350 East 72nd Street (Le Chambord)

The lot is 5,109 square feet — roughly fifty feet of East 72nd Street frontage — and the building takes 70,776 gross square feet out of it across twenty-two stories. That is a narrow tower, and the floor plans follow from it: two apartments per floor, A line and B line, on nearly every level.

The stack is legible from the assessment roll. Floor one carries a single residence alongside the lobby. Floors two through nineteen run in A/B pairs, except that three of them — the sixth, fourteenth and eighteenth — are carried as single full-floor residences of roughly 2,650 to 2,810 square feet. Above nineteen the building goes to duplexes: two spanning floors 20–21 and two spanning floors 22–23. There is no thirteenth floor, which is why a twenty-two-story building numbers its top duplexes to 23.

Sizes run from 1,049 square feet at the smallest to 2,808 at the largest, with the great bulk of the inventory clustered between 1,327 and 1,404 square feet. In practice that means a building whose typical residence is a well-proportioned two-bedroom, with a handful of genuine family-scale full-floor and duplex apartments at the top of the stack. The largest residence is about 2.1 times the median and about 2.7 times the smallest, so a building-average price per square foot tells a buyer little on its own; line-and-floor analysis is the only useful method.

The lot is an interior mid-block parcel with no corner and no protected exposures on either flank. Window openings are concentrated on the East 72nd Street elevation. Any specific residence should be walked with the question of which windows are lot-line windows and what could be built on either side, since neighboring low-rise parcels on this block are themselves developable.

Le Chambord runs as a full-service condominium at small scale: attended lobby with doorman and concierge coverage, a live-in superintendent, a bicycle room and private storage, per listing and management-sourced records. No fitness center is documented in the reviewed material. Assessment fields show zero retail, garage and other non-residential area, and the reviewed recorded schedule contains no separate commercial lot. Verify actual space use, parking access and revenue in current records rather than inferring them from those fields.

Thirty-six residences is a small denominator to spread a doorman-and-concierge payroll across, and that is the honest operating tension in a building of this size. The service level is real; so is the per-foot cost of funding it. Any buyer should read the current operating budget and the reserve position rather than reasoning from the service roster, and should ask specifically about the façade cycle — Department of Buildings records show repeated masonry and brick-veneer work on the lot across 2000, 2008, 2009, 2016 and 2022, including concrete patching of south-façade balconies at the twentieth and twenty-second floors.

Turnover is low. Roughly 131 unit deeds have been recorded across the building's thirty-six lots since 1988 — an average of under four per unit in thirty-eight years, and in most years only two to five apartments change hands. The assessment roll also records a foreign government among the owners, holding several residences, which is the kind of long-hold institutional ownership that keeps a small building's supply tight.

Ownership form: Condominium. Purchases close through the standard right-of-first-refusal mechanism rather than a cooperative board approval. Thirty to forty-five days is a typical closing estimate.

Pets: Permitted per listing records. Confirm weight and breed limits in the house rules.

Pied-à-terre, subletting, LLC, trust and foreign ownership: Leasing by owners is permitted with conditions; pied-à-terre, LLC, trust and foreign ownership are not documented; confirm them in the declaration, bylaws and house rules. Minimum lease terms should be confirmed with the managing agent.

Minimum down payment: Not documented in the records located for this page.

Flip tax: Not documented in the records located for this page. Confirm any resale capital contribution with the managing agent.

Real estate taxes: No exemption appears on the residential unit lots on any roll from FY2011 through FY2027. Check the specific unit's tax bill for any abatement and run True Monthly Carrying Cost analysis against the current bill.

Recent sales

Recent closings 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 $1,138/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 5.2% 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 1-01446-7501; each condominium apartment is its own tax lot). 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 from recorded condo declarations and offering plans.

The roll shows no exemption and no phase-out schedule. Confirm on the apartment's tax bill that no abatement applies. Include the actual tax bill alongside common charges, assessments and financing in the monthly calculation.

Verify the architect attribution yourself if it matters to you. We carry Costas Kondylis at Philip Birnbaum & Associates as an attribution from architectural records, not as a documented fact. No DOB filing and no LPC report supports it.

Read the budget before the amenity list. Thirty-six residences funding full-time doorman and concierge coverage is a small denominator. Ask for the operating budget, the reserve balance and the façade and Local Law 11 status.

Test the exposures. This is an interior mid-block lot with no corner. Establish which windows in a specific residence are lot-line windows.

Price within the tier. A 1,327-square-foot half-floor and a 2,808-square-foot full-floor are different products in the same building. Do not average them.
