A Private Pricing Opinion — what your apartment at 525 Park Avenue 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.
525 Park Avenue — historically known as The Parkside — is one of the oldest Park Avenue luxury apartment houses still in active residential use. The 1914 Schwartz & Gross construction predates the dense 1920s Park Avenue cooperative construction era that produced 720, 740, 770, and 778 Park by more than a decade. The building's Park Avenue / East 61st corner positioning is two blocks south of the Park Avenue / East 63rd–64th cluster and farther south than the iconic 740/720/770/778 Park Avenue tier-one peak.
The southern Lenox Hill / Plaza District boundary is structurally important. 525 Park sits at the seam where the Park Avenue residential corridor transitions to the Plaza District luxury hospitality cluster — within walking proximity to the Sherry-Netherland Hotel (1927), The Pierre (1930), The Plaza (1907), and the Plaza Athénée. These named buildings provide specific nearby examples of prewar architecture; no citywide concentration ranking is established here.
525 Park is unusual among Park Avenue's pre-war stock in two structural respects: (1) the 1914 vintage predates the 1920s building boom that produced the trophy peak, and (2) the building was converted to a condominium in 1989 rather than remaining a co-op. The building's documented terms permit pied-à-terre use and permit subletting with conditions; confirm the purchase approval process and current rules in the governing documents, since the ownership form alone does not settle them.
For buyers, 525 Park represents a particular tier of southern Lenox Hill Park Avenue inventory: Schwartz & Gross architectural pedigree, corner positioning, central Plaza District / Gold Coast border location, condominium structure, and pricing to compare using dated matched sales against the 720/740/770/778 Park Avenue buildings farther north.
Architecture and unit composition
The building's 1914 vintage and Park Avenue positioning suggest the pre-war luxury apartment-house idiom: limestone-clad lower floors, brick body above, classical detailing, formal canopied entrance, and apartment configurations reflecting the era's luxury Park Avenue conventions.
Pre-war signatures expected throughout the building:
- 10–11 foot ceilings in primary rooms
- Formal entry galleries
- Library-living combinations
- Primary suites with substantial closet infrastructure
- Service wings characteristic of 1920s luxury apartment design
- Wood-framed windows (specific configuration to be verified)
Park Avenue-facing apartments (west exposure) look across the Park Avenue median plantings. 61st Street-facing apartments (south exposure) have cross-street exposures looking toward Plaza District inventory.
Building operations
525 Park Avenue operates as a full-service pre-war condominium with full-time doorman, attended elevator, on-site superintendent, and private storage. Specific operational details — condominium board, managing agent, financing posture, any transfer or working-capital fees, leasing policy specifics, pied-à-terre allowance — should be confirmed directly with property management during due diligence.
The current declaration, bylaws and purchase application establish the condominium’s actual transfer-review requirements; neighboring co-op admission practices do not establish them.
Application and transaction fees

Common charges plus real estate taxes, combined into one monthly figure the way New York condominium listings show them. Add a mortgage payment for the monthly outlay. The split into common charges and taxes comes from the listings that also give the annual tax, a different sample, so the two lines need not add up exactly to the combined median; a tax abatement can hold taxes below the full amount until it expires. A summary of recorded sales and listings, not a current bill; charges change.

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.

Market read. Most recent trades (2025) cleared a median $2,316/sf (floor-adjusted) across 1 sale. 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 7.0% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

What to know if you’re buying
The southern Lenox Hill / Plaza District boundary positioning is structural. Buyers attentive to access to the Plaza District luxury hospitality corridor, Central Park's southeast corner, and Fifth Avenue should weight this geography heavily. The building is a prewar Park Avenue property at the East 61st Street corner.
Compare with specific Park Avenue peers. 525 Park should be compared using dated sales and apartment-specific adjustments with 720/740/770/778 Park Avenue farther north.
Confirm specific policies directly with management. Financing posture, any transfer or working-capital fees, leasing terms, pied-à-terre allowance, current capital expenditure pipeline, and architect/year-built attribution should be obtained directly during the contract review process.
Review the condominium’s actual transfer requirements. Obtain the current purchase application and any right-of-first-refusal provisions; no professional-accomplishment or primary-residence admission test is established here.
Review the applicable renovation requirements. Confirm the tax lot's exact LPC coverage and other exterior-work requirements; the district-membership assertion is not established here.
What to know if you’re selling
The Plaza District / Gold Coast boundary is a marketing asset. Listing copy should reference the corner Park Avenue / 61st positioning, proximity to the Sherry-Netherland and The Pierre, and the building's place within the broader pre-war Park Avenue residential corridor.
Pricing requires apartment-level comparable analysis. Floor altitude, exposure, configuration, and renovation history all matter substantially.
Closing timelines follow the condominium process, not a co-op board interview. Confirm the application and any right-of-first-refusal waiver timing 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.
