Auditing landlord operating expense charges requires knowing your exact lease rights: what is included in CAM, what is excluded, your pro-rata share, your cap provisions, and your audit rights window. Without extracting these terms from the lease, tenants often fail to identify overbillings they are contractually entitled to dispute.
Upload your executed lease including all amendments and exhibits to Lextract.
Lextract identifies your pro-rata share, CAM definition, exclusion list, controllable expense cap, gross-up provision, and audit rights clause including the lookback period.
Verify that all exclusion items and CAM caps have been correctly extracted. These are often in exhibits and may be missed if the exhibit structure is non-standard.
Export the CAM provisions as a structured Excel reference document for your auditor.
Share the extracted lease rights summary with your auditor. The auditor compares landlord's actual charges against your lease entitlements to identify overbillings. After extraction, tenants can run a 14-rule CAM audit at <a href="https://www.camaudit.io" target="_blank" rel="noopener noreferrer">CAMAudit.io</a>.

Lextract extracts your audit rights clause, which specifies the lookback period — typically 1–3 years after receipt of the annual CAM reconciliation statement. Beyond that window, your audit rights may be contractually barred.
