Base year

The reference year used to determine which operating expense increases a tenant is responsible for under certain commercial leases.

A base year is the reference year used to determine which operating expense increases a tenant is responsible for under certain commercial leases. The landlord typically pays expenses up to the base-year amount, while the tenant pays its share of increases above that baseline.

Why it matters

Accurate reconciliation requires teams to confirm:

  • The correct base year.
  • Which expenses belong in the base.
  • Whether the base must be adjusted.
  • Gross-up requirements.
  • Expense exclusions.
  • The tenant's pro rata share.

How REAL helps

REAL compares lease language, historical expense data and current landlord statements to validate base-year calculations.
