The Building Owners and Managers Association measurement standard for US office.

Full definition

BOMA standards (most recently the 2017 ANSI/BOMA Office Standard) define how rentable and usable square feet are measured. Different BOMA standards (1996, 2010, 2017) yield materially different numbers — always confirm which standard a quoted measurement uses.

Why this matters for Class A leasing

BOMA standard is part of the measurement vocabulary that institutional Class A occupiers, landlords, and advisers use across US markets. Understanding it correctly affects how you read lease documents, model occupancy economics, and benchmark deal terms across cities. Class A Atlas tracks the US definition alongside the global standard so cross-border occupiers can translate quickly.
