Property Information in Brooklyn and Manhattan

For assessed and market value, zoning information and ownership of specific properties in Brooklyn neighborhoods, check out Destination Brooklyn, Brooklyn Economic Development Corporation's interactive web map. This resource also offers detailed demographic data for the surrounding neighborhood. 

Data on recently sold property in New York City is available online at ACRIS (Automated City Register Information System.  To locate the price of a property, choose "Search Property Records", then choose the search option "Document Type."  Select "Deed" and the date range you are interested in searching. Once you find the list of deeds, click on the "DET" to see the detailed record for each property. The sale price of the propery is listed in the "Doc. Amount" field.  Addresses can be converted into block/lot numbers and vice-versa via the "Find Addresses and Parcels" feature. Once you have a block/lot number, this number can be entered into the "Parcel Identifier" search option to reveal a host of relevant documents, not just deeds.

In addition to ACRIS, many NYC government agencies provide other useful information. For example, NYCProperty allows users to look up an address and quickly view block and lot information, owner's name, real estate billing address, property history, property tax payments, assessment data and water charges. Building and lot dimensions are buried within the assessment rolls. The New York City Department of Finance supplies more general information about NYC's real estate taxes.  You can check the status of building violations and complaints through the Buildings Department's Buildings Information System.

Information on recent local real estate transactions is also available in book form. In some cases, these can be easier to browse than online resources. Both residential and commercial sales may be found in Brooklyn Comps Directory. Brooklyn Comps reports single-family homes, two- to three-family homes, apartments, condominiums, etc.

Detailed Brooklyn residential property information available on microfiche from Real Estate Solutions includes the property owner's name and mailing address, the taxpayer's name and mailing address, mortgage company, block and lot numbers, sales information and a description of the building. 
 
The Standard Brooklyn Commercial Directory provides block and lot number, owner's contact information, lot and building size, and sales and assessment data.
 
The Real Estate Directory of Manhattan provides detailed information on residential buildings in four volumes, including comparable sale prices.
  
To locate information on residential cooperatives and condominiums in Brooklyn and Manhattan, use the Coop/Condo Directory of Brooklyn and the Coop/Condo Directory of Manhattan. The listings provide a physical description of the building and the names of the managing agent, the board president and the building superintendent. The owners/cooperators of individual units are not listed. 
 
Domania and PropertyShark are websites for locating information on home sale prices.  PropertyShark has extensive information on specific cities, including the five boroughs of New York City. Both sites allow you to evaluate prices, property taxes and mortgage rates.

Zoning is also critically important because it sets limits on how a property may be developed or utilized. For suggestions on how to access zoning information, visit the Zoning section of How do I find a location for my business.
