349-357 Pierce St, San Francisco, CA 94117

The property at 349-357 Pierce Street is a three-story, five-unit multi-family residential building with commercial space, constructed in 1885 and currently owned by Suzanne Mabardy. The building has undergone several significant improvements in recent years, most notably completing its mandatory soft-story retrofit in 2022-2023 (with a commercial portion costing $20,000 and residential portion $45,000), which included structural upgrades to improve seismic safety with moment frame and shear wall modifications. Recent maintenance work has focused on essential infrastructure updates, including the replacement of the building's water main line (2022), electrical system improvements (2022), and plumbing upgrades such as kitchen drain stack replacement and new sewage ejector installation (2020).

The building's heating and ventilation systems were also modernized in 2011-2012, including furnace and flue replacements, and earthquake valves were installed for all units in 2011. The property has experienced various maintenance and repair issues over its history, with more recent concerns primarily relating to water damage and ceiling leaks (2023), and an uncontained work complaint regarding exterior walls and windows (2024). Historical building violations from 2011 included multiple interior maintenance issues such as inadequate heating, lighting problems, and concerns about stairs, doors, windows, and floors, though these were all addressed and abated by January 2012.

The commercial portion of the building has experienced periodic vacancy, with recent complaints about an empty storefront (2023). Recent 311 calls (2024-2025) have primarily involved external issues such as parking enforcement requests and sidewalk cleaning matters. The building is currently in compliance with the Soft Story program requirements as a Tier 4 property with Certificate of Final Completion issued.
