445 Warren Dr, San Francisco, CA 94131

The four-story, 12-unit multi-family residential building at 445 Warren Drive in Forest Knolls, owned by 445 Warren LLC, has undergone several significant improvements and faced various maintenance challenges since its construction in 1960. Most notably, the building completed mandatory soft-story seismic retrofitting in 2020 (Tier 4 status, Work Complete, CFC Issued), which included moment frame relocations and cost $110,000.

Recent maintenance issues have included a December 2020 complaint about lack of running water and construction-related exhaust fumes, though these were addressed promptly. The building has undergone multiple roofing projects, with the most recent completed in 2016 at a cost of $32,000. Historically, the property has faced several infrastructure challenges, including water damage and mold issues in 2016 affecting units 4 and 8, and a notable maintenance complaint in 2011 regarding inadequate heating, garage ceiling leaks, rusted kitchen pipes, and garage security concerns.

Building violations have included concerns about gas leaks, fire escape certification, and heating system requirements, though all these issues were eventually resolved. The building has maintained active compliance with fire safety requirements, with recent fire complaints in 2022 regarding exit maintenance being corrected, and previous citations for street numbering in 2017 and 2018 being found to have no merit. While parking-related complaints have been frequent in recent years (2022-2024), these are primarily external issues not directly related to building maintenance or resident safety.
