470 Broome Street

Five stories on a fifty-by-one-hundred-foot corner lot, with rooftop additions above. The residential program is small and legible: north and south lofts on the fourth floor, and two duplex penthouses above them with terraces created by the rooftop additions; confirm each home's interior area and floor-plate configuration from approved plans. The roughly 9,000-square-foot aggregate residential area across four apartments is a gross ratio, not proof of each home's interior size or terrace allocation. The corner provides two street elevations and the window rhythm of the 1867 warehouse; evaluate the specific apartment's exposures.

The conversion re-established the exterior: a full façade restoration, window replacement across the second through fifth floors in 2006, and a new storefront infill approved by the Landmarks Preservation Commission in 2005 within the existing masonry opening. The rooftop additions were approved by the Commission in 2007 as a certificate of no effect, but the permit label alone does not establish setback or visibility. Read the approved plans and permit scope; LPC review also covers non-visible exterior work, and permit type depends on scope and LPC rules.

The north line is consolidating. A Department of Buildings NOW filing permitted in December 2025 covers the combination and renovation of apartments 4N and PH-N, including a new stair opening connecting the two floors. Recorded deeds show 4N and PHN in common ownership. If the combination completes, the building will hold three residential units rather than four — a meaningful change in an association with four residential and four commercial units, and one a buyer should factor into common-charge allocation and voting.

There is no doorman and no amenity program. The audited statements describe a bare operating budget: payroll and related expenses, utilities, water and sewer, repairs and maintenance, heating and air-conditioning maintenance, elevator maintenance, electrical repairs, security and alarm services, a management fee, professional fees and insurance. Insurance is the single largest line. The association capitalizes a resident manager's unit and personal property; everything else is owned by the unit owners in common.

The capital posture is the thing to underwrite. The statements on file report annual revenues and expenses each a little over $200,000, year-end cash near $105,000, members' equity under $75,000 and no replacement reserve. Their fiscal period is not identified in this profile, so these figures must not be presented as current. The auditor noted missing supplementary information on future repairs and replacements, and no reserve study was located in the reviewed file; the notes stated that the governing documents did not require reserve accumulation. In a building with four residences sharing a landmarked 1867 masonry envelope with a large commercial component, future façade, elevator or roof work must be assessed against current cash, reserves, charges, financing options and the declaration's allocation rules. Ask for the most recent financial statements, the current insurance certificate, the façade condition and whether the rooftop additions place the building within the Local Law 11 height threshold, and the commercial units' share of common expenses — and read the declaration for how costs are allocated between the residential and commercial sections.

Because the building is landmarked, exterior work runs through the Landmarks Preservation Commission, and the docket here is active: interior-alteration certificates through 2025, rooftop mechanical equipment approvals in 2025 and 2026, storefront awnings in 2026, and rope-access rear-façade inspections permitted in 2026.

The condominium holds a right of first refusal on both sales and leases, and the purchase application on file instructs applicants to protect themselves contractually against the board's exercise of it. That is the single most important transactional fact here: in an association with four residential units, the right of first refusal is not a formality.

Beyond that, the package is a standard condominium submission — application, credit authorization, occupancy rider, executed contract, employment reference, tax returns, financing commitment where applicable, and a supported financial statement. A working capital contribution equal to one month of common charges is collected at each closing, along with application, credit-check and move-in and move-out fees and refundable deposits; the seller pays a closing fee at transfer.

Pet, sublet and pied-à-terre rules are not established in the documents we hold. As a condominium the building has no co-op board interview; confirm financing limits, subletting and the right of first refusal in the current declaration, bylaws and house rules with the managing agent in writing rather than assuming a condominium default.

Recent sales

Recent closings 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. Most recent trades (2025) cleared a median $2,413/sf (recorded) across 1 sale. Median listing discount 9.3% 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 1-00486-7502; each condominium apartment is its own tax lot). 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 from recorded condo declarations and offering plans.

Read the certificate of occupancy before anything else. No certificate for this building appears in the city's dataset, and the 2015 application to revise it was approved without sign-off. Establish the current legal occupancy of the specific unit you are buying, and whether the JLWQ designation is still on the certificate.

Confirm the current reserve position. The statements on file report no replacement reserve, but do not establish the current position. Obtain the latest audit and capital plan for the four residential and four commercial units, including available cash, planned charges or assessments, borrowing and the cost allocation.

Understand the commercial majority. Two-thirds of the building's square footage is commercial, separately owned and never offered for sale. Read the declaration for cost allocation, voting and the boundary between the residential and commercial sections.

Factor the right of first refusal. Your contract needs language protecting you if the board exercises it. The managing agent's own instructions say so.

Watch the north line. A permitted combination of 4N and PH-N would take the building to three residential units; how common interests change depends on the declaration.
