BOMA 2018 for Gross Areas: Standard Methods of Measurement (ANSI/BOMA Z65.3—2018) is the update to the original 2009 Gross Areas Standard. The BOMA Gross Areas Standard was developed in direct response to requests for a floor measurement standard that could be applied to all building types and forms of occupancy—office, industrial, retail, multi-unit residential, mixed-use and campus-style facilities. The purpose of the Gross Areas Standard is to provide a comprehensive and consistent methodology for measuring all building types while presenting the data in various ways that are useful to the stakeholders of any given property.

Features of the 2018 Gross Areas Standard:

  • Follows the new format introduced with the 2017 Office Standard—landscape to align the standard’s language with the accompanying illustrations, step-by-step format to make it easier to follow, and rewritten to make it easier to understand the concepts and methodologies, including helpful hints.
  • Expanded Glossary of Terms, including references back to the related section.
  • Incorporates best-practice guidance developed after the publication of the 2009 standard to address ambiguities and inconsistencies in the 2009 version.
  • Compatible with the International Property Measurement Standards.
  • Replaces the terms “Exterior Gross Area (EGA)” and “Construction Gross Area (CGA)” with Gross Area 1 (Leasing Method), Gross Area 2 (International Comparison Method), Gross Area 3 (Volumetric Method) and Gross Area 4 (Construction Method).
