CAM Reconciliation Season: What to Expect and When [2026 Guide]
CAM reconciliation statements typically arrive January through April. Here is what triggers the statement, what deadlines to watch, and how to dispute before the window closes.
CAM Reconciliation Season: What to Expect and When [2026 Guide]
CAM reconciliation season runs January through April. Your landlord must deliver the annual reconciliation statement within 90–120 days of year-end. You typically have 30–180 days after that to dispute. Missing that window can significantly limit your options.
40%of commercial CAM reconciliations contain material billing errors that tenants could dispute with documentation
Most commercial leases run on a calendar year, making January through April the peak delivery window for annual reconciliation statements. Here is what typically happens each month:
Free scan · No account required
Run the audit before you decide whether this applies to your lease.
Year closes; final utility bills, management fees, and insurance invoices processed
January–February
Reconciliation statements issued for prompt-paying landlords; early dispute windows open for prior-year late statements
March
Peak delivery month for calendar-year leases; most tenants receive statements in this window
April–May
Late statements delivered; some landlords miss self-imposed or lease-mandated delivery deadlines
June–July
Dispute windows closing for January-delivered statements with 180-day windows
August–October
Escalation territory for unresolved disputes; mediation timelines active
November–December
Year-end again; prior-year disputes ideally resolved before new statements arrive
If your lease runs on a non-calendar fiscal year (common in retail), shift this calendar accordingly. A March 31 lease year-end means statements typically arrive June through August, with dispute windows extending into late fall.
What Triggers a Reconciliation Statement
The annual CAM reconciliation is triggered by the close of the lease year. Here is the chain of events:
Year-end close: The landlord's property management software closes the operating expense ledger for the period. All invoices, purchase orders, and management fee entries must post before this can happen.
Expense allocation: Operating expenses are allocated across tenants according to each tenant's pro-rata share (typically leased square footage divided by total rentable area). This step is where many errors originate, especially if the denominator calculation includes or excludes certain tenant types.
Estimate reconciliation: Your monthly CAM estimates (paid throughout the year) are compared against actual expenses. If actual costs exceeded estimates, you owe a true-up payment. If actual costs came in below estimates, you are owed a credit or refund.
Statement preparation: The property manager or accounting team assembles the reconciliation document, typically showing expense categories, totals, your pro-rata percentage, and the resulting balance.
Statement delivery: The reconciliation is delivered to you by mail, email, or through a tenant portal. The delivery date matters because it starts your dispute window clock.
One important note: many tenants assume they need to wait for the reconciliation to arrive before requesting backup documentation. They do not. You can request the supporting general ledger and invoices at any time after the lease year closes, not just after you receive the statement.
Typical Dispute Windows by Lease Type
Dispute windows vary significantly by lease type and how the audit rights clause is drafted. Always check your specific lease language, as these are general ranges:
Lease Type
Typical Dispute Window
Common Variations
Standard retail NNN
30–90 days after statement delivery
Some allow 6 months
Office (Class A multi-tenant)
60–180 days
May include 12-month audit right separate from dispute window
Industrial NNN
30–60 days
Often shorter, stricter
Ground lease
90–180 days
Typically more negotiable
Modified gross (MG)
30–90 days
Sometimes no formal dispute window if CAM is limited
REIT-managed properties
30–60 days
Standardized; REIT forms favor shorter windows
The "account stated" doctrine is the legal risk underlying all dispute windows. If you receive a statement, do not dispute it within the window, and make payment, some jurisdictions treat your payment as acknowledgment that the statement is correct. This is not a universal rule, and courts have split on how strictly to apply it in commercial lease contexts, but it is a real risk worth taking seriously.
What to Do When Your Statement Arrives
Red Flags in a Reconciliation Statement
When the statement arrives, scan for these warning signs before you do the full audit:
Management fee percentage higher than your lease cap. If your lease limits management fees to 4% and the statement shows 5%, that is a direct overcharge you can dispute immediately.
Year-over-year increase above your CAM cap. If your lease includes a controllable expense cap of 5% and total controllable expenses increased 12% over the prior year, the excess is recoverable.
Capital expenditure line items. Any reference to "roof replacement," "HVAC installation," "parking lot resurfacing," or "capital improvements" in an operating expense reconciliation is a red flag. These are generally not recoverable as operating expenses unless the lease explicitly provides for amortization.
Insurance billed at amounts that exceed your pro-rata share of the actual premium. Request the certificate of insurance and compare the actual premium against what you are being charged.
Gross-up applied to fixed expenses. Property taxes and insurance are fixed costs. They do not scale with occupancy. Grossing them up is an overcharge.
Denominator that differs from prior years without explanation. If your pro-rata share percentage changed but your square footage did not, ask for the denominator calculation.
Line items without vendor detail. Vague descriptions like "miscellaneous repairs" or "building services" covering large dollar amounts require invoice backup before you accept them.
Charges for leasing commissions, tenant improvement work, or legal fees. These are almost universally excluded from CAM in well-drafted leases.
Missing or Late Reconciliation: Your Rights
If the reconciliation statement does not arrive by the lease-mandated deadline, you have options:
Review your lease delivery requirements. Most leases require delivery within 90 to 180 days of year-end. Some specify that if the landlord fails to deliver by the deadline, you are not obligated to pay any true-up amount for that year. Others treat late delivery as a forfeiture of the landlord's right to collect a deficiency.
Send a written demand for delivery. Put your request in writing, cite the lease section requiring timely delivery, and set a specific response deadline. This creates a paper trail.
Do not stop paying estimates. Even if the reconciliation is late, continue paying your monthly CAM estimates. Withholding estimates because the reconciliation has not arrived is generally a lease default and carries significant risk.
Request an extension on your dispute window if needed. If the reconciliation arrives late and your dispute window starts from delivery date, you have a full window regardless. But if the window runs from year-end, a late delivery can unfairly compress your review time. Write to the landlord requesting an extension proportional to the delivery delay.
“CAMAudit processes reconciliation statements year-round because overcharges do not expire when reconciliation season ends. We see tenants submitting statements from three years ago that no one reviewed. The dispute window may be closed, but multi-year audits during the lookback period catch compounding errors that add up to meaningful recovery amounts.”
