Restaurant CAM Overcharges: What Small Owners Miss on NNN Leases

Restaurant tenants sign some of the most landlord-favorable NNN leases in commercial real estate. The combination of below-market base rents (offset by percentage rent clauses), intense competition for desirable locations, and short negotiating timelines pushes restaurant operators into leases with broad CAM pass-through provisions, minimal exclusion lists, and no caps on controllable expenses. For a single-location operator with $1.2 million in annual sales, a $15,000 CAM overcharge represents nearly a full point of profit margin.

Most small restaurant owners never audit their CAM charges. The reasons are predictable: the bill arrives during a busy quarter, it looks official, and the cost of a traditional audit doesn't pencil out on a 1,800-square-foot space. The result is a persistent pattern of overcharges that go unchallenged for years.

The four most common CAM overcharge patterns in restaurant leases are: excluded service charges bundled into the operating pool, management fee structures that exceed lease caps or operate on a fee-on-fee basis, controllable expense cap violations, and percentage rent interactions that affect the CAM base calculation.

Restaurant CAM Benchmarks

Restaurant tenants in strip centers and community shopping centers typically pay $8–$15/SF in CAM annually, reflecting the outdoor maintenance, parking lot resurfacing, and landscaping that characterize these properties. ICSC research data (2024) places average CAM for food service tenants in anchored strip centers at $9.40/SF.

For a 2,000-square-foot fast-casual restaurant paying $10/SF in CAM, that's $20,000 annually in pass-through charges. A 10% overcharge — a manageable error rate — represents $2,000 per year. Over California's 4-year lookback window, that's $8,000 in recoverable overcharges. Over a 6-year lookback in most other states, $12,000.

The Four Overcharges Restaurant Owners Miss

1. Excluded Services Buried in "Operations" Line Items (Rule 2)

Most restaurant leases include an exclusion schedule — a list of costs the landlord cannot pass through. Typical exclusions include management company overhead not related to property operations, costs associated with vacant suites (marketing, showing, renovation for re-leasing), and capital improvements with useful lives exceeding one year.

Landlords whose accounting systems consolidate expenses at the portfolio level sometimes include excluded items — particularly marketing costs, leasing commissions, and capital HVAC replacements — as operating line items without separating them from recurring maintenance. A $120,000 HVAC system replacement for the anchor tenant's kitchen exhaust infrastructure gets coded as "mechanical maintenance" and distributed to all tenants.

What to check: Any line item labeled "operations," "mechanical," "exterior maintenance," or "administrative support" warrants a request for underlying vendor invoices. The invoice will identify what work was actually performed and who it served.

2. Management Fee Stacking and Cap Violations (Rule 3)

Restaurant leases in strip centers frequently include both an on-site management fee (a percentage of gross revenues) and a separate "administrative" or "supervisory" fee. The management fee provision in most restaurant leases caps the percentage at 4–6%. The administrative fee often does not have a separate cap.

The overcharge structure is:

Management fee: 5% of gross revenues = $45,000 (on a $900,000 annual rent roll)
Administrative fee: 2% of gross revenues = $18,000
Total: $63,000 — but the lease may only permit one fee category totaling 6%, which would be $54,000

If the combined fees exceed the lease's management fee cap, the difference is an overcharge. The issue is that many restaurant leases were drafted to cap "the management fee" without anticipating that landlords would add separately labeled fee categories.

What to check: Add up every fee category — management, administrative, supervisory, asset management, coordination — and compare the total against the single management fee cap in your lease. If the aggregate exceeds the cap, the excess is recoverable.

3. Controllable CAM Cap Violations (Rule 13)

Many restaurant leases include a controllable expense cap — typically 5–8% annual growth in expenses the landlord can directly manage (maintenance, landscaping, security). The cap protects tenants from aggressive billing growth.

The overcharge occurs when landlords reclassify controllable expenses as non-controllable to avoid the cap. Landscaping contracts labeled as "natural area management"; parking lot maintenance coded as "environmental compliance"; security labeled as "safety infrastructure." Each reclassification moves an expense outside the cap calculation.

California's SB 1103, effective January 1, 2025, created new disclosure requirements for small-business commercial tenants including enhanced transparency in CAM billing. While it does not mandate caps, it requires landlords to itemize and substantiate CAM charges in ways that make cap violation detection easier.

What to check: Build a year-over-year comparison of controllable expenses. If the growth rate exceeds your cap, the excess is an overcharge. Focus on line items with sudden description changes between years — reclassification often shows up as a label change without any corresponding change in the underlying vendor contract.

4. The Percentage Rent Interaction Problem (Rule 3)

Some restaurant leases include both a management fee and a percentage rent clause (a percentage of gross sales above a "breakpoint"). When the management fee base includes percentage rent receipts, the landlord effectively collects a fee on variable income that was not anticipated in the fee calculation at lease execution.

The mechanism: Restaurant generates $1.8M in sales; breakpoint is $1.2M; percentage rent is 5% of the excess, or $30,000. If the management fee is 5% of "all gross revenues received by Landlord from the property" — and the landlord includes percentage rent in gross revenues — the management fee base is inflated by the tenant's own percentage rent contribution.

Case Law

Dinnerware Plus, Inc. v. Silverthorne Partners

In this retail strip center dispute, a restaurant tenant challenged management fees that included charges from an administrative services subsidiary of the landlord's property management company. The court examined whether the lease's management fee cap extended to fees charged by related entities. The landlord's argument — that affiliated entity fees were distinct from the management fee — was rejected; the court aggregated all fees from entities controlled by the landlord's management company for purposes of the cap.

California SB 1103 (Effective January 1, 2025)

While not a judicial decision, SB 1103 establishes new disclosure rights for small-business commercial tenants in California. Under the statute, tenants with fewer than 10 employees are entitled to written notice of CAM charge components and the methodology used to calculate them. For restaurant tenants — who are disproportionately small businesses — this creates a statutory basis for information requests that formerly required lease-level audit rights to trigger.

What to Do If You Find an Overcharge

Document the discrepancy with specific figures — what was billed, what the lease permits, and the mathematical difference
Send a written audit notice under your lease's audit rights clause (usually requires certified mail with a specified lead time)
Request the underlying vendor invoices and property management agreements for the disputed line items
Once the documents arrive, produce a formal reconciliation showing the overcharge
Send a demand letter requesting credit or refund — the tone can be collaborative or more formal depending on your relationship with the landlord

Frequently Asked Questions

Do restaurant tenants really have audit rights?

Most commercial leases include an audit rights clause that lets the tenant examine the landlord's supporting records for CAM charges within a specified window — usually 90 to 180 days after receiving the annual reconciliation. If your lease doesn't include an explicit audit rights clause, general contract principles still entitle you to demand documentation supporting the charges you're obligated to pay. Send a formal written request citing the reconciliation as the basis.

What happens if I miss the audit window?

Missing the lease's audit window does not necessarily forfeit your right to claim overcharges under the applicable statute of limitations. Many courts have held that a landlord-imposed audit window shorter than the state SOL is unenforceable as applied to claims that arose from the landlord's own misrepresentation. However, it complicates your claim and may require you to establish the error through other evidence. Act within the audit window whenever possible.

How does percentage rent affect my CAM exposure?

Percentage rent is generally separate from CAM billing. However, if the management fee is calculated on all landlord revenues (including percentage rent), you may be paying a management fee on your own variable rent contribution. Review the management fee base definition carefully and confirm that "gross revenues" excludes amounts the tenant pays as percentage rent.

Can I withhold CAM payments during a dispute?

In almost all commercial leases, no. Commercial leases in most states follow the independent covenant doctrine — rent and CAM obligations are independent of the landlord's obligations, meaning you must continue paying even if the landlord is in breach. Withholding CAM can give the landlord a valid eviction basis. The correct path is to pay under protest and pursue the overcharge claim separately.
