Our Lady of Guadalupe Church Hall in Chula Vista occupies the parish event complex at 337 Tremont Street, serving as the primary gathering and reception venue for the 1944-founded Catholic parish in the Otay district. The hall hosts quinceañera receptions, wedding banquets, and parish fundraisers catered by local providers such as Baja Tacos & Gourmet Catering for large-format community events. A commercial-grade kitchen built during the 2006 expansion allows on-site food preparation for parish fiestas, tamale sales, and the weekly community meals that have sustained the congregation since the 1960s. The Tremont Street campus also connects to the larger Otay-area parish tradition shared by Church of the Most Precious Blood, which originated from Our Lady of Guadalupe's own expansion in 1958. The hall spans approximately 3,200 square feet with a capacity of 200 seated guests, a raised stage for live music and performances, and a dedicated storage wing for parish event equipment.
