BOMA International Releases Multi-Unit Residential Measurement Standard

May 17, 2010


BOMA collaborates with Industry Groups to Develop Uniform Methodology for Measurement of Multi-Unit Residential Properties

(WASHINGTON—May 17, 2010) The Building Owners and Managers Association (BOMA) International has released Multi-Unit Residential Buildings: Standard Methods of Measurement (2010), a new measurement standard that provides a uniform methodology for computing, communicating and comparing the measurement of multi-unit residential buildings. The Standard was developed through the collaborative efforts of four leading industry associations: BOMA International, the Institute of Real Estate Management, the National Association of Home Builders and the National Multi Housing Council.

"Multi-Unit Residential Buildings: Standard Methods of Measurement (2010 ) is a key addition to the BOMA suite of space measurement standards and will help industry professionals do their jobs better because it provides an  unequivocal direct measure of the physical size of the floor area of a multi-residential building,” remarked BOMA International Chair James A. Peck, RPA, FMA, senior director of asset services, CB Richard Ellis. “We are confident this standard will meet the needs of architects, appraisers, space planners, interior designers, engineers, property owners and managers, leasing professionals, asset managers, and others associated with multi-unit residential buildings.”

The new features of the standard include:

  • Flexibility. The standard offers two measurement methods: a Gross Method, which generally measures unit gross area, and a Net Method, which generally measures unit net areas. The measurement of common areas of a building is adjusted depending on whether Method A or B is employed so that the construction gross area of the building will be the same whichever method is employed.
  • Versatility. The standard is intended for measuring individual units as well as for the aggregate area of the building. Further, it provides a method by which floor area is classified for all multi-unit residential buildings.
  • Clarity. The standard includes step-by-step procedures for calculating measurement and includes a Measurement Concepts section providing further clarification of certain defined terms.
  • Interactivity. The new standard features full color illustrations, worksheets and 36 definitions of measurement terms, hyperlinked in a PDF downloadable format.

The new standard is the latest title in BOMA’s suite of measurement standards, which also includes Office Buildings: Standard Methods of Measurement (ANSI/BOMA Z65.1-2009) Gross Areas of a Building: Standard Methods of Measurement (ANSI/BOMA Z65.3-2009), and Industrial Buildings: Standard Methods of Measurement (ANSI/BOMA Z65.2-2009). Later this year, BOMA will release a standard for measuring shopping centers.
