1045 Park Avenue is structurally distinguishing within the broader Carnegie Hill Park Avenue cooperative tradition for two specific reasons: the late 1983 cooperative conversion that places 1045 Park among the third wave of Park Avenue rental-to-cooperative conversions, and the small 26-apartment count that produces substantial floor-through apartment configurations across the building's 15 stories.
The 1923 Schwartz & Gross commission for Stahl Real Estate produced one of the firm's earlier Carnegie Hill Park Avenue commissions — predating the firm's mid-1920s Park Avenue body of work at 888 Park (1925–26), 910 Park (1924), 1070 Park (1928), 1095 Park (1930), and 1125 Park (1926). The architectural register at 1045 Park is Colonial Revival — a stylistic vocabulary structurally distinct from the firm's broader Italian Renaissance Park Avenue idiom. The brown-brick façade, the detailed cornice, the simple fenestration, and the restrained classical entrance together produce an architectural composition Architectural records describe as refined but not flamboyant — typical Schwartz & Gross pre-war at its most architecturally disciplined.
The 1983 cooperative conversion is the building's structurally defining institutional event. The conversion places 1045 Park among the "third-wave" Park Avenue conversions of the early 1980s — substantially after the broader 1950s-1970s post-war conversion wave that reshaped most of the corridor's rental inventory. The building remained under Stahl Real Estate ownership through the first several decades of the post-war conversion era; the 1983 conversion finally produced the cooperative structure under which the building has operated for more than four decades.
The 26-apartment scale produces substantial floor-through configurations and a structurally intimate cooperative culture. Within the broader Carnegie Hill corridor, 1045 Park sits among the smaller-scale pre-war cooperatives — comparable in apartment-count to 910 Park (28 apartments) and 935 Park (33 apartments) on the same broader Carnegie Hill block range.
The November 22, 2022 LPC presentation file documents the building's active position within the Park Avenue Historic District review framework — material for any prospective transaction that may involve exterior modifications.
Architecture and unit composition
The 26 cooperative apartments distribute across the building's 15 stories. The small unit count produces substantial floor-through configurations — a structural feature of the building meaningful to buyers prioritizing apartment scale and multi-exposure conditions.
Apartment-level features carry the pre-war Park Avenue layout discipline characteristic of 1923 Schwartz & Gross luxury construction: substantial ceiling heights, formal entry galleries, library-living combinations, formal dining configurations, and the staff-wing infrastructure characteristic of mid-1920s Park Avenue planning.
Recent transactions documented through Recorded activity includes the public marketing of Unit 1AB and the listing of Unit 10 at $6,250,000. Unit 5A recently sold for $1,810,000 (per public listing records).
Building operations
1045 Park operates as a full-service cooperative with full-time doorman. The 26-unit small scale keeps service ratios materially high relative to the broader pre-war Park Avenue cooperative tier. Specific staffing, amenity, and infrastructure details should be verified directly against current management documents.
The cooperative policy framework supports pet ownership subject to a 25-pound weight limit by Board approval — a structurally specific policy detail confirmed across public records and public records. Specific financing maximum, flip tax structure, pied-à-terre allowance, and sublet duration limits should be verified directly during due diligence.

Facade safety — Local Law 11
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.

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.
What to know if you’re buying
The 1983 cooperative conversion is structural. Among the third-wave Park Avenue conversions; the building's pre-1983 institutional history as a Stahl Real Estate rental holding produces a specific cooperative culture continuously refined for four decades.
The Schwartz & Gross architectural pedigree is real. Among the firm's earlier Carnegie Hill Park Avenue commissions; the Colonial Revival register is structurally distinct from the firm's broader Italian Renaissance Park Avenue idiom.
The 26-apartment small scale produces substantial floor-through configurations. Among the smaller-scale Carnegie Hill cooperatives; structurally distinct from the larger-scale 65-to-110-unit Carnegie Hill pre-war tier.
The pet policy is structurally specific. 25-pound weight limit by Board approval; common Carnegie Hill restriction but worth understanding at the start of any prospective transaction.
The Park Avenue Historic District protection applies. Designated LP-2547 by the NYC LPC on April 29, 2014; the November 2022 LPC presentation file documents active building-level review processes.
Verify operational specifics during due diligence. Specific board approval framework, financing structure, flip tax, sublet duration limits, current capital project pipeline, and the LL11 façade cycle on the 1923 vintage should be reviewed against current management documents.
Closing timelines are cooperative-standard. Plan for 6–10 weeks from contract through board approval to closing.
What to know if you’re selling
Marketing should emphasize the Schwartz & Gross architectural credential and the substantial floor-through apartment configurations. Both are structural identity features.
The late 1983 cooperative conversion is part of the building's institutional history. The Stahl Real Estate pre-conversion ownership history connects 1045 Park to the broader 1970s-1980s Park Avenue rental-to-cooperative conversion wave.
The 25-pound pet weight limit should be disclosed transparently. Sophisticated buyers will evaluate the policy framework; transparent positioning supports stronger transaction outcomes.
Pricing requires apartment-level comparable analysis on a 26-unit base. Thin transaction inventory means each closing carries meaningful weight in the building's reference pricing.
Closing timelines are cooperative-standard.
