Mapleton and Midwood West

This area joins two places. Mapleton is the low-rise blocks around 18th to 23rd Avenues between roughly 50th and 62nd Streets. Western Midwood is the Ocean Parkway corridor from about Avenue H to Avenue P. Mapleton was developed from the 1910s, when the Sea Beach subway line arrived, with many homes on 30-by-100-foot lots. Ocean Parkway has larger apartment houses. PLUTO counts about 13,100 homes, and about 68% are in buildings from before 1940. The F train runs along McDonald Avenue, stopping at Avenue I, Bay Parkway, Avenue N and Avenue P. The N's 20th Avenue station is just off the edge. Friends Field and Gravesend Park, on 18th Avenue, are the main parks.

Mapleton and Midwood West has 9,235 open HPD housing violations, 1,305 of them Class C (immediately hazardous). Inspectors issued 2,458 new violations here in the last 12 months. That's the 45th most open violations of 53 neighborhoods in Brooklyn.

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: Ocean Parkway corridor starts at Avenue H (PLUTO lots on Avenue H fall inside); 1910s development tied to the Sea Beach line and 30x100 lots per Wikipedia; Gravesend Park 1917 acquisition and 18th Avenue location confirmed on NYC Parks; Friends Field (6.7 acres) is slightly larger than Gravesend Park (6.38). 20 Av (N) is about 100 m outside the polygon.

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