Built for New Yorkers
StreetSmart is a free service to help NYC renters make informed decisions. We are not monetized — no ads, no premium tiers. NYC housing data was scattered across dozens of city databases or buried behind bureaucracy. We filed Freedom of Information requests, pulled in public records, and combined all 12 datasets into one free, searchable tool. Now you can actually know what you're getting into before you sign a lease or buy into a building.
