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 28-101.4. It is the responsibility of the Registered Design Professional to date the building to determine the applicable Codes and identify what is required to make the structure stable.
Flood Plains, BC Appendix G, must be considered when performing renovation work associated with soil and foundations, and placement of retaining walls.
However, there are exceptions if Prior Codes are used, per AC 28-101.4.3. For example, the 2014 Code must be used for safety during construction operations, Special and Progress Inspections, encroachments into the public right-of-way, and some aspects of structural work.
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.

NOTE: New applications for buildings erected under the 2008 Code must comply with the 2014 Code, as required by AC §28-101.4 and §28-102.4.3. Your building may be governed by a Code prior to 1938 based on the Code at the time it was built.
Other Regulation(s) for Reference
TPPN
Local Laws
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 Transportation (DOT), NYC Landmarks Commission, NYC Transit (MTA), Department of Environmental Protection (DEP), NYS Department of Environmental Conservation (DEC), various utility companies, and others.
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 the project will be code and zoning compliant. Based upon the complexity and scale of the project, the information provided on the drawings must clearly demonstrate all of the work required for completion of the project per 2014 AC Article 104 or 2014 BC 107.2. For underpinning and other support of excavation structures (shoring, retaining walls, etc.) provide a pre-construction report per BC 1814.1, and provide monitoring program to ensure structural stability of existing adjacent structures per BC 1814.3.
Pursuant to AC 28-101.2, the intent of the Construction Codes is to provide reasonable minimum requirements and standards, based upon current scientific and engineering knowledge, experience and techniques, and the utilization of modern machinery, equipment, materials, and forms and methods of construction, for the regulation of building construction in the city of New York in the interest of public safety, health, welfare and the environment, and with due regard for building construction and maintenance costs.
The DOB guidelines outlined in the following section IV, item C, provide an organized approach for the preparation of construction documents; this will facilitate the plan review process. Drawings shall clearly indicate existing condition, proposed condition and any area affected by the scope of work.
Construction drawings should represent complete work, including multiple disciplines such as architectural, structural, plumbing, electrical, mechanical, and others. There must be close coordination between all disciplines for the proposed scope of work to ensure Code compliance; reference AC 28-104.7 and BC 107.2 and Plan Examination Guidelines – Minimum Requirement for Review of Design Drawings, Revised 4-30-2014.
A complete submission of drawings should include:
Construction Documents. Drawings necessary to convey essential information such as sign copy, sign size, structural support or mounting system, elevations, and details. The entire scope of work must be clearly outlined on the drawings submitted. The applicable Zoning Resolution (ZR) and Building Code (BC) sections, text or notes should be stated on the drawings as required to demonstrate compliance. A scale should be included on the drawings; a graphic scale is recommended.
If applicable, additional elements required on drawings include:
When submitting the construction documents to the Department, the Registered Design Professional, Applicant of Record, is responsible for submission of complete set at filing: application, drawings, and coordination of required documents as summarized below.
1. Drawings. The renovation project drawings should reflect clear scope of work and include all affected systems. Examples of this are as follows:
Designator - Sheet Number: Sheet Description T-001.00 Title Sheet, Site Plan, Drawing Index, General Notes, required special/progress inspections list, and Legends Z-101.00 Zoning Analysis and information A-100.00 Architectural Plans and Details B-101.00 Borings and/or Geotechnical Tests and Results FO-101.00 Proposed Foundation Plans and Details S-101.00 Structural Plans and Details SG-101.00 Sign Plans, Elevations and Details of Supporting Structures SOE-101.00 Support of Excavation - Excavation, Fill, Underpinning, Sheeting, Shoring, Bracing, retaining structures, construction monitoring plan, construction notes, Piling Plans and associated details SSP-101.00 Site Safety Plan EN-100.00 Energy Code Analysis and Notes Drawing Legend to include: Symbols, abbreviations, notes and definitions.
Recommended Drawing Designators

A: Architectural: Mandatory designation for drawings showing architectural work.
B: Borings/Geotechnical: Includes subsurface investigations and soil tests.
FO: Foundation: Mandatory designation for drawings whenever foundation work is filed.
S: Structural: Mandatory designation for drawings whenever structural work is filed.
SG: Sign: Mandatory designation for drawings when work is filed separately for a sign permit.
SOE: Support of Excavation: Mandatory designation when filing construction documents with support of adjoining properties & structures during construction. Includes: excavation, fill, underpinning, sheeting, shoring, bracing, piling, etc.

2. Required Documents. Based on the building location, designation, and the project scope of work, the following submissions may have to accompany the drawings at intake:
3. Post Approval Amendments. Any changes to approved scope of work that is significant and substantive will require submission of revised document and /or plans for post approval amendment (PAA). Approval for an amendment must be obtained before the work is completed. Changes that are not substantive do not require a PAA; however these changes must be shown on plans and included in the ‘as built’ submission at the end of the project (AC 28-104.3)
Substantive changes that meet the following criteria should be submitted for review to amend the approved plans:
4. As-Built Submission. All changes must be submitted in an ‘As-Built’ drawing at the end of the project. Any changes affecting the energy analysis will require an update to the energy analysis.
As per BC Chapter 17, renovation work may require certain Special and Progress Inspections to be performed during and at the end of construction as outlined in the table below. Prior to Approval, the Applicant of Record is required to identify all required Special and Progress Inspections (BC 1704.1). Prior to DOB permit issuance, the Owner must typically engage a registered Special Inspection Agency (SIA) who will take responsibility for the Special and Progress Inspections. The Applicant of Record may perform these inspections if they are also an SIA. Inspection discrepancies and hazardous conditions must be reported to the super-intendent of construction, as well as to the Site Safety Coordinator or Site Safety Manager, for correction, per BB 2016-006 and 1 RCNY 101-06. Per BC 1704.1.2, the Contractor cannot hire the Special Inspector.
