405 Warren Dr, San Francisco, CA 94131

The 12-unit, 4-story apartment building at 405 Warren Drive in Forest Knolls, owned by Virginia Y Mac Gift Trust-2, was constructed in 1960 and has undergone several significant maintenance activities over the years, including reroofing projects in 1991 and 2002 costing approximately $10,120. The building has experienced multiple code violations and fire safety concerns, most notably a cluster of fire safety issues in July 2003, including problems with smoke enclosure door closers, obstructed fire escapes, and a malfunctioning fire escape drop ladder.

More recent violations were documented in March 2024, including concerns about weather proofing, dryer exhaust ducting, fire escape maintenance, egress obstructions, and a need for smoke/carbon compliance documentation. The building's fire safety history includes several incidents and false alarms, with documented responses to smoke scares, alarm activations, and a confined cooking fire, though fortunately, no civilian injuries have ever been reported.

A pattern of maintenance and safety issues emerges from the records, with violations of egress and fire escape requirements appearing in both 2003 and 2024, suggesting ongoing challenges in maintaining critical safety systems. Additionally, there have been various routine inspections, and while many complaints have been marked as "Condition Corrected," the recurrence of similar violations over time indicates persistent maintenance challenges. The property has also generated numerous parking-related complaints in recent years, particularly during 2024, suggesting ongoing issues with on-street parking management in the vicinity of the building.
