Four One Nine is a two-floor event studio in San Francisco that hosts corporate events for up to 250 guests and weddings for up to 150. It stands at 419 10th Street in the SoMa district and is rented as a configurable space: you bring your own caterer, bar service and production team.
Seminars and company events
The studio is set up for holiday parties, conferences, leadership meetings and off-sites, networking happy hours, fundraisers, galas, lecture series and brand partnerships. Four rental formats exist, depending on headcount. The full venue combines the Main Gallery, Middle Gallery, Library and Rooftop for 200 to 250 guests. Downstairs only covers the Main and Middle Galleries for up to 200. The Middle Gallery extended format adds the Library and Rooftop for 40 to 100 guests, and upstairs only offers the Library and Rooftop for 40 to 70.
Every rental carries a six-hour minimum and requires on-site managers during set-up, the event and strike. The space has an extensive list of A/V equipment, but no technician is provided, so organisers hire one from the studio's preferred vendor list.
Weddings and receptions
Weddings can use the whole studio, upstairs and downstairs, for up to 150 guests on any day of the week. A micro-wedding format is available Monday to Thursday for up to 40 guests in the upstairs space. The upstairs library has open windows suited to ceremonies, the covered rooftop with heaters holds seated meals, and the living wall and rooftop garden serve for photographs. Downstairs, the main studio can be set for a large seated dinner, and the gallery can host late-night dancing. Weddings require two on-site managers for the whole event.
Rooms and capacities
The main studio measures 3,300 square feet. Seated, the main gallery holds 150 guests, and 75 guests can stand upstairs. For corporate events with standing room, the main studio can reach 250 people. The first floor has the Main Gallery with an open kitchen, a Middle Gallery and a roll-up garage door. The second floor has the Library with a wet bar, plus access to the Roof Deck and the Rooftop Garden.
Catering
Four One Nine does not provide catering or bartending and sets no food and beverage minimum. It publishes a vendor guide, called the Little Black Book, listing caterers, bar services, furniture rental, florals and staging, party planners, DJs, art installation and handling, and A/V companies. Art installers outside that list need approval from the studio. Event insurance can be arranged through a partner, Event Helper.
Getting there
The studio is at 419 10th Street, San Francisco, CA 94103. Street parking is available at all hours. After 8:30 pm an hourly parking lot is open across the street, and valet can be arranged on request. There is no on-site storage, so vendors should take surplus items away after load-in.
