229-231 Masonic Ave, San Francisco, CA 94118
The property at 229-231 Masonic Avenue is a two-unit, two-story multi-family residential building constructed in 1940, currently owned by Skm Sf2 Llc. The building has undergone several significant renovations over the past two decades, including a basement conversion in 2003 that added two bedrooms, a half bath, and laundry facilities at a cost of $20,000. A kitchen remodel was attempted in 2004-2005, though the initial permit expired, despite subsequent renewals.
Important infrastructure updates include furnace and flue pipe installations in 2015, sewer repairs in 2012, and electrical upgrades in 2004-2006. However, the building has experienced multiple concerning issues in recent years, including a complaint in September 2023 about loose tiles in the kitchen posing safety concerns with a child present, and past allegations in 2014 about unauthorized garage conversions and basement living quarters with inadequate safety features. The property has also had some maintenance needs addressed, such as stucco and dry rot repairs in 1998.
Recent activity around the property has been focused on graffiti removal, with multiple incidents reported between July and November 2024, though these were primarily affecting public infrastructure rather than the building itself. Two recent 311 calls for service regarding the building were logged in January 2025. While many historical permits suggest ongoing maintenance and upgrading of building systems, the presence of multiple complaints regarding unauthorized modifications and safety concerns raises questions about the thoroughness of renovation oversight. The most recent building complaint from September 2023 is particularly notable due to its recent nature and safety implications, though its current status is listed as "Not Active."
