SafeMap NYC is a free public tool. It reads the NYC Department of Buildings (DOB) records published on NYC Open Data and explains them in plain English. Every time you open the map or a site, the information is pulled fresh from the City. DOB refreshes its published records daily.
Sites with major work permits from the last 6 months: foundation, excavation, structural work and demolition. You can search any other NYC address to see its record too.
DOB NOW: Build permits and job filings, OATH/ECB violations, DOB violations, DOB NOW: Safety violations and DOB complaints (NYC Open Data), plus the City's address search (NYC Planning GeoSearch).
SafeMap NYC is not affiliated with the City of New York. Records can lag behind what is happening on site, and a red marker is not proof that a site is unsafe. For the official record use the DOB links on each site page. If you see an unsafe condition, call 311. In an emergency, call 911.
