45 Crestline Dr, San Francisco, CA 94131

The two-story, seven-unit apartment building at 45 Crestline Drive in the Twin Peaks neighborhood, owned by Crestline Real Estate Invest, was constructed in 1965 and has undergone several significant upgrades to maintain safety and compliance with current codes. Most notably, the building completed a mandatory soft-story retrofit in 2015 that included the installation of new shear walls to meet seismic safety requirements, for which a Certificate of Final Completion was issued.

The property has received attention to various infrastructure components, including a main breakers replacement in 2020 (from Federal Pacific to UL-approved replacements), reroofing in 2013, and window upgrades in 2006 with the installation of energy-efficient vinyl windows. The building's history includes a cluster of violations in 2003 related to fire safety and building maintenance, including issues with the central alarm system, fire escape ladder, and stairs, all of which were resolved by February 2004.

More recent maintenance concerns have primarily involved exterior issues, as documented in 311 calls throughout 2023-2024, including multiple reports of blocked sidewalks due to vegetation, hazardous materials, and abandoned vehicles in the vicinity. The most recent routine inspection was conducted in January 2023 and is currently marked as active. The building's maintenance record suggests regular attention to major systems and infrastructure, though there have been some recurring issues with exterior maintenance and nearby abandoned vehicles, as evidenced by multiple 311 calls in recent months.
