331-335 Willard St, San Francisco, CA 94118

The three-story, four-unit multi-family residential building at 331-335 Willard Street in the Lone Mountain neighborhood, owned by Wayne Y Lee & May S Chow 20, has undergone several significant improvements since its construction in 1910. Most notably, the building has completed mandatory seismic safety retrofit work as a designated Tier 3 soft-story building, installing blocking, shear walls, and anchors in the crawl space and basement at a cost of $30,000. Recent maintenance includes a completed reroofing project totaling $18,689 in March 2024.

The building has experienced some safety-related incidents in the past, most notably in 2004 when a routine inspection revealed multiple fire safety concerns including issues with smoke detectors, emergency exits, and fire extinguisher maintenance - all of which were abated by May 21, 2004. A 2016 complaint regarding unauthorized construction of an oversized shed in the rear yard was filed but ultimately marked as not active. The property has maintained compliance with major safety requirements since 2004, with no active building violations recorded in recent years. Infrastructure maintenance has been proactive, as evidenced by the recent reroofing project and completed soft-story retrofit.

The building's plumbing systems received an upgrade with a gas houseline extension in 2007. Recent 311 calls primarily relate to external issues such as street cleaning, parking violations, and tree maintenance, with three sewer-related flooding incidents reported on the street in January 2021. While there are several open service requests from 2023-2024, these generally relate to street maintenance and parking rather than building-specific issues. The attempted legalization of an additional dwelling unit (UDU) on the ground floor in 2018 was cancelled, and a related planning application was withdrawn.
