MasterFormat licensing fee hike sparks outrage among architects
The Construction Specifications Institute (CSI) has revised its licensing fees for the MasterFormat system, transitioning from a semi-annual purchase model to an annual subscription based on the income of firms. This announcement, made in early February and addressed during the Master Specifiers Retreat held in Colorado Springs from February 11 to 13, has taken architects, contractors, and engineers in the U.S. and Canada by surprise. While updates previously cost less than $200, mid-sized firms now face an initial fee of $699 per year, which could escalate to thousands. Critics point to CSI's majority share acquisition by CIN, under Chris Anderson's leadership, as indicative of trends similar to Adobe's subscription approach. Architects Amy Baker and David Stutzman are mobilizing to contest this decision and seek greater transparency.
