4717-4721 Mission St, San Francisco, CA 94112

The 11-unit apartment building at 4717-4721 Mission Street in the Excelsior neighborhood, owned by Leung Sze Yuen & Tracy Ho, has undergone several significant structural improvements since its construction in 1926. Most notably, the property completed mandatory soft-story retrofits in 2024, including both residential and commercial improvements with steel framing and shearwalls, though initial permits filed in 2018 for these works had expired. More recent permit activity in 2024 includes revisions to remove ADA components from previously approved work.

The building has a history of commercial space challenges, with multiple complaints about vacant storefronts in 2023, following a 2019 attempt to convert retail space into office/display/storage uses, which was eventually withdrawn. The property has undergone routine housing inspections between 2000-2011, with an active complaint from 2023 regarding vacant commercial spaces. Building violations from 2000 related to various safety issues, including combustible storage, electrical problems, and fire safety concerns, were all abated by July 2000.

Recent 311 reports (2023-2024) primarily relate to external maintenance issues such as graffiti, general street cleaning, and debris removal, though most of these have been resolved. While the building appears to be compliant with current soft-story requirements and recent permit revisions, the ongoing commercial vacancy situation may impact the property's overall viability. The most recent routine inspections and soft-story completion status suggest improved structural safety, though the withdrawal of the 2019 change of use application indicates challenges in repurposing the commercial space.
