604-610 Shotwell St, San Francisco, CA 94110

The 8-unit multi-family residential building at 604-610 Shotwell Street in the Inner Mission, owned by Kan Kwok H & Shirley M, was built in 1900 and spans three stories. The property has undergone several significant improvements and faced various maintenance challenges over the years. Most recently, there have been notable upgrades including the conversion of a ground floor area into an ADU (2021, cost $102,000) and successful legalization of a previously unauthorized fourth-floor unit (2020, cost $129,159).

The building completed mandatory soft-story retrofit work in 2016 (cost $80,000) and addressed multiple safety concerns over the years, including rear stair repairs (2017) and various fire alarm system upgrades and maintenance. The building has encountered several maintenance and safety issues that have required attention, including multiple fire code violations, water intrusion problems, and plumbing system concerns. Significant historical issues include a cluster of plumbing and building violations in 2016 that were resolved by June of that year, and multiple fire system violations in 2006-2007 which were subsequently addressed.

The property has experienced occasional infrastructure problems, including electrical system upgrades in 2004 (400-amp service installation) and various storm-related moisture issues in the mid-2000s. While many historical violations have been resolved, there remains an active routine inspection case (2015) regarding certain building conditions, and a 2009 complaint about unauthorized roof work that is still recorded as active. Recent 311 calls from 2024 primarily relate to external issues such as illegal postings and street cleaning matters, rather than building-specific concerns.
