Off-Loop theater fans will need to update their records -- Theatre Building Chicago will now be known as Stage 773. The venerable three-theater space, home to many a transient company over the years, was sold on Friday, with Stage 773 (formerly Lukaba Productions) to become the primary tenant. The company is helmed by Brian Posen, who also runs the annual Chicago Sketch Comedy Festival (it'll celebrate its 10th anniversary in the space in January 2011).

The theater will still rent space to outside companies, according to Theatre in Chicago.
