As New York City’s building stock continues to evolve, understanding how code requirements apply to existing buildings is becoming increasingly important. Expected to take effect in July 2027, the new New York City Existing Building Code (EBC) will establish a dedicated framework for work involving existing buildings.
This course provides an overview of current and historic NYC Building Codes, and new concepts and clarifications in the EBC related to alterations, additions, and changes of occupancy. It explains the technical code requirements that are triggered based on various levels of alterations, and differentiates them from the current codes in effect.
