What is the difference between a CAM cap and a controllable expense cap?

A CAM cap applies to all CAM expenses. A controllable expense cap applies only to expenses the landlord can manage, such as management fees, janitorial, landscaping, and security. Non-controllable expenses like taxes and insurance are excluded because landlords cannot control them. Controllable caps are more common than all-expense caps in modern commercial leases.

Is the CAM cap a simple annual limit or a cumulative cap?

Both types exist. An annual cap limits year-over-year growth, for example no more than 5% above the prior year's charges. A cumulative cap limits total growth from a base year, for example never more than 20% above the base year regardless of annual increases. Cumulative caps can be more tenant-favorable in periods of sustained inflation.

Can a landlord exclude certain expenses from the CAM cap?

Yes, caps typically exclude non-controllable expenses like real estate taxes, insurance premiums, and utility charges because these are driven by third parties. What counts as non-controllable should be explicitly defined in your lease. Landlords sometimes reclassify controllable expenses as non-controllable to avoid the cap.

What years do I need to prove a CAM cap violation?

You need the base year or prior year reconciliation statement and the current year reconciliation. CAMAudit uses both documents to calculate the year-over-year increase and compare it to the lease cap. If you are missing a prior year statement, request it from your landlord as part of your audit rights.

Math-Based Rule

CAM Cap Violation: How CAMAudit Calculates the Dollar Overcharge Above Your Lease Limit

Last updated: April 2026

If your lease has a CAM cap and your landlord exceeded it, every dollar above the cap is an overcharge that compounds annually. A 3% cap violation on a $50,000 controllable CAM pool means $1,500 in overcharges per year, every year the violation continues.

Definition

CAM Cap Violation

A CAM cap violation occurs when the annual increase in controllable CAM expenses exceeds the maximum percentage increase permitted by the tenant's lease. CAM caps protect tenants from unexpected spikes in operating costs by limiting how much controllable expenses can grow year over year, typically 3 to 5 percent annually from a base year. When actual expenses exceed the cap, the excess amount billed to the tenant is a quantifiable overcharge calculated by subtracting the capped ceiling from the actual charges in that expense category. CAMAudit's CAM cap detection rule extracts the cap percentage, the applicable base year, and whether the cap covers all expenses or only controllable expenses from the lease. It then pulls prior year CAM totals from uploaded reconciliation documents, applies the cap formula, and computes the exact dollar amount charged above the permitted ceiling for each reconciliation year in scope.

How CAMAudit Detects This

CAMAudit extracts the CAM cap provision from your lease, including the cap percentage, the base year or comparison year, and whether the cap applies to all expenses or only controllable expenses. CAMAudit distinguishes between annual caps, which limit year-over-year growth, and cumulative caps, which limit total growth from the base year across the full lease term.

CAMAudit's CAM cap detection rule retrieves the prior year's CAM reconciliation data from the documents you upload and calculates the maximum permitted charges for the current year by applying the cap percentage to the prior year's figures. When the actual charges exceed this ceiling, CAMAudit calculates the overage and flags it as a quantified overcharge with the specific dollar amount.

CAMAudit also checks whether the landlord correctly excluded non-controllable expenses such as taxes, insurance, and utilities from the cap calculation. A common error is applying the cap selectively to some line items while allowing other expense categories to grow without limit under a misclassification of controllable expenses as non-controllable.

Real-World Example

A restaurant tenant's lease capped controllable CAM increases at 5% annually. Prior year controllable CAM charges were $28,400. The 5% cap set the ceiling for the current year at $29,820. The reconciliation showed $34,100 in controllable expenses. CAMAudit calculated the overage: $34,100 minus $29,820 equals $4,280 in overcharges for that reconciliation year.
