Park Slope, Brooklyn

More than a third of Park Slope's tax lots — 39% — sit within a recorded historic district, the largest such share of any neighborhood covered in this batch, ahead even of neighboring Carroll Gardens-Cobble Hill-Gowanus-Red Hook. The designation overlays a building stock that is close to fully prewar: a median construction year of 1901, with 96% of recorded buildings predating 1940 and 0% from the 1945-to-1975 postwar boom, a construction profile with almost no representation from the middle decades of the twentieth century. Few neighborhoods in this batch combine that level of formal historic protection with such a heavily prewar building stock, and the two figures together describe a place whose form has been both old and formally preserved for a long time.

Recent construction is nearly absent from the record — just 2% of buildings date to 2000 or later, one of the lowest shares in this set of pages. Walk-up apartment buildings lead the building-class mix at 38%, with two-family homes at 33% and mixed residential-commercial buildings at 9%, at a median height of 3 stories, taller on average than most of the low-rise pages to its south, and consistent with a denser mid-rise fabric than the rowhouse blocks that surround it. That combination — a taller median height than most nearby blocks, paired with an almost complete absence of recent construction — describes a building stock substantially finished before the current century began.

The land-use record splits closely between multi-family walk-up use (41%) and one- and two-family use (42%), with 12% recorded as mixed residential-commercial — a denser mix than in most of the surrounding rowhouse blocks toward Windsor Terrace-South Slope. 96% of Park Slope's roughly 6,700 lots are recorded as residential, holding a combined 34,084 units, one of the larger unit totals among the neighborhoods profiled in this batch. The near balance between one- and two-family use and multi-family walk-up use, without one category dominating the way it does on several nearby pages, sits inside the same footprint the historic designation protects.

Lots run small and consistent: a median of 1,900 square feet, reaching 2,750 square feet toward the high end. None of Park Slope's lots are mapped inside the federal flood zone on current data (0%). Lot sizes here run narrower than in several of the neighboring pages, consistent with a rowhouse-scale subdivision pattern that has held for more than a century.

72% of lots carry recorded floor area still below their district cap, at a median residual of 0.5 FAR — comfortable room by the numbers, on a stock that mostly hasn't used it in over a century, bordered by Fort Greene and Prospect Heights to the north, where the record shows a different mix again of building age and land use, illustrating how much these figures can shift within just a few blocks of Brooklyn.
