The total collection of operating costs a landlord groups together before allocating shares to individual tenants. The composition of the expense pool directly determines your CAM bill, and disputes frequently center on which costs belong in the pool and which do not.
An expense pool is the aggregate of operating expenses eligible for tenant reimbursement under the lease. The pool is defined by the lease's inclusion and exclusion lists. Common structures include a single pool for all operating expenses, separate pools for controllable vs. uncontrollable expenses, and separate pools for different expense categories (maintenance, taxes, insurance). The pool total divided by the building's rentable area yields the per-square-foot rate applied to each tenant.
A landlord maintains one undifferentiated expense pool that lumps capital improvements, leasing commissions, and above-standard tenant buildouts alongside routine maintenance. Tenants pay their pro-rata share of the inflated total without visibility into what is included.
Request a line-item breakdown of the expense pool every year. Cross-reference each line item against your lease's inclusion and exclusion lists. Items that appear in the pool but are excluded by your lease are recoverable overcharges.
