National Comedy Theatre Rehearsal Studio operates a wheelchair-accessible practice room at 440 Upas St Suite 101 inside 92103. Outside theatre companies and improv cohorts book the Upas St room for table reads and blocking calls between bigger venue dates, including youth casts from Center Stage Children’s Theatre. The single-room footprint handles scene work, two-team match drills, and warm-up rotations on flexible hourly blocks. Movement-heavy rehearsals pair with floor work taught at BalletCenter Studios for dance and stage-combat sequences. Full multi-week rehearsal blocks for outside productions get scheduled here, complete with prop storage and load-in windows ahead of opening night.
