Closingsfirst and latest recordedNov 30, 2023 – Jun 10, 2024

Sales recorded with the Department of Finance (ACRIS) through Aug 31, 2026: deeds, or transfer tax filings for a building on leased land, of $10,000 or more. A home's first sale since the plan was filed is the sponsor's closing; resales aren't counted. Closing prices are compared with the same home's Schedule A price, as first offered; a deed covering more than one home isn't compared. Amendments often change prices before a home closes, and a deed that includes parking or storage counts its full price. ACRIS records a sale weeks after closing, so recent contracts don't appear yet. Every building's sales.

Budget

What It Costs to Run

The sponsor's first-year budget (December 2022 to November 2023) covers the whole building, about $7 million, split among condos, rentals, retail and commercial units. The condo homes' share is roughly $3.2 million.

  • Common charges: Schedule A estimates range from about $700 a month for the smallest homes to about $5,150 for the largest penthouses, roughly $1,800 on average, with property taxes on top
  • Amenity costs: about $530,000 to run Commercial Unit 3 (roughly $350,000 for operations and cleaning and $180,000 in real estate taxes), split with the rental unit, plus the $450,000 amenity usage fee paid only by condo owners
  • Reserves: about $145,000 a year, based on a reserve fund study, plus a working-capital contribution of two months' common charges at closing

Good to know: the amenity fee is effectively a fixed cost. Benchmark the numbers with our common charge and operating expense tools, and read why operating costs differ.

The Building

Finishes

The plan lists finishes down to model numbers, subject to substitution with items of "equal or better quality."

Kitchen

  • A full Miele appliance package: refrigerators (24, 30 or 36 inches depending on the layout), convection and speed ovens, gas cooktops (24 or 36 inches) and dishwashers
  • XO Ventilation hoods, U-Line wine refrigerators in some layouts, and a Waterworks faucet over an Elkay sink

Bathrooms

  • TOTO toilets with bidet seats and Geberit push plates
  • Waterworks fittings throughout: faucets, shower heads, hand showers, thermostatic trim and tub fillers, plus Waterworks Clara undermount sinks
  • Soaking tubs from Kohler, MTI and Zuma, depending on the bathroom (compare bathroom brands in NYC luxury condos)

Floors, Windows and Laundry

  • Floors: 5/8-inch select-grade European white oak from P.C. Hardwood Floors over an acoustic underlayment
  • Windows: a glass curtain wall with fixed panes running nominally floor to ceiling. Only about 30% of units include operable windows, and those open as top-hung awnings limited to a 4-inch gap, with no screens.
  • Laundry: every home gets a Miele compact washer and a ventless heat-pump dryer; there's no common laundry room

Heating and Cooling

Five gas-fired condensing boilers feed hot water into a two-pipe system, and tower apartments get Bulldog hybrid heat pumps with programmable, zoned thermostats. Rooftop cooling towers handle cooling.

Good to know: ceilings are typically dropped in places for beams and ductwork, so check the plan's ceiling-height table. More in NYC condo finishes since 2010.

Amenities, Staffing & Transportation

The main amenity package lives in Commercial Unit 3 on floors 7 and 8, shared between condo owners and rental residents. The plan anticipates:

  • A large terrace with an outdoor swimming pool and whirlpool spa
  • Locker rooms, a billiards room, a kids' playroom and a screening room
  • A lounge, a private dining room and a catering kitchen

Other spaces in the building:

  • Common terraces at certain setbacks for "passive recreational use," which the board can limit by capacity, noise, weather and glassware, and where children under 18 may need a chaperone
  • A fitness center in Commercial Unit 2, expected to be open to the public, so membership terms are set by its operator, not the condo

Tip: the plan warns that some amenities and the full staff may not be ready until about 18 months after the first closing, and the pool and spa up to 24 months. Compare amenities by building size.

Staffing and Services

Staff is shared across the whole building, rentals included. The first-year budget projects a resident manager and assistant manager, two handymen, a 24/7 concierge, a lobby attendant 16 hours a day and eight porters. Wages follow Local 32BJ union rates, and payroll comes to roughly $2.1 million, the biggest line in the budget. The full staff may not be hired until occupancy reaches certain levels. For how staffing drives costs, see what a doorman costs in an NYC condo.

Transportation

  • Subway: 2 min walk to DeKalb Av B Q R; Hoyt St 2 3, 3 min

Fine Print

What's Specific to It

  • You don't own the amenity space. The pool and lounges sit in "Commercial Unit 3" on floors 7 and 8, always owned with the rental unit. Condo owners share its costs but have no say in how it's run.
  • The amenity fee has a floor. Condo owners also pay a $450,000 first-year amenity usage fee that can't be cut without the affected owners' consent.
  • The gym is a public business. Commercial Unit 2 is expected to be a public fitness center, open to residents on the same terms as anyone else.
  • Your building manager lives in the rental. The resident manager is expected to occupy a leased apartment (anticipated as 12A) in the rental portion.
  • Parking is down the street. The sponsor reserved 90 spaces in a public garage at 189 Schermerhorn Street, first come, first served.
  • Storage lockers are licensed, not owned. 182 subcellar lockers (about 16 to 36 square feet) are licenses tied to your apartment; the sponsor keeps the initial proceeds.

The offering plan, the condo document the developer filed with the New York Attorney General, shows who owns what and who pays for what. That matters here, because you're buying a slice of a large mixed-use building. (New to these? See what a condo offering plan is.)

Fine Print Worth Knowing

  • A condo inside a bigger condo: the building began as an 11-unit condominium, with all the homes in one "Primary Residential Unit" later split into 149. The rental, retail and commercial units are separate owners with their own rights.
  • Neighbors you don't control: retail and commercial units can be used for almost any lawful purpose, which the plan warns may bring noise or odors, and condo owners get none of their revenue.
  • Off-site parking isn't guaranteed: the 90 reserved spaces at 189 Schermerhorn Street are rented monthly through the garage operator at its rates, and the sponsor doesn't promise you'll get one.
  • Tax breaks are for the shops: the sponsor plans to seek ICAP tax benefits for the retail units and possibly some commercial units, for up to 25 years. The plan doesn't describe an abatement for the condo homes.
  • The landmarked portion: the building includes a restored landmarked portion with its original cast-bronze windows kept and reglazed. It holds retail units only.

For how parking deals like this one compare, see sold, licensed and leased parking.
