Unlock the City
Forget the Mayor, Open House New York holds the keys to the city.Crains New York Business
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.
From the signature Open House New York Weekend festival to design-driven public programs and the dynamic Urban Systems infrastructure series, join us to take an inside look at how the city works.
Open City Benefit
The Open City Benefit is a celebration of the power of place and new possibilities for our city.
On May 18, the Open City Benefit brought together hundreds of New Yorkers for a festive evening at Powerhouse Arts—a 117-year-old power plant that has been transformed into a contemporary art center and fabrication space on the Gowanus Canal in Brooklyn.
Thank you to our community of supporters for making the 2023 Open City Benefit possible and supporting our work to promote broad, unparalleled access to the city.

I applaud OHNY’s leadership, staff, volunteers, and supporters for 20 wonderful years of celebrating the remarkable diversity, feats of engineering, and visionary people that define New York City.Mayor Eric Adams
Three epic days of exploration, access, and discovery
Rooftop gardens. Design studios. Historic houses. Infrastructure tours. And more!
In 2022, the 20th annual OHNY Weekend welcomed over 20,000 visitors into 300 places across the five boroughs, spanning 120 neighborhoods and nearly 100 zip codes. We introduced a brand new lottery system for ticketed locations and filled over 8,000 slots across the three day festival. And we cannot wait to work with our community of partners, volunteers, supporters, and participants for an even bigger and better festival on October 20-22, 2023.

Explore the profound transformations underway for public libraries in New York and across the nation in the latest installment of Urban Systems, a themed series investigating the forces that shape the city.
