Welcome to SAC/Union Reservations

The Student Activities Center and Stony Brook Union are home to more than 17,000 events each year. Our spaces are available for everything ranging from single meeting spaces to building-wide conferences.

  • Recognized student clubs and organizations should place reservations through their Student Activities Advisor.
  • All other event organizers may reserve space in either the Student Activities Center (SAC) or Stony Brook Union (SBU) through the Facilities Reservations Office.
  • If you are a vendor looking for getting a Vendor Permit, please click here.

Note Regarding Changes & Updates:

While we are happy to accommodate all reasonable requests, we ask that organizers try to follow two requests:

  • Place any requests which affect staffing at least one week prior the event
  • Make any final changes to a reservation no less than 3 days prior to the event

Abiding by these two requests will greatly assist us in ensuring your event is set up to your specifications and runs smoothly.

If you need to cancel or reschedule an event, this should be done at least 1 week prior to the scheduled program.

Cancellations and changes should be done in writing to the Reservations Office.
