  • Dept. of Buildings PW-1 form

An example of a vanity address would be 11 Penn Plaza, previously known as 393 7th Avenue.

    Legal Status of Streets

    The Bureau of Topography maintains and provides access to the following records related to the legal status of streets in The Bronx:

    Record Maps show the current comprehensive locations of street lines and legal grades. Blocks are located on a grid with monuments installed for survey purposes. Coordinate values for the monuments are related to a common point of origin.

    Title Maps show the city ownership or dedication to public use of mapped streets.

    Bench mark maps and data show the location of elevation bench marks for use in surveying.

    Alteration Maps are changes to the city map which when filed become part of the city map.
