The CAM reconciliation playbook for multi-location portfolios

Common area maintenance is the most dispute-prone line in commercial real estate, and the reason is simple. CAM is reconciled once a year, often against the landlord’s summary rather than the governing lease, and the lease is where the caps, exclusions, and gross-up rules actually live. Overcharges hide in vague administrative fees and in capital improvements slipped into operating expense.

At a single location that is an annoyance. Across a multi-location portfolio it is a pattern: the same misclassification repeats site after site, and a single missed exclusion scales into serious money.

The playbook for catching it#

1. 01Pull the CAM terms from each lease: the inclusions, the exclusions, the caps, the gross-up rules, the pro-rata basis.
2. 02Reconcile the billed charges against those terms, not the landlord’s summary.
3. 03Flag every variance, with the governing clause attached as proof.
4. 04Pursue the recovery, and keep the audit trail for the dispute.

Doing this by hand at scale is the constraint, which is why accurate lease abstraction underneath matters, and why a line-by-line pass-through audit is the natural next step.
