Lately, we've had many questions in the Journalism Library about finding building histories, owner names, code violations, market value, and similar things. Here's a round-up of the most useful tools to find that information! (Photo below is a 1902 panorama of NYC from the Library of Congress.)
Dept. of Buildings: BIS (Building Information System)
Lists actions, complaints, violations, alterations, certificates of occupancy, # buildings on lot, tax block/lot # (which you need for ACRIS, listed below), landmark status, zoning documents, etc. (Under “actions,” “NB” records are permits for new buildings.) When multiple buildings are on one lot, click on the number of buildings to access building-specific records. You can also use the BIS's "Building on my Block" to find properties in a block (or community district) that are new buildings or have had alterations. Good for getting a feel for what’s going on with property development in a given area.

ACRIS (Automated City Register Information System; NYC Finance: Property) http://a836-acris.nyc.gov/CP/
Find mortgages, deeds, and other property documents. “Det” provides detailed information about the document (including the names and address of involved parties); “img” shows the document. Related NYC Property tools include the FY 2014 Final Assessment Roll for NYC and the Comparable Values for Condos & Coops.
