37B Crosby Street

Six stories in 8,400 square feet over a footprint of roughly 50 by 28 feet gives about 1,400 square feet of gross building area per floor, not apartment interiors. Listing records describe one residence per floor, with the ground-floor home extending into the cellar and opening onto the rear garden; confirm individual areas and configuration from plans. Department of Buildings filings corroborate the plan: a 2010 renovation of the fifth-floor apartment, a 2016–17 renovation of the fourth-floor residence, and a 2020 job covering interior demolition and new partitions across the cellar and first floor, including a relocated kitchen and bathroom and a new connecting stair with associated framing. Mechanical, plumbing and sprinkler work for those levels followed through DOB NOW.

LPC's database records two building identification numbers on this tax lot — 1076936, which carries the 37B address and all the filings, and 1076934, which carries none. Confirm the footprint against the survey rather than against PLUTO's single-building assumption.

The records reviewed do not establish the building's date, architect or original use. LPC's entry reads "not determined" in every one of those fields, while its entries for the neighboring front buildings are precise. PLUTO's 1900 is a placeholder. A more precise year requires additional primary documentation; the missing attribution here does not prove no such record exists.

There is very little to operate: six homes, no elevator, no doorman, no amenity program, a shared entrance passage and a rear garden. Buildings at this scale run on a small managing agent, a part-time porter or none, and a board that is effectively the entire shareholder body.

That structure has two consequences worth pricing. Per-share exposure to any capital event is concentrated — a facade cycle in a landmarked district, a roof, or a boiler is divided six ways rather than sixty. And there is no institutional buffer: the building's financial position depends entirely on whether six households have chosen to fund a reserve. Ask for three years of financial statements, the reserve balance, the underlying mortgage and its maturity, and any assessment history, and read them before contract.

The lot sits inside the SoHo–Cast Iron Historic District Extension, designated May 11, 2010, whose eastern subsection runs along Crosby and Centre Streets. Inclusion was verified by querying LPC's own building database by block and lot, because PLUTO's historic-district field is unreliable in both directions. Two further confirmations sit in the record: the City recorded a landmark notice against this lot in ACRIS in August 2011, and every Department of Buildings filing since 2010 carries the landmarked flag where 2003 filings do not. LPC requirements depend on scope: ordinary maintenance can be exempt, qualifying work can receive staff approval and other work may require a Commission hearing. Interior work needing DOB permits can also require LPC approval, even when not visible from the street.

Zoning is M1-5/R7X within the Special SoHo-NoHo Mixed Use District, adopted in December 2021. Before that rezoning, the manufacturing districts governing this stretch of Crosby Street limited residential occupancy to Joint Living-Work Quarters for Artists — the category that carried SoHo's loft population for four decades. Whether the residences here are documented as JLWQA units or as conventional Class A dwellings cannot be answered from the public record: no certificate of occupancy for this building appears in the Department of Buildings online series, and the building predates it. This is the single most important open item in diligence. The certificate of occupancy on file at DOB and the proprietary lease will answer it; nothing else will. The 2021 rezoning permits residential use in the district, which reduces the practical risk considerably, but it does not retroactively amend a certificate of occupancy.

No Loft Board designation appears on any filing, and there is no J-51 for this lot or its parent lot in any year — so the conversion carried no tax benefit and left no Loft Law trail.

The reviewed materials leave several policy terms unresolved. No offering plan was located in either document library. Two terms are documented — 80% maximum financing and pied-à-terre use permitted; confirm both. Minimum down, post-closing liquidity standard, sublet policy and fee, flip tax and its calculation, acceptance of trusts, LLCs and guarantors, pets and alterations — all of it must come from the managing agent in writing before an offer, and be confirmed by your attorney against the proprietary lease and house rules. Some of these terms may rest on board practice rather than written policy, which is all the more reason to get them in writing. That is not a red flag; it is a diligence obligation.

Recent transfers at this building, from The Roebling Research Library. 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. $/sf is measured on the latest sales with reliable square footage (2021): a median $1,563/sf (recorded) across 1 sale. The building has traded as recently as 2022. Median listing discount 4.8% 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 1-00473-0130). 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.

You are buying shares, not real property. Approval runs through the board, financing is capped by the corporation (80 percent of the purchase price on the documented terms; confirm the current rule) as well as by your lender, and the corporation's balance sheet sits underneath your apartment. In a six-unit house all of that is unusually consequential and unusually easy to verify, because there is so little of it.

Resolve the certificate of occupancy first. Whether the residences are of record as artists' joint living-work quarters matters to your lender, your title company and your resale. Order it from the Department of Buildings and read the proprietary lease before you commit.

Do not confuse the addresses. 35 and 37 Crosby Street are separately owned buildings on separate lots; 30 Crosby Street is a condominium on the same block; 42, 45 and 16 Crosby Street sit on three other blocks entirely.

For sellers: the privacy is the product, and the policy stack is the friction. A seller who arrives with the financing ceiling, sublet terms and flip tax already documented from the managing agent, plus the reserve balance and underlying mortgage terms, gives buyers documents to review early; it does not eliminate other diligence questions or guarantee a closing timeline. Run the Co-op Board Qualification Calculator against a conservative financing assumption before you accept an offer.
