15 Clark Street

The building is a six-story masonry corner house over a full cellar, holding both street walls with roughly 101 feet of frontage on Clark and on Willow. The engineer's report describes the fabric in detail: brick construction with a bluestone base, limestone band courses above the second floor, a metal cornice at the roof, and a core plan in which the single elevator and wrapped stair anchor each floor's five apartments. Kitchens and bathrooms sit on exterior walls for light and air; compare the actual window placement in any alternative apartment.

The inventory divides cleanly: three six-room, three-bath apartments per floor — the original 1904 layouts, with the corner exposures a 101-foot corner building makes possible — and two three-room units per floor from the 1939 division, documented under the building's amended certificate of occupancy. The cellar holds the superintendent's apartment, tenant storage bins, and building services. Department of Finance records carry 31 units, consistent with thirty apartments across six floors plus the superintendent's unit. Line-by-line layouts and share allocations are maintained in The Roebling Research Library and shared with clients during diligence.

Clark Street Tenants Incorporated has operated the building for more than five decades. Service runs to the small-co-op standard: a single elevator, a live-in superintendent, cellar storage, and laundry, without doorman staffing. The corporation's financial statements through the 2010s run in series in The Roebling Research Library; current management, reserves, and the capital program — in a building now past its 120th year, the envelope, elevator, and mechanical cycles deserve particular attention — should be reviewed during diligence. The Roebling Team remains the contact of record for transaction questions.

Sales sourced from NYC Department of Finance recorded transfers (BBL 3-00229-0001). 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.

Compare the six-room lines with matched alternatives. Three baths, corner light, and Edwardian room scale a block from the Promenade — compare dated sales, condition, access and carrying costs in staffed Pierrepont buildings and townhouses. Understand which vintage of layout you are buying: original 1904 line or 1939 division.

Underwrite the building's age honestly. Review inspection and repair records for the envelope, windows, elevator and mechanical systems alongside the capital plan and reserves. The reported six-story building is below FISP’s higher-than-six-stories threshold; age alone does not establish its present repair cycle relative to a 1920s building.

Know the neighborhood's two speeds. Clark Street toward Henry carries the station, the Watermark, and the St. George's institutional afterlife; visit Willow Street south of the corner and the apartment’s actual exposures at different times to assess sound. The corner gives you both — decide which exposure suits.

Expect small-co-op process. Roughly thirty apartments, board approval, and policies on pets, subletting, and financing set at the board level and confirmed at offer stage.

Describe the documented layouts. Six rooms and three baths in a district co-op is a headline; lead with the room count and the corner light, and price against townhouse-alternative buyers as well as co-op shoppers.

Use the corner's history. The St. George story, the Promenade a block west, and the express station two blocks east give the listing narrative texture few Heights buildings match.

Have the century-building file ready. Buyers' engineers will focus on the envelope and mechanicals; documented inspection and capital records help buyers assess current condition, without guaranteeing a negotiation outcome.
