A Private Pricing Opinion — what your apartment at Le Trianon 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.

As cited in The Wall Street Journal★ 92 reviews on Google

Third Avenue above 79th Street is a corridor of 1970s and 1980s towers, and most of them are indistinguishable from one another: white brick or beige brick, flush to the lot line, a canopy and a door. Le Trianon is the one on this stretch that spent money on the ground. The building is set back behind a landscaped plaza, the entrance sits under a large marquee carried on concrete supports with a sculpted first-floor treatment behind it, and the lobby is entered one step down through revolving doors. That is a small amount of architecture, but on Third Avenue it is a differentiator, and forty years on it is still the reason the building photographs better than its neighbors.

The façade follows the same logic. Warm light-orange brick rather than the period's default white, balconies with red-brick returns rather than raw concrete, bay windows breaking the plane, and an angled roofline that gives the tower a silhouette from the south. Liebman Liebman Associates, the architects named in the offering plan, were working in the same 1980s Manhattan apartment-house market as the larger production firms, and this is a building that reads as having been designed rather than extruded.

The second thing that distinguishes Le Trianon is scale in the other direction: 24 stories but only about 62 apartments as offered, on a lot of 7,676 square feet. That is roughly two and a half to three apartments per floor. The building is a thin tower, not a slab, which means most apartments have more than one exposure, corner units are common rather than exceptional, and elevator traffic is light. It also means the denominator for fixed costs is small — a 60-unit building carrying doormen, a concierge desk, a fitness room, a playroom, a roof deck and a landscaped courtyard is spreading a full-service payroll across very few apartments. Common charges here should be evaluated against the operating budget, not against the amenity list.

The third thing is entirely a matter of documents, and concerns a charge to include in the closing calculation. Le Trianon has no flip tax. What it has instead is a reserve contribution, payable on every conveyance, equal to five months of the then-current common charges. It is disclosed in the association's audited financial statements, it is non-refundable, and should be requested explicitly rather than assuming a no-flip-tax description means there is no conveyance charge. Ask about the reserve contribution by name.

Architecture and unit composition

The tower rises 24 floors on a 77-by-102-foot lot on the Third Avenue blockfront, one lot north of the corner at East 81st Street. The front entrance provides direct access to Third Avenue through the plaza, per the offering plan; the building has no side-street address and no through-block frontage.

The reported 99,000 gross square feet spans 24 stories and 62 apartments as offered; those totals do not establish interior apartment sizes. The described inventory includes one- to three-bedroom homes, with duplexes in part of the stack and private terraces on upper units; confirm dimensions from individual plans. Balconies and bay windows appear on most lines. Under the offering plan, balconies and terraces are limited common elements irrevocably restricted to the units they serve, and every apartment is separately metered for electricity, which puts the electric bill on the owner rather than into common charges.

Combinations have reshaped the building meaningfully over four decades: the plan offered 62 units, the association's auditors counted 54 in occupancy at the end of 2019, and DOB filings on record show at least two significant combinations in the 2010s involving stacked apartments and new internal stairs. A buyer looking at an apartment here should not assume the floor plan matches the original Schedule A, and a buyer looking for a large apartment should understand that most of the large ones in this building were made rather than built.

Building operations

Le Trianon is a full-service condominium with union-represented staff, an attended lobby, and an amenity program — fitness room, storage, playroom, bicycle room, roof deck, landscaped courtyard — that is generous for sixty apartments. Annual common charges ran a little over $1.1 million in the most recent audited year on file, with payroll and employee benefits accounting for well over half of operating expense. That ratio is the building in a sentence: this is a staffed building carried by a small ownership base.

The capital history on file runs through a single, coherent cycle. In December 2015 the board declared a $1.1 million special assessment, billed over twenty-four months from March 2016 through February 2018, to fund lobby and hallway air conditioning, hallway renovations, lobby renovations, an intercom upgrade, and boiler replacement. Owners could pay in a lump sum at a three percent discount, and ten chose to. A further $200,000 assessment was declared in 2018 for chimney and mechanical work. The associated spending — hallways, boiler, chimney, gym, elevator, scaffold, lobby lighting, vacuum and sump pumps — runs through the 2018 and 2019 statements, which is the pattern of a building doing its deferred maintenance all at once.

That cycle left the balance sheet thin. At year-end 2019, the most recent audited statement on file, cash stood under $60,000 against roughly $1.1 million of annual common charges, with reserve cash under $50,000, and members' equity in deficit. That statement shows no association debt, and as a condominium the building has no cooperative-style underlying mortgage, so the funding tools in use were common charges, assessments, and delay; association borrowing is possible only where the bylaws permit it. Its auditors note the absence of the required disclosure on future major repairs; no reserve study is in our file, so ask whether one has been commissioned.

Those statements are several years old and do not establish today’s reserves or funding policy. The 2016–2019 assessment history is relevant, but current audited statements and capital plans are needed to determine how later work has been or will be funded. Ask for the two most recent years of audited financials, the current reserve balance, the Local Law 11 façade cycle status — this is a balcony building of the right age for slab and railing work — and whether any assessment is declared or contemplated.

One further item worth knowing: the association has a real estate tax certiorari proceeding on file against the City, carried on the balance sheet as a payable. Certiorari work is normal and generally beneficial to owners.

Policy framework

Ownership form: Condominium. Purchases close through a board right of first refusal rather than a cooperative approval.

Reserve contribution on transfer: Five months of the then-current common charges, non-refundable, due on conveyance, per the audited financial statements on file. This is the building's transfer charge. Confirm the current common-charge figure and compute it before you sign.

Pied-à-terre, subletting, LLC, trust and foreign ownership: Not documented; confirm in the declaration, bylaws and house rules. Minimum lease terms and any sublet fee should be confirmed with the managing agent.

Pets, financing minimums, and house rules: Not documented in the plan or in public records. Confirm in writing.

Electricity: Separately metered per unit under the offering plan; the fitness facility and storage room are usable by unit owners without additional charge.

Application and transaction fees

Fees below are from building management's published schedule, as of July 2026. They are shown as published, item by item; no total is added because the total depends on the transaction. Deposits are listed apart from nonrefundable charges.

Flip tax (transfer fee on resale)
Terms
There is no flip tax, but there is a transfer charge and it is substantial. Per the audited financial statements on file, upon conveyance of a unit a non-refundable reserve contribution equal to five months of the then-current common charges is due and payable. On a typical apartment here that is…

Facade safety — Local Law 11

Local Law 11 / FISP · last inspection 2020–25
Safe
What this means for you

The latest available FISP filing classified the facade as Safe — no repairs were required at that inspection. A filed Safe grade is not a guarantee of current condition: owners still maintain the facade and, where required, observe parapets each year. Future inspection timing (Local Law 49 of 2025 changed the cycle framework from October 1, 2026), repair and any assessment decisions remain building-specific.

How to read this, and where it comes from

QEWI = Qualified Exterior Wall Inspector — a licensed professional engineer or registered architect who meets DOB’s FISP qualifications and signs 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.

Recent sales

Le Trianon can be compared with condominiums in the Third Avenue and Second Avenue tower corridor between the 70s and the 90s, where a buyer has dozens of full-service 1970s-to-1990s options within a ten-minute walk. Differentiation in that market comes from four things, and this building has three of them.

Exposure and light are the first, and a thin 24-story tower with two or three apartments to a floor delivers them better than the slabs do — corner apartments and multiple exposures are the norm here, not the exception. Outdoor space is the second: balconies on most lines and terraces on some upper units, in a corridor where private outdoor space is scarce. Architecture is the third; the plaza setback, the marquee and the brick are a genuine and visible upgrade on the block.

The fourth factor cuts the other way. A sixty-unit building running a full staff and a full amenity list has a high fixed cost per apartment, and common charges here should be examined against the budget rather than against a rule of thumb. Combined with the five-month reserve contribution on transfer and no tax exemption on the roll (check each apartment's tax bill), the true carrying and transaction cost of ownership at Le Trianon is higher than the sticker suggests. That is not a reason to avoid the building; it is a reason to model it properly, because the offsetting facts — no scheduled abatement step-up, no underlying mortgage, and a large block of deferred maintenance already paid for — are genuinely favorable.

For sellers, the strongest arguments are the completed 2016–2019 capital program, the absence of any abatement burn-off waiting to surprise a buyer, and the light, air and outdoor space that the thin floor plate delivers.

Market read. Most recent trades (2026 to date) cleared a median $1,275/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 1.5% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

What to know if you’re buying

Budget the five-month reserve contribution. Ask for the complete conveyance-fee schedule, including the charge described as a reserve contribution. Compute it from the current common charges.

There is no abatement and there never was. Full taxes from the first closing in 1984. No abatement steps up later; taxes still move with assessments and rates.

Get the last two audited statements. The 2016–2019 statements report assessment-funded work and low year-end 2019 cash; they do not establish current reserve levels or the funding method for the next project. Ask what the reserve balance is today and what the Local Law 11 and balcony position is.

Assume the floor plan has changed. Combinations reduced the building from 62 apartments as offered to roughly 54 in occupancy. Verify what you are buying against the current certificate of occupancy and the board's alteration file, not against the original plan.

Search both addresses. 1437 Third Avenue and 1441 Third Avenue are the same tax lot; deeds and filings appear under both.

Do not confuse this with the other Third Avenue buildings. 1438 Third Avenue (Maison East) sits on block 1510 across the avenue and to the south; Étage (176 East 82nd Street) is also on block 1510 and is likewise addressed to Third Avenue; and The New Yorker (1474 Third Avenue) is on block 1512, was built in 1981 as a rental, and did not become a condominium until 2007. Three different blocks, three different histories, three different price bands. Confirm the block and lot before you comp.
