Bath Beach, Brooklyn

Bath Beach's construction record stands apart from its neighbors: only 54% of buildings predate 1940, the lowest prewar share in this set, while 28% date to the postwar boom between 1945 and 1975, the highest such share recorded here. The median building on record dates to 1935, later than most of the surrounding sections. Just 4% of the stock has been built since 2000, a modest but real share of newer construction layered on top of an already postwar-leaning neighborhood, a construction profile unlike any other section in this batch. That later median year, together with the outsized postwar-boom share, marks Bath Beach as the newest-skewing building stock among the ten neighborhoods gathered in this set.

By land use, 62% of lots are one- and two-family use, 26% multi-family walk-up, and 8% mixed residential and commercial. Building class runs a similar course: two-family homes total 51% of the stock, walk-up apartment buildings 25%, and one-family homes 11%, the heaviest two-family concentration in this batch, describing a neighborhood built almost entirely around small, owner-occupied structures rather than larger rental buildings. That heavy two-family concentration, paired with a modest one-family share, suggests a neighborhood built mostly for small households rather than larger rental structures.

A 0.2 FAR median residual runs under 59% of Bath Beach's lots, the thinnest gap recorded in this set, though it still touches most of the neighborhood, consistent with a postwar building stock already built close to what its districts permit. Buildings sit low throughout: a median of 2 stories, with none recorded above six floors. Lot sizes run a median of 2,127 square feet, with the largest recorded parcels reaching 4,167 square feet. A gap this shallow leaves little room for a lot to support a meaningfully larger structure without a zoning change or a lot combination.

96% of lots are recorded as residential, carrying 12,845 housing units. Federal flood-hazard mapping shows none of the neighborhood's lots inside a designated zone on record, a statement of current coverage, not a claim about the land's history with water. Bath Beach borders Bensonhurst, Dyker Heights, and Gravesend's western section, all covered elsewhere in this set, each with its own construction era and its own development headroom. Its three bordering sections, Bensonhurst, Dyker Heights, and Gravesend's western blocks, each carry an older, more prewar-leaning construction record than Bath Beach itself, underscoring just how far this section's postwar tilt stands out from its immediate surroundings.
