About the building
378 12th Street is a four-story condominium built as a small new-construction project in Park Slope. Van Brody was the architect of record on the new-building application. The construction permit issued in April 2007, and DOB signed off the job in May 2011. That longer construction timeline accounts for the difference between the city's 2007 building date and the final signoff year.
The residences include two-bedroom, two-bath layouts with private outdoor space. The upper home has a substantial terrace adjoining its interior rooms, bringing outdoor living above the street. Central air and in-home laundry are part of the residential equipment.
Local Law 97
This building is below the 25,000 sq ft threshold at which LL97 limits apply to a building on its own. It is still covered if it shares a tax lot or condominium board with buildings totaling over 50,000 sq ft; confirm on DOB’s covered-buildings list.

Sales sourced from NYC Department of Finance recorded transfers (BBL 3-01030-7502; each condominium apartment is its own tax lot). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage from recorded condo declarations and offering plans.

What to know if you’re buying
The original tax benefit has ended, so older carrying-cost figures from the abatement period no longer describe the building's tax position. Four owners also share the cost of the exterior and roof; a terrace owner's private use should be distinguished from the association's responsibility for waterproofing and structural repairs.
Comparable buildings
- 392 11th Street: A nearby small condominium with balconies, a roof terrace and an expired tax benefit.
- 276 13th Street: A condominium of the same development period, with an elevator and ground-floor retail.
- 1638 Eighth Avenue: Low-rise condominium sections with a shared garage and a larger association.

How to read the facts on this page. Items attributed to an offering plan describe the building as it was offered at that filing — unit mix, square footage, the amenity program as planned. They are not a statement about how the building operates today. Tax and compliance figures are sourced separately to current City records and carry their own dates. House rules, staffing and fee policy can change by board resolution without any public filing: treat every policy line here as a starting point for diligence and confirm it with the managing agent. Where this page compares one building or neighborhood to another, that is our analysis of the recorded record — it names the measure, the period and the sample it rests on, and it is an observation about medians rather than a prediction about any particular apartment.
