Applicability of Code and Zoning

An existing building renovation project could be filed under either the current Codes, the 2014 NYC Construction Codes (Administrative, Building, Plumbing, Fuel Gas and Mechanical Codes), or under Prior Codes, such as the 1968 Code, 1938 Code or earlier Codes, depending on the age of the existing building; reference Administrative Code (AC) section 28-101.2.

However, there are exceptions if Prior Codes are used, per AC 28-101.4.3. For example, the 2014 Code must be used for accessibility requirements, certain renovation work of mechanical, plumbing, sprinkler, fire protection and/or fuel gas systems, specific building elements such as security grilles, handrails, guards, roofs, etc., and certain kinds of structural work.

Flood Plains, BC Appendix G, must be considered when performing renovations.

Renovation work must comply also with the current NYC Energy Conservation Code and applicable Local Laws, Rules and regulations.

When required by the project scope of work the renovation must also comply with the rules, regulations, laws and Codes of other City agencies, such as the NYC Fire Department (FDNY), NYC Environmental Protection (DEP), NYC Transportation (DOT), NYC Landmarks Commission, NYS Department of Environmental Conservation, and others.

Guidelines for Submission of Renovation Project Plans

Prior to preparing the design documents and construction drawings, the Registered Design Professional must perform a pre-design review that analyzes all of the existing building elements, systems and other components affected by the proposed scope of work, to verify a code compliant renovation of the building. Based upon the complexity and scale of the project, the information provided on the drawings must clearly describe all of the work required for the code compliant execution and completion of the project per AC Article 104 or 2014 BC 107.2.

The Department’s guidelines, outlined in the following section IV, item C, provides an organized approach for the preparation of construction documents; this will facilitate the plan review process.
