When your landlord sends a CAM reconciliation, it arrives as a multi-page document with columns of numbers, category labels, and a final balance that tells you whether you owe money or have a credit coming. If you've never dissected one before, it looks opaque. It isn't, once you understand the structure.
This article walks through each section of a typical NNN franchise CAM reconciliation in the order you'll encounter it, explains what each number means, and tells you which lease provision controls it.
Section 1: The Header
The first block of a reconciliation identifies the property, the tenant, and the period being reconciled.
What to read here:
- Property name and address — confirm this matches your lease. If you have multiple locations, this is where reconciliations sometimes get filed to the wrong store.
- Tenant name and suite/unit — should match the tenant entity on the lease, not the operating trade name.
- Lease year — most leases define the CAM year as January 1 through December 31, but some run on fiscal years or lease anniversary years. Verify this matches what your lease says. A reconciliation covering 13 or 11 months is a known error pattern.
- Reconciliation date — typically issued 60–120 days after year-end. Check whether your lease sets a deadline for the landlord to deliver the reconciliation, because late delivery sometimes affects your right to dispute.
Lease provision to cross-reference: Article or section defining the "Lease Year" or "Operating Year," and any provision governing the landlord's obligation to deliver a reconciliation within a specified timeframe.
Section 2: The Expense Schedule
This is the core of the document. It lists every cost the landlord incurred to operate the common areas of the property and is claiming against the tenant pool.
How it's organized:
Expense schedules are typically grouped into categories: maintenance and repairs, utilities, insurance, property management, landscaping, security, administrative, and property taxes. Within each category are individual line items (e.g., "parking lot sweeping," "exterior lighting electricity," "liability insurance premium").
What to do in this section:
Look at each line item and ask: is this a common area expense, or does it serve a specific tenant's space? Costs for corridors, restrooms, parking lots, and vestibules are legitimate CAM. Costs that serve only your suite or only the anchor tenant's space are not.
Check for capital items disguised as maintenance. A line reading "parking lot resurfacing" or "roof replacement" at a cost significantly higher than prior years may be a capital improvement that your lease excludes from CAM.
Look for management fees. They often appear as a separate category, and the percentage they represent of total CAM is worth calculating immediately.
Lease provision to cross-reference: The "Common Area Maintenance Expenses" or "Operating Expenses" definition, and the "Excluded Expenses" list, which typically occupies several subsections.
Section 3: Subtotals and Exclusions
After the line items, the reconciliation will show a gross total followed by any adjustments or exclusions the landlord has applied. This is where the landlord is supposed to back out capital expenditures, costs covered by insurance proceeds, and expenses attributable to the anchor tenant if they have a CAM exclusion.
What to watch for:
If you see a gross total and a net total with no adjustments between them, the landlord may not be applying any exclusions. That doesn't necessarily mean they're wrong, but it warrants a question: are there any capital projects or excluded items this year?
Section 4: The Pro-Rata Calculation
The pro-rata section converts the total CAM expense pool into your share.
The formula:
Your Share = Total CAM Pool × (Your RSF / Denominator RSF)
What to verify:
- Your RSF (rentable square footage): Should match the exact RSF stated in your lease, typically in the demised premises section.
- Denominator RSF: This is the total leasable area used to calculate everyone's share. Pull the definition from your lease. It is almost never simply "total building square footage." Many leases exclude anchor tenant space from the denominator when the anchor has a CAM exclusion — if the anchor is excluded from contributing to CAM, their space must also be removed from the denominator, or your share is inflated.
- Pro-rata percentage: Calculate it yourself. Divide your RSF by the denominator and compare to what the reconciliation states.
Lease provision to cross-reference: The "Pro-Rata Share" definition, and any provisions addressing how anchor tenant space is treated in the denominator.
Section 5: Estimated Payment Ledger
If your lease requires monthly CAM estimates (sometimes called "CAM advances"), this section shows what you paid throughout the year.
The ledger typically lists 12 monthly payment amounts and totals them. Verify the total matches your own payment records. Discrepancies here, while rare, do occur — especially after a lease assignment or management company change.
Lease provision to cross-reference: The section governing estimated monthly payments, sometimes labeled "CAM Estimates" or "Monthly CAM Deposits."
Section 6: The True-Up Balance
The final section subtracts your total estimated payments from your calculated share of actual CAM.
True-Up Balance = Your CAM Share (Actual) − Total Estimated Payments Made
A positive number means you owe additional money. A negative number means you have a credit.
Timing matters here: Most leases require the tenant to pay a true-up balance within 30–60 days of receiving the reconciliation. Read that deadline carefully — paying late can have consequences.
If the balance is a credit, check what the lease says about how credits are applied. Some leases apply them to the next period's estimates rather than issuing a refund.
What to Do After Reading the Reconciliation
Once you understand what each number represents, you can begin verifying them:
- Recalculate your pro-rata share using your lease RSF and the denominator definition from your lease.
- Review the expense schedule against the excluded expenses list in your lease.
- Check the management fee against the cap in your lease (typically 4–6% of controllable expenses, though it varies).
- Compare year-over-year — if total CAM increased more than 10% from the prior year, identify which line items drove it.
CAMAudit automates this verification. Upload your reconciliation and lease at /scan and the tool flags deviations from your lease terms within minutes.
Frequently Asked Questions
What does "controllable expenses" mean in a CAM reconciliation?
Controllable expenses are CAM costs the landlord can manage through operational decisions — maintenance, landscaping, security, management fees. They're distinguished from "non-controllable" costs like property taxes and insurance, which the landlord can't directly control. Many leases cap annual increases on controllable expenses but not on non-controllable ones.
Can I request documentation for line items in the reconciliation?
Yes. Most NNN leases give tenants an audit right that allows you to request supporting documentation (invoices, contracts, general ledger entries) for any line in the reconciliation. The audit right typically has a time window — 60 to 180 days from receipt of the reconciliation is common.
What if the landlord missed the deadline to deliver the reconciliation?
Review your lease. Some leases include a provision stating that if the landlord fails to deliver the reconciliation within a specified period (often 12 months after year-end), the landlord waives its right to collect additional amounts for that year. This is not universal, so you need to check your specific lease language.
Why does the denominator sometimes change year over year?
The denominator changes when the occupancy profile of the property changes — new tenants leasing space, existing tenants vacating, or an anchor's exclusion arrangement changing. If the denominator shrank (fewer square feet in the pool), your share percentage went up. Ask for the denominator documentation to confirm the change is accurate.
Is a management fee on top of property management the same thing?
Sometimes they're the same line billed under different names, and sometimes they represent genuinely different charges. An "administrative fee" and a "management fee" appearing as separate line items may be double-billing the same overhead. Cross-reference both against your lease's definition of what's included in the management fee cap.
What happens if I dispute the reconciliation but the payment deadline passes?
Pay the undisputed portion before the deadline to avoid triggering a late payment clause. Send your dispute in writing simultaneously, before the deadline, referencing the specific lease provisions you believe were violated. Keeping payment and dispute separate protects you from a landlord arguing you waived the dispute by paying in full.
