A Private Pricing Opinion — what your apartment at 929 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.
929 Park Avenue is a quietly distinguished pre-war cooperative carrying a notable architectural signature: it was designed by George and Edward Blum, the brothers whose ornamented apartment houses are among the most decoratively inventive of early-twentieth-century New York. Built in 1913 and converted to a co-op in 1959 — early, as Park Avenue conversions go — it brings the Blums' hallmark terracotta detailing to a prime Upper East Side block between 80th and 81st Streets.
The combination is the appeal: a Park Avenue address, a full-time doorman, architectural pedigree, and a building scaled to 36 households rather than several hundred. For buyers who want the Park Avenue corridor with real pre-war character and an intimate community — and a clear, knowable cost structure — 929 Park sits in a desirable and well-defined niche.
Architecture and unit composition
The Blums' work is what distinguishes the building from its neighbors. The beige-brick façade is enlivened with elaborate, detailed terracotta decoration — the kind of inventive ornament that was the brothers' signature — and the canopied entrance is marked by a handsome decorative surround and period light sconces. It is a building that rewards looking up: the detailing carries through the elevations rather than stopping at the base.
Inside, the 36 residences across 12 stories follow the pre-war Park Avenue vocabulary — high ceilings, hardwood floors, gracious entry galleries, and the room proportions of a 1913 apartment house. The layouts run from comfortable one- and two-bedroom homes to larger classic apartments, the kind of stock that defines the corridor's enduring appeal.
Building operations
929 Park Avenue runs as a full-service cooperative. A full-time doorman staffs the canopied lobby and a live-in resident superintendent manages the building, with the service standard expected on Park Avenue. Residents have a central laundry room and private storage. The building is pet-friendly.
On cost structure, the building's policy is clearly defined: a 2.5% flip tax is paid by the buyer at purchase — a knowable, budgetable figure rather than an open question. As a cooperative, purchases require board package review and an interview, and financing, sublet, and pied-à-terre terms follow the building's proprietary lease and house rules; we review the current board posture and carrying costs with buyers during a transaction. The 36-shareholder scale keeps governance intimate and service personal.

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 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.

The retrade record
Lines that have traded more than once in the public record — the building’s appreciation arc, apartment by apartment.
Full closing history with price-per-square-foot over time, the complete retrade record, and every line that has traded.
Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01509-0071) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. 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
Budget for the building's defined costs up front: the 2.5% flip tax is the buyer's at closing, which is unusual (flip taxes more often fall on the seller) and should be modeled into the all-in acquisition number. Review the cooperative's financials and reserve fund, and confirm the exposures and original detailing of the specific apartment, since pre-war layouts vary line to line. Expect a board package and interview. Value the Blum architecture and the full-service operation, both of which support long-term desirability. The location — Park Avenue at 80th — puts the Met and Museum Mile, the 6 train at 77th Street, and Central Park all within a short walk.
What to know if you’re selling
Lead with the address and the architect. A Park Avenue cooperative with the Blums' distinctive terracotta detailing is a resonant, marketable combination, and the full-time doorman and pet-friendly policy round out the pitch. Be transparent about the buyer-paid 2.5% flip tax — well-advised buyers will price it in, and clarity speeds a deal. Foreground the pre-war proportions, exposures, and any preserved original detail. With a moderate unit count, pricing should reference both the building's own trade history and the broader Park Avenue pre-war market between the high 70s and low 80s.

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.
