3906-3910 Mission St, San Francisco, CA 94112

The 10-unit, 3-story apartment building at 3906-3910 Mission Street in Bernal Heights, owned by T Lew Family LLC, has undergone several significant safety and infrastructure improvements since its construction in 1933. The property demonstrated serious safety concerns in 2008-2009, including unauthorized construction, fire safety violations, and egress obstructions that resulted in multiple fire code violations and inspections.

These issues were notably addressed through the completion of mandatory soft-story retrofitting in 2018 (Tier 4) and the establishment of a new fire alarm system with low-frequency sounders in 2022-2023 to meet current fire safety standards. More recent maintenance records show ongoing attention to building systems, including sewer pipe replacement work in 2019, bathroom renovations, and various electrical upgrades. The building has experienced two notable fire incidents, with one in 2021 requiring significant repairs to Apartment 1.

Recent history suggests improved maintenance practices, with the most recent fire safety complaints in 2023 being promptly resolved. The property has also addressed some infrastructure concerns through multiple 311 calls, including overgrown trees in 2023-2024 and a sewage backup issue in 2022. The building's current status shows no active violations, and most historical violations have been closed, indicating improved compliance with safety regulations and building codes.
