For more than a century, BOMA International has set the standard for measuring buildings. In 1915, BOMA published its first office standard, Standard Method of Floor Measurement. Throughout the years, the standard has been revised to reflect the changing needs of the real estate market and the evolution of office building design. Today, BOMA International is the American National Standards Institute (ANSI) secretariat for a suite of area measurement standards.
BOMA International's Standards are available in print or digital. Digital access is available for 6-months.

International Property Management Standards (IPMS)
BOMA International is a founding member of the International Property Measurement Standards Coalition (IPMSC)—an international group of professional and not-for-profit organizations who work together to develop and implement global standards for measuring real property. Through the adoption of the IPMS, property assets will be measured in a universal and consistent way, creating a more transparent marketplace, stronger investor confidence and increased market stability.
