Ritz Tower (465 Park Avenue)

Roth and Hastings organized the tower in five diminishing stages. A limestone commercial base carries neo-classical ornament at the street; above it the shaft rises in setbacks that produce terraces at each transition and culminates in obelisks and a pyramidal crown. The setback terraces were a genuine innovation in 1926 and they remain the defining amenity of the upper stack.

The apartment plans reflect the apartment-hotel origin and seven decades of subsequent combination. Because the building was designed as suites rather than as full apartments, the floor plates were not laid out on a repeating line-by-line logic, and combinations over the cooperative era have produced a genuinely non-standard inventory. Department of Buildings filings carry a dwelling-unit count that has drifted between 133 and 140 across recent decades, which is the documentary trace of that process. The practical consequence is that no two apartments here are reliably comparable, and building-average pricing is close to meaningless.

The commercial base is a separate condominium unit. Its retail and office space — roughly 34,215 square feet by the Department of Finance record — is separately owned, separately taxed and separately capitalized. A buyer should understand where the boundary between the residential unit and the commercial unit falls, and what the declaration says about shared systems, façade responsibility and cost allocation between the two.

The building operates on a hotel-derived service model that survived the 1955 conversion. That is the building's principal differentiator among Park Avenue cooperatives and also its principal cost driver: staffed service at that level is expensive per apartment, and the maintenance charge should be evaluated on that basis rather than against a conventional prewar co-op benchmark.

Landmark designation adds a second operating layer. Because the Ritz Tower is individually designated, exterior alterations — including façade and parapet restoration, window replacement, terrace repairs and storefront changes — require LPC review, subject to specified maintenance exemptions. For this 41-story limestone-and-brick tower, the required scope, permit route and bids determine the Local Law 11 budget and schedule; designation alone does not establish a particular cost or delay. Buyers should ask for the current façade cycle status, the most recent engineer's report, and any assessment history tied to exterior work.

The condominium structure adds a third. The commercial unit's obligations under the declaration, and any shared-systems arrangements between the residential and commercial units, are the kind of thing that surfaces in a capital event rather than in a routine year. Both the cooperative's financial statements and the condominium declaration should be read together in diligence.

Ownership form: Cooperative shares and a proprietary lease, issued by The Ritz Tower, Inc., which in turn owns the residential unit of a two-unit condominium. Purchases require board approval and a board package. Expect a cooperative timeline, not a condominium one.

Financing, subletting, pied-à-terre, LLC and trust purchases: Governed by the cooperative's bylaws, house rules and board policy. These are not established in any document reviewed for this page, and they should not be assumed from the building type. Confirm the current financing ceiling, minimum down payment, sublet policy, pied-à-terre policy and flip tax with the managing agent before making an offer.

Landmark constraint: Individually designated. Exterior alterations require LPC review. Even without an interior designation, interior alterations requiring a DOB permit require LPC review; specified interior work without a DOB permit and qualifying maintenance may be exempt.

Real estate taxes: Class 2 cooperative assessment on the residential unit. No 421-a, J-51 or 485-x benefit applies. The small residual exemption in the roll is not a program abatement and should not be modeled as one.

Recent sales

Recent transfers at this building, from The Roebling Research Library. Prices are the transfer amounts recorded with the NYC Department of Finance; apartment-level detail is checked against the building’s own file in The Roebling Research Library before publishing.

Market read. Most recent trades (2026 to date) cleared a median $446/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 6.9% 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 1-01312-7502). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library. 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.

Know what you are buying. These are cooperative shares, not condominium units, notwithstanding the condominium number that appears in city data. The condominium exists to separate the commercial base from the residential tower. Board approval, board discretion and cooperative closing mechanics all apply.

Get the policy stack in writing. Financing ceiling, minimum down, sublet rules, pied-à-terre policy and flip tax are not established in the public record for this building. Ask the managing agent and confirm against the bylaws and house rules before you write an offer.

Read the condominium declaration alongside the co-op financials. The January 1991 declaration and its 1993 and 1997 amendments govern the relationship with the commercial unit — including façade, shared systems and cost allocation. That relationship is invisible in the cooperative's own documents.

Budget for landmark-constrained exterior work. Exterior alterations require LPC review, including non-visible work, subject to specified maintenance exemptions; permit type depends on scope and LPC rules. Ask for the façade cycle status and any assessment history.

No two apartments are alike. The apartment-hotel plan and seven decades of combinations mean line-to-line comparables mostly do not exist. Price the specific home.

Terraces are the scarce asset. The setback terraces are a product of the 1926 massing. They carry their own maintenance and LPC obligations, and they are the building's clearest premium.

Lead with the building's position in the record. First residential skyscraper in New York, tallest residential building in the city at completion, Emery Roth with Thomas Hastings, individually designated in 2002. That is a documented argument, not a marketing claim.

Explain the condop up front. Buyers and their attorneys will find the condominium number and be confused by it. Getting ahead of that with a clean explanation removes friction from the board package stage.

Sell the service model. The retained hotel-derived service is the reason the maintenance is what it is. Presented as a feature with its cost explained, it converts; discovered late, it becomes an objection.

Comparable selection matters more here than almost anywhere. Given the inventory's variability, pricing from a building average will misprice in one direction or the other. Argue from the specific plan.

If you're considering the Ritz Tower, also evaluate:

• The Sherry-Netherland — the closest structural peer in Manhattan: a 1927 landmark apartment-hotel tower with retained hotel services, operating as a cooperative
• The Pierre — 1930 apartment-hotel tower with a live hotel operation alongside cooperative apartments; the same hybrid problem in a different configuration
• Hampshire House — Central Park South apartment-hotel-era tower converted to cooperative ownership with a comparable service tradition
• The Carlyle — Upper East Side landmark tower with hotel and residential uses in one building; the nearest analogue for mixed-use complexity
• 475 Park Avenue — Park Avenue cooperative immediately north; the conventional prewar co-op alternative on the same avenue
• 470 Park Avenue — across the avenue; prewar cooperative at a different scale and service level
• 480 Park Avenue — full-service prewar Park Avenue cooperative; the direct policy comparison
• 500 Park Avenue — postwar condominium a few blocks north; the tenure and tax contrast
• 432 Park Avenue — the modern condominium tower two blocks south; the opposite end of the Park Avenue spectrum in every respect
• 110 East 57th Street — same corridor on 57th Street; the postwar alternative with different approval mechanics
