Overview

Subdivision plats in New York City must align with the Zoning Resolution and local mapping requirements administered by city agencies. In Brooklyn the key offices involved are the Department of City Planning (DCP) for land-use review, the Department of Buildings (DOB) for construction implications, and the City Register (Department of Finance) for map recording. Applicants should start by confirming zoning compliance and lot configuration before preparing a certified plat for submission and recording.

Start early: zoning checks and map preparation take time.

Process & Practical Steps

Typical procedural steps for creating a new lot in Brooklyn include confirming zoning and lot area, preparing a stamped survey and plat, submitting for applicable city reviews, securing any variances or consents required, and recording the final map with the City Register. Timeframes vary by complexity and agency workload.

  • Confirm zoning district and lot-area requirements with DCP and local zoning maps.
  • Prepare a survey and certified subdivision plat by a licensed surveyor or engineer.
  • If construction or alterations are planned, obtain DOB approvals for any new or altered buildings.
  • Determine recording fees and any agency application fees before filing.
  • Submit the final plat and supporting documents to the City Register for recording.
