405-423 Locust St, San Francisco, CA 94118

The property at 405-423 Locust Street is a 3-story, 6-unit multi-family residential building with 3 ground-floor commercial units, constructed in 1908 in the Presidio Heights neighborhood. The building has undergone significant improvements over the past two decades, most notably completing mandatory soft-story retrofits for both residential and commercial portions in 2017 at a cost of $90,000, demonstrating compliance with seismic safety requirements.

Recent renovations include multiple bathroom remodels (2010-2012), electrical system upgrades (including a 400-amp underground conversion in 2003), and the resolution of past building violations related to unauthorized unit conversions and commercial use of residential spaces in 2003-2009. The property has experienced recurring maintenance issues in recent years, particularly concerning tree-related damage to sidewalks (with two open cases in late 2023), while multiple 311 calls in 2023-2024 have reported issues with garbage management and street cleaning.

There were also some mechanical equipment noise complaints in late 2023. The building's fire alarm system has had three false alarms recorded, though no injuries were reported in any incidents. The most recent building inspections and permits suggest active management of the property and attention to infrastructure maintenance, with the soft-story retrofit completion being a significant safety upgrade.
