Open House New York Weekend is the one weekend a year the city unlocks the doors it keeps shut. In 2026 it runs Friday October 16 through Sunday October 18, the 24th time they've done it, with more than 300 destinations across all five boroughs opening for tours: new towers, water treatment plants, private collections, workshops, theaters, the kind of infrastructure you walk past every day without knowing what's inside.
It's free-form and it's enormous, which is exactly why people plan it badly. Here's how we'd do it, and how it works if you're staying up here in the East 60s.
The 2026 dates, and the two that matter more
The festival is October 16-18. But if there's a specific building you want inside of, the dates to put in your calendar are September 25 and October 2.
- September 18: members get early access to the lineup.
- September 25: the full lineup goes public, with every location, activity, date, and time.
- October 2: tickets are released for the sites that require them.
- October 15: the launch party, a fundraiser with food and drinks the night before.
- October 16-18: three days, five boroughs.
Most sites you can just show up to. The ones that need tickets need them because of space or security, and those are usually the ones everybody wants: the plants, the private homes, the places with a hard head count. They go fast. Set an alarm for October 2 rather than deciding on the 15th.
How to plan a day that isn't all subway
Pick one neighborhood per half day and walk it. That's the whole strategy. The mistake is building a list of six buildings you love and discovering they're in Red Hook, Mott Haven, Long Island City, and Midtown, at which point you spend the weekend underground and see two of them.
Build it the other way around. Open the lineup on September 25, filter to one area, find the three or four sites clustered there, and put them in geographic order with lunch in the middle. Add one ticketed anchor site if you got a ticket, then let the walk-ups fill in around it. Lines happen at the popular ones, so go to the biggest name first thing in the morning and save the quieter workshops and offices for the afternoon.
And read the hours. Not every site is open all three days. Plenty are Saturday only, some are one three-hour window, and the Friday sites tend to be the working buildings that can't host crowds on a weekday afternoon.
Doing it from East 62nd Street
Our block is a decent base for this because it sits on top of two useful lines. The F and Q at Lexington Av/63rd St get you across to Midtown and down through the East Side fast, and the 4, 5, 6 at 59th St-Lexington Av run straight down to Brooklyn Bridge and out to the Bronx. If your Sunday cluster is in Long Island City, the Roosevelt Island Tram boards at 59th and Second, two blocks from our door, and the ride over the East River is worth doing whether or not there's a building at the other end.
One good pattern for a three-day weekend: do Manhattan on foot Friday, take the train to one outer-borough cluster on Saturday, and keep Sunday local and slow. In past years the Manhattan lineup has included places like Rockefeller Center's Loft and Gardens, along with union training centers, foundations, and sign shops scattered across the boroughs, so "local and slow" still turns up things you'd never otherwise get into.
What to bring
ID, comfortable shoes, and a paper backup of your list. Some sites are working facilities and will check identification at the door. Cell service inside a mechanical plant or a basement archive is not a given, so screenshot your ticket confirmations before you leave.
Mid-October here is the good weather: mid-60s in the afternoon, cool enough by evening that you'll want a jacket. It's the best month to be walking this city, which is half the reason OHNY lands when it does.
Between stops
If your day starts or ends up here, the East 60s and 70s are an easy landing. Central Park is about eight minutes west through the quiet blocks, Museum Mile runs up Fifth from 82nd, and Sutton Place and the East River esplanade are ten minutes east if you want to sit down and look at the water instead of another lobby.
We like this weekend because it's the same instinct behind how we run this building. We chose everything in here ourselves, and OHNY is three days of other people explaining why they chose what they chose. Stay three nights or three weeks, it's your apartment, and there's a kitchen for the coffee you'll want before an early tour.
