Welcome to NYC Permit Pulse
NYC Permit Pulse is a live visualization of New York City Department of Buildings (DOB) permit activity, overlaid onto the stunning pixel-art isometric map created by @cannoneyed at isometric.nyc. Each dot on the map represents an active building permit — color-coded by type, with brightness indicating recency.
