Ocean Hill, Brooklyn

The records for Ocean Hill describe a neighborhood whose construction history skipped a generation. The median building here dates to 1910, and 75% of the recorded stock predates 1940 — both figures describing an area substantially built out before the modern zoning code existed. What follows is unusual: only 1% of buildings on file went up during the postwar boom of 1945 to 1975, a period that reshaped many nearby blocks with new apartment construction. Construction since 2000 tells a different story, accounting for 20% of recorded buildings, evidence of renewed building activity layered onto much older fabric. That pairing — a prewar median this early alongside a since-2000 share this size — describes two distinct waves of building activity on the same set of lots, decades apart.

Building-class records lean toward multi-family walk-up housing: 39% of buildings are recorded as walk-ups, 36% as two-family homes, and 6% as mixed residential-commercial. Land use follows a similar pattern, with 40% of parcels recorded as multi-family walk-up use against 38% as one- and two-family and 8% as mixed residential and commercial. Height runs a little higher, with a median of 3 stories and 1% of buildings recorded above 6 stories. Taken together, these figures describe a denser, more mixed building fabric than a purely one- and two-family block pattern would produce.

Zoning headroom is wide here: 86% of the roughly 3,900 lots carry unused floor-area capacity on record, with a median residual FAR of 1.1. That residual-FAR figure marks the recorded distance between what stands on a lot today and the maximum floor area its district permits. Lots run small, with a median of 2,000 square feet and a 90th percentile of 3,524 square feet.

87% of parcels carry a residential designation, and the roll counts 17,682 housing units across them. No lots here carry a recorded historic-district designation, and none are mapped inside a federal flood hazard area — 0% on both counts, a statement about today's map and landmark rolls rather than the area's history. Ocean Hill borders Bedford-Stuyvesant (East), Brownsville, Bushwick (East), Crown Heights (North), Cypress Hills, and East New York (North). The districts governing Ocean Hill are moderate-density apartment-house categories, the zoning family that permits the walk-up and two-family mix the records show.

In the city's classification, a walk-up building is a multi-family structure without elevator service, while the two-family and mixed residential-commercial categories describe exactly what their names suggest. None of Ocean Hill's stat families here are marked as coverage-gapped, so every percentage above — age, building class, land use, headroom — draws from data tracked directly for these roughly 3,900 lots rather than an estimate filled in around a missing category.
