Carroll Gardens, Cobble Hill, Gowanus & Red Hook

This area in northwestern Brooklyn (Community District 6) combines four neighborhoods: Cobble Hill, Carroll Gardens, the Gowanus Canal corridor, and the Red Hook peninsula on Upper New York Bay. About 87% of residential lots hold one to five units and 90% date from before 1940, but large complexes also matter: NYCHA's Red Hook East and West, Gowanus and Wyckoff Gardens Houses are here. The F and G trains stop at Carroll Street, Smith–9th Streets and 4th Avenue–9th Street, and the R runs along Fourth Avenue on the eastern edge. The Gowanus Canal is an EPA Superfund site, and Red Hook Recreation Area covers 58.5 acres.

Carroll Gardens, Cobble Hill, Gowanus & Red Hook has 25,143 open HPD housing violations, 2,985 of them Class C (immediately hazardous). Inspectors issued 5,509 new violations here in the last 12 months. That's the 20th most open violations of 53 neighborhoods in Brooklyn.

“Open” counts every HPD violation not yet recorded as corrected, including old ones owners never certified, so totals can exceed the number of apartments.
