171 23rd street

Pre-war Brooklyn multifamily house, three stories over a garden level on a 22 x 100 ft lot. HPD classifies the building as an Old Law Tenement (BIN 3009402); DOF building class C0/C3 (three-to-four family). 3,080 sf gross, 2,310 sf residential, built lot-line to lot-line at a 1.40 built FAR. No elevator — a walk-up.

Interiors were gut-renovated under DOB alteration filings B00703160 and B00679515, filed April 2022 and signed off through 2022-23 (approx. $179,000 combined declared cost, covering plumbing, mechanical and structural work with no change to use, egress or occupancy). Post-renovation marketing for the units cites roughly 10-foot ceilings, renovated kitchens and updated bathroom fixtures.

Renovated kitchens with stainless steel appliances; washer/dryer in unit.

In-unit laundry in the renovated apartments. Three-story walk-up — no elevator, no doorman, no on-site parking and no shared amenity space; the appeal is the full-floor layouts and the renovation rather than building services.

Built in 1899, one of the small speculative multifamily houses put up along the 20s streets between Green-Wood Cemetery and the Brooklyn waterfront as the district filled in around the industrial terminal. It carries HPD's Old Law Tenement designation, the pre-1901 tenement standard. The building sat with no DOB filings of record until April 2022, when the current ownership filed a full interior renovation of the four apartments — plumbing, mechanical and structural — completed through 2022-23 with no change to the building's use, egress or occupancy. The block sits in an M1-2D special mixed-use zone, a legacy of the corridor's manufacturing past.
