74 Diamond Street

The new-building filing describes a four-story building with a penthouse level and cellar, six dwelling units and 6,528 square feet of construction floor area. PLUTO records a 25-by-100-foot lot, a 24.6-by-51-foot building and 5,361 square feet of building area. The first permit report, from 2019 filings, described a 50-foot masonry building with five residences, about 4,995 square feet of residential space and a 35-foot rear yard, with A&T Engineering as architect of record. The unit count rose from five to six on later filings.

Sales materials describe a six-residence condominium of one- and two-bedroom homes, some of them duplexes, with floor-to-ceiling windows, a neutral palette and stone detailing. An earlier project record listed storage units, a shared roof deck, central air conditioning and private yards for select residences. None of that is confirmed against the plan, which is the document to read for finishes, outdoor space and amenities.

Structural and excavation-support work signed off in February 2025, and excavation and foundation work in July 2025. PLUTO's year built of 2023 is early for a building whose trade sign-offs run through May 2026. We found no certificate of occupancy in the Department of Buildings records pulled.

Per the offering plan filed with the New York State Attorney General (plan CD250165), the plan was submitted May 20, 2025 for six residential units at a total offering price of $6,792,500. The record shows the same initial and current price and no acceptance or effective date. The sponsor is 74 Diamond, LLC.

The Attorney General database returned an error when we pulled this record, so the dates and prices come from our scan of September 27, 2026. Amendments were not reviewed.

Until the Attorney General accepts the plan, the sponsor cannot sign purchase contracts or take deposits or reservations, binding or non-binding; an interest list does not secure a unit.

A brokerage sales page for the project was live in November 2026 with a published range of $850,000 to $1.5 million. Unit-level asking prices were not retrievable, and the range is a marketing figure, not a set of contract prices. Six homes averaging $1.13 million fit inside that range. Because the plan is not accepted, treat the range as indicative only.

Wait for acceptance. Nothing is binding before the Attorney General accepts the plan. Price, unit count and unit mix can still change by amendment, and the unit count has already moved once on the permit record.

Developer. Two project records name two different developers. Ask who the sponsor's principals and builder are before you rely on either name.

Closing costs. In sponsor sales the buyer customarily pays the New York State transfer tax (0.4%) and the New York City real property transfer tax (1.425% above $500,000), plus the state mansion tax of 1% at $1 million and above. On a $1.13 million home that is about $20,700 in transfer taxes and $11,300 in mansion tax before any gross-up. Homes under $1 million owe no mansion tax. Use the calculators below to run your price.

Certificate of occupancy. Closings follow a certificate of occupancy, usually a temporary one. Ask what the sponsor holds back until a final one issues.

Carrying costs and abatement. The plan's budget sets common charges and projected real estate taxes. No tax abatement has been disclosed.
