance to cure. A late fee of 5-10% is reasonable; acceleration is not.
10. Relocation and Demolition Clauses
A relocation clause allows the landlord to move your business to a different space in the same building or complex — at your expense. A demolition clause lets the landlord terminate your lease entirely if they decide to redevelop the property. Both clauses give the landlord flexibility at your cost, and they're often buried in the boilerplate.
Relocation is particularly dangerous for retail and restaurant tenants: your location is your business. Moving three doors down in the same shopping center could mean completely different foot traffic and visibility. If the landlord can relocate you at their discretion, you're bearing the risk of their development decisions.
Push for: strike the relocation clause if possible, or at minimum require that the new space is comparable in size, visibility, and foot traffic, the landlord pays all moving and buildout costs, and you receive a rent reduction during the transition. For demolition clauses: you should receive 6-12 months advance notice plus relocation reimbursement. If the landlord is getting a windfall from redevelopment, you shouldn't be the one paying for it.
