800 48th Ave, San Francisco, CA 94121

The 7-unit, 2-story multi-family residential building at 800 48th Avenue in the Outer Richmond, owned by Warren Lee Trust, has experienced several significant events since its construction in 1961. Most notably, the building suffered a structural fire in Unit #4 on August 31, 2018, which caused moderate damage to the unit and smoke/water damage to hallways. This incident required substantial repairs, including electrical work, window replacement, and interior remodeling, completed at a cost of $120,000 in 2019.

The building is currently non-compliant with San Francisco's Mandatory Soft Story Retrofit Program (Tier 3), with an active violation filed in November 2022 regarding failure to complete required seismic safety work and associated monitoring fees. Recent maintenance issues have emerged, including water damage and mold/mildew problems reported in April 2023, and concerns about stuck windows affecting ventilation. The property has undergone several important improvements, including a soft-story retrofit permit issued in 2017 (though not completed), reroofing in 2012, and electrical system upgrades.

Multiple building violations from 2004-2007 were resolved, including issues with the central alarm system, rear garage door lock, and fire escape ladder maintenance. The building has experienced recurring fire alarm system malfunctions, as documented in fire incidents, though no civilian injuries have been reported in these cases. Recent 311 calls from late 2024 indicate various maintenance issues, including sewer problems and noise complaints, while multiple reports of garbage and debris issues have been documented, suggesting ongoing maintenance challenges. The property's historical records show a mix of resolved and active violations, particularly regarding seismic retrofitting requirements and water damage remediation.
