About the building
393 4th Street is a four-residence condominium created in 2009 within a prewar masonry building. It forms part of a brick-and-stone row associated with builder Louis Bonert. Rounded window bays, stone trim and a brownstone base give the façade depth, while classical entrance details distinguish the individual buildings in the row. The property sits outside the Park Slope Historic District.
The upper residences are three-bedroom floor-throughs of roughly 1,450–1,500 square feet. A larger lower duplex has garden access, and private roof-deck space accompanies upper accommodation. The homes have individual heating and cooling equipment and in-home laundry, with private storage rooms in the basement. The self-managed condominium is a walk-up, so access to the upper floors is by the common staircase.

Full closing history with price-per-square-foot over time, the complete retrade record, and every line that has traded.
Sales sourced from NYC Department of Finance recorded transfers (BBL 3-00983-7505) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. 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 former J-51 benefit should not be carried forward as an active tax saving. This is also a four-owner association with private outdoor areas above and behind the building: roof waterproofing and garden drainage can involve common structure even where use belongs to one apartment. Those allocations affect how a small association divides major repair bills.

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.
