The photographs used for the property cards comprise two additional collections. The collection number for the property cards collection is REC 0048.


The collection includes cards for all five Boroughs and totals 1,448 cubic feet. Attached to each card is a small photographic print of the building façade. The information recorded on the card includes a plot diagram indicating where the property is located within the block a building diagram outlining the dimensions of the building on the property block and lot numbers zoning code and building classification information the assessed valuation (beginning about 1930 and updated annually through the 1970s) and conveyance and mortgage information (less consistently updated). In the 1930s, as part of an effort to improve the process of assessing property for tax purposes, city assessors recorded information about each property on a card that measures 8 ½” x 14. Unlike the block and lot records, information in the docket books pertains to buildings throughout Manhattan.

The entries are recorded chronologically. It lists the date the plan was approved, and when construction was completed. The information recorded includes the date of application, location, owner, architect, dimensions and materials, type of building (e.g., loft, factory, garage, tenement), and construction details (e.g., foundation and roof materials). They record in a chronological, ledger format basic information about every application to construct or alter a building in Manhattan. The Department of Buildings docket books span 1866-1951. They total 816 cubic feet and are arranged by block and lot number. The Department of Buildings had also microfilmed the permit application folders, but unlike the plans which were rendered inaccessible by the filming process, the permit folders survived relatively intact, and have been made accessible to researchers. They are supplementary to the plans that are the subject of this collection guide. They provide ownership information, specifications, and construction details for buildings located in blocks 1-958. The Manhattan block and lot records (REC 0010), 1866-1976, consists of forms and correspondence submitted to the Department of Buildings for proposed construction projects.
