Building Records Research NYC(Last Updated On: September 1, 2019)
In NYC Property Records can sometimes be difficult to find. There are resources available for building records research.
NYC Building Records Research
- DOB Records
- HPD Records / I Card
- Sanborn Maps
When looking into the records on an existing building the Certificate of Of Occupancy is always a good place to start. This can be found on the Department Of Buildings (DOB) website. The DOB may also have copies of approved plans and paperwork on the property. Sometimes this is on microfilm.
HPD Records / I Card
Before there were Certificates Of Occupancy there was the I card. This is an old handwritten card done by Housing Preservation and Development (HPD). The I card has notes on the building and sometimes a sketch of the layout. There will only be an I Card if the building has or had residential use.
Determining if a building is Landmarks is important and understanding its impact is as well. New York City has a lot of Landmark Properties and Landmark Districts.
The Department Of Finance (DOF) has financial and property records. These can be found on their online resource ACRIS or the Automated City Register Information System. On ACRIS you can find documents like deeds, easements, zoning exhibits, and other property related documents.
Sanborn maps are good for checking the history of a property. Sometimes the zoning code requires us to determine if a property subdivision was done before or after a certain year. The Sanborn maps can help prove that type of information.
