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.
