Built for New Yorkers

I'm Rory. I studied law and engineering and built StreetSmart as a hobby project to make NYC housing data actually accessible. Using FOIL requests and public records, I've compiled data that was previously scattered across dozens of city databases (or not available at all) into a free searchable tool so that you can find important information about any building before you rent or buy.
