I was recently asked by a blog reader to shed some insight on a particular building in Manhattan. While I'm happy to do that (and I may include my findings in a future post), it got me thinking that now would be a good time to tell all of you about some of my favorite sites for researching properties. I've limited the list to sites you can access without a paying a usage fee. So, without further ado, here it goes:

The Oasis Map - http://oasisnyc.com/oasismap.htm - This site provides a wealth of information for free to the public. Just type in an address and you'll get info. on zoning, subway stops, block, lot, parks and other great stuff.

PropertyShark - http://www.propertyshark.com/ - Some of the same info. of Oasis, but also includes recent sales price, an approximation of its value, title history, code violations, permits, photographs, maps, etc. Basic use of PropertyShark is free, but to dig a little deeper you'll need a paid membership.

ACRIS - http://www.nyc.gov/html/dof/html/jump/acris.shtml - Standing for Automated City Register Information System, this is the official NYC online building register. Using this system you can lookup any legal document on record with the city for a given building dating back to 1966. Not only can you get the details for the document, but you can even print out a scanned original.

New York City Map Portal - http://gis.nyc.gov/doitt/mp/address.htm - This site is a good supplement to Oasis and PropertyShark for property mapping.

New York: A City of Neighborhoods - http://www.nyc.gov/html/dcp/html/neighbor/neigh.shtml - A complete electronic neighborhood map with boundaries for all NYC neighborhoods as defined by the city.

NYCProperty - http://nycserv.nyc.gov/nycproperty/nynav/jsp/selectbbl.jsp - Find out the tax assesment for any NYC property.

PlanNYC - http://www.plannyc.com/ - This site is a fantastic one stop shop for everything you want to know about NYC major urban planning projects.

Here are a few more that I use infrequently:

NYC Department of Buildings: Building Information System - http://a810-bisweb.nyc.gov/bisweb/bsqpm01.jsp

NYC Buildings Research Guide - http://www.columbia.edu/cu/lweb/indiv/avery/nycbuild.html

Streat Easy - http://www.streeteasy.com/

NYC Architecture - http://www.nyc-architecture.com/

Forgotten NY - http://www.forgotten-ny.com/ - If you're into NYC history, this site is incredible.

Happy clicking!
