Applicability of Code and Zoning

An existing building alteration project could be filed under either the current codes, the 2014 NYC Construction Codes [Administrative (AC), Building (BC), Plumbing (PC), Fuel Gas (FGC) and Mechanical Codes (MC)], or under prior codes, such as the 1968 Code, 1938 Code or earlier Codes, depending on the age of the existing building; reference AC 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 some accessibility requirements, certain alteration 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. Alteration work must also comply with the 2011 NYC Electrical Code, and the current NYC Energy Conservation Code. The following Reference Guides provide instructions:

In flood plains, BC Appendix G must be considered when performing alterations. Where required by the project’s scope of work the alteration 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), NYS Department of Environmental Conservation, NYC Landmarks Commission, and others.

Policies and Procedures Notices

Department Memoranda

Guidelines for Submission of Alteration 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. 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 28-104, 2014 BC 107.2 and BC 1603.

The Department’s guidelines, outlined below, 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.

Complete Submission of Construction Drawings

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, BC 1603 and Plan Examination Guidelines – Minimum Requirement for Review if Design Drawings, Revised 3-10-2014.

A complete submission of drawings should include:

The applicable Building Codes and notes should be stated on the drawings as required to demonstrate Code and zoning compliance. Where essential to clarify overall layouts and details, a scale should be included on the drawings; a graphic scale is recommended. Provide a title block with a 3 inch x 3 inch space for DOB approval stamp

  • Title Sheet. Should clearly describe the project location, including the adjacent streets, properties, FIRMS, etc. and a graphical scale. Drawing notes should include the building name and address, names and contact information of all parties involved, occupancy classification, zoning use group, construction classification, the project’s scope, a list of related job filings/applications, a list of special and progress inspections, and the building’s primary structural system.

  • Drawing Index. A list that clearly identifies all drawings involved in the project; include drawing sheet numbers and drawing titles.

  • Site/Plot Plan. Clearly show the size and location of the lot, show all existing structures on the zoning lot, and include all dimensions and other relevant information such as streets, zoning map(s), a dimensioned plan showing all bulk requirements, existing public utilities and features, adjacent buildings, curb cuts, north arrow, etc. Clearly identify the area of proposed work.

  • Floor Plans. Show existing and proposed conditions, including layout of walls; dimensions; plumbing fixtures; gas appliances; stairs; elevators; lifts; footings and foundations; excavations; lighting plan; encroachments into the public right-of-way; roof plan; clearly identify rooms’ names and use them consistently between the different discipline drawings. Coordinate between all trades/disciplines (architectural, structural, mechanical, electrical, plumbing, sprinkler and standpipe) to ensure that the proposed scope of work is complete and shown on all submitted discipline drawings. Architectural drawings must indicate fire rating for partitions, ceiling, walls; location of penetrations through fire-rated assemblies; and doors, windows and other finishes.

  • Exterior Elevations. Required if the project involves the alteration or modification of the building’s exterior and in some cases also required for interior alterations that may impact the façade. Show any altered exterior surfaces, including openings, fenestration, floor heights, head heights, control joints, adjoining grade levels compared with NAVD, foundation lines, materials, zoning analysis cross references, chimney and vent heights and penetrations. Interior elevations may be required to demonstrate compliance with Code.
