When is Open House New York weekend? What to know

Want to peek inside a power plant, a private club on Gramercy Park, or the last remaining glove factory in New York City?

Starting Oct. 18, Open House New York will present Open House New York Weekend (OHNY Weekend), an annual five-borough festival offering more than 200 ways for the public to explore, discover, and access their city.

Since 2003, the festival has invited hundreds of thousands of New Yorkers to gain a deeper understanding of the city through behind-the-scenes tours led by architects, engineers, designers, preservationists, historians, community advocates, curators, and more.

Most of the festival is free and open to the public—no advance registration or tickets are required. Due to safety and security, select OHNY Weekend sites will require tickets. These tickets are distributed via lottery, which runs through Oct. 4, and online registration, which opens Oct. 10. Get more info here.
