100 Portola Dr, San Francisco, CA 94131

The 15-unit, 3-story multi-family residential building at 100 Portola Drive in Twin Peaks, owned by Artal Family LP, has undergone several significant improvements since its construction in 1975. Most notably, the building completed a mandatory soft-story retrofit in 2016 at a cost of $30,000, achieving Tier 2 compliance with a completed Certificate of Final Completion. In 2012, the building underwent a comprehensive window replacement project, installing 64 energy-efficient vinyl windows with a maximum U-factor of 0.40.

Earlier maintenance work included reroofing the building in 2004 for $11,000. The property has experienced minimal safety incidents, with only three fire-related responses recorded: a water/steam leak, a police matter, and a malfunctioning CO detector activation, none resulting in civilian injuries. However, in December 2019, the building was cited for multiple fire code violations related to storage in mechanical, electrical, and boiler rooms, as well as issues with building owner contact posting requirements - these violations have since been officially abated. The building's regulatory history shows one noteworthy complaint filed in 2008 regarding alleged height discrepancies, which was resolved the following day.

More recently, the building underwent a routine housing inspection in March 2023, with no active violations recorded. While there have been numerous 311 calls regarding the surrounding area between 2024 and 2025, primarily related to street cleaning and graffiti on public infrastructure, these external issues do not directly impact the building's condition or safety. The apartment complex appears to be generally well-maintained, with significant investments made in structural improvements and compliance with safety regulations over the years. Recent routine inspections and the completion of required safety retrofits indicate active management of the property's maintenance needs.
