Restaurant Lease Negotiation: Triple Net, Percentage Rent, CAM Charges, and Tax Treatment

A restaurant operator who signs a lease without understanding the triple net structure, the CAM reconciliation, or the percentage rent clause will discover the true cost of occupancy only after the first annual reconciliation, when the landlord sends a bill for $15,000-$40,000 in additional charges that the operator did not budget for. The base rent is the number that appears in the listing. The actual occupancy cost includes base rent, property taxes (passed through), building insurance (passed through), common area maintenance (passed through), percentage rent (if gross sales exceed a breakpoint), and tenant improvement amortization. In a restaurant context, occupancy cost should run 6-10% of gross revenue. If it exceeds 10%, the location is either too expensive for the concept or the revenue is too low for the space.

What is a triple net lease and what does it actually cost?

A triple net (NNN) lease requires the tenant to pay three categories of expenses in addition to base rent: property taxes, building insurance, and common area maintenance (CAM). In a gross lease, the landlord absorbs these costs and builds them into the base rent. In a NNN lease, the landlord passes them through, and the tenant pays them as additional rent.

The three components:

Property taxes. The tenant’s share of the property tax assessed on the building (and sometimes the land). The share is typically proportional to the tenant’s leased square footage as a percentage of the total building. Property taxes can increase significantly during the lease term due to reassessment (especially after a sale of the property, which triggers reassessment in many jurisdictions) or due to increases in the local tax rate. A well-negotiated lease includes a property tax cap (limiting annual increases to a specified percentage) or a base-year provision (the tenant pays only increases above the property tax in the base year of the lease).

Building insurance. The tenant’s share of the landlord’s building insurance premium (not the tenant’s own liability or property insurance, which the tenant carries separately). This is typically the smallest of the three NNN components. The tenant should verify that the landlord’s insurance is reasonable and competitively priced, and that the lease allows the tenant to review the policy.

CAM charges. Common area maintenance includes: landscaping, parking lot maintenance and snow removal, exterior lighting, security, property management fees, trash removal (common areas), and sometimes structural repairs and capital expenditures. CAM is where the disputes happen. Landlords have been known to include capital expenditures (roof replacement, parking lot resurfacing, HVAC replacement) in CAM, which inflates the charge dramatically in the year of the expenditure. A well-negotiated lease includes a CAM cap (limiting annual increases to 3-5%), excludes capital expenditures from CAM (or amortizes them over their useful life), and gives the tenant audit rights (the right to review the landlord’s CAM calculations and supporting invoices).

Illustrative total occupancy cost: Base rent of $30/sq ft + property taxes of $5/sq ft + insurance of $1/sq ft + CAM of $6/sq ft = $42/sq ft total. For a 3,000 sq ft restaurant, the annual occupancy cost is $126,000, or $10,500/month, compared to a base rent of $90,000 ($7,500/month). The NNN charges add 40% to the base rent.

How does percentage rent work?

Percentage rent is a variable rent component based on the tenant’s gross sales. The landlord receives a percentage of gross sales above a “natural breakpoint” (or “artificial breakpoint,” depending on the lease structure).

Natural breakpoint. The natural breakpoint is the sales level at which the percentage rent equals the base rent. Formula: base rent divided by the percentage rate. If the base rent is $90,000 and the percentage rate is 6%, the natural breakpoint is $1,500,000. The tenant pays 6% of gross sales above $1,500,000 as additional rent. If gross sales are $2,000,000, the percentage rent is 6% x ($2,000,000 - $1,500,000) = $30,000.

Typical percentage rates for restaurants: 5-8% of gross sales, with 6% being the most common. Full-service restaurants are typically at the lower end (5-6%) because food cost and labor are higher. Quick-service restaurants are at the higher end (6-8%) because operating margins are higher.

Gross sales definition. The definition of “gross sales” in the lease is critical. The tenant should negotiate exclusions for: sales tax collected, tips and gratuities, employee meals, promotional discounts and coupons, gift card sales (until redeemed), insurance proceeds, and off-premises catering (if performed away from the leased premises). Without these exclusions, the tenant pays percentage rent on items that are not revenue (sales tax) or that have already been discounted (promotional sales).

Reporting and audit. The lease typically requires the tenant to report gross sales monthly or quarterly and to provide an annual certified sales report (sometimes audited). The landlord has the right to audit the tenant’s sales records. The POS system must be configured to track the gross sales definition consistently with the lease.

What are tenant improvement allowances and how are they taxed?

A tenant improvement (TI) allowance is a contribution from the landlord toward the tenant’s buildout costs. The landlord provides a dollar amount per square foot (or a lump sum), and the tenant uses it to construct the restaurant interior (kitchen, dining room, bar, restrooms, HVAC, plumbing, electrical).

Typical TI allowance for restaurants: $30-$100/sq ft, depending on the market, the landlord’s investment thesis, and the tenant’s credit. Restaurant buildouts are expensive ($150-$400/sq ft for a full-service restaurant), so the TI allowance covers only a portion of the total cost.

Tax treatment under IRC 110. A qualified lessee construction allowance is excluded from the tenant’s taxable income if: (1) the allowance is used to construct or improve real property (not personal property like furniture or equipment), (2) the improvements are owned by or revert to the landlord at lease expiration, and (3) the allowance is used within the period from the date of the lease to 60 days after the end of the tax year in which the lease expires. If these conditions are met, the tenant does not recognize the allowance as income, and the landlord depreciates the improvements.

If the conditions under IRC 110 are not met (for example, the tenant retains ownership of the improvements), the allowance may be treated as a lease inducement, which is taxable income to the tenant. The tenant then depreciates the improvements under the applicable MACRS recovery period (15 years for qualified improvement property under IRC 168(e)(6), eligible for bonus depreciation under IRC 168(k) as made permanent by OBBBA).

Qualified improvement property (QIP). Interior improvements to nonresidential real property are classified as QIP with a 15-year MACRS recovery period and are eligible for 100% bonus depreciation (made permanent by the One Big Beautiful Bill Act). This means a restaurant operator who spends $300,000 on an interior buildout can deduct the full amount in the year the improvements are placed in service, subject to sufficient income to absorb the deduction (or the deduction creates or increases a net operating loss that carries forward).

What lease terms are negotiable?

Base rent escalation. Most leases include annual rent increases of 2-3% or CPI-linked increases. Fixed increases are preferable to CPI increases because they are predictable. A restaurant operator who negotiates a 5-year term with 2% annual increases has a known rent trajectory; one with CPI increases may face 5-7% annual increases in inflationary periods.

Lease term and options. A restaurant needs at least a 10-year term (including options) to amortize the buildout cost. The most common structure is a 5-year initial term with two 5-year renewal options. The renewal options should be at a predetermined rent (fixed increase from the base, not market rate), or the tenant risks losing the location when the option comes up.

Exclusive use clause. Prevents the landlord from leasing to a competing restaurant in the same property or shopping center. The definition of “competing” should be specific: another Italian restaurant, another pizza restaurant, not just “any restaurant.” Without an exclusive use clause, the landlord can lease the adjacent space to a direct competitor.

Personal guarantee. Landlords typically require a personal guarantee from the restaurant operator (the individual, not just the LLC or corporation). The guarantee should be limited: capped at a specified dollar amount (12-24 months of rent), with a burn-off provision (the guarantee reduces or terminates after a specified period of on-time payment), and excluding consequential damages.

Assignment and subletting. The lease should allow the tenant to assign the lease or sublet the space (with landlord consent, not to be unreasonably withheld) in case the operator decides to sell the business. Without an assignment clause, the operator may not be able to transfer the lease to a buyer, which reduces the business’s sale value.

How are lease payments deducted?

All lease payments (base rent, NNN charges, percentage rent) are deductible as ordinary and necessary business expenses under IRC 162. The timing of the deduction:

Cash method: Deductible when paid. Advance rent (paid at lease signing for the first and last months) is deductible in the period it covers, not when paid, under the 12-month rule.

Accrual method: Deductible when the liability is established and economic performance occurs (ratably over the rental period). If the lease has escalating rent (increasing annually), the total rent over the lease term is typically deducted ratably (straight-line) over the lease term under IRC 467 for tax purposes, even if the actual payments increase. This is the “section 467 rental agreement” rule, and it applies to leases with increasing or decreasing rent where the total rent exceeds $250,000.

Security deposits. A security deposit is not deductible when paid because it is a refundable deposit, not an expense. If the landlord applies the deposit to unpaid rent or damages, the amount applied becomes deductible at that point.

What should I do next?

Before signing a restaurant lease, calculate the total occupancy cost (base rent + NNN + estimated percentage rent) as a percentage of projected gross sales. If the total exceeds 10% of projected sales, the lease economics do not support the concept at that location. If you are in a NNN lease and have never audited the CAM reconciliation, request the landlord’s backup and verify the charges.
