CAM Charges Dispute Letter Workflow
A structured dispute process protects both sides — and produces better outcomes than informal objections
When a tenant receives a CAM reconciliation statement containing charges they believe are incorrect, a structured dispute process produces better results than an informal phone call. This workflow covers identifying and documenting specific errors, drafting a formal written dispute, and tracking the landlord's response through to resolution. Both tenants initiating disputes and landlords receiving them benefit from following a consistent process.
Step-by-Step Process (5 steps)
Identify Specific Errors in the Reconciliation Statement
Within 30–60 days of receiving the statementReview the reconciliation statement line by line against your lease. Identify specific categories of error: expenses that should be excluded under the lease exclusion list (management fees above the cap, capital expenditures, non-building expenses); incorrect gross-up threshold or methodology; cap type or base year inconsistency; wrong pro-rata denominator; arithmetic errors; or estimated payments not properly credited. Each identified error should reference the specific lease section that governs it.
Common errors at this step:
- • Disputing a total amount without identifying specific errors — the landlord cannot meaningfully respond to a vague objection
- • Conflating legitimate errors (included excluded expenses) with interpretive disputes (ambiguous lease language) — they require different responses
- • Not checking whether the error repeats across multiple prior years still within the audit window
Gather Supporting Evidence
Concurrent with error identificationBefore sending a dispute letter, compile the evidence for each identified error: the relevant lease clause (with page and section citation), the prior year's reconciliation statement (for consistency comparisons), any market benchmarks for expense categories that appear inflated, correspondence about lease amendments that should affect CAM, and your own calculations showing the correct figure.
Common errors at this step:
- • Sending a dispute letter without supporting documentation — unsubstantiated disputes are easy to reject
- • Relying on the reconciliation statement alone without requesting the underlying GL detail — the error may not be visible without the supporting data
- • Not retaining copies of all prior years' reconciliation statements — these are critical for identifying systematic overcharges
Draft and Send a Formal Written Dispute
Within the lease's dispute or audit window (typically 30–60 days of receiving the statement for a dispute, 12–24 months for an audit request)Write a formal dispute letter that: (1) identifies the reconciliation year and property; (2) lists each disputed item with the specific lease section that supports your position; (3) states the dollar amount of each discrepancy; (4) attaches or references your supporting documentation; and (5) requests a written response within a specified period (typically 30 days). Send via the notice method required by your lease and retain proof of delivery.
Common errors at this step:
- • Sending the dispute by email when the lease requires certified mail for notices — may not be a valid dispute under the lease
- • Not specifying a response deadline — the landlord has no urgency to respond
- • Including threats of litigation in the initial dispute letter before attempting resolution — this escalates unnecessarily and may slow settlement
Landlord Review Period and Response
30–60 days after dispute letter is receivedThe landlord (or property manager) reviews the dispute, pulls the reconciliation workpapers, and prepares a written response. A good-faith response will: acknowledge any clear errors and propose a credit; explain the methodology for disputed items with lease references; and request additional time if documentation needs to be retrieved. From the tenant's perspective, if no response is received within 30–45 days, send a follow-up in writing.
Common errors at this step:
- • Landlord responding verbally without a written acknowledgment — verbal agreements about billing disputes create future problems
- • Landlord conceding errors without issuing a corrected statement — a credit applied without documentation is difficult to verify
- • Tenant accepting a partial response as final without addressing all disputed items
Resolution — Correction, Credit, or Escalation
30–90 days after landlord's initial response; 90–180 days for escalated disputesIf the landlord concedes errors: obtain a corrected reconciliation statement and written confirmation of the credit or refund amount, including timeline. If the landlord disputes your position: evaluate whether the disagreement is factual (evidence will resolve it) or interpretive (lease language is ambiguous). For material amounts, engage a CAM auditor or real estate attorney. If negotiation fails, most commercial leases provide for arbitration before litigation.
Common errors at this step:
- • Accepting a credit that does not match the calculated overcharge — get the math in writing before agreeing to a number
- • Escalating to litigation before exhausting lease-required dispute resolution steps (arbitration, mediation) — may waive rights or create procedural defects
- • Not documenting the final resolution — future ownership changes or audits may resurface the same issue
Timeline
Simple disputes where the landlord acknowledges an error typically resolve in 30–60 days. Disputes requiring documentation exchange and negotiation: 60–120 days. Disputes escalated to outside auditors or arbitration: 6–18 months. The clock starts when the reconciliation statement is received — do not delay the initial dispute letter.
Where CapVeri Fits
CapVeri's independent recalculation provides the quantified, documented evidence a dispute letter requires. Rather than asserting that charges seem wrong, you can attach a CapVeri calculation trace showing exactly where the landlord's figures deviate from the lease terms — gross-up threshold applied, cap base year used, expenses included vs. the lease exclusion list. This changes the tone of a dispute from accusation to documentation.
