Open House New York Weekend Unlocks 150+ Ways to Explore and Experience the City

We believe that our ability to share the city is fundamental to our civic life, our citizenship, and our humanity.

Since 2003, Open House New York Weekend has opened up more than 1,000 sites across the five boroughs for talks, tours, special events, and more, giving tens of thousands of visitors unparalleled access to the city’s most architecturally and culturally significant sites.

While the full festival lineup will be released in early October, you can expect a hybrid of virtual experiences, self-guided explorations, and in-person tours. Whether you join us from your couch or venture to a new neighborhood, OHNY Weekend aims to reconnect you to the city and remind all of us why we love New York.

Our Mission

Access the City

Open House New York promotes unparalleled access to the city—to the places, people, projects, systems and ideas that define New York and its future. Our programs, including talks and tours about how the city functions and who it serves and the annual OHNY Weekend festival, one of the nation’s largest, offer a citywide platform for education and exploration.

Since its founding in the wake of 9/11, when much of the city was closed off due to increased security, OHNY has advocated for openness as a defining principle of civic life. By providing access to thousands of places with architectural and cultural significance and an insider’s look at the city’s infrastructure and systems, both natural and manmade, OHNY fosters greater civic participation in the forces that shape the city.  Learn more.

“Forget the Mayor, Open House New York
holds the keys to the city.”

The Moving City

Transportation Infrastructures of New York
New York’s future depends on radically rethinking its transportation infrastructures for a new century. This series offered a yearlong series of tours, panel discussions, and other events to deepen and inform public understanding about the future of transportation and mobility in New York City.

Spaces of Justice

What should a 21st century justice system look like, and what kinds of architecture and infrastructure do we need to support it? This series examined the intersection of design and justice, and provided a platform for those who know the system from the inside—including judges, police and corrections officers, public health practitioners, housing advocates, activists, and people with lived experience of arrest and incarceration—to share their perspectives.

Our Commitment to an Open City

Open House New York has always stood for openness, accessibility and civic dialogue—the same values that make our democracy work.

Over the last year, Open House New York began the hard work of examining the realities of New York and more purposely advocating for a truly open city—one where streets, libraries, parks and other democratizing places are safe and accessible to all New Yorkers, regardless of skin color, religion, sexuality, or other marker of difference.
