Delinquent CAM Collections: Escalation from Late Notice to Legal Remedies

By Angel Campa, Founder, CapVeri

The Cost of Inaction

A 220,000 SF office building sent 26 reconciliation statements in March totaling $187,000 in true-ups. By June, $52,000 remained uncollected from five tenants. The controller hadn't sent a single collection notice because she was busy with the next quarter's estimates. By September — six months after invoicing — $38,000 was still outstanding. One tenant had vacated without paying. Another was in renewal negotiations and using the unpaid true-up as a bargaining chip.

Total cost: $22,000 written off (the vacated tenant), $8,000 conceded in the renewal negotiation, and 40+ hours of controller time managing the dispute. Total recovery: $8,000 of the original $38,000.

The $30,000 loss was entirely preventable. A structured collection process starting at day 10 would have flagged the delinquencies before they became losses.


The Escalation Ladder

Every unpaid CAM charge should move through a defined escalation sequence. Here's the framework, starting from the invoice date:

Day 0: Statement Delivery

The reconciliation statement is delivered with a clear due date — typically "net 30" from the statement date. The statement should include:

  • The calculation showing the true-up or credit amount
  • The due date in bold
  • Payment instructions (where to send the check or how to pay electronically)
  • A reference to the lease section governing CAM payments

Ambiguous due dates are the #1 cause of avoidable collection delays. "Due upon receipt" is unenforceable. "Due March 31, 2026" is clear.

Days 1–10: Grace Period

Most commercial leases include a 5–10 day grace period before late fees apply. During this period, no collection action is needed. Many tenants pay between days 25–35 as a matter of standard AP processing.

Day 11–15: Friendly Reminder

If the grace period has expired and payment hasn't arrived, send a brief, professional reminder:

This is a reminder that Invoice #2026-CAM-042 for $8,450.00 (2025 CAM reconciliation true-up) was due on March 31, 2026. Per Section 4.2 of your lease, a late fee of 5% ($422.50) applies to amounts not received within 10 days of the due date. Please remit payment at your earliest convenience.

Channel: Email to the tenant's designated contact, with a copy to your property manager.

Tone: Factual, not adversarial. Many late payments are simply AP processing delays.

Day 16–30: Phone Contact

If the reminder doesn't produce payment or a response, pick up the phone. Call the tenant's accounting contact (not the office manager or receptionist).

Purpose of the call:

  1. Confirm the statement was received
  2. Ask if there are questions about the charges
  3. Get a commitment to a payment date
  4. Document the conversation (date, who you spoke with, what they said)

Most delinquencies resolve at this stage. The tenant either (a) didn't receive the statement, (b) had a question they didn't raise, or (c) needs to process it through their AP cycle. A phone call resolves all three.

If the tenant disputes the charges, switch to your dispute resolution process. A dispute is not a collection issue — it's a calculation or documentation issue. Don't escalate collection on disputed amounts until the dispute is resolved.

Day 31–45: Formal Late Notice with Late Fees

If 30 days have passed with no payment and no dispute, send a formal written late notice via the lease-required notice method (usually certified mail or overnight delivery):

The notice should include:

  • The original invoice amount and date
  • The late fee calculation per the lease
  • The total amount now due (principal + late fees)
  • A reference to the specific lease sections governing additional rent and late fees
  • A clear deadline for payment (typically 10–15 days)
  • A statement that failure to pay constitutes a default under the lease

Example calculation:

ItemAmount
Original true-up invoice$8,450.00
Late fee (5% per Section 4.2)$422.50
Interest (1.5%/month x 1 month, per Section 4.3)$126.75
Total amount due$8,999.25

Day 46–60: Demand Letter

If the formal late notice doesn't produce payment, escalate to a demand letter. This can come from your property management team or — for larger amounts — from your attorney.

A demand letter should:

  • Recite the lease obligations (specific sections)
  • State the amount owed including all accrued fees and interest
  • Reference the formal late notice already sent
  • State that failure to pay within [X] days will constitute an Event of Default
  • Identify the remedies available to the landlord under the lease
  • Be sent via the lease-required notice method with proof of delivery

The demand letter is the last step before activating lease default provisions. It should be taken seriously, which means it should read like a legal document even if it's not coming from an attorney.

Day 61–90: Notice of Default

If the demand letter doesn't produce payment, issue a formal Notice of Default under the lease. This triggers the lease's cure period (typically 10–30 days) and preserves your right to pursue remedies.

The Notice of Default should reference:

  • The lease section defining Events of Default (failure to pay additional rent)
  • The specific obligation that was breached
  • The cure period and deadline
  • The remedies you will pursue if the default is not cured

Have your attorney review or draft this notice. An improperly drafted default notice can be challenged, which delays the process by months.

Day 90+: Legal Remedies

If the default is not cured within the cure period, you have several options depending on your lease and jurisdiction:

Option 1: Offset against security deposit. If the tenant posted a security deposit or letter of credit, draw against it for the amount owed. Notify the tenant and demand they replenish the deposit per the lease terms.

Option 2: Lease termination. Most commercial leases allow the landlord to terminate for uncured monetary default. This is a nuclear option — you lose the tenant and the revenue stream. Use it only when the tenant relationship is already unsalvageable.

Option 3: Lawsuit for amounts owed. File a breach of contract action for the unpaid additional rent, late fees, interest, and attorney's fees (if the lease provides for fee-shifting). This is appropriate for large amounts or tenants who are otherwise current on base rent but refusing to pay CAM.

Option 4: Set-off against tenant allowances or credits. If the tenant is owed any credits, TI allowances, or other payments from the landlord, offset the delinquent CAM amount. Confirm the lease allows this.

Late Fees: What Your Lease Allows

Late fee provisions vary by lease. Know what yours says before you need it:

Common structures:

Late Fee TypeTypical TermsExample on $8,450
Flat percentage5% of overdue amount$422.50 one-time
Monthly interest1–1.5% per month$126.75/month
Daily ratePrime + 3–5% per annum~$3.11/day
Combination5% flat + 1.5%/month$422.50 + $126.75/month

State law limitations. Some states cap late fees or require that they be "reasonable" in relation to the landlord's actual damages. California, for example, requires that late fees reflect a reasonable estimate of the costs incurred by the landlord. A 25% late fee on a $500 charge would likely be struck down. Know your jurisdiction's rules.

Late fees on CAM specifically. Some leases define late fee provisions under the base rent section and reference "additional rent" or "all sums due under this lease" in the late fee clause. Others are ambiguous. If your lease's late fee clause only references "rent" without defining whether that includes additional rent, get a legal opinion before assessing fees on CAM charges.


Special Situations

Tenant Disputes the Amount

A dispute is not a license to stop paying. Most leases require the tenant to pay the disputed amount (or the undisputed portion) while the dispute is resolved. If your lease includes this provision, remind the tenant in writing and continue the collection timeline on the undisputed portion.

Tenant Is in Financial Distress

If a tenant is unable to pay (as opposed to unwilling), consider a payment plan. Structured payments — $2,000/month for five months instead of $10,000 at once — may produce better recovery than a demand letter that gets ignored. Document the payment plan in a letter agreement that preserves your late fee rights if the plan is not followed.

Tenant Has Vacated or Is Vacating

Collect before the tenant leaves. Once a tenant has vacated and returned keys, your leverage drops significantly. If you know a tenant is not renewing, accelerate the reconciliation and deliver the statement before their lease expires if possible. Apply any security deposit to unpaid amounts immediately upon lease expiration.

Tenant Bankruptcy

If a tenant files for bankruptcy protection, all collection efforts must stop immediately (the "automatic stay"). Do not send demand letters, assess late fees, or take any collection action after a bankruptcy filing. Consult your attorney. CAM charges may be treated as administrative claims in bankruptcy, which can improve your recovery position.


Tracking Delinquencies

Maintain a receivables aging report for CAM true-ups separate from base rent aging. CAM receivables have different collection dynamics — they're seasonal (concentrated in Q1/Q2), often disputed, and may require different escalation timing.

CAM receivables aging report:

TenantInvoice DateAmountCurrent31–6061–9090+Status

Review this report weekly during Q1/Q2 (collection season) and monthly thereafter.
