A Private Pricing Opinion — what your apartment at 321 West 78th Street 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.
321 West 78th Street sits on one of the most charming residential blocks on the Upper West Side — a tree-lined townhouse street between West End Avenue and Riverside Drive, a short walk from Riverside Park. Built in 1925 and designed by Sommerfeld & Sass, the nine-story building is a graceful pre-war: red brick and limestone, with three-story pilasters rising to frame a canopied entrance. On a corridor where the celebrated full-service towers can feel imposing, 321 West 78th is the human-scaled alternative — a doorman pre-war on a quiet block, close to the river.
Built as a rental and converted to cooperative ownership in 1979, the building has been a share-and-board co-op for more than four decades. What makes it stand out among pre-wars is its accommodating house rules: it is pet-friendly, permits washer/dryers in apartments, and allows pied-à-terre purchases with board approval — a combination of flexibilities that many older West Side co-ops still resist, and one that materially widens the building's appeal.
Architecture and unit composition
The building is a well-mannered example of mid-1920s Upper West Side design. The red-brick façade is detailed with limestone, and the entrance is framed by pilasters that rise three stories and sheltered by a canopy — a dignified, restrained street presence that fits the townhouse block rather than overpowering it. At nine stories, the building keeps a low, neighborly profile that the side-street setting rewards.
The 56 apartments carry the pre-war virtues — solid room proportions, real foyers, good light — on a comfortable scale. Because the building permits washer/dryers, owners can install in-unit laundry, a convenience that older pre-wars frequently forbid and that buyers increasingly require. A renovation and alteration cycle in 1987 modernized common systems while preserving the building's character. The combination of pre-war bones and contemporary-friendly rules is the building's core value.
Building operations
321 West 78th Street is run as a full-service cooperative with a full-time doorman and a live-in superintendent. On-site amenities include a central laundry room, common storage, and bicycle storage. The house rules are notably accommodating: the building is pet-friendly, permits washer/dryers in apartments, and allows pied-à-terre purchases with board approval. On the financial side, the co-op permits financing up to 75% of the purchase price and charges a 2.5% flip tax at closing. That flexible posture — doorman service paired with modern-living rules — is unusual for a pre-war of this vintage and is a genuine differentiator on the corridor.

The latest available FISP filing classified the facade as Safe — no repairs were required at that inspection. Facade inspections run on a fixed five-year cycle; future inspection, repair, and any assessment decisions remain building-specific.
How to read this, and where it comes from
QEWI = Qualified Exterior Wall Inspector — the licensed engineer the city requires to sign the report (the independent expert, not the managing agent).
Penalties shown are amounts DOB assessed against filings on record across 2005–10 to 2025–30. 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.

What to know if you’re buying
The house rules are the differentiator. Pet-friendly, washer/dryers permitted, and pied-à-terre purchases allowed — for a 1925 co-op, that flexibility is rare and valuable. If in-unit laundry or a part-time home is a requirement, this building accommodates where many neighbors will not.
The terms are reasonable. Financing to 75% and a 2.5% flip tax are standard for a full-service pre-war; budget the flip tax as a seller cost at exit.
Buy for the block. The tree-lined townhouse setting between West End and Riverside, a short walk to Riverside Park, is a durable amenity in itself — quiet, central, and close to the river, with the doorman service that supports value.
What to know if you’re selling
Lead with the flexibility. A pet-, washer/dryer-, and pied-à-terre-friendly pre-war reaches buyers that stricter co-ops turn away — make those rules a headline, not a footnote.
Position the block and the service. The townhouse-street location near Riverside Park and the full-time doorman are the lifestyle case; pair them with the pre-war room proportions in the marketing.
Benchmark to flexible doorman pre-wars in the West 70s. Comparable analysis belongs against other full-service co-ops on the prized side streets between West End and Riverside, not against generic inventory — the rules and the location set the building's tier.

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.
