Park Slope

Park Slope runs from Fourth Avenue up to Prospect Park West, and from Flatbush Avenue south to about 15th Street. In this NTA it also reaches north to Atlantic Avenue near Barclays Center. Brownstone and brick rowhouses fill the side streets, with six-to-eight-story apartment buildings and newer towers near Fourth and Flatbush Avenues.

The Park Slope Historic District, designated in 1973 and extended in 2012 and 2016, is the city's largest landmark district. Lines include the R on Fourth Avenue, the F and G at Seventh Avenue and Ninth Street, the 2 and 3 under Flatbush Avenue, and the B and Q at Seventh Avenue on the edge.

Fact-checked October 12, 2026

Re-checked 2026-10-12: subway stations re-tested against the 2020 NTA polygon; PLUTO home counts and shares recomputed from residential units inside the polygon and matched; park acreages from the NYC Parks Properties dataset. Boundaries are approximate. Fixed: southern edge set to about 15th Street (Prospect Expressway is in the Windsor Terrace-South Slope NTA); B/Q 7 Av station is just outside the polygon, now 'on the edge'; 'one of the largest' sharpened to largest landmark district. Confirmed: historic district 1973 with 2012 and 2016 extensions (Wikipedia and LPC coverage); Washington Park 3.03 acres and reconstructed Old Stone House (NYC Parks).

“Open” counts every HPD violation not yet recorded as corrected, including old ones owners never certified, so totals can exceed the number of apartments. Statistics: NYC Open Data (HPD violations, 311 service requests, DCP PLUTO) and rent-stabilized counts from DOF tax bills (via JustFix), updated Oct 15, 2026. Heat season runs October 1 to May 31; season-to-date counts compare the same dates.
