South Jamaica, Queens

South Jamaica shows the most recent construction of any neighborhood in this batch: 13% of its buildings date from 2000 or later, the highest since-2000 share recorded here, even as the median construction year sits at 1930 and 63% of the stock predates 1940. Only 12% of buildings date from the 1945-to-1975 postwar boom, so building activity split mostly between the prewar era and the current century, with a noticeably quieter middle stretch in between. That two-peaked construction pattern is unusual among the neighborhoods in this set, most of which show one dominant building era rather than two.

Class records split closely between one-family and two-family homes, at 42% and 40% respectively, with 5% recorded as class C walk-up apartment buildings, across roughly 7,000 tax lots. Land-use coding shows 82% of lots as one- and two-family residential, 5% multi-family walk-up, and 4% vacant land. 91% of all lots carry a residential designation, holding 12,946 units, and the recorded median building height is 2 stories, with no building tall enough to register above 0% at the 6-floor mark these records track. That near-even class split, paired with a small vacant-land share, describes a lot base that is fully built out but not concentrated in any single housing type.

Development records show 88% of lots carrying unused floor-area capacity against current district rules, with a median residual of 0.4 FAR. Flood-map and historic-district records both come back at 0% for this footprint, the same as most of its southeast Queens neighbors. Lot sizes run to a median of 2,500 square feet, with the 90th percentile reaching 4,320 square feet, among the tighter, more compact lot profiles recorded in this set.

South Jamaica borders Baisley Park, Jamaica, South Ozone Park, South Richmond Hill, and St. Albans on record, several of which show a similar prewar-heavy construction-year profile at the same tax-lot detail available per parcel, even where their since-2000 shares differ noticeably from South Jamaica's own.

The combination of a majority prewar building stock and the highest since-2000 construction share in this batch describes a neighborhood where older and newer construction sit side by side more than in most of the surrounding footprints, several of which show building activity staying concentrated in a single earlier era rather than spanning both ends of the timeline. That pattern holds even though South Jamaica's class mix, lot sizes, and flood-map status all track closely with its immediate neighbors.
