Additions, alterations, and voluntary seismic improvements to existing buildings can be challenging to implement. This presentation provides a brief history of the addition and alteration code sections’ evolution; survey questions asked of the structural engineering community; and the results of the survey, including differentiation of responses by practicing engineers and building officials, licensed structural engineers and licensed civil engineers, younger engineers and seasoned engineers. Survey data is analyzed to correlate the questions to Existing Building Code provisions and highlights common themes of uniformity and disagreement among the profession. The presentation concludes with remarks that may help both practicing engineers and building officials by providing a path forward.
