70 Crestline Dr, San Francisco, CA 94131

The 14-unit, 2-story multi-family residential building at 70 Crestline Drive in Twin Peaks, owned by Giampaolo Boschetti, has undergone several significant safety and infrastructure improvements since its construction in 1965. Most notably, the building completed a mandatory soft-story retrofit in 2015 costing $250,000, and in 2023 underwent a major fire alarm system upgrade costing $42,200 to comply with current fire code requirements. Electrical system improvements have included adding compatible devices and low-frequency sounders in sleeping areas in 2022, as well as historical work on removing obsolete equipment in 2015.

The building has a documented history of roof issues, with complaints from the 1990s regarding leaks and mildew problems, though these appear to have been resolved. Recent building violations from 2000 resulted in corrections to fire safety and security systems, and while there have been periodic fire safety complaints (most recently in 2022), the majority were found to have no merit or were promptly corrected. Recent activity at the property has primarily involved routine inspections and maintenance, with the most recent building complaint filed in January 2023 still showing as active in the Housing Inspection Services system.

The property has been subject to various infrastructure proposals over the years, including multiple attempts at lot subdivision and additional construction, though most of these proposals have been withdrawn or marked as informational. A series of 311 calls from 2020-2024 primarily relate to external issues such as parking enforcement, tree maintenance, and graffiti removal, rather than building-specific concerns. The building's maintenance record shows regular upkeep including roof replacements in the early 1990s and various systems upgrades to maintain compliance with current building codes.
