42 Crosby Street

Seven stories, 97 feet, roughly 50,285 square feet of construction floor area on a lot of about 8,275 square feet with 114 feet of frontage — a corner-influenced site with elevations on both Crosby and Broome. The residential program is 10 units across floors two through seven, and the plan is disciplined: half-floor north and south residences on floors two, three, four and five; a single north residence on six; and a full-floor penthouse above.

Published architectural coverage of the project describes a facade of glass, stainless steel, aluminum framing and metal mesh, executed with prefabricated components — an explicitly contemporary composition whose proportions and materials are meant to answer the district's cast-iron vocabulary rather than imitate it. The same coverage describes Boffi kitchens and Bardiglio marble bathrooms in the residences, a porte-cochère with a living green wall, and a private car elevator serving the parking level. The ten-space accessory garage is documented independently in City Planning Commission records.

The recorded consideration on the sponsor sales — the ten residences conveyed between October 2017 and June 2019 — shows the shape of the product: half-floor residences clustered in a band, and a penthouse that transacted at roughly twice the highest half-floor. That spread is typical of a boutique building where the top unit carries the outdoor space.

LPC's permit record for the site is unusually legible, and worth reading as a sequence:

• 2008–2011 — an application under the 432 Broome Street address, withdrawn at staff level in May 2011.
• June 2013 — docket LPC-13-6801, resulting in a Certificate of Appropriateness for a new building.
• February 2014 — a miscellaneous amendment to the approved design.
• 2017–2018 — Certificates of No Effect and expedited certificates covering interior alterations, storefront elements, display windows, signband and bracket signage, as the ground-floor commercial space was built out for retail tenancy.
• 2019 through 2025 — a continuing file of interior-alteration and rooftop-related permits under the condominium lot, indicating that unit-level work here goes through LPC as a matter of course.

For a purchaser planning a renovation, that last point is the operative one. This is a new building, but it sits in a designated historic district, and anything that touches a facade opening, the storefront or visible rooftop equipment requires an LPC permit before DOB will issue one.

The building is young and its systems are original. A manual and automatic smoke-detection and sprinkler fire-alarm system with central-station connection was installed under filings in 2017 and 2018; the ground-floor retail space was built out in 2017 and renovated again in 2018; minor exterior work at the roof level was filed in 2019. The final certificate of occupancy issued in October 2020, three years after the first closings — a long temporary-certificate period, and one that is now closed.

The two commercial units are separately deeded and were conveyed in October 2018 and re-conveyed in March 2019, per ACRIS. Ask how their common-charge allocation is set and whether they carry any obligations for the porte-cochère, the garage or the shared entry sequence.

For a ten-unit condominium, the questions that matter are the reserve balance, the common-charge history, and whether the garage and car elevator are operated by the condominium or under a management contract — mechanical parking is a maintenance line that does not exist in most SoHo buildings. Request the last two years of financial statements and the current budget from the managing agent.

The declaration, by-laws and house rules govern, and they were not read for this page. The offering plan and eleven amendments are on file in The Roebling Research Library, but the copy on file is a scanned image without machine-readable text. Common-charge structure, pet policy, sublet policy, pied-à-terre treatment, and the treatment of LLC and trust purchasers should be obtained directly from the managing agent.

What is structurally true regardless: this is a condominium, so purchase approval runs through a waiver of the right of first refusal rather than a board interview, LLC and trust ownership are ordinarily accommodated, and financing is a matter between purchaser and lender rather than a house rule. Those are the practical advantages a buyer is paying for against the neighborhood's loft cooperatives.

Landmark review governs the exterior. Facade openings, storefront and street-visible rooftop equipment go through LPC. Build the review into any renovation timeline.

Recent sales

Recent closings at this building, curated by The Roebling Team research desk. Prices are the transfer amounts recorded with the NYC Department of Finance; apartment-level detail is checked against the building’s own file in The Roebling Research Library before publishing.

Market read. Most recent trades (2024) cleared a median $3,206/sf across 1 sale. Median listing discount 4.9% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-00483-7503) 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.

Confirm the parking right in writing. A ten-space accessory garage against ten residences implies allocation, but whether a given unit conveys with a space, a licensed right, or nothing at all is a document question. Get it in the offering plan or the deed, not from a floor plan.

Read the special-permit conditions. The residential use here exists under City Planning Commission special permits. Special permits carry conditions and approved plans, and material changes can require a modification. Your attorney should review the permit terms as part of diligence — this is not a standard as-of-right building.

Verify the certificate of occupancy is final and current. It issued October 9, 2020 after a long temporary-certificate period. Confirm nothing has reopened it.

Underwrite the small-building math. Ten residences carry a seven-story building with a garage and a car elevator. A single capital event moves the common-charge line in a way it would not in a large condominium. Ask for the reserve balance, the last two years of statements, and any assessment history. Run the True Monthly Carrying Cost Calculator on the real numbers.

Price the landmark overhead. Renovations that touch anything visible go through LPC. The building's permit file shows the process working, but it adds months.

Lead with what cannot be replicated. A new building inside the SoHo–Cast Iron Historic District, with parking, is a category of roughly one. That scarcity is the argument, and it survives a buyer's counsel's review because the approval record documents it.

Have the approval file assembled. The Certificate of Appropriateness, the City Planning special permits, and the final certificate of occupancy are what a diligent buyer's attorney will ask for. Providing them upfront prevents a re-trade.

Document the building's operating record. Six years of condominium operation, the reserve position, and any assessment history are the facts that distinguish a well-run boutique building from a thin one.

Be precise about the address. The building carries both 42 Crosby Street and 432–436 Broome Street in city records, and its condominium lot differs from the development lot. Materials that mix them create avoidable confusion in title review.
