Recovery of past CAM overcharges depends on your specific lease terms, including any audit rights deadlines or ‘binding and conclusive’ provisions, and on applicable state law.

State statute of limitations periods apply to written contracts and range from 3 to 10 years. Your actual lookback window may be shorter based on your lease.

Escalation Formula

Last updated: April 2026

The contractual method for increasing a tenant's CAM or rent charges year over year. Common escalation formulas include fixed percentage increases, CPI-based adjustments, and actual cost pass-throughs. The formula dictates how much more you pay each year.

Technical Definition

Escalation formulas are lease provisions that define the rate, method, and timing of periodic charge increases. They may be fixed (e.g., 3% annual increase), indexed (tied to CPI or another published index), or variable (actual operating expense increases passed through pro rata). Some leases combine methods, applying a fixed escalation to base rent while using actual cost pass-throughs for CAM.

How This Gets Abused

A lease specifies a 3% annual escalation on CAM, but the landlord applies the increase to the prior year's actual expenses rather than the base year amount. Over five years, compounding on actuals instead of the base produces charges thousands of dollars higher than the lease formula allows.

Tenant Protection Tip

Map out your escalation formula year by year from lease commencement. Compare each year's billed amount to what the formula should produce. Compounding errors in escalation formulas grow every year they go uncorrected.
