This course will combine an overview of the commercial portion of the 2020 ECCCNYS with a review of COMcheckTM software. This three-hour course will cover the changes in the 2020 code relative to the previous 2016 ECCCNYS as well as provisions of the 2016 Code that have been frequently misunderstood. This will serve to refresh understanding of the current code and familiarize attendees with what is “new.”
