1438 Third Avenue, known as Maison East, is a 31-story condominium created from a 1985 rental tower through a 2006–2007 gut renovation and conversion by Broad Street Development. The conversion re-imagined the building from the ground floor up: a new lobby, new elevators, renovated corridors, full window replacement, and the combination of former rental apartments into larger, high-finish condominium homes.
Its appeal rests on modern condominium mechanics inside a well-located Upper East Side tower. Many units carry private balconies or terraces, apartments have in-unit washer/dryers and central air, and the condominium structure gives owners the financing, resale, and leasing flexibility that co-op buyers do not get. Sitting on Third Avenue between 81st and 82nd, the building is minutes from the Lexington Avenue 6 line and the Second Avenue Q, with the neighborhood's food halls and markets close at hand.

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.

Maison East trades on a price-per-square-foot basis, as condominiums do. Value here reflects the building's full-service operation, the modern systems delivered in the conversion — in-unit laundry, central air, updated finishes — private balcony or terrace access on many lines, and the leasing and financing flexibility of condominium ownership. That flexibility broadens demand to include both owner-occupants and investors.
Specific pricing turns on floor, exposure, layout, outdoor space, and finish level. Because per-square-foot values move with the market and vary line to line, buyers and sellers should ground expectations in current, unit-specific comparables rather than building-wide averages.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01510-7501) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk.

What to know if you’re buying
- Modern condo mechanics in a converted tower. In-unit laundry, central air, updated finishes, and condominium flexibility come standard here.
- Outdoor space on many lines. Private balconies and terraces are a meaningful draw and a pricing factor.
- Investor-friendly. The building's permissive leasing profile suits buyers who may want to rent the unit — confirm current rules at application.
- Quiet by design. Full window replacement in the conversion was marketed as producing an unusually quiet building for the avenue.
- Confirm parking and roof access. Public sources do not confirm an on-site garage or common roof deck; verify both directly at offer stage.
What to know if you’re selling
- Lead with the conversion quality. The 2006–2007 gut renovation and combined layouts distinguish Maison East from unrenovated 1980s stock.
- Market the flexibility. Condominium financing and leasing latitude widen your buyer pool versus nearby cooperatives.
- Feature outdoor space and finishes. Balconies, terraces, and updated kitchens and baths drive the pricing spread.
- Anchor to current comps. Price to recent per-square-foot trades in the building and immediate blocks.
