Changes to Chapter 17 in the NYC Building Code
Going into effect on November 7, 2022, there will be several changes to Chapter 17 in the NYC Building Code. Some of these changes include new section numbers for existing inspections, new inspection types, and additional parameters to inspection types that were already included in the 2014 Code. The Chapter name will be changed from “Structural Tests and Special Inspections” to “Special Inspections and Tests”. The section number in Chapter 17 regarding special inspections will also be changed from section 1704 to 1705. This changes all references to the code on the Technical Reports.
The major changes between the 2014 and 2022 Building Code Chapter 17 are listed below:
