One of the last great single-screen houses in Los Angeles

Built in 1925 and restored with its original character intact, the Rialto pairs a full proscenium stage and raked auditorium with a mezzanine, balcony and a set of smaller rooms — so one building can hold a ceremony, a reception and a green room at once.

It's cared for by Mosaic, and our community gathers here on Sundays. The rest of the week it's yours. Tell us what you're planning and we'll work out the details together.

The spaces

Book the whole building or a single room. We'll help you match the space to the event when we talk.

AuditoriumThe Rialto auditorium

Rialto Auditorium

The main room — raked seating facing the stage, under the original proscenium and plaster detail. The heart of the building.

StageThe Rialto stage

Rialto Stage

A full proscenium stage with house sound and lighting, suited to live performance, ceremonies, panels and presentations.

MezzanineThe Rialto mezzanine

Rialto Mezzanine

The level above the lobby — an easy spot for receptions, registration, a bar or a quieter room alongside the main event.

BalconyThe Rialto balcony

Where your guests arrive — the original tilework, the stair up to the mezzanine, and room to gather before doors.

Below the house — useful as back-of-house, storage, crew space or a holding area during a shoot.

What happens here

A century-old theatre is a rare kind of room. These are the ones we host most often.

01

Weddings & receptions

Ceremony on the stage, reception on the mezzanine — one building, no moving your guests across town.

02

Concerts & performance

A real stage, a raked house and sightlines built for an audience, with sound and lighting already in place.

03

Film & photo shoots

Period architecture, a working theatre and back-of-house space — with crew areas and a basement to stage from.

04

Conferences & meetings

Main-stage sessions with breakout rooms upstairs and down, and a lobby that works for registration.

05

Corporate & offsites

A setting that isn't a hotel ballroom, for launches, all-hands, screenings and team days.

06

Community & non-profit

We keep room for neighbourhood and non-profit use. Tell us about the event and we'll talk it through.
