CAM Audit in San Francisco, CA

Last updated: April 2026

Commercial tenants in San Francisco pay an average of $11.80/SF in CAM charges each year. Under California law, you have 4 years to recover overpayments, but that window shrinks with every reconciliation cycle you let pass. CAMAudit runs 14 forensic detection rules on your reconciliation statement in under fifteen minutes to find overcharges before time runs out.

Definition

CAM Reconciliation

A CAM reconciliation is a landlord's annual statement comparing estimated CAM payments collected throughout the year against actual operating costs for the property. In San Francisco, commercial tenants under NNN and modified-gross leases receive this statement once a year, typically 60 to 120 days after the calendar year closes. The reconciliation lists every expense category the landlord allocated to tenants: management fees, insurance, property taxes, utilities, janitorial, landscaping, and more. If actual costs exceeded estimates, the tenant owes the difference. If estimates exceeded actuals, the tenant gets a credit. The problem is that landlords calculate these figures using methods that may not match what the lease permits, and most tenants sign off without checking. CAMAudit runs 14 detection rules on your San Francisco reconciliation to find every discrepancy before you waive your right to dispute.

“I built CAMAudit because tenants in San Francisco were paying $11.80/SF and had no fast way to check their landlord's math. A $79 audit that takes fifteen minutes should be standard practice, not a luxury.”
