Applicability of Code and Zoning

An existing building façade renovation project could be filed under either the 2014 NYC Construction Codes (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 AC 28-101.2.

However, there are exceptions regarding the use of Prior Codes, per AC 28-101.4.3. For example, the 2014 Code must be used for some 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. Renovation work must also comply with the current NYC Energy Conservation Code and other applicable local laws.

Article AC 28-302 outlines maintenance of exterior walls, including inspections, submission of reports, and repairs for existing buildings greater than six stories.

When required by the project scope of work, the facade renovation project 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.

Guidelines for Submission of Sign Project Plans

Prior to preparing the design drawings and construction documents, 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 code compliance. Based on 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 Article AC 28-104 or 2014 BC 107.2.

The Department’s guidelines outlined in section IV, item C, provides an organized approach for the preparation of construction documents; this will facilitate the plan review process. Drawings shall clearly indicate existing conditions, proposed conditions and any areas affected by the scope of work.

Complete Submission of Construction Documents

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. It is necessary for drawings to convey essential information such as plans, elevations, schedules and details. The applicable Building Codes and notes should be stated on the drawings as required to demonstrate Code and zoning compliance. It is essential to include the scale to clarify overall layouts and details on all drawings.

Title Sheet. Should clearly describe the project location, including the adjacent streets, properties, zoning district location, all adjacent zoning districts (or a detail of the current and relevant Zoning District map), and include an accompanying a graphical scale. Drawing notes should include building occupancy classification, zoning use group, flood zone statement, construction classification, the project’s scope, the building’s primary structural system, legend, etc.

Drawing Index. Clearly identify all the information that may be involved by providing a list of drawings.

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, adjacent buildings, curb cuts, north arrow, etc. The area of proposed work shall be clearly identified.

Façade Elevations. Each façade elevation must include accurate information of work involved with facade renovation including quantity, location, material, etc. Each facade elevation must correlate with a key plan and legend provided on the same sheet.

Detail Drawings. These drawings contain significant information required to clearly communicate the scope of work, in a magnified form.

Facade and parapet walls with details

Lot Line window replacement or new openings in accordance with Code requirements, interior elevations and details

Energy Analysis. An energy analysis is required for various facade projects. As dictated by the scope of work, energy analysis shall be in the form of a tabular analysis; RESCHECK or COMCHECK as required by the NYCECC and, if applicable, include the following:

Fenestration

U factors

R-value

Air sealing

If applicable, additional elements required:

Accessibility for persons with physical disabilities to comply with BC Chapter 11

Tenant/Occupant Protection Plan, only if applicable

Metropolitan Transit Authority (MTA) approval

NYC Department of Transportation (DOT) approval

NYC Landmark Preservation Commission (LPC) approval

NYC Public Design Commission (PDC) approval for exterior work only on NYC-owned properties

Post Approval Amendments. Any changes to approved scope of work that are significant and substantive will require submission of revised documents and/or plans for post-approval amendment (PAA). Any additional/new type of work not in original filing must be included via PAA. Approval for an amendment must be obtained before the work is completed. Changes in quantity of originally approved work type do not require a PAA; however these changes must be shown on plans and included in the ‘As Built’ submission (AC §28-104.3).

Expand scope of work to include additional area or elements not shown on approved plans. For example, expanding facade repair/renovation from the front of the building to the sides of the building, or addition of new facade elements, such as lintel or parapet wall

A modification to the sign mounting height, projection, orientation, and/or location

Structural changes

Changes to scope of work that require additional Special or Progress Inspection(s).

Substantive changes that meet the following criteria should be submitted for review as a PAA to amend the approved plans:

As-Built Submission. All changes must be submitted in an ‘as-built’ drawing at the end of the project.
