Building Code and Construction Type History

Prior to the creation and adoption of the Uniform Statewide Building Code (USBC), many old building records and plans reference construction type classifications as shown in legacy building code books such as the Building Officials and Code Administrators (BOCA). This construction type history chart shows the progression of how buildings were classified throughout the evolution of the building codes. The chart helps to correlate those old construction type classification references to those used currently in our newly adopted building codes.
