Approximate budget share: 0% of total CAM pool.
Capital improvements are expenditures that extend the useful life of the property, add new functionality, or restore an asset to substantially better than its original condition. Under GAAP and IRS UNICAP rules, a cost is capital if it betters the property, restores it after deterioration, or adapts it to a new use. Unlike operating expenses, capital improvements are not consumed in a single year. They produce economic benefit over multiple years and must be depreciated accordingly. In commercial leases, capital improvements should almost never appear as a lump-sum CAM line item. The industry standard is that capital expenditures are a landlord obligation, period. Some leases carve out an exception allowing the landlord to amortize certain capital improvements into CAM, typically those required by law or those that produce documented operating savings. Even in those leases, the annual CAM charge may include only the amortized fraction calculated over the improvement's full GAAP useful life, not the entire cost in year one. The most common violation is expensing a parking lot resurfacing, roof replacement, or HVAC equipment replacement as a single-year operating charge. This artificially inflates CAM in the year of the project and shifts the full landlord capital obligation to tenants.
Overcharge Risk
$5,000-$30,000/year
typical annual overcharge when this line item is disputed
Landlords pass 100% of capital improvement costs through CAM in a single year - parking lot resurfacing, roof replacement, HVAC equipment replacement - without amortization over the asset's useful life.
This line item is commonly used to disguise capital expenditures as operating expenses. Capital expenditures must be excluded from CAM or amortized over their useful life per GAAP. If you see unusually high or one-time charges in this category, request all invoices and scope-of-work documentation before paying.
| Legitimate Charge | Suspicious Charge |
|---|---|
| Annual amortization of a permitted capital improvement calculated over its GAAP useful life | Full parking lot resurfacing or HVAC system replacement billed as a lump-sum CAM expense in one year |
| Capital work required by law amortized over the compliance asset's useful life | Any capital line item on a reconciliation with no amortization schedule attached |
| Operating savings from a capital improvement documented and shared with tenants | Energy upgrade billed as CapEx pass-through with no savings documentation or offset credit |
| Interest on unamortized balance capped at the lease-negotiated maximum rate | Interest charges above market rates applied to the unamortized CapEx balance |
Absolutely exclude all CapEx from CAM unless your lease specifically permits amortization. Where amortization is permitted, require GAAP-compliant useful life periods and a cap on the interest rate applied to the amortized balance. No capital improvement may be expensed in full in the year incurred.
