IRS rules distinguish capital improvements from operating expenses. Landlords routinely violate this distinction in CAM statements. If it belongs on Schedule E as depreciation, it should not be in your CAM bill.

Find My OverchargesSee a sample report firstThe IRS distinguishes capital improvements (depreciable assets) from operating expenses (deductible in the year incurred). Your lease's CAM clause should align with this distinction. If a landlord is depreciating a cost on their tax return, they cannot also bill it to you as an annual operating expense: that is double-dipping, and it is one of the most sophisticated and consistently overlooked CAM overcharge categories.
CAM statements routinely contain capital expenditures dressed up as operating expenses. A new roof gets billed as "roof maintenance." A full HVAC replacement is categorized as "HVAC service." An elevator modernization is described as "elevator repairs." The IRS would classify all three as capital improvements. Your lease should too, if the CAM clause excludes capital expenditures, which most well-drafted commercial leases do.
I built CAMAudit's Rule 12 (Common Area Misclassification) specifically to catch this category of overcharge because it requires both knowledge of IRS capitalization standards and the ability to match those standards against what appears in a CAM reconciliation line by line.
The IRS defines the boundary between capital improvements and operating expenses in IRC Section 263 and the regulations under it. Three tests determine whether a cost must be capitalized.
The Betterment Test: A cost constitutes a betterment if it results in a material addition to the property, a material increase in the property's capacity, or otherwise improves the property's condition beyond its condition before the expenditure. A new roof with significantly better insulation value betters the property. Patching three square feet of existing roofing does not.
The Restoration Test: A cost is a restoration if it brings the property back to its ordinarily efficient operating condition after it has fallen into disrepair, if it replaces a major component of the property, or if it returns the property to its original condition and use. Replacing an entire HVAC compressor is a restoration. Recharging refrigerant is not.
The Adaptation Test: A cost adapts the property to a new or different use if the adapted use is not consistent with the taxpayer's intended ordinary use at the time of the original acquisition. Converting a surface parking area to a structured parking garage adapts the property.
| IRS Test | Characteristic | Capital or Operating? |
|---|---|---|
| Betterment | Material addition, capacity increase, condition improvement | Capital |
| Restoration | Brings to efficient operating condition, replaces major component | Capital |
| Adaptation | New or different use from original intended use | Capital |
| Routine maintenance | Recurring activities to keep property in ordinarily efficient condition | Operating |
| Small taxpayer safe harbor | Annual cost under $10,000 and under 2% of unadjusted basis | Operating |
Regulation Section 1.263(a)-3(i) provides a safe harbor for routine maintenance: work performed to keep the property in ordinarily efficient operating condition that is expected to be performed more than once in the property's useful life. Routine maintenance is deductible as a current operating expense.
Key word: routine. Replacing a major component of a system that was installed at original construction is not routine. Cleaning, lubricating, and inspecting existing components is routine.
The routine maintenance safe harbor is the specific exception landlords exploit to misclassify capital replacement projects as operating expenses. Understanding the safe harbor's actual scope is essential for detecting violations.
The following eight categories represent the most frequently misclassified items in commercial CAM statements, with detection guidance for each.
| Category | IRS Classification | Should It Be in CAM? | How to Detect | Rule |
|---|---|---|---|---|
| Patching, sealing, minor repairs | Operating | Yes, if lease allows | Compare to typical maintenance cost per sq ft | Rule 12 |
| Full or partial roof replacement | Capital | No (unless lease explicitly allows amortized capex) | Look for one-time spike in "roof" line item | Rule 12 |
A full roof replacement typically costs $6 to $14 per square foot on a commercial building. If the roof line item in your CAM reconciliation spikes to several hundred thousand dollars, you are looking at a capital project, not routine maintenance. The IRS would require capitalization and depreciation over 39 years for commercial property. Billing it to tenants as a single-year operating expense violates both IRS treatment and standard lease CAM exclusion language.
| Category | IRS Classification | Should It Be in CAM? | How to Detect | Rule |
|---|---|---|---|---|
| Filter replacement, coil cleaning, belt checks | Operating | Yes | Consistent annual cost | Rule 12 |
| Compressor, air handler, or full unit replacement | Capital | No | Large one-time amount labeled "HVAC" | Rule 12 |
HVAC component replacement is a restoration under the IRS restoration test. Replacing the air handling unit in a 200-ton commercial HVAC system is not routine maintenance: it is a major component replacement. Costs in the $20,000 to $100,000+ range for a single HVAC component should be questioned.
| Category | IRS Classification | Should It Be in CAM? | How to Detect | Rule |
|---|---|---|---|---|
| Fill-and-patch, crack sealing, line repainting | Operating | Yes | Consistent low annual cost | Rule 12 |
| Full resurfacing (mill and overlay) | Capital (often) | Contested; depends on scope | Large one-time cost, $3-$10/sq ft range | Rule 12 |
| Parking lot reconstruction | Capital | No | Major project with contractor invoices | Rule 12 |
The IRS has litigated parking lot resurfacing cases. The result is fact-specific: a mill-and-overlay that essentially rebuilds the pavement to a like-new condition is capital. Applying a thin sealant over an existing lot is maintenance. When the cost per square foot exceeds what routine sealing commands, push for invoices.
| Category | IRS Classification | Should It Be in CAM? | How to Detect | Rule |
|---|---|---|---|---|
| Routine repainting to maintain existing condition | Operating | Yes | Consistent with painting cycle costs | Rule 12 |
| Facade replacement or recladding | Capital | No | Structural or material cost at renovation scale | Rule 12 |
Repainting the exterior every 5 to 7 years is routine maintenance. Replacing the curtain wall or applying new architectural cladding is a betterment or restoration. If the "building maintenance" line item suddenly includes a six-figure charge for "exterior work," request supporting documentation.
| Category | IRS Classification | Should It Be in CAM? | How to Detect | Rule |
|---|---|---|---|---|
| Annual maintenance contract, safety inspections | Operating | Yes | Consistent contract cost | Rule 12 |
| Controller replacement, cab renovation, motor overhaul | Capital | No | Large one-time amount under "elevator" line | Rule 12 |
Elevator modernization is explicitly a capital improvement under IRS guidance. The IRS has ruled that replacing elevator motors, controllers, and cab interiors constitutes restoration of a major component. Costs of $50,000 to $300,000+ per elevator are not operating expenses.
| Category | IRS Classification | Should It Be in CAM? | How to Detect | Rule |
|---|---|---|---|---|
| Bulb replacement in existing fixtures | Operating | Yes | Low per-unit cost | Rule 12 |
| New LED fixture installation replacing existing system | Capital | No | Project-scale cost, $10-$30/fixture installed | Rule 12 |
LED retrofits that replace the entire lighting infrastructure with a new system are capital improvements. Replacing individual bulbs in existing fixtures is maintenance. A $150,000 "lighting upgrade" that converts a building from fluorescent to LED is a capital project regardless of how it appears in the CAM statement.
| Category | IRS Classification | Should It Be in CAM? | How to Detect | Rule |
|---|---|---|---|---|
| Monthly monitoring contract, routine equipment checks | Operating | Yes | Recurring subscription cost | Rule 12 |
| New system installation, camera/access control infrastructure | Capital | No | Project cost, typically $50,000-$500,000 range | Rule 12 |
Installing a new access control system, security camera network, or integrated building management system is a capital improvement. The infrastructure becomes a fixed asset. Monthly monitoring and service contracts are operating expenses. If you see a $200,000 "security" charge in your CAM reconciliation, request itemization.
| Category | IRS Classification | Should It Be in CAM? | How to Detect | Rule |
|---|---|---|---|---|
| Drain cleaning, leak repairs, fixture maintenance | Operating | Yes | Consistent low annual cost | Rule 12 |
| Full repiping of a floor or building section | Capital | No | Large project cost | Rule 12 |
| Water main or sewer line replacement | Capital | No | Infrastructure-scale cost | Rule 12 |
Replacing the main water supply line to a building is a restoration of a structural component. It is capital. Snaking a drain is maintenance. The dollar amounts make the distinction obvious in most cases.
The most serious form of capex misclassification is not simply categorizing a capital expense as operating: it is when the landlord depreciates the asset on their tax return and simultaneously bills tenants for the full cost as an operating expense.
Here is how it works:
The double dip is: tenants pay the entire capital cost immediately while the landlord claims depreciation deductions on the same asset over 39 years.
How to detect it: Request the landlord's Schedule E or depreciation schedule (Form 4562) as part of your audit rights exercise. If an expense appearing in your CAM reconciliation also appears on the depreciation schedule, you have documented double dipping. This is the most powerful evidence available in a capital misclassification dispute.
Note: landlords are not always required to provide tax returns under audit rights clauses. However, a well-drafted audit rights clause should give you access to "books and records" related to operating expenses. An accountant's representation letter confirming that no CAM-billed items appear on the depreciation schedule is a reasonable alternative request.
Some landlords attempt to launder capital expenses into CAM by amortizing them over the remaining lease term or a defined period (commonly 5 to 10 years) and billing tenants for the annual amortized amount. The theory is that spreading the cost over time makes it look more like an operating expense.
Amortizing a capital expense does not convert it to an operating expense. An elevator modernization billed at $30,000 per year for 10 years is still a $300,000 capital project. The annual amortized charge is still a capital cost, and if your lease excludes capital improvements from CAM, the amortized charge is also excludable.
Some leases explicitly permit amortization of capital improvements with a long useful life (typically defined as improvements with a useful life exceeding the lease term). If your lease contains this permission, amortized capex is billable. If your lease excludes capital improvements without qualification, amortized capex is not billable.
Read the exact language. "Capital improvements and capital expenditures are excluded from operating expenses" with no carve-out means no amortized capex in CAM. "Capital improvements may be included in operating expenses provided they are amortized over their useful life" means amortized capex is permitted.
“The most sophisticated CAM overcharge category I built CAMAudit to catch is capex misclassification. It takes both IRS knowledge and document analysis to find it reliably. Landlords know most tenants will not request depreciation schedules. CAMAudit flags capital-scale costs in operating expense line items and generates the specific documentation request list for each finding.”
CAMAudit's Rule 12 (Common Area Misclassification) analyzes each CAM line item against three criteria:
Scale detection: Line items with costs at capital-project scale (thresholds calibrated by building type and square footage) are flagged for review. A $350,000 charge in a category typically running $15,000 to $25,000 annually is anomalous.
Category classification: The rule applies a taxonomy of operating vs. capital expense categories. Items in structurally capital categories (roof replacement, HVAC system replacement, elevator modernization, parking lot reconstruction, lighting system installation, security infrastructure) are flagged regardless of how they are labeled in the reconciliation.
Year-over-year pattern analysis: A line item that spikes dramatically in one year and returns to baseline in subsequent years is likely a capital project, not a recurring operating expense. The rule checks multi-year patterns for single-year spikes consistent with capital project billing.
Each flagged item generates a specific finding with the dollar amount, the category, the IRS classification rationale, and a recommended documentation request.
When CAMAudit or your own analysis identifies a potential capital misclassification, these are the documents to request under your lease's audit rights provision:
IRS Form 4562 (Depreciation and Amortization): This is the most direct evidence of double dipping. Any expense that appears in your CAM reconciliation AND on the landlord's depreciation schedule is a provable double-dip.
Capital improvement log: Most commercial property owners maintain a capital improvement register tracking all capital projects by property, year, cost, and depreciation schedule. Request this log for the audit period.
Project invoices and contractor agreements: For any line item that appears at capital-project scale, request the underlying invoices. The invoices will show whether the work was a full system replacement (capital) or routine maintenance (operating).
Prior year CAM reconciliations: Capital projects often disappear after one year. If a line item appears at a high value in one year only and is absent from surrounding years, it is consistent with a capital project billing pattern.
Landlord's operating expense policy: Some landlords have written policies defining which expenses they capitalize vs. expense for accounting purposes. If such a policy exists, it is discoverable under audit rights.
