Office Space for Lease in Upper East Side

Nobody built the Upper East Side for offices. It’s a residential neighborhood with five hospital systems bolted onto its eastern edge, so the space you can lease got squeezed into the leftovers: prewar towers on Madison, converted mansions off Park, medical suites near the campuses.

Available space asks about $53.76 a foot (CoStar, July 8, 2026). Manhattan’s average is $78.03 (Colliers, Q2 2026). For a firm whose clients already live on these blocks, that’s twenty-five dollars a foot saved and a commute that’s a walk.

Price isn’t the hard part up here. Finding anything is. Most deals close under 5,000 feet, there’s essentially no sublease market to raid (Metro Manhattan, Class A Office Rents by Neighborhood, August 2025), and cheap medical floors keep getting bought or gut-renovated out of existence.

Tenants who start early get the good floors. Everybody else takes what’s left.

Upper East Side Office Market Overview

The biggest players up here don’t rent. They buy. That one habit explains more about this market than any rent figure, and it’s the reason leasable inventory across Uptown Manhattan keeps getting thinner.

Manhattan’s having its best run in twenty years. Tenants signed 22.8 million feet in the first half of 2026, availability fell to 13.0%, the lowest since October 2020, and asking rents hit $78.03, up 5.7% on the year (Colliers, Q2 2026; The Real Deal).

None of that demand is coming for the Upper East Side. What’s changing up here is supply, and it only moves one direction.

Four Things Shaping the Market

• Institutions are buying the good buildings. Weill Cornell Medicine paid $510 million for Sotheby’s old headquarters at 1334 York in October 2025 (Commercial Observer). Bloomberg Philanthropies paid $560 million for 980 Madison, or $4,152 a foot. Sotheby’s owns the Breuer Building it moved into.
• Three trophy properties, three owner-occupiers. That square footage is off the board for good.
• New medical space reset the ceiling. Extell finished 1520 First Avenue in early 2026, a 425,000-foot tower and the first ground-up medical building here in decades. Ambulatory floors ask from $100 a foot. Tower floors ask $125 (Bisnow, January 2026).
• Mount Sinai’s real estate director told Bisnow she’s never negotiated $125 for a doctor’s office. That tells you who the building’s for: dermatology, plastics, cosmetic dentistry, concierge practices. The medical and healthcare guide covers the specialty in full.
• There’s no sublease escape hatch. Most submarkets give you a second market, where somebody dumps a built-out floor cheap to get out fast. The Upper East Side and the Upper West Side have basically none (Metro Manhattan, August 2025). If a sublet is the plan, look south.
• Madison Avenue came all the way back. Retail vacancy fell to 4.9% in the first half of 2026, the lowest in nearly twenty years, down from 16% in October 2020 (Madison Avenue BID via WWD). Over half those storefronts now carry rents above a million a year (REBNY, H1 2026).
• Brands that take the store want showroom and back-office space nearby, which quietly eats the floors above them. There’s more on the corridor in this piece on Madison Avenue retail.

What Upper East Side Office Space Actually Costs?

Ask five brokers what it costs and you’ll get five numbers, all of them defensible. A boutique floor in the low 60s asks $90. A suite over a bank branch on East 86th asks $45. Both quotes are real, and they’re eighteen blocks apart.

CoStar’s weighted average for available space says $53.76 (July 8, 2026). Check the fine print, though. That geography runs 65th to 110th Street, so it picks up cheap blocks above 96th and skips the expensive ones below 65th.

Listing services that only count buildings over 50,000 feet say $62 to $88 (CommercialCafe, 2026). Both numbers are honest. They’re just counting different buildings.

Metro Manhattan’s own listings land in between, and they’re probably the truest read available. A full floor at 801 Madison works out to roughly $75 a foot. A gallery floor at 43 East 67th runs $78. A terraced office at 60 East 66th comes in at $58.

Figure out how much room you need before touring anything. The office space calculator takes two minutes, and up here the gap between 1,800 feet and 3,000 feet is the gap between three options and a dozen.

Class A Office Space on the Upper East Side

Real Class A means a short list of towers between 59th and 65th, where the neighborhood runs into Midtown. Good floors ask $70 to $95. That stings until you price Park Avenue, where the average ask crossed $119 this spring.

Family offices, boutique investment shops, and lawyers who bill by relationship fill most of it. A nice lobby isn’t a class, though, and the difference shows up in the operating costs, so read what makes a building Class A, B, or C before the first tour.

One caveat on the marquee address. 750 Lexington, the 386,000-foot tower at 59th known as 1 International Plaza, hit a foreclosure auction in January 2026 with a $162 million minimum bid. Nobody bid. It went back to the lender (The Real Deal, January 2026).

That’s not automatically bad news. Lenders want occupancy and will write terms an owner won’t. Just get the ownership question answered in writing before spending money on legal fees.

Class B and Townhouse Floors

Strip out the towers and the institutions and you’re looking at the real market: prewar Class B and converted mansions, 800 to 6,000 feet, $50 to $70 on the good blocks. Plaster, moldings, tall windows, and an elevator older than your business.

Plenty of these floors feel like loft space once you’re inside. They just come with a residential front door instead of a freight entrance, which suits a therapist or a consulate a lot better than a lobby full of turnstiles.

Two buildings on the same block will quote numbers thirty percent apart, depending on how long the space has sat and how the landlord reads your credit. A lot of these owners are families, not REITs. They care who you are.

So tour them yourself, and don’t trust the average.

Cheaper Floors North of 79th Street

Along 86th Street and up through Yorkville and Carnegie Hill, floors run $40 to $60 and sit right on top of the 4, 5, 6 and the Q. Neighborhood dentists, tutoring outfits, accountants, small nonprofits, and therapy practices sign most of those leases.

Give up the Madison address and keep about twenty dollars a foot. On 2,500 feet that’s fifty grand a year. For a practice whose patients live within ten blocks, it isn’t a close call.

157 East 86th Street and the Agora Building at 1556 Third have been running this play for decades.

Check the electrical and HVAC before signing, though. A lot of this stock got wired for a different century, and nobody publishes a clean Class C average up here, so treat any single precise figure with suspicion.

Medical Office Space

This is the best medical market in New York City, and it isn’t close. Medical tenants signed 5.4 million feet across Manhattan between 2018 and 2024, and the Upper East Side beat every other submarket for patient care (CBRE). Uptown medical vacancy runs near 4% (JLL via Crain’s).

The campuses explain it. Weill Cornell, NewYork-Presbyterian, Memorial Sloan Kettering, Hospital for Special Surgery, and Lenox Hill all sit within a mile of each other, holding close to 19.5 million feet across sixty buildings that average twenty-plus years old (Newmark).

Referrals follow geography. So do leases.

Pricing splits hard. Built-out Class A medical runs $75 to $110. Older Class B suites go for $45 to $65. The new tower floors at 1520 First ask $125.

If patients pay out of pocket and the work is procedure-based, the top tier makes sense. Insurance-based primary care shouldn’t go near it, and should be shopping the older stock hard instead.

That older stock keeps shrinking, though. Manhattan owners pulled 2.1 million feet off the market for conversions last year (Colliers), a lot of it the exact tired discounted space that used to court medical tenants.

Free Rent and Build-Out Money

Free rent across Manhattan averaged 12.4 months in the first half of 2026, thinnest since 2019, with improvement money flat near $140 a foot (Colliers, Q2 2026). The concessions breakdown runs the math on what that does to effective rent.

Expect less than that up here, and it isn’t personal. No sublease pool means no pressure on direct rents, the buildings are small, and a landlord with four floors can’t hand out eighteen months free. Time and flexibility are what’s winnable.

Recent deals on a five or ten-year term have looked roughly like this, with shorter terms earning less and longer terms earning more:

Settle the build-out question before anyone talks numbers, because an allowance is only worth what it builds. Pick the term honestly, and the guide to three, five, and ten-year leases lays out the tradeoffs.

Then read the clauses that quietly cost money, which this piece on lease clauses covers in detail.

One thing catches small tenants up here constantly. Boutique landlords lean hard on personal guarantees, so know how the Good Guy Guarantee works and what a reasonable security deposit looks like before somebody slides four months across the table.

Who Leases Here, and Where You’ll Fit

This is a doctor-and-family-office town. Medicine owns the east side of the neighborhood, money and art own the west side, and the rest fills in around them: consulates, foundations, boutique law, design practices, and businesses that serve one of the wealthiest residential populations in the country.

The corridor usually picks the tenant up here, not the other way around. Find your row and the search shrinks before you tour anything.

Small team? This works better than the zip code suggests. Value floors north of 79th and townhouse suites in the 60s and 70s put a serious address within reach of five people, which is how it landed on the list of best NYC neighborhoods for small businesses.

Coming out of a shared desk? Read scaling from coworking to your own office first, because flex options up here are thin and the jump usually comes sooner than people plan for.

Want exposed brick and an open floor instead? That’s a Midtown South conversation. Start in Chelsea or SoHo, not here.

The Buildings

Nobody’s pitching amenity floors and golf simulators up here. The pitch is Central Park across the street, Museum Mile out the door, the best restaurants above 59th, and a client base that already lives within twenty blocks of the desk. Three tiers, roughly.

Boutique Class A, Lower Sixties and Madison and Park: attended lobbies, modern systems, park views up high, and floor plates small enough that a 6,000-foot tenant takes the whole floor and gets its name in the elevator.

Prewar Class B and townhouse, Lenox Hill and the side streets: high ceilings, real windows, restored lobbies, wood and plaster, and a front door that looks residential. Slower elevators and older mechanicals come with it.

Medical and value, hospital row and 86th Street: purpose-built clinical space at one end, honest and inexpensive floors at the other, most of them two minutes from the Lexington line.

Buildings Worth Knowing

• 1520 First Avenue: Extell’s 30-story, 425,000-foot medical tower between 79th and 80th, finished in early 2026, with Hospital for Special Surgery across the bottom eight floors. Column-free plates, 13 to 15-foot ceilings, oversized elevators, and the highest medical rents the city’s seen.
• 1334 York Avenue: Sotheby’s home from 1980 to 2025, now Weill Cornell’s after the $510 million sale. Ten stories, 420,000 feet, with Sotheby’s leasing back floors seven through ten. A research and clinical building now, not a leasing opportunity.
• 945 Madison Avenue, the Breuer Building: Marcel Breuer’s 1966 Brutalist landmark. Home to the Whitney, then the Met, then the Frick, and since November 2025 the global headquarters of Sotheby’s after a Herzog & de Meuron restoration. Landmarked inside and out in May 2025.
• 980 Madison Avenue: the old Parke-Bernet building, a full blockfront between 76th and 77th, bought by Bloomberg Philanthropies for $560 million in 2024. Gagosian, a tenant since 1987, gave up the upper floors and reopened at street level.
• 30 East 60th Street: boutique Class A at the Madison corner, a reliable source of small and midsize floors for finance, law, and medical tenants. See the building profile.
• 55 East 59th Street, Delmonico Plaza: a Class A tower on the Plaza District edge with efficient floors and heavy professional-services occupancy. See the building profile.
• 750 Lexington Avenue, 1 International Plaza: 28 stories and roughly 386,000 feet at 59th, built by the Cohen family in the 1980s and in lender hands since the January 2026 auction. Still one of the largest blocks of leasable Class A at this end of the neighborhood. See the building profile.
• 645 and 654 Madison Avenue: the two workhorse Madison office buildings in the low 60s, about 140,000 feet each, full of asset managers, family offices, and boutique advisory shops. 654 dates to 1927 and 645 to 1971, and they price accordingly.
• 157 East 86th Street and 1556 Third Avenue: the value end of the market. Small suites for medical, dental, education, and neighborhood professional tenants, sitting directly over the 86th Street subway complex.
• 801 Madison Avenue and 43 East 67th Street: boutique buildings with full floors in the 1,200 to 1,600-foot range. The kind of space a gallery, a showroom, or a single-practitioner office actually wants.

Who Owns What

Ownership matters more here than anywhere else in Manhattan, because there are two completely different kinds of landlord and they behave nothing alike. Guess wrong and you’ll burn a month chasing space that was never coming to market.

Institutions own the best buildings and sit in them. Weill Cornell at 1334 York. Bloomberg at 980 Madison. Sotheby’s at 945 Madison. Northwell across the Lenox Hill campus. None of that’s coming back.

Everything else belongs to families and single-asset owners who’ve held the same prewar building for three generations. They move slower, take it personally, and bend on terms in ways a REIT never would, as long as they like you.

Knowing which is which pays for itself. The rundown of the biggest landlords in NYC covers the wider field.

One neighborhood-wide item belongs in your diligence. Northwell’s $2 billion rebuild of Lenox Hill Hospital on East 77th won City Council approval in August 2025 at a trimmed 370-foot height, and neighbors sued in December 2025 to kill it (Crain’s). Construction runs about eight years.

Looking at space within a few blocks of 77th between Park and Lexington? Price that in. Eight years of jackhammers costs a practice real money with patients in the waiting room, and it’s real leverage on rent if you can live with it.

Getting There

Transit up here is good and one-dimensional. Everything runs north and south, nothing reaches a commuter rail station, and the crosstown trip is the one that’ll cost you. Settle it early with the commute calculator and everybody’s real home address.

The Second Avenue Subway changed more than it gets credit for. Since January 2017 the Q has run local under Second with stops at 72nd, 86th, and 96th, which pulled real pressure off the Lexington line and made the far east blocks leasable again.
