Dyker Heights, Brooklyn

Dyker Heights' tax-lot records show 69% of lots recorded as one- and two-family use, the highest share among the neighborhoods in this batch, with multi-family walk-up use at 18% and mixed residential-commercial use at 8%. The building-class mix runs in the same direction: two-family homes make up 38% of the stock, one-family homes 31%, and walk-up apartment buildings 18%, describing a neighborhood built overwhelmingly around individual household ownership rather than rental structures. 95% of all lots carry a residential designation on record, among the higher shares in this set, and those lots hold 16,338 housing units in total. That combination of high one- and two-family land use and a high overall residential share describes a neighborhood built almost entirely around single households rather than rental buildings of any size.

85% of buildings on record predate 1940, and the median building dates to 1925. 8% of the stock was built during the postwar boom between 1945 and 1975, a somewhat larger share than in several neighboring sections, while just 2% has been built since 2000. None of the neighborhood's lots are recorded inside a designated historic district, leaving its low-rise character resting entirely on zoning rather than landmark protection. That absence of historic-district coverage means the neighborhood's low-rise pattern is a product of zoning and market choices rather than any formal landmark designation.

71% of the neighborhood's lots sit under their allowed floor-area ratio, by a median of 0.3 FAR, real but modest room to build. Buildings stay uniformly low here: a median of 2 stories, with none recorded above six floors. Lot sizes run a median of 2,008 square feet, with the largest recorded parcels reaching 4,000 square feet, a tighter spread than in some of the denser neighborhoods nearby, consistent with a neighborhood of fairly standardized rowhouse lots. A residual this shallow suggests most lots have already been built close to what their district permits, leaving only incremental room to expand.

The federal flood map draws no part of this neighborhood inside a mapped hazard zone on record, a statement about current mapping rather than the neighborhood's history with storms. Dyker Heights borders Bay Ridge, Bath Beach, Bensonhurst, Borough Park, and Sunset Park's central section, each carrying its own parcel-level record in this set, with its own construction timeline and its own land-use mix. Its five bordering sections span a wide stretch of southwest Brooklyn, from the harbor-facing blocks near Bay Ridge to the denser corridors toward Borough Park.
