What Tenants Need to Know About CAM Reconciliation
CAM Reconciliations: A Small Detail That Can Cost Tenants Real Money
Each year, commercial tenants receive Common Area Maintenance (CAM) reconciliation statements. These statements compare the operating expenses a landlord estimated during the year against the actual costs incurred. Reconciliations are often delivered in the first part of the year after year-end. Exact timing depends on the lease, but we typically see delivery in late March or early April.
This statement may show that costs were close (i.e., budgeted and actual did not vary much), or it may show that you (the tenant) owe the landlord for a significant shortfall, or, less frequently, costs came in lower and you are owed money (or have a credit on your next bill).
Either way, the statement deserves attention.
What is Included in CAM?
“CAM” can mean slightly different things depending on the market and the lease. In many commercial leases, it is used broadly to describe operating expenses passed through to tenants. See our article on “What is CAM” for a more detailed definition.
In the context of reconciliations, understanding the difference between estimated monthly payments and the actual year-end statement is crucial to managing occupancy costs without surprises.
Why Tenants Should Review CAM Statements
Many tenants simply pay the bill and move on. That can be a mistake.
CAM reconciliations should be reviewed to confirm:
The charges are reasonable
The costs align with the lease
Excluded or capped expenses are not being passed through
Any unusual increases are properly explained
The tenant’s share, base year treatment, or gross-up methodology has been applied correctly where relevant
Even when the reconciliation is ultimately correct, the review gives the tenant a better understanding of occupancy costs. Additionally, finding an error in billing for the previous year can create value going forward by preventing repeat billing issues in future years.
Timing Matters
Most leases give tenants a limited period to dispute CAM charges, but that period varies. Many leases allow anywhere from 30 to 180 days after the tenant receives the reconciliation, with shorter windows requiring immediate attention.
If that window passes, the tenant may lose the right to challenge the statement. That is why CAM reconciliations should be reviewed promptly, not pushed aside until later. Whether a tenant has formal audit rights, and how those rights must be exercised, also depends on the lease language.
What to Look For
A good review goes beyond checking the math. Tenants should ask:
Are these expenses in line with prior years?
Do any line items seem unusually high?
Is there enough detail to understand what is being charged?
Does the lease carve out or cap any of these costs?
Has the landlord allocated the tenant’s pro-rata share correctly?
Are property taxes being contested if they appear excessive?
If needed, the tenant should request supporting documentation, including line-item detail, invoices, and tax backup, to the extent allowed by the lease or reasonably provided in the audit process.
Why the Lease Matters
The reconciliation is only part of the picture. The lease controls what can and cannot be passed through.
Some leases exclude certain costs, cap increases in controllable expenses, or require certain items to be handled differently. If the reconciliation is not reviewed against the lease, a tenant can end up paying more than required. Clear lease language is one of the main protections tenants have against excessive or unclear CAM charges.
A Desktop Audit Can Help
In many cases, a desktop review by a broker, lease administrator, or advisor is a practical first step. It can help identify whether the charges appear reasonable and whether a deeper investigation is warranted.
Not every review results in a refund, but many provide useful clarity. And in some cases, they uncover errors worth disputing. Lease-audit guidance also notes that the benefit is often not just recovering money, but improving future billing accuracy as well.
Final Thought
CAM reconciliations are an important part of managing occupancy costs. They may not get much attention, but they should. There are many factors at play. Change in property management, sale of the building to a new owner during the year, or significant repair or maintenance projects are all causes for ensuring costs have been appropriately passed through.
A timely review can help tenants catch errors, enforce lease protections, and avoid paying expenses they do not actually owe.
