About the building
42 King Street retains the proportions of an 1840 Greek Revival row house: three brick-faced stories above a brownstone basement, a raised entrance and a dentiled roof cornice. Its straight-edged stone doorway, sidelights and iron stoop railings survive from the domestic architecture that LPC singled out when designating the district. The house was formally divided into apartments in 1967 and became a cooperative four years later.
The roughly 20-foot-wide building contains floor-through apartments and a larger garden duplex formed from lower-floor space. Upper homes have front and rear exposures, while the lower residence opens to a private garden. The larger combined layout spans approximately 2,244 square feet. Interior stairs and the original shared staircase remain important parts of circulation; upper apartments are reached on foot. The self-managed ownership structure places routine building decisions directly with a small group of shareholders.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-00519-0018). 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 on co-ops is not officially recorded, figures shown are approximate.

What to know if you’re buying
Past combinations have crossed the party wall. A 2024 court decision documented a historic connection between a parlor-floor apartment here and rear accommodation in the adjoining cooperative, with separate proprietary leases and a later agreement requiring the opening to be closed. For a home connected with that history, the current legal boundaries and completion of the separation work are specific transaction questions.

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.
