Step-by-step
Search DOB NOW Build
Go to a810-dobnow.nyc.gov and search by address. Under the job filings tab, look for filed plans. Some newer filings include digital plan uploads that can be viewed online.
Visit the DOB Borough Office
For most buildings, approved plans are stored at the DOB borough office. Visit the office in the borough where the building is located. Bring the address and Block/Lot information. Request to view the microfilm or digital plan records.
Request Through a Professional
Expeditors and architects routinely pull plans from DOB. If you cannot visit in person, hire a filing representative who can retrieve the plans on your behalf. They typically charge a fee for this service.
Check the Municipal Archives
The NYC Municipal Archives at 31 Chambers Street maintains historical building records and plans, particularly for older and architecturally significant buildings. These records may predate DOB electronic systems.
Request from Building Management
For co-ops and condos, the managing agent or building superintendent may have copies of floor plans. These are often available as part of the building offering plan or alteration agreement records.
Use RegWatch for Quick Research
RegWatch shows all DOB job filings with associated documents for any property. Quickly identify which permits have filed plans, saving multiple trips to DOB offices.
Overview
Building floor plans in NYC are public records available through the Department of Buildings. These approved architectural drawings show the layout, dimensions, exits, and structural details of a building as approved by DOB.
What Floor Plans Show
Approved plans typically include: floor layouts with room dimensions, exit paths and egress requirements, structural elements (beams, columns, load-bearing walls), plumbing and electrical layouts, fire protection systems, and zoning compliance details (setbacks, height, coverage).
When You Need Floor Plans
Floor plans are needed for renovation planning, legal disputes (verifying original layout), insurance claims, co-op and condo board approvals, and construction due diligence. Comparing current conditions to approved plans can reveal unauthorized alterations.
