Frequently Asked Questions About New York City Special Inspections

What Are Special Inspections

Special Inspections are conducted during the construction process to verify that work is being done in accordance to approved plans and specifications. Special Inspections have been mandatory for all construction jobs in New York City since July 1, 2008. Special Inspections must be performed by Special Inspectors on behalf of a Special Inspection Agency.
Special Inspections are inspections of selected materials, equipment, installation, fabrication, erection or placement of components and connections; these inspections confirm compliance with approved construction documents and referenced standards required by NYC Building Code Chapter 19 (elsewhere in the Building Code or its referenced standards).

What Do Special Inspectors Do?

Special inspectors and/or special inspection agencies:
(i) Examine all approved construction documents that relate to the work that is the subject of the special inspections.
(ii) Confirm that the documents are sufficient to enable the proper performance of the special inspection.
(iii) Confirm that the documents are acceptable to the registered design professional of record or another design professional retained by the owner and who prepared the documents for the construction of the job. Acceptance shall be demonstrated in writing by the design professional on the documents.
(iv) Confirm that the work that is the subject of the special inspection is in compliance with all relevant approved construction documents and with chapter 17 of the New York City Building Code or elsewhere in the construction codes or their referenced standards
