A Private Pricing Opinion — what your apartment at The Blennerhasset would likely sell for today, what it costs to sell, and what you’d walk away with — reviewed personally against condition, exposures, renovation quality, and the competition actually on the market.
The Blennerhasset is a Beaux Arts apartment house designed by George F. Pelham for Max Liebeskind in 1903–04, during the development that preceded the Broadway subway's opening. Its double entrance portico and balustraded balcony distinguish a six-story building that now contains 24 cooperative residences.
Shared space extends beyond the lobby. A landscaped garden has seating and a basketball hoop, while an indoor playroom doubles as a residents' lounge. Those facilities give this relatively small association usable common rooms and outdoor space within the property.
Architecture and unit composition
The façade combines a rusticated stone base with brick and terra-cotta detailing above. Italian Renaissance and Baroque motifs appear within the Beaux Arts composition. Inside, marble and classical columns continue the formal treatment of the entrance.
The inventory includes two- and three-bedroom configurations, with larger homes as well as apartments in the roughly 600–900-square-foot range. Some living rooms face south across West 111th Street; rear rooms can face the garden. A front apartment's street exposure and a rear apartment's garden exposure offer different outlooks within the same building.
Windowed kitchens appear in the plans. Renovations have opened some kitchens toward living and dining areas, while other homes retain separate kitchens and more clearly divided rooms. High ceilings and wood floors recur, with the amount of preserved trim varying by apartment.
Building operations
An elevator serves the six floors. The building has superintendent service, central laundry and a video intercom, with bicycle storage complementing the shared recreational rooms. The garden includes both planted and paved areas, allowing seating and a basketball hoop to occupy the same outdoor space.
The cooperative also owns at least one apartment that it offers for rental. That is distinct from a shareholder subletting a privately owned home: the apartment remains an asset of the corporation. It adds another operating component to a property otherwise discussed primarily through shareholder resales.
The historic-district designation covers the building's exterior. The carved entrance and balcony are part of the architectural fabric that the cooperative maintains collectively, alongside the elevator and shared garden.

The latest available FISP filing classified the facade as Safe — no repairs were required at that inspection. A filed Safe grade is not a guarantee of current condition: owners still maintain the facade and, where required, observe parapets each year. Future inspection timing (Local Law 49 of 2025 changed the cycle framework from October 1, 2026), repair and any assessment decisions remain building-specific.
How to read this, and where it comes from
QEWI = Qualified Exterior Wall Inspector — a licensed professional engineer or registered architect who meets DOB’s FISP qualifications and signs the report (the independent expert, not the managing agent).
Penalties shown are amounts DOB assessed against filings on record across 2005–10 to 2020–25. The FISP dataset does not record whether they were paid, contested or remain open, so treat the figure as history rather than a current balance and confirm the building’s standing with the managing agent.

How to read the facts on this page. Items attributed to an offering plan describe the building as it was offered at that filing — unit mix, square footage, the amenity program as planned. They are not a statement about how the building operates today. Tax and compliance figures are sourced separately to current City records and carry their own dates. House rules, staffing and fee policy can change by board resolution without any public filing: treat every policy line here as a starting point for diligence and confirm it with the managing agent. Where this page compares one building or neighborhood to another, that is our analysis of the recorded record — it names the measure, the period and the sample it rests on, and it is an observation about medians rather than a prediction about any particular apartment.
