Expense stop structures in office leases require landlords to correctly determine the base year expense level, apply per-square-foot calculations at the appropriate gross-up percentage, and enforce any exclusions or caps negotiated in the lease. When base year gross-up is applied incorrectly or per-SF pass-through calculations use the wrong denominator, tenants are systematically overbilled or underbilled for operating expense obligations — errors that persist undetected through every subsequent reconciliation cycle.
