Sunset Park (East)-Borough Park (West), Brooklyn

Sunset Park (East)-Borough Park (West)'s development records carry the deepest median gap in this set: 81% of its roughly 2,600 tax lots hold recorded floor area below what current rules allow, at a median residual of 1.2 FAR, the largest per-lot gap recorded among the neighborhoods profiled here, even where the share of lots with any headroom at all runs slightly behind a few neighboring sections. The land-use mix is comparatively mixed: 37% one- and two-family use, 35% multi-family walk-up, and 18% mixed residential and commercial, without one category clearly dominating the neighborhood's blocks, a more even split than in most of this batch. That evenness across land use, alongside the depth of its development gap, sets this section apart from neighborhoods where a single figure dominates almost every measure.

The building-class breakdown runs close to even too: walk-up apartment buildings account for 35% of the stock, two-family homes 34%, and mixed residential-commercial buildings 13%. 90% of buildings on record predate 1940, with a median construction year of 1925. The postwar boom between 1945 and 1975 claims just 3% of the stock, while 5% has been built since 2000, a modest but real layer of newer construction on an otherwise prewar block. That layering of a prewar majority with a modest but real postwar-boom and post-2000 share mirrors a pattern seen in only a few other sections of this batch.

The median building holds at 2 stories, and 1% of buildings on record exceed six floors. Lot sizes run a median of 2,285 square feet, with the largest recorded parcels reaching 3,807 square feet. None of the neighborhood's lots are recorded inside a designated historic district, leaving its character resting on zoning rather than landmark protection, the same as several of the low-rise sections nearby. That absence of historic-district coverage leaves the neighborhood's redevelopment potential resting entirely on its zoning and lot dimensions rather than any landmark rule.

91% of lots are recorded as residential, carrying 27,172 housing units. The current federal flood-hazard map places none of the neighborhood's lots inside a designated zone on record, describing today's boundary rather than any history with water. The section borders only Borough Park and Sunset Park's central blocks in this set, fewer direct neighbors than any other neighborhood profiled here, though PearlAudit's underlying records extend to the individual parcel level throughout. Even with the fewest direct neighbor links in this set, the section's development figures, the deepest median gap recorded here, make it one of the more distinctive profiles in the batch.
