229 West 97th Street (The Powellton)

Boylan built to the full corner: roughly 101 feet on Broadway by 150 feet along West 97th Street, irregular, carrying about 72,500 square feet of building area of which roughly 67,700 is residential and 4,800 commercial. Seven stories, beige brick, limestone trim, neo-Renaissance detailing, and the tripartite 97th Street elevation created by the light courts.

The apartment stock is prewar in the terms that matter. Ceiling heights are reported at ten to twelve feet, windows are oversized, floors are hardwood, and decorative fireplaces survive in a number of residences. Renovated apartments commonly carry exposed brick and restored moldings. Layouts are irregular — the light courts mean that no two lines on a floor are quite alike, and the Broadway-facing rooms have a different acoustic and light profile from the 97th Street rooms and the court-facing rooms.

Combination history is real here and is worth understanding before you tour. Department of Buildings filings from 2003 forward record apartment combinations, and the unit counts reported on those filings drift between 55 and 61 across two decades — the signature of a building whose apartment count has been reduced by mergers. Listing records show merged unit designations. The practical effect is that the building's large apartments are assembled rather than original, and that the floor plan you are looking at may not repeat anywhere else in the building. Line-to-line comparison is unreliable at The Powellton in a way that it is not at a building with a uniform stack.

The cooperative runs a full-service prewar operation: a restored lobby, a full-time doorman, a live-in superintendent, central laundry, bicycle storage and private storage, per management-sourced records. There is no fitness center, garage or roof deck documented in city or management-sourced records — this is a service building, not an amenity building, and its maintenance should be evaluated on that basis.

Two operating facts deserve weight at diligence. The first is the absence of commercial income already discussed: the Broadway storefronts belong to third parties, so the co-op does not receive their rent. Determine their obligations for shared building expenses from the condominium declaration and accounts. The second is the June 2025 mortgage consolidation to $1.6 million, replacing a facility carried since the early 2000s. Verify current balance, rate, maturity, covenants and reserves; that historical principal alone does not establish future borrowing capacity or freedom from assessments for façade and roof work.

The building has carried Local Law façade work in the past, including a filing in 2014. Ask for the current LL11 cycle status, the reserve balance, and the assessment history in the same request.

Ownership form: Condop. Purchases are cooperative share transactions with a board package, board interview and board approval. Budget the longer timeline a co-op purchase requires.

Pets: Permitted, cats and dogs, per management-sourced records.

Subletting: Permitted, and characterized as liberal in management-sourced records. Confirm the current term limit and sublet fee with the managing agent — sublet policy is the most frequently amended house rule in any cooperative.

Pied-à-terre, parents buying, gifting and guarantors: All permitted per management-sourced records. That combination is unusual on the Upper West Side and materially widens the buyer pool relative to stricter neighboring cooperatives.

Financing and minimum down payment: Not documented in public records. Confirm the current financing ceiling with the managing agent before writing an offer.

Flip tax: Not documented in public records. Confirm with the managing agent before pricing a sale.

Real estate taxes: No J-51 or other building-wide abatement appears on the residential unit lot in any assessment roll from FY2011 forward. Taxes are embedded in maintenance; there is no burn-off to model, but the bill still moves with assessments and rates, so check the current one.

Recent sales

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. Most recent trades (2026 to date) cleared a median $1,061/sf (floor-adjusted) across 4 sales. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above. Median listing discount 4.5% 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 1-01869-7501). 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 a condominium unit. Every city record and several marketing sources will tell you this is a condominium. It is a condop. Plan for a board package, an interview, and cooperative financing terms.

Confirm the flip tax and the financing ceiling in writing. Neither is documented in public records for this building. Both change your net and your qualification, and both are questions for the managing agent before you write an offer.

Read the maintenance with the retail question in mind. The Broadway storefronts are not the cooperative's. Do not assume commercial rent is subsidizing your maintenance here, because it is not.

The low underlying mortgage is a genuine asset. A consolidated $1.6 million across 55 apartments as of June 2025 is light. Ask what the board intends to do with that capacity, and whether any capital project is in planning.

Do not assume landmark protection. Six lots on this block are inside the Riverside–West End Historic District Extension II. This one is not. There is no Landmarks review on exterior work here, which cuts both ways — cheaper capital projects for the cooperative, less protection against change on the block.

Walk the specific line. Boylan's light courts mean the floor plans are irregular and the combinations are one-offs. Court-facing, Broadway-facing and 97th-Street-facing rooms are three different products inside one building.

Lead with the structure, correctly stated. Buyers and their attorneys will discover the condop wrapper. Explaining it up front — including why it exists and what it does — reads as command of the asset rather than as a complication.

Put the underlying mortgage in the marketing. Low building debt is a real underwriting advantage and most sellers never mention it.

Emphasize the policy stack. Pets, a liberal sublet policy, pied-à-terre, parents buying, gifting and guarantors is a broad permission set for a prewar Upper West Side cooperative. Name each policy in the listing.

Price the apartment, not the building. With combination units and irregular light-court layouts, a building-average number will underprice a good apartment and overprice a compromised one.

If you're considering The Powellton, also evaluate:

• 215 West 98th Street (The Gramont) — the closest structural analogue in the neighborhood: a 1911 prewar building organized as a condop, with the residential unit held by a cooperative corporation and the commercial units held separately
• 240 West 98th Street (The Sabrina) — on the same tax block but a different lot and a genuinely different animal: a true condominium of 166 residences created by a 1923 prewar conversion, spanning two wings on one BBL and carrying its own transfer fee. Do not confuse the two
• 780 West End Avenue (The Terra Cotta) — also on this block, a 1912 building converted to condominium in 1988, and — unlike The Powellton — inside the Riverside–West End Historic District Extension II
• 311 West 97th Street — a 1901 cooperative on the same street; the closest peer by vintage and tenure
• 760 West End Avenue — a 1926 cooperative converted from rental in 1982; the larger prewar co-op alternative on the block
• 255 West 98th Street — a 1913 cooperative converted in 1984; comparable vintage, conventional co-op structure
• 305 West 98th Street — an early-1900s cooperative converted in 1981; the West End Avenue alternative
• 12 West 96th Street — a 1930 cooperative of 69 apartments converted in 1970; the postwar-conversion comparison
• 150 West 95th Street — a 1925 cooperative a few blocks south; similar scale, different corridor
• 15 West 96th Street — a 21-residence new-construction condominium delivered in 2024; the modern-condominium alternative in the same submarket, with entirely different economics
