425 Warren Dr, San Francisco, CA 94131

The 12-unit apartment building at 425 Warren Drive in Forest Knolls, owned by Ng 2002 Revoc Lvg Tr, was constructed in 1960 and stands 4 stories tall. The property has undergone significant improvements in recent years, including a $35,000 fire alarm system upgrade in November 2023 to comply with SF Fire Code requirements, and previously completed soft-story seismic retrofit in 2018 (Tier 3) at a cost of $60,000.

The building has seen consistent modernization of individual units, with several recent renovations completed between 2018-2022, including comprehensive updates to Units #2, #8, #10, and #12 involving kitchen and bathroom remodels, new appliances, and electrical upgrades with costs ranging from $15,000 to $36,837 per unit. The property has experienced recurring parking enforcement issues, with multiple citations issued between 2023-2024 for sidewalk parking and driveway blocking, though these are outside the direct management of the building's maintenance.

Historical building violations from 2003 were resolved within a month, primarily concerning fire safety and security requirements, and there have been periodic fire safety inspections with instances of blocked exits and maintenance issues noted in 2011, 2016, and 2022, though all were subsequently corrected. The most recent routine housing inspection from 2018 was marked as not active, and the building's compliance with modern safety regulations is evidenced by the recent fire alarm system upgrade and completed soft-story retrofit.
