BOMA Retail Standards


In 2010, BOMA released "Retail Buildings: Standard Methods of Measurement (ANSI/BOMA Z65.5-2010)." Although the BOMA 1980 and 1996 Office Standards included provisions for retail spaces (Store Area) in office buildings, the 2010 Retail Standard is the first BOMA Standard designed specifically for dedicated or dominantly retail occupancies such as big box, shopping malls, strip plazas and outparcel tenancies.

The Retail Standard does not include gross-ups or load factors and focuses predominantly on calculating Gross Leasable Area. The Standard goes into considerable depth to define the extents of Gross Leasable Area including the building perimeter, measure line and lease line (among others). The Retail Standard also provides specific direction for typical retail building elements like mezzanines, kiosks, food courts and parking.


Use the office standard if your building contains 51% or more office occupancy. Use the retail standard if your building is 51% or more retail occupancy.
