Capital vs. Operating Costs in CAM: How to Tell the Difference
The reconciliation arrived for a law firm tenant in a 12-story office building. The CAM pool came in at $2.4 million for the year. The firm's pro-rata share was 3.1 percent, or $74,400. Pro-rata share is the tenant's slice of building costs. The estimates collected during the year covered $58,000. So the bill was for $16,400. For more context, see CAM red flags accounting firms track.
One line in the detail caught the controller's eye. "Building System Upgrade, $480,000." It was 20 percent of the entire CAM pool. It was also almost certainly a capital improvement.
Then comes the question most controllers have no time to research. Should that $480,000 be in the CAM pool at all? If not, what does the law firm tenant really owe? The answer takes lease reading, accounting judgment, and the nerve to push back on a bill the landlord calls final.
This article shows you three things. How to spot capital items hiding in a CAM reconciliation. What most leases actually allow. Where the controller-to-specialist handoff belongs.
Capital Improvement (in CAM context): A cost that extends the useful life of a building system, adds capacity, or replaces a major part as a whole. Most well-drafted leases exclude capital improvements from CAM. They add to the landlord's long-term asset value, not the tenant's day-to-day occupancy. Common examples are roof replacement, parking lot resurfacing, HVAC system replacement, elevator modernization, and structural repairs.
The accounting framework
The capital-versus-operating split is not unique to CAM. It is a standard accounting question. GAAP and the IRS tangible property regulations both give guidance on it. Here is the basic framework.
Operating expenses (usually recoverable in CAM). Routine upkeep. Repairs that restore an asset to working order without adding useful life. Supplies, services, and labor to run the property. Examples: landscaping, janitorial, HVAC servicing, light bulb replacement, parking lot striping, snow removal.
Capital expenditures (usually excluded from CAM). Costs that add useful life, add capacity, or replace a unit of property. Examples: roof replacement, full HVAC system replacement, parking lot resurfacing, elevator modernization, fire suppression system replacement, exterior cladding replacement.
The IRS rules use betterment, restoration, and adaptation tests. Those are more detailed than this summary. But for CAM review, a simple test works. Did the cost replace a major system or part as a unit? Or did it just keep the existing system running another year?
Why this distinction shows up in leases
Commercial leases written in the past 25 years almost always carry a capital exclusion clause. It sits in the operating expense section. Typical language:
Operating Expenses shall not include any costs which are capitalized in accordance with generally accepted accounting principles, including without limitation any costs of structural repairs, replacement of major building systems, capital improvements, or any costs incurred in connection with the construction or addition of new improvements.
The exclusion exists because of the economics. The tenant pays CAM to use the building. The landlord owns the asset. When the landlord replaces the roof, the building is worth more. That gain goes to the landlord. The tenant gets a roof either way under the lease. Asking the tenant to fund the roof is asking them to subsidize the landlord's improvement to the asset.
Some leases carve out narrow exceptions:
- Capital items required by law (ADA, fire code, environmental compliance)
- Capital items installed to reduce operating expenses, amortized and recovered only to the extent of actual savings
- Capital items below a stated dollar threshold
Even with carve-outs, most well-drafted leases default to exclusion.
How capital items end up in the pool
Three common pathways:
The landlord's accounting treats the item as a repair. Say a property manager codes a $480,000 roof replacement as "Roof Repair" on the GL. The cost passes through to CAM by default. The lease wants the exclusion applied at the reconciliation level. But if nobody checks each line against the lease, the cost flows through.
The bill is bundled. A vendor invoice for $84,000 is labeled "HVAC Service." It really holds $62,000 to replace two rooftop units and $22,000 for routine servicing. The landlord codes the whole $84,000 to HVAC Maintenance. The bundled cost flows through. The repair part is recoverable. The replacement part is not.
The capital item is amortized wrong. Some leases allow recovery of capital items spread over their useful life. The landlord puts the full cost in CAM in the year it happened instead. That is a timing error. It moves the charge from a future year, where some recovery may have been allowed, into the current year, where the full cost is recovered improperly.
Spotting the line item
The reconciliation statement rarely labels a capital item as "capital." A useful set of pattern flags:
- Dollar amounts that are 10 percent or more of the total CAM pool concentrated in a single line item
- Vendor names that indicate construction (roofing contractor, paving contractor, mechanical contractor) rather than service (landscaper, janitorial service, HVAC service company)
- Line item descriptions like "Building Improvements," "Major Repair," "System Upgrade," or "Roof Work"
- Amounts that are dramatically larger than prior years for the same category
- One-time charges with no corresponding figure in prior year reconciliations
When any of these patterns shows up, request the invoice and vendor scope-of-work in writing. Most leases give the tenant the right to ask for this. The landlord's response tells you a lot. So does a refusal to respond.
"Capital items in CAM are the highest-dollar findings I see when running reconciliations. A single roof replacement charge can be $200,000 to $600,000 in the pool, of which the tenant''s share might be $6,000 to $30,000 depending on pro-rata. The line item is rarely hidden, it is just unchallenged. The lease excludes it, the bill includes it, and nobody pushes back because nobody opened the lease." - CAMAudit field notes after testing reconciliation samples from published audit cases
What the bookkeeper sees versus what the controller sees
The bookkeeper sees the reconciliation arrive. They code the bill to Occupancy Expense and move on. The capital item stays invisible at that level. The bookkeeper does not have the lease open or the invoice detail.
The controller works with the lease and the line-item detail. They see the pattern. Here is the right split of labor.
Bookkeeper. Receives the reconciliation. Posts large amounts to a clearing account, not straight to expense. The threshold is often $5,000 or 5 percent of annual CAM, whichever is higher. Sends the reconciliation and any detail to the controller.
Controller. Reviews the reconciliation against the lease. Checks pro-rata share, CAM cap, base year if it applies, and the exclusion list. Flags any line that looks like a capital improvement. Requests documentation from the landlord on flagged items.
Specialist. Takes the controller's review when the variance, complexity, or dollar amount is too much for in-house staff. Runs the formal review. Prepares the correction draft if findings warrant. Works with the client and tenant counsel on recovery.
The bookkeeper's job is the threshold call. Do not post a large reconciliation straight to expense without controller review. That one habit catches most capital findings. It catches them before they become payments that are hard to claw back.
When the line item is genuinely a repair
Not every large line item is capital. Some signals that the item is genuinely operating:
- The amount is consistent with prior years' reconciliations for the same category
- The vendor is a recurring service provider (landscape company, janitorial service)
- The work is described as servicing or maintaining an existing system
- The dollar amount is small relative to the value of the underlying system
A $14,000 line for "Parking Lot Maintenance" with annual seal coating and striping is operating. A $140,000 line with the same label, in a year the whole lot was resurfaced, is capital. The label is not the test. The scope of work is the test.
Where the controller-to-specialist handoff belongs
Spot the red flag. Save the document. Escalate when it moves past bookkeeping review. The capital-versus-operating question moves from controller to specialist when:
- The dollar amount of the disputed item exceeds $25,000 in the CAM pool (often translating to $750 to $5,000 of tenant exposure depending on pro-rata)
- The lease language on capital exclusions is ambiguous or has carve-outs that need interpretation
- The landlord refuses to provide supporting documentation
- Multiple years of reconciliations may have included similar items
- The client's exposure exceeds the cost of a formal CAM audit
At that point it is no longer an accounting question. It is a contract compliance and lease review. That is what specialist CAM audit services do. The controller's job is to spot the boundary. Route the file before spending more time on work the specialist will redo anyway.
