40 Crestline Dr, San Francisco, CA 94131

The 12-unit, two-story multi-family residential building at 40 Crestline Drive in Twin Peaks, built in 1964, has undergone several significant improvements and maintenance work over the past decades. Most notably, the building successfully completed mandatory seismic retrofitting in 2017 (with a $60,000 cost) and a reroofing project in 2021 ($46,400), demonstrating compliance with current safety standards.

Other major renovations include the installation of vinyl siding and dual-glazed windows in 2004, and garage door improvements in 1995, though these are now considered quite dated. The building has a history of fire safety-related issues that were promptly addressed - in 2003, violations were noted regarding fire escape ladder maintenance and fire extinguisher recharging in common areas, but these were abated within a month. More recent fire safety matters include two complaints in 2022 regarding alarm systems and weeds, both of which were resolved.

The property has been documented as a "Tier 3" soft-story building, though this designation indicates that necessary seismic improvements have been completed. Recent activity at the property (2023-2024) has primarily consisted of routine municipal service calls related to external matters such as abandoned vehicle complaints, graffiti, and tree maintenance, rather than building-specific issues. While the building's age and history suggest ongoing maintenance requirements, the most pressing safety concerns appear to have been systematically addressed through various permit work and repairs.
