A Private Pricing Opinion — what your apartment at 1010 Third Avenue (166 East 61st Street) 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.
This building is a lesson in reading an address correctly. In the tax records it is "1010 Third Avenue" — the retail-and-garage base on the Third Avenue corner of East 60th Street, across from Bloomingdale's. In the residential market it is 166 East 61st Street, a full-service cooperative whose apartments almost all list, sell, and transact under that 61st Street address. The two are the same physical complex; the retail base and parking garage are separately owned and operated, while the co-op corporation — 166 E. 61 St. Corp. — owns the residential portion above. Getting the address right is the first step to finding the right comparables, because the resale data lives under 166 East 61st Street.
The location is the headline. Sitting directly across Third Avenue from Bloomingdale's, the building is at one of the busiest, most transit-rich corners on the Upper East Side, steps from the 59th Street subway complex and the crosstown routes to Midtown. It is a postwar full-service co-op — doorman, live-in super, garage — built in the Helmsley era of large, efficient apartment houses, and it trades as accessible Lenox Hill cooperative stock, with studios and one-bedrooms as its core inventory.
For buyers, the appeal is a doorman building in a prime-transit Lenox Hill location at co-op pricing, with a policy framework — pets, pieds-à-terre, and subletting all permitted — that is friendlier than the avenue co-ops to the north.
Architecture and unit composition
The complex is postwar red brick composed as two connected sections: a 9-story front building on East 61st Street, which holds the studios, joined to a 20-to-21-story tower on East 60th Street, which holds the larger apartments. Roughly 165 to 168 residences run from studios through one- and two-bedroom homes and combinations; sources differ modestly on the count and on the building's precise construction year, and the offering plan controls on any specific unit. Because the building is a cooperative, apartments are valued on a per-room basis rather than strictly per square foot.
The developer and architect attributions — Harry Helmsley and Horace Ginsbern — appear in the building's record but rest on limited public documentation; we carry them as likely rather than certain and confirm them in diligence.
Building operations
The building runs as a full-service cooperative: a 24-hour doorman, a live-in resident manager, a full-service parking garage at the base, central laundry, a bike room, private storage, and a landscaped courtyard. The garage and Third Avenue retail at the base are separately owned. The offering plan, house rules, and financial statements are held in The Roebling Research Library and available to clients during diligence.

The latest available filing classified the facade as SWARMP — Safe With A Repair and Maintenance Program: the engineer identified conditions requiring monitoring or repair, with repairs due by the deadline stated in the filing. The scope, timeline, and how the building funds the work are building-specific — we review the filings and board materials for you.
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 2025–30. 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.

What to know if you’re buying
Search under 166 East 61st Street. That is where the resale data and comparables live. Confirm you are underwriting the residential co-op, not the separately owned retail base.
Confirm the financing cap and transfer fee. Records point to roughly 75–80 percent financing and an existing but undocumented flip tax — verify both with the managing agent before offering. Run the Co-op Board Qualification Calculator.
The framework is flexible. Pets, pieds-à-terre, and subletting are permitted — friendlier than the northern avenue co-ops. Confirm current terms in writing at contract.
Studios and one-bedrooms are the currency. Use same-line comparables. Run the Co-op Affordability Calculator on the specific unit.
What to know if you’re selling
Lead with location. The Bloomingdale's corner and the transit access are the building's strongest assets — market them, and market the co-op under its 166 East 61st Street identity where buyers are searching.
State the flexibility. Pets, pieds-à-terre, and subletting permitted are selling points to this building's buyer pool; document the current terms from the Research Library for buyers' counsel.
Anchor to the line. Same-line history is the right comparable set; we maintain it.

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.
