The Zoning Tax Lot Database contains all tax lots from the specified version of the Department of Finance’s Digital Tax Map. For each tax lot, it specifies the applicable zoning district(s), commercial overlay(s), special purpose district(s), and other zoning related information. DCP assigns a zoning feature (includes zoning districts, special districts, and limited height districts) to a tax lot if 10% or more of the tax lot is covered by the zoning feature. For commercial overlays, a tax lot is assigned a value if 10% or more of the tax lot is covered by the commercial overlay and/or 50% or more of the commercial overlay feature is within the tax lot. The zoning features are taken from the Department of City Planning NYC GIS Zoning Features.
Up to four zoning districts are reported for each tax lot intersected by zoning boundary lines, and the order in which zoning districts are assigned is based on how much of the tax lot is covered by each zoning district.
For example: If tax lot 98 is divided by zoning boundary lines into four sections - Part A, Part B, Part C and Part D. Part A represents the largest portion of the lot, Part B is the second largest portion of the lot, Part C represents the third largest portion of the lot and Part D covers the smallest portion of the tax then ZONING DISTRICT 4 will contain the zoning associated with Part D.
