CAM reconciliation statements arrive once a year, and landlords count on most tenants signing off without a thorough review. The charges look complicated, the backup is dense, and the audit rights window closes faster than most lease administrators realize. The result is that overcharges go unchallenged -- and uncollected -- year after year.
This checklist covers the 14 items every tenant should review before signing off on a CAM reconciliation statement. Work through each one systematically before issuing any payment or waiving your audit rights.
1. Verify the Gross-Up Clause Application
Gross-up provisions allow the landlord to inflate expense calculations to a hypothetical occupancy level (typically 90% to 95%) regardless of actual occupancy. The justification is that fixed costs should not be borne disproportionately by tenants in a partially vacant building.
What to check: Confirm the gross-up percentage matches what the lease specifies. Confirm that gross-up is applied only to variable expenses, not fixed costs. Confirm that only expenses that genuinely vary with occupancy are grossed up -- landlords sometimes gross up fixed property management fees, which is contractually improper if the lease does not allow it.
2. Check the CAM Exclusions List
Your lease should contain an explicit list of expenses excluded from the CAM pool. Common exclusions include capital expenditures, landlord legal costs, leasing commissions, and above-market management fees.
What to check: Pull the reconciliation line items and compare each to the exclusion list in your lease. Look for line items labeled "building improvements," "reserve contributions," or "special assessments" -- these frequently include capital costs that should be excluded. Ask for backup invoices for any line item over 5% of total CAM.
3. Confirm the Administrative Fee Cap
Many leases allow landlords to charge both a property management fee and a separate administrative overhead fee. Stacking these two charges effectively doubles the management cost passed to tenants.
What to check: Identify every management-related line item in the reconciliation. Add them up. Confirm the total does not exceed the cap stated in your lease. If your lease caps management fees at 5% of operating expenses, the combined total of management fee plus administrative fee should not exceed that cap. If it does, the excess is an overcharge.
4. Review Capital vs. Maintenance Classification
The distinction between a capital expenditure and a maintenance expense is one of the most contested areas in CAM audits. Replacing an HVAC unit is a capital expense; servicing it is maintenance. Repaving a parking lot is capital; patching it is maintenance.
What to check: Review every invoice or line item related to building systems, parking, roof, or major equipment. For any item above $10,000 per occurrence, request the supporting invoice. If the work extended the useful life of the asset rather than restoring it to its existing condition, it should be classified as capital and excluded from CAM (absent a specific amortized capital expenditure carve-out in your lease).
5. Audit the Management Fee Calculation
Property management fees are almost always stated as a percentage -- of gross revenue, of operating expenses, or of collected rent. The base on which the percentage is applied matters enormously.
What to check: Identify the management fee basis in your lease (gross revenue vs. operating expenses are the two most common). Recalculate the fee using the stated percentage and the correct base. Request documentation of the actual management fee paid if the property is managed by an affiliated entity -- related-party management fees must often be capped at market rate under the lease.
6. Check the Reconciliation Deadline
Most leases require the landlord to deliver the CAM reconciliation statement within 90 to 180 days after the calendar year ends. Missing this deadline has consequences: in some leases, a landlord who fails to deliver the statement on time forfeits the right to collect any year-end true-up.
What to check: Note the date on the reconciliation statement and compare it to the delivery deadline in your lease. If the statement arrived late, review the lease language for any cure period or forfeiture provision. If the landlord lost the right to collect a true-up, document this before making any payment.
7. Verify the Pro-Rata Share Calculation
Your pro-rata share is your square footage divided by the total rentable area of the building or project. A single incorrect denominator -- using the wrong gross leasable area or including areas that should be excluded -- can inflate your share by several percentage points.
What to check: Confirm the numerator (your square footage) matches the lease. Confirm the denominator (total building RSF) matches the lease definition. Check whether any spaces are excluded from the denominator under the lease -- some leases exclude anchor tenant spaces, storage areas, or kiosk areas. Recalculate your percentage independently and compare to the landlord's stated percentage.
8. Review the Controllable vs. Uncontrollable Expense Split
If your lease has a CAM cap on controllable expenses, the split between controllable and uncontrollable expenses directly determines how much of the CAM increase falls inside the cap. Landlords benefit from classifying as many expenses as possible as "uncontrollable" to avoid cap limitations.
What to check: Pull the lease definition of controllable vs. uncontrollable expenses. Verify each reconciliation line item against those definitions. Property taxes and insurance are almost always uncontrollable. Janitorial, landscaping, security, and repairs are almost always controllable. Watch for utilities being classified as uncontrollable when the lease does not support that classification.
9. Check Prior-Year True-Up Accuracy
The current year's estimated CAM payments were based on a budget, and the reconciliation adjusts for actual expenses. But the reconciliation should also reflect any credits or adjustments owed from prior reconciliations.
What to check: Compare the current reconciliation to last year's final reconciliation. Confirm that any credits or refunds owed from the prior period were applied. Verify that estimated payments made during the year are accurately reflected in the reconciliation. A landlord who carried over an unresolved prior-year dispute without applying the credit in the current statement is compounding the overcharge.
10. Confirm the Audit Rights Period
Your right to audit the CAM reconciliation has a defined window -- typically 12 to 18 months after delivery of the statement. If you sign off without noting your audit rights or if you wait too long, you may waive them.
What to check: Note the audit rights window stated in your lease. Calculate the deadline from the date the reconciliation was delivered. If you intend to audit, send written notice before the deadline even if the audit itself will happen afterward. Sending the notice preserves the right; conducting the audit can happen later. If the audit rights period has already expired, document why.
11. Review Insurance Allocation
Property insurance costs are a legitimate CAM expense, but the amount allocated must reflect the actual insurance cost for the property -- not a loaded figure that includes umbrella coverage for the landlord's broader portfolio, D&O insurance, or other non-property-specific policies.
What to check: Request the actual insurance certificate or declarations page for the property. Confirm that the premium allocated to the property is the actual cost for that specific location. Verify that any portfolio-level insurance premium is allocated fairly across properties by square footage or insured value, not arbitrarily assigned to your property.
12. Check Parking and Janitorial Allocations
Parking and janitorial costs are frequently misallocated, particularly in mixed-use properties or multi-building campuses where costs are pooled across properties.
What to check: Confirm that parking costs are allocated only to tenants who have access to or benefit from the parking areas. Confirm that janitorial costs reflect the actual scope of service for common areas in your building. In multi-building projects, verify that costs are not pooled in a way that allocates costs from buildings or improvements that your lease does not benefit from.
13. Verify Tax Appeal Credits
When a landlord successfully appeals a property tax assessment, the resulting refund or credit should reduce the CAM pool in the year it is received. Some landlords quietly pocket tax appeal proceeds rather than passing them through to tenants.
What to check: Ask whether any property tax appeals were filed or resolved in the reconciliation year. If a refund was received, confirm that it is reflected as a credit in the CAM pool. Review the reconciliation for any credit line items and verify that they were applied correctly. If the lease specifically addresses tax appeal credits, confirm the landlord followed that protocol.
14. Confirm the Cap Structure (Cumulative vs. Non-Cumulative)
If your lease has a controllable CAM cap, the structure of that cap -- cumulative vs. non-cumulative -- determines whether unused cap room carries forward.
What to check: Identify whether the cap is cumulative or simple. In a cumulative cap, if actual increases were below the cap percentage in prior years, the unused room carries forward and increases the allowable growth in the current year. In a non-cumulative cap, unused room does not carry forward. Recalculate the permitted increase for the current year using the correct structure and verify that the reconciliation amount does not exceed it.
What to Do When You Find a Problem
If your review identifies a discrepancy, document it precisely: identify the line item, the lease provision it violates, and the dollar amount of the overcharge. Send a written dispute notice to the landlord before making payment on the questioned amount -- or make payment under protest with a reservation of rights noted in writing. Engage a professional CAM auditor for any dispute that exceeds $5,000 or requires detailed invoice review. CAM auditors work on contingency and typically recover far more than their fee.
A structured lease abstract that captures CAM cap percentages, exclusion lists, audit rights windows, and management fee limits is the foundation for every reconciliation review. Without that data in hand, you are reviewing the landlord's statement against your memory of the lease rather than the actual contractual language.
