Capital Expenditures in CAM Charges: How Major Property Improvements Get Billed as Maintenance
A capital expenditure extends an asset's useful life or creates a new asset. Routine maintenance keeps an existing asset in its current operating condition. That distinction, rooted in IRS Treasury Regulation 1.263(a)-3 and GAAP accounting standards, determines whether a cost belongs in your CAM pool or outside it. Roof replacements, HVAC overhauls, and full parking lot resurfacing are capital, not maintenance, regardless of what the invoice label says.
When a landlord labels a roof replacement "roof maintenance" and includes it in the CAM reconciliation, the label does not change what the work actually was. Courts look past description language to the substance of what was done and how it would be classified under accepted accounting principles.
Of all the overcharge types that appear in CAM reconciliations, capital expenditures billed as maintenance are among the most consistently identified by auditors and the most frequently litigated. The problem is not hidden: the amounts are usually large and the line item descriptions are there for anyone to read. What tenants lack is the framework to classify what they see.
40% of CAM reconciliations contain at least one billing error, with capital expenditure misclassification among the most frequently identified categories (Tango Analytics, 2023)
The IRS framework: why useful life matters
The clearest line between capital and expense comes from IRS regulations, which commercial lease drafters and auditors often reference even outside of a tax context. Under Treasury Regulation 1.263(a)-3, a cost must be capitalized when it results in:
- A betterment to a unit of property (making it materially more valuable or in better condition than it was before the relevant period)
- A restoration of a unit of property (returning it to working condition after a major breakdown or replacing a major component)
- An adaptation of a unit of property to a new or different use
The "unit of property" concept is important. A commercial building's structural components, roof, HVAC system, elevators, plumbing, and electrical are typically treated as separate units of property for this analysis. When a major component of one of those systems is fully replaced, it is a restoration. Replacing a complete roofing system is not maintenance; it is capital.
IRS Revenue Procedure 2015-20 established a de minimis safe harbor allowing businesses to expense items costing $2,500 or less per item or invoice. Items above that threshold are presumptively capitalized unless they meet another exception. For the large-ticket items that appear in CAM pools, roof replacements costing $100,000 to $500,000+, HVAC overhauls costing $40,000 to $200,000, the de minimis exception does not apply.
How capital costs get into the CAM pool
Several mechanisms move capital expenditures into the operating expense pool:
Mislabeling on invoices. Contractors sometimes describe capital work as "maintenance" on invoices, either at the landlord's direction or as a default. The label on the invoice is not controlling; the nature of the work is.
Full inclusion in the pool year. The landlord incurs a $300,000 capital expenditure and includes the full amount in the CAM pool for the year it was incurred. Tenants' shares spike in that year.
Amortized inclusion. The landlord capitalizes the cost properly on its books but then amortizes annual amounts into the CAM pool. The CAM reconciliation shows "$20,000 capital improvement amortization" as a line item. This is an overcharge if the lease excludes capital expenditures; the amortized form does not transform a capital cost into an operating expense.
Bundling. The capital work appears as part of a larger maintenance contract that mixes routine maintenance with capital replacement. If the bundle is billed as a single line item, the capital component is hidden.

Published cases: what courts have found
In Kmart Corp. v. Cragmere Associates, LLC (M.D.N.C. 2008), the landlord attempted to include full parking lot replacement costs as Common Area Costs under the lease. The court analyzed whether the replacement was a capital expenditure excluded under the lease's terms and recommended summary judgment for the tenant: the replacement was capital, not maintenance, and the lease excluded capital expenditures.
The case matters not just for its outcome but for its reasoning. Courts examine what the work actually was (full replacement versus routine repair), what the lease's exclusion language says, and whether the landlord's characterization is consistent with how the same work would be classified under accepted accounting principles.
Cushman & Wakefield's lease audit guidance frames the issue directly: landlords often attempt to pass through "all capital expenses" in reconciliations, requiring tenants to scrutinize both the characterization and the lease authorization.
The three biggest categories to watch
Roof systems. Full roof replacements on commercial buildings range from $150,000 to over $500,000 depending on building size and materials. These are capital expenditures under almost any accounting or tax framework: they restore or replace a major structural component and extend its useful life by decades. Routine repairs such as patching, sealing, and localized flashing work are maintenance. The distinction between "repairing the roof" and "replacing the roof" is significant.
HVAC systems. HVAC maintenance including filter changes, coil cleaning, and belt replacements is clearly operating expense. Replacing a rooftop unit or overhauling the central plant is capital. Partial replacements of major components such as compressors and heat exchangers often fall in the capital category because they restore, rather than maintain, the system's operating condition.
Parking lots. Sealcoating, crack filling, and line repainting are maintenance. Full mill-and-overlay (removing the existing surface and laying new asphalt) is typically capital. Some courts have analyzed whether partial resurfacing qualifies as capital based on the percentage of the lot affected and the overall restoration effect.
15-20% of annual CAM overcharges can be recovered through a formal audit, with capital expenditure misclassification among the highest-value findings (Springbord Research, 2023)
Worked dollar example
The CAM reconciliation includes:
- "Parking lot resurfacing, full pavement replacement": $210,000
- "Roof system, complete tear-off and replacement": $340,000
- "HVAC rooftop unit replacement, 3 units": $87,000
Total capital costs in pool: $637,000
Your pro-rata share is 4.5%.
Your share of capital costs: $637,000 x 4.5% = $28,665
That is $28,665 in recoverable overcharges for a single year, assuming your lease excludes capital expenditures, which most standard NNN exclusion lists do.
Now add amortization: even if the landlord amortized these costs over 15 years rather than expensing them immediately, the annual amortization amounts (roughly $42,467/year total) would still generate approximately $1,911/year in overcharges under your pro-rata share, continuing for 15 years.
How to identify capital expenditures in your reconciliation
Pull the CAM general ledger with full expense descriptions, not just category totals. Look for line items using words like "replacement," "installation," "new," "renovation," "system upgrade," or "overhaul."
Flag any line item over $5,000 with a description that suggests major work rather than routine maintenance.
Request invoices for flagged items. A contractor invoice for a "rooftop HVAC replacement" is more specific than a line item labeled "HVAC maintenance."
Apply the IRS restoration test: Did the work replace a major component of a structural system? Did it return a degraded system to working condition? Did it increase the property's value beyond its pre-work condition?
Compare to the exclusions list in your lease. If the lease excludes "capital improvements," "capital expenditures," or "costs of a capital nature," and the work meets the restoration or betterment test, the item is excluded.
Check for amortized entries. A line item labeled "capital improvement amortization" or "depreciation expense" that appears year over year is a clear signal that the landlord is running capital costs through the pool annually. See Depreciation in CAM Charges for how non-cash depreciation charges create a separate overcharge category.
What documentation to request
- Invoices and work orders for any line item over $5,000 labeled as maintenance, repairs, or improvements
- Project scope documents for roof work, HVAC work, or major site work
- The landlord's depreciation schedule or capital improvement ledger (not always shared, but worth requesting; it shows how the landlord itself classifies the costs)
- Prior-year reconciliations to determine whether the same items appeared in prior years or whether a new capital project was included

Frequently asked questions
What if the lease allows "amortized capital expenditures"?
Some leases explicitly allow the landlord to amortize certain capital improvements and pass through annual amounts. If your lease allows this, check whether the specific items meet the criteria, for example, "capital improvements that reduce operating costs" or "capital improvements required by applicable law." Items that do not meet those criteria remain excluded.
How do I distinguish a repair from a capital improvement?
A repair maintains current operating condition. A capital improvement creates new value, extends useful life, or restores function after major failure. Practical tests: Did the work affect the whole system or component, or just a localized problem? Did the contractor issue a warranty for extended useful life? Does the work appear on the building's fixed asset register?
Can a landlord bill capital expenditures as "major maintenance"?
The label does not control the analysis. What matters is the nature of the work. Courts have consistently looked past label misdescription to the substance of what was done and whether it meets the definition of a capital expenditure under the applicable accounting or legal standard.
Is there a dollar threshold for capital expenditures?
The IRS de minimis safe harbor allows immediate expensing of items $2,500 or less per item or invoice (for businesses without an applicable financial statement). Above that threshold, capitalization is presumed for items meeting the betterment, restoration, or adaptation test. Large-ticket CAM items almost never qualify for the de minimis exception.
What if the capital expenditure was required by a new building code?
Code-mandated improvements are sometimes treated differently in leases that include "legally mandated costs" as a separate recoverable category. Check whether your lease has such a carve-out. If it does, code-required capital improvements may be recoverable even if ordinary capital expenditures are excluded. If the lease has no such carve-out, the exclusion applies regardless of why the work was required.
CAMAudit classifies each line item in your CAM reconciliation against the capital vs. operating expense distinction embedded in your lease's exclusion language. Large line items with descriptions suggesting major work are flagged for your review, with the IRS restoration analysis applied to determine the appropriate classification.

Frequently Asked Questions
What makes a CAM expense a capital expenditure rather than routine maintenance?
A capital expenditure extends an asset's useful life or creates a new asset. Maintenance keeps an existing asset in its current operating condition. The IRS uses a three-part test under Treasury Regulation 1.263(a)-3: a cost is capital if it results in a betterment (adds new capacity), restoration (returns a degraded system to working condition after major failure), or adaptation (converts the property to a new use). Replacing a complete roofing system or HVAC unit is restoration, and it is capital regardless of what the invoice says.
How do capital expenditures get into the CAM pool?
Several mechanisms move capital costs into the operating expense pool: mislabeling on invoices (contractors describe capital work as 'maintenance'), full inclusion in the year incurred, amortized inclusion (the landlord capitalizes correctly on its own books but runs annual depreciation through the CAM pool), and bundling (capital work appears within a larger maintenance contract as a single line item). The signal to look for is dollar amount: a $47,000 'roof repair' almost certainly involved replacing significant sections of the roof.
If my lease allows amortized capital expenditures, what should the annual charge be?
The annual CAM charge should be the total capital cost divided by the asset's useful life in years, sometimes with an interest component. For a $150,000 roof replacement with a 15-year useful life, the correct annual CAM charge is $10,000 per year. A $80,000 HVAC system with a 10-year life should appear as $8,000 per year. Charging the full cost in a single year when the lease only permits the amortized fraction is the overcharge, not the CapEx inclusion itself.
What is the dollar impact when a landlord expenses a major capital project in a single year?
The impact is highest in the year the project occurs. In the worked example in this article, parking lot resurfacing ($210,000), roof replacement ($340,000), and HVAC replacement ($87,000) together created a $637,000 capital pool inclusion. For a tenant with a 4.5% pro-rata share, that is $28,665 in overcharges for a single year, roughly 11 times what the correct amortized annual charge would be.
Does a landlord have to disclose capital expenditures in the CAM reconciliation?
Yes, if they are included in the pool. Most reconciliation statements list expense categories with amounts. Capital items disguised as 'maintenance' or 'building improvements' may not be labeled as CapEx, which is exactly why reviewing the general ledger with full expense descriptions is necessary. Large one-time amounts in categories like roofing, HVAC, or parking are the trigger for requesting vendor invoices to verify whether the work was capital or routine maintenance.
