NYC Zoning Tax Lot Database: Parcel-Level Zoning Designations

The NYC Zoning Tax Lot Database, provided by the NYC Department of City Planning (DCP), contains up-to-date zoning designations for individual tax lots. It maps zoning districts, commercial overlays, special districts, and limited height districts to specific tax blocks and lots (BBL). The database is updated monthly to reflect rezoning actions and corrections.

Use Cases

• Identifying zoning districts for a property using Zoning District 1, Zoning District 2, and Zoning Map Number.
• Checking for commercial development allowances using Commercial Overlay 1 and Commercial Overlay 2.
• Analyzing special zoning regulations using Special District 1, Special District 2, and Special District 3.
• Verifying building height restrictions using the Limited Height District column.
• Linking zoning data to other property records using the BBL (Borough, Block, Lot) identifier.

Strengths

• Updated monthly to reflect rezoning and corrections, as stated in all source descriptions.
• Contains detailed zoning attributes, including up to four zoning districts and two commercial overlays per lot.
• Available on multiple platforms (Socrata, Data.gov), indicating established use and distribution.

Limitations

• Key metadata like row count, file size, and license are not provided on any platform.
• The 'last updated' dates conflict between sources, with one showing 2025-09-02 and others showing 2026-04-12.
• The datagov source lacks column information, reducing discoverability on that platform.
