Augrented Insights Report

The 8-unit, 3-story multi-family residential building at 150 Portola Drive in Twin Peaks, constructed in 1963, has undergone several significant repairs and improvements in recent years, with particular attention to structural integrity and safety concerns. Most notably, the building completed a seismic soft-story retrofit in 2017 (Tier 3) at a cost of $80,000, followed by additional structural improvements in 2022 involving steel pipe column repairs.

Recent concerns have emerged regarding staircase stability and unauthorized construction work, with active complaints filed in late 2023 suggesting potential safety issues. The building experienced multiple maintenance challenges in 2015-2016, including elevator outages, water damage, and mold concerns, all of which were eventually resolved.

A new electric vehicle charger installation was completed in December 2023, demonstrating continued infrastructure improvement. Historical maintenance records show regular upkeep including reroofing projects in 1992 and 2007, siding replacement, and plumbing upgrades such as new floor drains installed in 2017. The property has maintained compliance with building codes, though there was one planning violation regarding a skylight installation in the 1970s that was eventually resolved.
