Another useful City resource for Owners and Architects are the Tax Photographs available from the NYC Municipal Archives. Between 1939 and 1941, and again in the mid-1980s, the city photographed every house and building in the five boroughs. These photos are now available for purchase from NYC.
To obtain a copy, you can go to the Archives in person (31 Chambers Street, NY, NY-check their web site for hours and details before going), or you can order a copy online.
Here's a link to the web page, which explains more about the history of the photos and has instructions for ordering online: NYC.GOV/RECORDS
The Tax Photo might be useful for permitting purposes:
This resource may be helpful to illustrate an existing non-compliance to remain to a DOB Plan Examiner, such as a projecting stoop that may require reconstruction.

What is a Revocable Consent?
A: When a Building Owner wishes to construct a portion of their building beyond the Front Lot Line or Street Line, they may be required to obtain a Revocable Consent approval to do so.
The Building Code allows certain, limited projections beyond the Street Line, for both above-ground and below-ground projections. These are covered in 1968 Building Code Subchapter4, Articles 8 & 9. See my entry on Projecting Balconies as an example of a permissible projection not requiring a Revocable Consent.
If, however, the Building Owner wishes to construct beyond the limitations specified in the Building Code, they will need to apply for a Revocable Consent through the NYC-Department of Transportation.
A Revocable Consent is a grant by the City to construct and maintain certain structures on, over, or under City Property (usually the Sidewalk or Street). As the name implies, the City may revoke the grant at any time, and thus oblige the Owner to remove the projection.
The Revocable Consent process takes approximately 4-6 months, longer if a Uniform Land Use Review Procedure is required (ULURP). The ULURP Process adds at least 6 months to the process.
Generally, consents are granted for a term of ten years, at the end of which time they may be renewed. Revocable Consents are distributed to several reviewing agencies, all of which must approve the petition:
-Borough President's Office
-DOT Borough Commissioner
-Department of Environmental Protection
-Department of Buildings
-Art Commission
-Local Community Board
-City Council
-Department of City Planning (for ULURP)
A few examples of structures that commonly require Revocable Cosents:
-A Building Cornice projecting more than 10" beyond the Property Line.
-An Outdoor Bench on the Sidewalk
-An Information Kiosk
-Building Steps or Entrance Details which project more than 18" beyond the Property Line
-Exterior Wheelchair Ramps installed on an existing building which project more than 44" beyond the Property Line.
-Canopies, exceeding the size limitations of a standard Canopy.

Projecting Balconies
Richard Meier's New Building on Prospect Park showing a nice use of Projecting Balconines beyond the Street Line
A: As per the NYC 1968 Building Code, Balconies, including their railings and supporting brackets, may project up to 22 inches beyond the STREET LINE. There are also many Zoning Regulations to consider for Balconies. In most cases, Balconies must be located at or higher than the floor level of the third story of a Building or at least 20 feet above CURB LEVEL. The aggregate length of Balconies cannot exceed 50% of the length of the Building Wall from which they project.
Check the Zoning Regulations for additional Balcony requirements.

Marquees and Canopies
An example of a Canopy, with posts that support the end of the Canopy on the Sidewalk

A: Marquees are fully supported from the building alone. A Canopy has posts that come down onto the sidewalk as additional support. Canopies require DOT Approval. Marquees may be approved by the DOB as a Permissible Projection if they comply.

Do Flags and Banners Require Work Permits?
Q: Is DOB Approval required to hang a banner or a flag on an existing or new flagpole? How are flags and banners treated?
A: A flag or banner is a Sign, and requires a DOB Sign application and compliance with the non-illuminated sign provisions of Zoning. If both sides of the flag are identical, then the area does not need to be counted twice. If a new Flagpole is proposed, this shall be filed under a separate application from the Sign, with structural connection details. Flagpoles may project across the front property line up to 2' within the curb, and shall be a minimum of 15' above the street level. Flags on Community Facility buldings which represent such facility are permitted without area limitation.
