THE CONDO BOOK PROJECT

100 Claremont Condominium

100 Claremont Avenue, Manhattan, NY 10025

Overview

Claremont Hall is a 40-story Morningside Heights condo built on the Union Theological Seminary campus. Here's what its offering plan says about the finishes, the pool and amenity floors, the non-union staff, the budget, and what sharing a building with a seminary means for you.

  • Size: 40 stories, roughly 354,000 square feet.
  • For sale: 165 apartments on floors 10 through the penthouse (the plan calls them "Tower Units"), plus a resident manager's apartment. Only 36 were offered at first.
  • Seminary space: 28 faculty and staff apartments on floors 4 to 6, 8 and 9 and an academic space in the cellar, all sold to the seminary.
  • Extras: 68 valet parking licenses and 24 storage bin licenses.
  • Plan accepted: April 2022.

Closingsfirst and latest recordedSep 15, 2023 – Aug 25, 2026

Sales recorded with the Department of Finance (ACRIS) through Sep 30, 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.

Budget

What It Costs to Run

The developer's first-year budget (projected for 2023) is about $4.7 million for the residential building. About 85% falls on the Tower apartments and 15% on the seminary's apartments. That works out to roughly $2,100 a month per Tower apartment on average, before property taxes; your share depends on your apartment's common interest.

  • Staff: about $1.26 million, the largest line.
  • Service contracts: about $690,000, more than two-thirds of it for the amenity and parking operators. Garage license fees offset about $250,000.
  • Utilities: roughly $950,000 for common electricity, gas, water and sewer.
  • Reserves: about $155,000 a year, plus contributions from buyers at closing. Buyers also pay two months of common charges to working capital.

Property taxes in year one assume a partly finished building, and the plan warns they'll rise once it's fully assessed. We didn't find a tax abatement in the plan. Compare buildings on our common charges and operating expenses pages, or read why operating costs differ.

The Building

Finishes

The plan lists finishes down to the model number. The developer can substitute items of "equal or better quality," so treat this as the planned spec.

  • Kitchens: Bosch appliances with a gas range or cooktop, quartz counters, painted MDF cabinets, a Kallista faucet and, in many layouts, a U-Line wine cooler. The range hoods recirculate rather than vent outside.
  • Primary baths: Kallista One fittings, Kohler Kathryn sinks (two in larger layouts), Toto toilets and, in some, a Kohler Underscore tub.
  • Secondary baths: Kohler Purist fittings with the same sinks and toilets.
  • Floors: 5½-inch engineered oak over a sound mat.
  • Windows: thermally broken aluminum windows by Wausau, with low-E glass and in-swing casements.
  • Laundry: a Bosch washer and ventless electric dryer in every apartment, mostly stacked.
  • Heating and cooling: in-unit water-source heat pumps on a loop heated by gas boilers. You pay for your heat pumps' electricity through a submeter.

Tip: some lines, including the G line on floors 10 to 23, have windowless storage rooms that the plan says can't be used for sleeping. For context, see bathroom brands in NYC luxury condos and NYC condo finishes since 2010.

Sharing a Building With a Seminary

  • Two boards. A Tower board sets Tower common charges. A seven-member condominium board runs the shared parts, and the seminary names one member.
  • A say on rule changes. While the seminary owns units, the condo documents can't be changed in ways that materially hurt its rights without its consent.
  • Shared costs can shift. The seminary pays an allocated share of shared expenses tied to the services it gets, so changes can raise or lower what Tower owners pay.
  • Easements. The seminary gave the building rights to vent the garage over campus land, to use exit doors onto its courtyard (expected to be used to move trash to the street) and to light, air and views over parts of the campus. An enclosed corridor, the Cloister, runs along the south side as a covered campus walkway.
  • Landmarks. The building isn't landmarked, but Brown Tower, James Chapel and James Tower on the same zoning lot are.

Amenities, Staffing & Transportation

The amenities are on the cellar, lobby, second, third and eighth floors and are shared with residents of the seminary's apartments.

  • Indoor lap pool: about 48 by 14 feet, on the second floor of the seminary's old Refectory, which is being renovated into the building. Panels can cover it so the room works as a meeting space.
  • Fitness center on the second floor, with locker rooms by the pool.
  • Third floor: a movement studio, maker's studio, music practice room and kids' playroom.
  • Lounges: a lounge, library and dining room off the lobby, and an eighth-floor lounge with a terrace.
  • Bike room for 101 bikes, free for owners.

Good to know: the courtyard next door belongs to the seminary campus and isn't open to Tower owners, and the building's amenities aren't open to seminary or Columbia students. Compare with amenities by building size.

Staffing and Services

  • A concierge 24/7 and a doorperson 16 hours a day, promised from the first closing.
  • A live-in resident manager, a handyman and four porters.
  • Outside companies running the valet garage and the amenities.

The plan says the staff will be non-union, which is unusual for a building this size. More on lobby costs in what a doorman costs a NYC condo.

Transportation

  • Subway: 6 min walk to 116 St-Columbia University 1; 125 St 1, 7 min

Fine Print

What's Specific to It

  • A seminary neighbor: the seminary owns 28 apartments and an academic space in the building, appoints a member of the condo board, and shares some costs.
  • Pool in a historic hall: the indoor lap pool sits in the seminary's renovated Refectory and can be covered to work as a meeting room.
  • Valet parking by license: 68 parking licenses for a valet garage, not assigned spaces.
  • Non-union staff: a 24/7 concierge, a 16-hour doorperson and a live-in resident manager, all non-union.
  • Gas cooking: Bosch kitchens with gas ranges or cooktops, unlike many new buildings.
  • Windowless rooms: some lines have storage rooms the plan says can't be used as bedrooms.

Claremont Hall is a 40-story condo tower at 100 Claremont Avenue in Morningside Heights, and it's an unusual one: it rises on a corner of the Union Theological Seminary campus and shares the building with the seminary.

Listing sites give you bedrooms and views. The building's offering plan, filed with the New York Attorney General, tells you the kitchen brands, who staffs the lobby, what the budget looks like and how the seminary arrangement works. Here's what we found. (New to these documents? Start with what a condo offering plan is.)

Fine Print Worth Knowing

  • Staged sales. The developer has no set timeline for releasing the remaining apartments.
  • Parking is a license, not a space. You can valet-park one car or motorcycle, split garage operating costs with other license holders, and unsold spaces can be rented short-term to outsiders. See how condo parking is sold.
  • Storage bins are in a cellar room that isn't climate controlled.
  • No resale for a year. You can't list or sell for 12 months after closing without the developer's approval.
  • Right of first refusal. The Tower board can match a sale or lease offer but can't simply approve or reject buyers.
  • Air rights are carved out. The plan says they won't be used to add floors here, but a transfer to a nearby site could affect views.
  • No smoking anywhere in the building, including apartments.

FAQ

Is Claremont Hall part of Union Theological Seminary?

Not exactly. It's a separate condo on part of the seminary's block, but the seminary owns 28 faculty and staff apartments and an academic space in the building and names one condominium board member.

Does Claremont Hall have a pool?

Yes, an indoor lap pool of about 48 by 14 feet in the renovated Refectory, next to the gym and locker rooms.

Is the staff unionized?

No. The budget says the staff will be non-union, with a 24-hour concierge, a 16-hour doorperson, a resident manager, a handyman and four porters.

Can Columbia or seminary students use the amenities?

No. The plan says the amenities aren't open to Columbia or seminary students, and the seminary's courtyard isn't open to Tower owners.
