What is the difference between a tenant disputing a CAM charge and a tenant not paying?

A dispute is a substantive objection to the calculation — the tenant is contesting the amount. Non-payment is a collection issue — the tenant owes the amount but has not paid. These must be handled on separate tracks. For a tenant who disputes but owes an undisputed portion, the landlord should demand payment of the undisputed amount while the dispute is being resolved. For pure non-payment with no dispute, proceed directly to demand letters.

CAM Demand Letter Workflow for Landlords: From True-Up to Collection

Q: What is a CAM true-up demand letter?

A CAM true-up demand letter is a formal written notice to a tenant who has not paid their annual CAM reconciliation balance after the initial true-up invoice was issued. It references the lease obligation, the amount due, the original invoice date, and a cure period — typically 10 business days — after which the landlord may invoke the lease default remedies.

Q: Can a landlord offset unpaid CAM true-ups against future rent?

It depends on the lease. Some leases explicitly authorize the landlord to offset unpaid CAM balances against the next rent payment after a demand period expires. Other leases treat rent and CAM as separate obligations and do not allow offset. Review the lease's remedies section and the CAM provisions before attempting an offset — doing it without lease authority can create a rent default claim by the tenant.

Q: How should a landlord respond when a tenant invokes their audit right during the collection period?

A tenant who invokes audit rights during the collection period is typically entitled to suspend payment of the disputed amount pending the audit outcome. The landlord should: (1) acknowledge the audit request in writing within the lease-specified period, (2) confirm whether the full amount or a disputed portion is subject to the audit, (3) continue collecting any undisputed portion, and (4) begin assembling the audit defense packet.

Sending the reconciliation statement is only the beginning. A disciplined 4-stage collection workflow — from initial invoice to legal escalation — ensures true-up balances get collected without creating lease default disputes.

The 4-Stage CAM Collection Workflow

The CAM demand letter workflow has 4 stages: (1) send the initial true-up invoice with the reconciliation statement, (2) issue a 30-day payment reminder, (3) send a formal demand letter at 45–60 days, and (4) escalate to legal action or rent offset at Day 60+. Running a consistent process across all tenants protects the landlord from selective enforcement claims and creates a clear audit trail.

Dispute vs. Non-Payment: Handle These Separately

Before running the collection workflow, classify each tenant into one of two tracks. Mixing the tracks leads to waived collection rights and lease enforcement problems.

Dispute Track

The tenant objects to the calculation — they believe the amount is wrong. Do not immediately proceed to demand letters. Instead, respond to the substantive objection, provide supporting documentation, and separate the undisputed portion from the disputed portion. Demand payment of the undisputed amount while the dispute is resolved.

Non-Payment Track

The tenant has not objected to the amount but has not paid. This is a pure collection matter. Proceed through the 4-stage workflow below without waiting for a response to substantive questions. Non-response is not a dispute — it does not pause the collection clock.

The 4-Stage Collection Workflow

Initial True-Up Invoice

Day 0 — Delivered with the reconciliation statement

The true-up invoice should be delivered simultaneously with the reconciliation statement. Sending the statement without an attached invoice leaves the payment obligation ambiguous and allows tenants to claim they were unaware a payment was due.

Cover letter should include:

Clear statement that the reconciliation is complete and payment is due
The net true-up amount (owed by tenant) or credit amount (owed to tenant)
The payment due date — typically 30 days after delivery
Payment instructions (check payable to, wire instructions, or portal link)
Contact information for questions (not an invitation to dispute — a resource for clarification)

Supporting docs to attach: Expense schedule, management fee calculation, pro-rata share schedule, gross-up workbook (if applicable), cap bank schedule (if applicable). Attaching them upfront reduces follow-up requests by 60–70%.

Payment Reminder

Day 25–30 — Before the payment deadline

Send a payment reminder 5 days before the payment deadline — not after it. Tenants who have not yet paid sometimes simply forgot; a pre-deadline reminder closes the collection loop without requiring a formal demand letter.

Reminder email language:

"This is a courtesy reminder that your CAM reconciliation true-up payment of $[AMOUNT] for the period ending December 31, [YEAR] is due on [DATE]. If payment has already been sent, please disregard this notice. If you have questions about the reconciliation statement, please contact [NAME] at [EMAIL]."

Reference the original invoice number and date
State the outstanding amount and the due date
Confirm mailing address if payment is by check
Include a link to the original statement for reference

Formal Demand Letter

Day 45–60 — After payment deadline passes without payment

The formal demand letter is a legal document that begins the cure period clock. It must reference the lease section that creates the payment obligation and state the consequences of continued non-payment.

Required elements:

Reference the lease section creating the CAM payment obligation (e.g., Section 5.3, Additional Rent)
State the amount due, the original due date, and the number of days past due
Specify the cure period — typically 10 business days from receipt
State the consequences of non-cure: default, interest at the lease rate, right to offset against rent, or escalation to counsel
Send via the notice method specified in the lease (certified mail, overnight courier, or a combination)
Retain proof of delivery

Have the formal demand letter reviewed by your property counsel before sending — especially the first time for a property or lease. Cure period language must match the lease's default section exactly.

Escalation

Day 60+ — After cure period expires without payment

If the cure period expires without payment, the landlord has several options. The right choice depends on lease language, the tenant relationship, and the size of the balance.

Rent offset

If the lease permits, offset the unpaid CAM balance against the next rent payment. Requires explicit lease authority — do not attempt without confirming the provision exists.

Collections counsel

Engage property counsel to send a final demand and pursue collection through court action if needed. Appropriate for balances above $5,000–$10,000.

Commercial collections

For smaller balances, a commercial collections firm may be more cost-effective than litigation. Confirm the lease allows assignment of the claim.

What Can Go Wrong

Sending the demand letter without tracking prior notice

If the landlord cannot produce delivery confirmation for the original statement and reminder notices, the tenant can argue the demand period never started. Courts routinely dismiss collection claims where the landlord cannot prove when notice was delivered. Document every delivery at every stage.

Treating a dispute as non-payment

Sending a formal demand letter to a tenant who has raised a good-faith dispute — and has not received a substantive response — can be characterized as harassment or bad faith dealing. It also strengthens the tenant's litigation position. Separate the dispute response from the collection workflow and do not escalate to demand letters while a substantive response is pending.

Cure period language that does not match the lease

If the formal demand letter states a 10-day cure period but the lease requires a 15-day cure period, the demand is technically defective. A tenant with counsel will use this to restart the clock and delay collection by another month. Always extract the cure period from the lease's default section and use the exact number of days specified.

Frequently Asked Questions

What is a CAM true-up demand letter?

A formal written notice to a tenant who has not paid their CAM reconciliation balance. It references the lease obligation, the amount due, and gives a cure period — typically 10 business days — after which the landlord may invoke lease default remedies.

What is the difference between a dispute and non-payment?

A dispute is a substantive objection to the calculation. Non- payment is a collection issue — the amount is correct but unpaid. These must be handled on separate tracks. For disputes, respond to the substance and demand payment of the undisputed portion. For non-payment with no dispute, proceed directly through the 4-stage collection workflow.

Can a landlord offset unpaid CAM true-ups against future rent?

It depends on the lease. Some leases explicitly authorize offset; others treat rent and CAM as separate obligations. Review the lease's remedies section before attempting an offset — doing it without lease authority can create a rent default claim by the tenant.

How should a landlord respond when a tenant invokes audit rights during the collection period?

Acknowledge the audit request in writing within the lease-specified period. Confirm whether the full amount or only a disputed portion is subject to the audit. Continue collecting any undisputed portion. Begin assembling the audit defense packet — the landlord who has documentation ready wins the audit.
