When a landlord replaces a cracked parking lot section versus when they repave the entire lot, the physical activity looks similar on a work order but has very different implications for what can legally appear in your CAM reconciliation. Understanding the capital versus operating distinction is the foundation of catching a large category of franchise CAM overcharges.
The Core Distinction
Operating expenses (also called maintenance and repair expenses) preserve the existing condition of an asset. They restore something to its prior functional state without extending its useful life or adding new capability. Under both GAAP accounting and IRS cost basis rules, operating expenses are recognized in the year incurred.
Capital improvements extend the useful life of an asset, add new capability, or create a new asset. They are capitalized on the balance sheet and depreciated over their useful life — often 10 to 30 years for real property improvements.
In the context of CAM reconciliations, this distinction matters because most NNN leases exclude capital improvements from the CAM pool. If a capital project gets categorized as an operating expense and passed through to tenants, the tenants pay for an improvement they have no ownership interest in and will never benefit from after their lease ends.
Applying the Distinction to Common CAM Line Items
Parking Lots
Operating (CAM-eligible): Crack sealing and crack filling, asphalt patching (isolated sections), sealcoating, repainting parking lines, pothole repair, snow removal, sweeping.
Capital (typically excluded): Full milling and resurfacing (removing existing asphalt and laying new), complete reconstruction of the parking lot base, adding new parking areas or expanding the lot.
The gray area: A "major repair" that replaces more than roughly 25–30% of the total parking surface in a single project is often treated as capital even if it's described as "maintenance" in the work order. The percentage isn't a universal rule, but it's a common benchmark used by auditors. The relevant question is whether the work extended the useful life of the pavement or simply restored its prior condition.
How to identify it in the reconciliation: A paving or asphalt line item for more than $50,000–$100,000 in a single year (depending on lot size) warrants requesting the invoice to determine scope. Words like "overlay," "mill and fill," "full-depth reclamation," or "reconstruction" in the invoice description signal capital work.
Roofing
Operating (CAM-eligible): Patching leaks, flashing repairs, drain cleaning, membrane inspection and sealing, individual shingle or tile replacement.
Capital (typically excluded): Full roof replacement, installation of a new membrane system over the entire roof area, adding skylights or new roof penetrations.
The gray area: Replacing 40% or more of a roof surface in a single project is generally capital. A landlord can sometimes argue a "major repair" is still maintenance, but the invoiced cost and scope description will usually make the classification clear.
HVAC Systems
Operating (CAM-eligible in common areas): Filter replacement, belt replacement, refrigerant recharge, coil cleaning, routine preventive maintenance contracts, control board repair.
Capital (typically excluded): Full HVAC unit replacement, installation of new refrigeration systems, adding HVAC capacity to previously unconditioned spaces.
Important nuance: HVAC maintenance for common area systems (lobby, corridor, restroom ventilation) is legitimate CAM. Maintenance for in-suite systems serving only your space is your own cost. When a reconciliation includes an HVAC charge, verify whether it's for common area equipment or tenant-suite equipment.
Lighting
Operating (CAM-eligible): Lamp replacement, ballast replacement, photocell repair, fixture cleaning, routine electrical maintenance on existing circuits.
Capital (typically excluded): Installing an entirely new lighting system, converting from fluorescent to LED when it involves full fixture replacement (rather than lamp-only retrofit), adding new exterior lighting poles and foundations.
The gray zone: An LED conversion that swaps only bulbs is operating. An LED conversion that replaces entire fixture assemblies and may require new wiring is more likely capital. Review the invoice for line items distinguishing fixtures from lamps.
What the Lease Exclusion Language Says
Your NNN lease contains a list of excluded expenses — costs the landlord cannot pass through as CAM. Look for language like:
- "Capital improvements, capital repairs, or capital replacements"
- "Costs properly capitalized under generally accepted accounting principles (GAAP)"
- "Costs for which the useful life exceeds [X] years"
- "Depreciation of capital improvements"
- "Costs for original construction of the building or initial tenant improvements"
Some leases narrow the exclusion with a carve-back: "except capital expenditures made primarily to reduce Operating Expenses, which shall be included in CAM as amortized over their useful life." If your lease has this carve-back, the landlord can pass through amortized energy-efficiency capital costs, but only at the amortized amount, not the full project cost in a single year.
How to Check a Specific Line Item
Step 1: Identify the line item and its dollar amount. Large single-year amounts in maintenance-category lines are the priority.
Step 2: Request the invoice. The invoice description will typically reveal the scope — "crack seal and seal coat" (operating) versus "mill existing surface and install 2-inch overlay" (capital).
Step 3: Match the invoice description to your lease's excluded expenses definition. If the work falls within the exclusion language, it's not eligible for CAM pass-through.
Step 4: If the lease allows amortized capital pass-through for efficiency improvements, verify that the reconciliation used the amortized amount rather than the full project cost.

Frequently Asked Questions
Who decides whether a project is capital or operating — the landlord or me?
The primary standard is your lease's excluded expenses definition, interpreted against the actual scope of work as documented by invoices. If the two of you disagree about classification, the dispute ultimately traces to lease language and the documented facts. An auditor or attorney can opine on classification, but the lease controls.
Can a landlord depreciate a capital improvement and still pass through the depreciation as CAM?
Generally no. Depreciation of capital improvements is typically on the excluded expenses list. The exception is the energy-efficiency amortization carve-back described above — but that allows amortized project cost, not accounting depreciation.
What if the landlord split a large project into multiple years to make each year's cost look like maintenance?
This is a known pattern. If you see consistently elevated paving or roofing costs over multiple consecutive years without a clear operational explanation, compare year-over-year totals to prior periods and request invoices for each year. A rolling capital project billed as annual maintenance can be identified by invoice scope.
Does the capital vs. operating distinction apply to property taxes and insurance?
No. Property taxes and insurance are operating expenses by nature — they're recurring annual costs, not capital investments. The capital vs. operating distinction primarily applies to physical improvements and repairs.
How are capital improvements treated if the landlord amortizes them into CAM over time?
Only if your lease explicitly permits it and only for the categories allowed (typically energy-efficiency capital expenditures). The amortized amount per year should be a fraction of the total project cost divided by useful life. If you see a "capital amortization" or "cap-ex amortization" line in your reconciliation, verify: (a) that your lease permits it, (b) that the amortization period is appropriate, and (c) that the original project cost documentation is available.
Is roof replacement always excluded?
In most standard NNN franchise leases, yes — full roof replacement is listed as an excluded capital expenditure. The landlord owns the building and benefits from the replacement asset; tenants have no ownership interest in the improvement. Some leases do allow amortized roof replacement costs, so read your specific excluded expenses list.
