337-341 Missouri St, San Francisco, CA 94107

The three-story multi-family residential building at 337-341 Missouri Street in Potrero Hill, owned by J Avery Mcginn 2010 Revoc T, was constructed in 1913 and contains three units. The property has undergone several significant structural and safety improvements over the years, most notably in the early 2000s when extensive foundation work was completed, including two separate foundation replacements in December 2004 (approximately 33 feet and 25 feet respectively), and garage area reinforcement work involving anchor bolts and plywood installation in January 2001. More recent improvements include a comprehensive electrical upgrade to unit #339 in November 2015, which involved installing a new 100-amp subpanel, smoke detectors, and various modern amenities, as well as a bathroom remodeling project in the same month worth $15,000 that included new lighting and ventilation features.

The building's maintenance history shows attention to safety and infrastructure needs, with completed projects including deck construction and repairs in 2000, reroofing in 1997, and porch support beam installation (though this permit expired). The property has undergone routine health and safety inspections in 2009 and 1999, with no active concerns indicated. Historical complaints from 1996 (illegal deck) and 1994 (possible illegal construction) appear to have been resolved.

Recent external infrastructure issues noted through 311 calls include a lifted sidewalk (2021), hazardous materials (2018), and pavement defects (2017), though these are street-related matters rather than building-specific concerns. A tree damage report from 2010 was also addressed, with details available in the notes section. The extensive foundation work completed in the early 2000s suggests a proactive approach to structural integrity, while the recent electrical and bathroom upgrades demonstrate ongoing modernization efforts. The building's permit history shows regular maintenance and improvements, with no recent building code violations or safety concerns reported through housing inspections.
