320 West 89th Street

Pelham clad the building in red-and-black brick laid in Flemish bond — a deliberate, decorative bond pattern rather than plain running brick — set over a limestone base and trim. It is a confident, well-detailed pre-war facade of its moment, more textured than the era's plainer apartment houses, and it sits comfortably among the period buildings on the block.

The 36 residences carry the pre-war virtues buyers come to the neighborhood for: hardwood floors, real room separation, generous closet space, and the ceiling heights and light that 1920s construction delivers, particularly in the upper-floor homes oriented toward the park and the monument. The unit mix runs from one- and two-bedroom layouts to larger combinations, with renovation levels varying apartment to apartment — some kitchens and baths fully modernized, others awaiting a buyer's hand.

320 West 89th Street operates as a well-maintained boutique cooperative with an attentive live-in superintendent, an elegant marble lobby, and an elevator, supported by a common laundry room, a bicycle room, and private storage included with the apartments. It is a self-service building rather than a doorman house — a structure that keeps maintenance efficient and is part of why the running costs here stay reasonable for the neighborhood.

On house rules, the building is welcoming where it counts. It is pet-friendly. Subletting is permitted on a case-by-case, board-governed basis, which keeps the building predominantly owner-occupied while giving shareholders flexibility when life requires it. As at any cooperative, purchases require board approval and a complete board package; prospective buyers should review the building's current financing posture and financial statements during diligence, both of which a serious buyer's representative will obtain before an offer.

Market read. Most recent trades (2024) cleared a median $927/sf across 1 sale. Median listing discount 1.3% 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 1-01250-0047) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. 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.

This is a board-approval cooperative, so plan for a full financial package and an interview. Because the building is a boutique self-service co-op, the value proposition is efficient carrying costs and pre-war character rather than hotel-style amenities — underwrite the maintenance and any assessment history against the 36-unit base, and confirm the building's reserve position in the financials.

The pet-friendly policy and case-by-case sublet posture make this a practical building for owner-occupants who may need flexibility down the road. For a buyer prioritizing a Riverside Park block, genuine pre-war rooms, and a smaller, neighborly shareholder body, the building rewards moving decisively when the right exposure and condition come available — choice inventory does not linger here.

The selling story is strong and specific: a Pelham pre-war on a coveted Riverside Park block, Flemish-bond brick, a live-in super, and pet-friendly, flexible house rules. Lead with the block and the park orientation — those are the qualities Upper West Side buyers search for first — and let condition do the rest.

Benchmark to renovated pre-war co-ops on the West End–to–Riverside blocks rather than to the broader Upper West Side average; an upper-floor, well-renovated home with park light should price at the top of that set. Coming to market with current financials in hand and the building's pet and sublet policies clearly stated removes friction for buyers and shortens the path to contract. Because turnover is modest, a sharp listing can capture buyers who have been waiting specifically for this block.
