Commercial Lease Negotiation Tips for Small Businesses
What small business owners should know before signing a commercial lease: lease types, the clauses that cost money, landlord questions and a negotiation checklist.
To negotiate a commercial lease well, a small business needs to know which lease type it is being offered, what the rent really costs once extra charges are added, and which clauses to push back on before signing. This guide explains gross vs. triple net (NNN) leases, the 12 clauses that matter most, the questions to ask a landlord, and a negotiation checklist you can print and bring to the table.
Key Takeaways
- Compare spaces on total occupancy cost (base rent plus taxes, insurance, maintenance and CAM), not the headline rent per square foot.
- In a triple net lease, the tenant pays a share of property taxes, building insurance and common-area maintenance on top of base rent. Ask for a cap on controllable CAM increases.
- Your biggest levers are usually term length, renewal options, free rent, tenant improvement allowance and the personal guarantee.
- Under the ADA, landlord and tenant both remain responsible to the public, even if the lease splits the work between them.
- Commercial leases get far less legal protection than home leases. Have a commercial real estate attorney review the draft before you sign.

Why commercial leases need more care than apartment leases
Residential tenants in the US benefit from a lot of consumer-protection law: limits on deposits, required disclosures, habitability rules. Commercial tenants mostly do not. The law treats a business and a landlord as two parties able to negotiate, so the written lease is almost the whole deal. Whatever the lease says about repairs, rent increases or leaving early is generally what you will live with.
That cuts both ways. Very little is standard, so nearly everything is negotiable, especially for a small tenant in a market with vacancies. The landlord’s first draft is written to protect the landlord. Treat it as an opening offer.
Location choice comes first, of course. The SBA’s guide to picking a business location covers zoning, foot traffic and other checks to do before you get to lease terms.
Commercial lease types explained: gross, modified gross and NNN
The lease type decides who pays the building’s running costs. Two spaces with the same rent per square foot can differ by thousands of dollars a year depending on this one feature.
| Lease type | Tenant pays | Landlord pays | Common in | Watch out for |
|---|---|---|---|---|
| Full-service gross | One rent amount | Taxes, insurance, maintenance, often utilities and janitorial | Multi-tenant office buildings | “Base year” clauses that pass on cost increases after year one |
| Modified gross | Rent plus some costs (often utilities, in-suite repairs) | Remaining building costs | Small office, flex space | Vague wording on who pays what |
| Single net (N) | Rent plus property taxes | Insurance and maintenance | Less common | Tax reassessments after a sale |
| Double net (NN) | Rent plus taxes and building insurance | Maintenance and repairs | Some retail and office | Insurance premium spikes |
| Triple net (NNN) | Rent plus taxes, insurance and common-area maintenance (CAM) | Often only structural items such as roof and foundation, depending on the lease | Retail centers, standalone buildings, industrial | Uncapped CAM, roof and HVAC replacement costs |
| Percentage lease | Base rent plus a percentage of sales above a set level | Varies | Malls and larger retail centers | How “gross sales” is defined |
Exact definitions vary by market and by landlord. A “net” lease in one city may mean something slightly different in another, so always read the expense clause itself rather than relying on the label.
Worked example: comparing two offers
For example, an illustrative boutique fitness studio is choosing between two 1,500 sq ft spaces.
- Space A (gross): $30 per sq ft per year, all building costs included. Annual cost: 1,500 x $30 = $45,000.
- Space B (NNN): $22 per sq ft base rent plus estimated NNN charges of $9 per sq ft. Annual cost: 1,500 x ($22 + $9) = $46,500.
Space B looks cheaper by $8 a foot but costs $1,500 more in year one, and the NNN portion can rise every year. Ask the landlord for the last two to three years of actual NNN or CAM charges, not just this year’s estimate. Then build the full occupancy cost into your budget and check what it does to your margins; a quick run through a profit margin calculator shows whether the location still works at your expected sales.
12 lease clauses that matter most (and what to ask for)
1. Term and renewal options
Landlords like long terms; new businesses need flexibility. A common middle ground is a shorter initial term with one or more renewal options at your choice, for example three years plus two three-year options. Get renewal rent defined now (a fixed increase or a capped market rate), not “to be negotiated.”
2. Rent escalations
Most leases raise rent each year, either by a fixed percentage or tied to an inflation index. Know which, and ask for a cap if it is index-based.
3. CAM and operating expenses
Ask exactly what is included, how your share is calculated (usually your square footage divided by the leasable area), whether there is a cap on increases in controllable expenses, and whether you have the right to audit the landlord’s annual reconciliation. Push to exclude capital improvements, the landlord’s management overhead beyond a set percentage, and costs of leasing other spaces.
4. Free rent and rent commencement
You may be paying rent while contractors are still building out your space. Negotiate a rent-free period, and tie rent commencement to the later of a fixed date or when you can legally open (for example, after your certificate of occupancy).
5. Tenant improvement (TI) allowance
This is money the landlord contributes to build out your space. Ask for it in dollars per square foot, find out whether it is paid upfront or reimbursed, and confirm who owns the improvements at the end.
6. Permitted use and exclusivity
A narrow use clause (“sale of coffee”) can block you from adding food later. Ask for a broad use. In a retail center, ask for an exclusive so the landlord cannot lease next door to a direct competitor.
7. Assignment and subletting
If you sell the business or need to downsize, you will want to assign or sublet. Ask that landlord consent “not be unreasonably withheld” and that a sale of your business is allowed.
8. Personal guarantee
Small tenants are almost always asked to personally guarantee the lease. Negotiate its size: cap it at a set number of months of rent, have it burn off after a period of on-time payments, or ask for a “good guy” guarantee that ends your personal liability if you give proper notice, pay rent through move-out and hand back the keys.
9. Repairs and maintenance
Spell out who repairs and who replaces the roof, structure, HVAC, plumbing and electrical systems. An older rooftop HVAC unit can be expensive to replace. If you must maintain it, ask the landlord to certify it is in good working order at handover and to cover replacement.
10. ADA and code compliance
Accessibility work can be a surprise cost. The Justice Department’s ADA Title III Technical Assistance Manual says both the landlord and the tenant are public accommodations with full responsibility. The lease can divide the work between you, but that split only applies between the two of you; both remain liable to customers. Ask the landlord to deliver the space code-compliant, and get any existing issues fixed before you move in.
11. Signage
For retail, visibility is part of the value. Get your sign rights (size, placement, pylon or monument sign) written into the lease, subject to local permits.
12. Early termination and relocation
Ask for a one-time early termination right with a set fee. Watch for a relocation clause that lets the landlord move you to another unit; if you accept one, require a comparable space and that the landlord pays all moving and build-out costs.
Questions to ask the landlord before you negotiate
- What were the actual CAM or NNN charges per square foot for the last three years?
- Is the measured square footage usable or rentable, and what load factor is applied?
- Why did the last tenant leave, and how long has the space been vacant?
- What age and condition are the HVAC, roof and electrical service?
- Are any big capital projects planned, such as a parking lot repave or roof replacement?
- Is the property being marketed for sale, or is the mortgage being refinanced?
- Does zoning allow my use, and will the landlord help with permits?
- What signage is allowed on the building and on any shared sign?
- Will the landlord provide a subordination, non-disturbance and attornment agreement (SNDA) so a lender cannot end my lease if the landlord defaults?
- What tenant improvement allowance and free rent are other recent tenants getting?
How to negotiate: a step-by-step approach
- Work with a tenant-side broker. In many markets the landlord pays the broker’s commission. A tenant rep knows what concessions are typical locally.
- Tour three or more spaces. Real alternatives give you bargaining power, and landlords know when you have none.
- Ask for a letter of intent (LOI) first. Agree the business points (rent, term, TI, free rent, options) in a short non-binding LOI before lawyers draft the lease.
- Prioritize. Decide your three must-haves and what you can give up. Landlords often trade more free rent for a longer term, for example.
- Read the full lease, not the summary. Many costly items live in the definitions section and the exhibits.
- Get an attorney review. A few hours of legal review is small next to a five-year commitment.
- Get every promise in writing. “We’ll fix that before you move in” means nothing unless it is in the lease or a signed work letter.

After you sign: setting up the new location
Once the lease is signed, put the key dates in your calendar: rent commencement, the renewal option deadline (often six to twelve months before the term ends), escalation dates and the annual CAM reconciliation. Missing a renewal notice deadline can cost you your option.
When you are ready to open, a grand opening is one of the few times a small business has genuine local news. If you plan to tell local media, our guide on how to write a press release walks through the format, and the headline guide helps you lead with what is new for the neighborhood.
Frequently Asked Questions
What does NNN mean in a commercial lease?
NNN stands for triple net. The tenant pays base rent plus a share of the property’s taxes, building insurance and common-area maintenance. The landlord typically keeps responsibility for some structural items, but this varies, so check the lease.
Is a gross lease or a NNN lease better for a small business?
A gross lease gives predictable costs, which helps new businesses budget. A NNN lease often has lower base rent but costs that can rise. Compare the total occupancy cost over the whole term, not the rent alone.
Can I negotiate a commercial lease as a brand-new business?
Yes, though you may have less bargaining power and be asked for a larger deposit or personal guarantee. A solid business plan, financial statements and a few competing options strengthen your position.
What is a reasonable length for a first commercial lease?
Many small businesses aim for three to five years with renewal options. A longer term may earn more free rent or TI money, but it raises your risk if the business does not work out at that site.
What is a “good guy” guarantee?
It limits a personal guarantee so that, if you give proper notice, pay rent until you leave and return the space in agreed condition, your personal liability ends. It is common in some markets, such as New York City office leases, and less common elsewhere.
Do I really need a lawyer to review a commercial lease?
It is strongly recommended. The lease may commit you to hundreds of thousands of dollars over its term, and commercial tenants get few legal protections beyond what the lease says. Rules also vary by state.
Your next step
Before your next landlord meeting, collect the last three years of CAM figures, calculate total occupancy cost for each space you are considering, and choose your three non-negotiables. Bring the checklist above, agree the big points in a letter of intent, and hand the draft lease to a commercial real estate attorney before you sign anything. The time you spend now is cheaper than five years of a bad clause.
