CAM Audit Request Workflow for Tenants
Your lease gives you audit rights — here is how to use them effectively
Most commercial leases grant tenants the right to audit the landlord's CAM calculations, typically within 12–24 months of receiving a reconciliation statement. Tenants who suspect overbilling — whether from gross-up errors, excluded exclusions, or cap miscalculations — can initiate a formal audit process to recover overcharges. This workflow covers each step from identifying the right to audit through documenting the final resolution.
Step-by-Step Process (6 steps)
Review Your Lease Audit Rights Clause
Immediately upon receiving reconciliation statementLocate the audit rights provision in your lease. Note the audit window (typically 12–24 months after receiving the reconciliation statement), any notice requirements, whether the audit must be conducted by a CPA or licensed auditor, cost responsibility (tenant pays unless overcharge exceeds a threshold), and any limitations on the scope of review.
Common errors at this step:
- • Missing the audit window deadline — rights expire and are permanently waived
- • Engaging an auditor who does not meet the lease's qualification requirements (e.g., lease requires CPA but tenant hires a consultant)
- • Not checking whether prior years are still within the audit window — overcharges compound over multiple years
Send a Formal Written Audit Request
Within the lease audit window (typically within 12–24 months of receiving the statement)Send a written audit request to the landlord (and property manager if applicable) by the method required in the lease (certified mail is standard). The request should cite the specific lease section, identify the reconciliation year(s) being audited, and specify the documentation you are requesting. Retain proof of delivery.
Common errors at this step:
- • Sending the request by email when the lease requires written notice by certified mail — may not be a valid audit trigger
- • Not citing the specific lease section — a vague request may not toll the audit deadline
- • Requesting too broadly or too narrowly — the landlord may object to scope
Obtain Supporting Documentation from the Landlord
30–60 days after audit requestRequest the landlord's full reconciliation workpapers: detailed GL trial balance for the reconciliation year, invoices and contracts for significant expense items, gross-up calculation worksheet, cap calculation worksheet, pro-rata denominator history, and any management fee backup. Most leases require the landlord to produce this documentation within 30–60 days of the audit request.
Common errors at this step:
- • Accepting a summary statement instead of the detailed GL — you cannot audit what you cannot see
- • Not following up when the landlord delays document production — the audit window may still be running
- • Failing to request invoices for the largest expense line items — these are where overbilling is most common
Conduct the Audit
30–90 days (depending on complexity and whether a third-party auditor is engaged)Review the landlord's documentation against the lease terms. Key areas: verify gross-up was applied only to variable expenses at the correct threshold; confirm cap type and base year are consistent with the lease; check that excluded expenses (management fees above the cap, capital items, non-building expenses) were not included in the recovery pool; verify pro-rata denominator matches the lease definition; confirm estimated payments and credits were applied correctly.
Common errors at this step:
- • Reviewing only the math without verifying what expenses were included — inclusion errors are more common than arithmetic errors
- • Not checking the gross-up threshold against the exact lease language — 90% vs. 95% is a material difference
- • Accepting the landlord's expense classifications without verifying against the lease exclusion list
Present Findings and Negotiate Corrections
Depends on audit duration; typically 60–120 days after audit requestPrepare a written findings report that identifies each overcharge, the specific lease clause that supports your position, and the dollar amount of the discrepancy. Send the report to the landlord with a request for correction. Distinguish between clear errors (incorrect math, included excluded expenses) and interpretation disputes (ambiguous lease language) — they are resolved differently.
Common errors at this step:
- • Presenting findings verbally without a written report — verbal agreements about CAM disputes are difficult to enforce
- • Combining errors and interpretive disputes in a single demand — landlords may concede errors but dispute interpretations; keep them separate
- • Not quantifying each finding individually — a lump-sum dispute demand is harder to negotiate and settle
Document Resolution and Track Credits or Refunds
30–60 days after findings are acceptedOnce the landlord acknowledges corrections, obtain a written confirmation of the agreed credit or refund amount, the reconciliation year(s) affected, and the timeline for applying the credit to future billings or issuing a check. Update your internal records to track when the credit is applied. For multi-year audits, verify each year's correction is applied separately.
Common errors at this step:
- • Not getting the resolution in writing — landlords may apply a different credit amount than agreed
- • Failing to track whether the credit is actually applied to future billings — it is easy to overlook a credit that never appears
- • Not confirming the resolution is final and that the landlord waives the right to revise the corrected statement
Timeline
Full CAM audit process: 3–9 months from initial request to final resolution for a single-year audit. Multi-year audits or disputes involving outside arbitration can extend to 12–18 months. The audit window under most leases runs from the date the reconciliation statement is received — do not delay initiating the process.
Where CapVeri Fits
CapVeri's independent recalculation engine can be used by tenants or their representatives to verify landlord calculations before or during an audit. Upload the landlord's reconciliation statement and supporting GL export; CapVeri recalculates gross-up, cap, and pro-rata share independently and flags discrepancies against the lease terms you input.
