Disputing a CAM charge starts with auditing the reconciliation. This 5-step guide walks you through it, with a free dispute letter draft template.
TL;DR: Dispute CAM charges in 5 steps: audit the reconciliation, document each overcharge with lease citations, issue a formal dispute letter draft, negotiate with the property manager, and escalate to mediation or litigation if unresolved. Most disputes resolve in 30 to 90 days when documentation is specific and calculation-backed.
Run the audit before you decide whether this applies to your lease.

CAM Dispute Process
The structured sequence a commercial tenant follows to formally challenge errors in a landlord's Common Area Maintenance billing: auditing the reconciliation, documenting overcharges with lease citations, issuing a written dispute letter draft, negotiating a resolution, and escalating if the landlord does not respond.
To dispute CAM charges: (1) Run an audit on your reconciliation statement to identify errors, (2) document each overcharge with lease citations, (3) issue a formal dispute letter draft, (4) negotiate with your landlord's property manager, (5) escalate to mediation or legal action if unresolved. Most disputes resolve in 30–90 days.
Before issuing any dispute, you need to know exactly what you are disputing and why. Vague objections do not create enforceable claims. Specific, calculation-backed findings do.
The audit compares your landlord's billing against what your lease actually permits. Two categories of errors exist:
Math errors are calculation mistakes verifiable with arithmetic:
Classification errors require comparing expense descriptions against your lease's inclusion and exclusion lists:
CAMAudit runs all 13 forensic detection checks automatically from your uploaded documents. Alternatively, you can run each check manually using your lease and the reconciliation general ledger.
What you need:
Critical timing: Know your dispute window. Check the lease section labeled "Audit Rights" or "CAM Dispute" for the deadline after statement delivery. This is commonly 30 to 180 days. Do not start the audit too close to this deadline to have no time left to send the letter.
Documentation is what separates a dispute that resolves in 30 days from one that drags for 6 months. For each error found, create a finding record containing:
The error type. Name it specifically: "Management Fee Overcharge," "Capital Improvement Included in CAM," "Gross-Up Applied to Fixed Expenses."
The lease provision violated. Quote the relevant section: "Section 7.3(b) limits management fees to 4% of controllable expenses, defined in Section 7.1 as operating expenses excluding taxes, insurance, and capital items."
The amount billed. State the dollar amount from the reconciliation.
The amount permitted. Show your calculation: "4% × $285,000 controllable expenses = $11,400 permitted."
The overcharge amount. Subtract: "Amount billed ($14,250) minus amount permitted ($11,400) = overcharge of $2,850."
Supporting documentation. Note what backup documents you have (invoices, certificates, worksheets) and what you have requested but not yet received.
A finding record for each overcharge gives your dispute letter draft its factual backbone and creates a paper trail you can reference if the dispute escalates.
The dispute letter draft is your formal notice. It creates a contractual obligation for the landlord to respond. Without it, even a valid overcharge can be deemed accepted.
What the letter must include:
Delivery method matters. Send by certified mail with return receipt, by overnight courier with confirmation, or by email with read-receipt and follow-up confirmation. You need proof of delivery because the landlord's response period starts from the date they receive the letter.
Do not withhold rent. Even if you have valid overcharges, withholding rent is a lease default in virtually every commercial lease. Pay the billed amount under protest if you wish, but do not stop payment while the dispute is open.
CAMAudit auto-generates the dispute letter draft with all findings, calculations, and lease citations pre-populated after completing the audit. You can select Collaborative, Neutral, or Aggressive tone and download as PDF or DOCX.
After sending the letter, you wait for a response. During this period:
Set a calendar reminder for the landlord's response deadline (30 days after delivery, or per your lease).
Prepare for partial concession. It is common for landlords to agree on some findings and dispute others. The management fee overcharge may be accepted; the capital improvement exclusion may be contested. A partial settlement is still a win.
Understand landlord psychology. Property managers are not landlords. They manage properties on behalf of owners and deal with disputes as part of their job. They are not personally invested in fighting your findings, and most prefer to resolve disputes quickly rather than escalate to their clients. Be factual, specific, and professional. Personal accusations accomplish nothing.
Get settlements in writing. If the property manager verbally agrees to a credit, follow up immediately with a written confirmation email: "Confirming our conversation today: you have agreed to a rent credit of $8,400 reflecting the management fee and insurance overcharges identified in our dispute letter draft dated [date]. Please confirm in writing by [date]."
Conditional payment. If the landlord demands payment of the full billed amount before responding to the dispute, you can make payment "under protest" by including language in your payment: "Payment of $[amount] is made under protest pending resolution of the dispute notice dated [date] and does not constitute acceptance of the billed amounts as correct." This preserves your dispute rights while avoiding default.
If the landlord does not respond within the stated deadline, or rejects all findings without providing counter-calculations:
Follow up in writing. Send a second letter noting the missed deadline and restating your request for a response. This creates a clean record if escalation becomes necessary.
Mediation. Commercial lease disputes are well-suited for mediation. A neutral mediator facilitates a settlement discussion. Mediation is typically faster and cheaper than litigation, and many leases require it as a precondition to legal action. Check your lease for an ADR clause.
Small claims court. In many states, small claims handles commercial disputes up to $10,000–$25,000. No attorney required. Useful for smaller overcharge amounts.
Commercial litigation or arbitration. For larger amounts or unresponsive landlords, consult a commercial real estate attorney. If your lease has a fee-shifting provision (loser pays attorney fees), the leverage calculus changes significantly in your favor.
Lease non-renewal leverage. If your lease expires within 12 to 24 months, your decision on whether to renew is your most significant negotiating chip. A landlord facing a vacancy would rather settle a $15,000 dispute than lose a tenant. Use this leverage appropriately.
“Most disputes resolve within 60 days of the first letter when the letter is specific and well-documented. The ones that drag are usually missing specificity: the tenant knows something is wrong but cannot point to the exact provision and exact dollar amount. That specificity is exactly what CAMAudit produces.”
Sending a vague objection. "I think my CAM charges are too high" is not a dispute. You need specific findings, specific calculations, and specific lease citations.
Missing the dispute window. The most avoidable error. Mark your calendar the day you receive the reconciliation statement.
Disputing charges you cannot actually support. Challenging an expense you dislike rather than one your lease prohibits. The dispute must be grounded in the lease, not in your sense of fairness.
Waiting for all backup documentation before sending the letter. Send a preliminary dispute reserving your rights before the window closes, even if you have not received all invoices. You can supplement with additional findings as documentation arrives.
Withholding rent. This is a lease default even when you are right. Do not do it without legal counsel.
Accepting a vague settlement. "We will review and get back to you" is not a settlement. Get specific credits in writing with a timeline for application.
