77 Park Avenue is a structural rarity twice over: a pre-war condominium in a corridor dominated by pre-war cooperatives, and one of the earliest condominium conversions ever recorded in Manhattan. The declaration converting the building was recorded in the New York County Register's office in March 1973 as Condominium Plan No. 9 — a single-digit plan number, from the era when the condominium form was still a novelty in New York housing. The offering plan on file in The Roebling Research Library, first offered March 22, 1973 by the sponsor 77 Park, Inc., priced the entire 106-unit building at $5,574,239 — less than the cost of a single large apartment in the building's peer set today.
The building itself is a 1924 Georgian Revival apartment house by Margon & Glaser, red-brick and disciplined, with the early-1920s luxury program intact where owners have preserved it: high ceilings, hardwood floors, and wood-burning fireplaces in a number of residences. The market consequence is the same scarcity argument that powers the few pre-war condos uptown: buyers who want pre-war proportions and detail with condominium transfer mechanics — no co-op board interview, broad eligibility for pieds-à-terre and flexible ownership structures — have very few options on lower Park Avenue, and this is the principal one. One caveat is written into the building's DNA: as an early conversion, its governing documents carry a board right of first refusal on sales and a board-consent requirement for leasing, a more co-op-flavored framework than modern condos — investors should understand current administration of those provisions before underwriting rental flexibility.
The building's history carries one genuinely press-covered episode. In 1936, Special Prosecutor Thomas E. Dewey's vice investigation reached an apartment here, in a prosecution whose client ledger — reported to include a major-league baseball team owner and prominent executives — made citywide news; the historian James Trager, in Park Avenue: Street of Dreams, judged that the case probably inspired Harold Robbins' 1955 novel 79 Park Avenue. Ninety years on, the anecdote survives as Murray Hill texture rather than market fact, but it is the rare lower-Park-Avenue building with a footnote in both legal and pulp-fiction history.
Position does the rest of the work. The building sits four blocks from Grand Central, between the Morgan Library and the 42nd Street corridor, in the quiet residential register of Park Avenue south of the viaduct — the same per-square-foot discount to the uptown Gold Coast that defines the Murray Hill thesis, here with condo mechanics attached.
Architecture and unit composition
The building rises on the east Park Avenue blockfront between 38th and 39th Streets — 14 floors per city records (brokerage records cite 15–16; verify against the floor plans) — with roughly 106 residences running from studios through three-bedrooms. Layout quality is classic Margon & Glaser-era 1920s work: defined foyers, high ceilings, crown moldings and beamed ceilings in preserved units, and the wood-burning fireplaces that anchor the building's marketing in every cycle. Renovation quality varies widely across 106 units and five decades of condo ownership — from preserved-original interiors to full gut renovations with high-end kitchens — so unit-level condition, light, and fireplace presence drive the spread far more than floor count. Avenue-facing units carry the Park Avenue address premium; rear and side exposures trade quieter and lower.
Building operations
Full-service in the pre-war sense: doorman, concierge, and a service tradition that has included attended elevators since the rental era — the 1973 offering plan on file budgeted seventeen staff, including five elevator operators — supported today by a landscaped roof deck with Empire State and Chrysler Building views, a fitness center, central laundry, bike room, and storage per brokerage records. There is no garage. The offering plan and by-laws are on file in The Roebling Research Library; current financial statements, the staffing model, and the administration of the lease-consent and right-of-first-refusal provisions should be confirmed with the managing agent during diligence.

What to know if you’re buying
The condo structure is the headline — with an early-condo asterisk. No board interview and condominium transfer mechanics, but the offering plan on file documents a board right of first refusal on sales and board consent for leasing — provisions closer to co-op practice than modern condo norms. Have your attorney confirm how the board currently administers both before you underwrite flexibility, especially for investor or pied-à-terre use.
Buy the unit, not the average. With 106 units across five decades of independent renovation, condition dispersion is wide. A preserved fireplace, a renovated kitchen, and an avenue exposure are each independently priced by this market; same-line history matters more than building-average $/sf.
The service model is the quiet differentiator. A doorman-concierge building with an attended-elevator tradition and a roof deck at Murray Hill pricing is a genuine scarcity. Weigh the payroll-driven common charges against amenity-building alternatives with the True Monthly Carrying Cost Calculator.
Verify the documents, not the folklore. The 1969 conversion date and 127-unit count that circulate in brokerage records are contradicted by the offering plan on file and city records (1973; 106 units). We provide the primary documents to your attorney — small discrepancies like these are exactly what diligence is for.
Price the corridor honestly. Grand Central proximity is the convenience and the caveat: weekday foot traffic on the avenue's commuter blocks is real. Spend time at the entrance at rush hour and on a weekend before deciding.
What to know if you’re selling
Lead with the structural scarcity. "Pre-war condominium, lower Park Avenue" is a three-word market thesis — there is almost no competing inventory that offers 1920s proportions, wood-burning fireplaces, and condo transfer mechanics in this corridor. Name it explicitly; your buyer's alternative is a co-op board.
Document the provenance. Margon & Glaser, 1924, Condominium Plan No. 9, the 1973 offering — the building's history is specific and verifiable, and we market it from the primary documents in the Research Library rather than listing-site boilerplate.
Condition and fireplaces drive the spread. Renovated units with working fireplaces and avenue light clear at meaningful premiums; original-condition interiors should be priced to the renovation math. Run the Renovation Cost Calculator against your asking strategy.
Mind the mansion-tax thresholds. Much of the building's two- and three-bedroom inventory trades around the $1 million and $2 million cliffs. Run the Mansion Tax Calculator at the intended ask and price around buyer psychology at the thresholds.
