50 Crestline Dr, San Francisco, CA 94131

The 12-unit multi-family residential building at 50 Crestline Drive in Twin Peaks is owned by the Louis & Nancy Chan Living Trust and was constructed in 1963. The two-story apartment building has undergone several significant structural and maintenance improvements over the years, most notably completing a mandatory soft story seismic retrofit in 2018 that involved both first and second floors, along with below-grade levels, at a cost of $180,000.

Recent building concerns have emerged as of January 2024, with multiple active violations including issues related to building safety and code compliance such as fire escape maintenance, combustible storage, seismic strapping, and the need for exterior building component inspections (Section 604 compliance). The building has a history of fire safety system maintenance issues, with documented violations in 2005, 2007, 2016, and 2018 related to alarm systems and fire escape maintenance. Historical maintenance records show various improvements, including a roof replacement in 2017 ($10,000), installation of new siding in 2013 ($5,000), and previous roofing work in 1989 and 1996.

A notable complaint from 2012 involved mold and mildew issues around bedroom windows and sliding doors, though this was marked as not active shortly thereafter. The building has experienced recurring parking-related issues in the surrounding area, with multiple 311 calls regarding blocked driveways and sidewalk parking between 2019 and 2022, though these are external to the building structure itself. While the building has completed its mandatory soft story retrofit (classified as Tier 3, Work Complete, CFC Issued), the recent violations indicate ongoing maintenance and safety compliance challenges that require attention.
