St. Patrick’s Church is located within San Francisco's downtown preservation district and is an individually designated historic resource, making it eligible as a preservation/transfer lot under the City’s TDR program, but it is also a useful case study of the complexity of the TDR program as it currently exists. The Mission Street corridor development illustrates both the potential and administrative complexity within a single block. Historic institutions such as St. Patrick’s Church, the Contemporary Jewish Museum, and neighboring preservation properties have participated in or benefited from the City’s TDR framework, helping channel development value toward the preservation of significant religious, cultural, and civic properties, but the City’s own TDR inventory documents 186,590 square feet of certified TDR originating from 748 Mission Street, while the Contemporary Jewish Museum project assembled and transferred 236,000 square feet of development rights to support multiple downtown developments. Despite the significance of these transactions, information about eligible properties, certified rights, transfer history, remaining inventory, and current market value remains fragmented across SF Planning files that are distributed across records that vary in completeness, format, and public accessibility, disparate legislative actions, and fragmented recorded documents that may not, standing alone, provide a complete transaction history.
