At one time, the Basilica was a campus of buildings; the Queen Anne style Sister's Convent and Grammar School (1888–1889, Henry Burns) and the Romanesque Revival St. Alphonsus Hall (1898, Franz Joseph Untersee) administered by the parish. The church closed Mission Church High School in 1992, but a parochial elementary school still remains. The sale of these buildings at 80–100 Smith Street allowed much of the church to be restored. The sold buildings are currently planned to be used for 'Basilica Court,' a 229-unit residential complex, developed by Weston Associates, Inc. The Hall was the club headquarters for the St. Alphonsus Association founded in 1900. It was the preeminent social and athletic Catholic men's organization for nearly 50 years and its 1000-seat theatre held many community, political, and theatrical events.
