Augrented Insights Report

The three-story, 12-unit apartment building at 3601-3623 23rd Street in Noe Valley, owned by Zanco Trust The, has undergone significant improvements and faced several challenges since its construction in 1905. Most notably, the building completed mandatory seismic retrofitting as a Tier 3 soft-story structure in 2019, with all related work being certified as complete. Recent improvements include a comprehensive fire safety upgrade in 2022, featuring the installation of a new manual fire alarm system ($42,000) and electrical updates, including new sub-panels.

The building has also received substantial unit improvements, with multiple unit renovations in 2022 including bathroom enlargements, kitchen remodels, and plumbing updates totaling over $100,000 in improvements. The property has experienced some concerning incidents and violations over its history, particularly during 2010-2012 when there were multiple housing code violations related to fire safety equipment, lead paint concerns, and various building repairs that needed attention. More recent complaints from 2022 raised issues about lead paint safety during construction work, along with noise complaints during renovation periods.

While these violations have been resolved, they indicate periods of maintenance and safety concerns. The building's maintenance history shows attention to structural and safety improvements, with records showing repair work on floor joists, stairs, and various building systems dating back to 2001. Three minor fire-related incidents were recorded, though none resulted in injuries or significant damage, and a recent inspection in April 2023 found no violations.
