679 Guerrero St, San Francisco, CA 94110

The two-unit residential building at 679 Guerrero Street, located in the Mission Dolores neighborhood, is a two-story flats and duplex structure built in 1940 and currently owned by Joseph Bavaresco. The building underwent a significant electrical upgrade in May 2011, with the installation of a 200-amp system featuring two 100-amp panels and eight circuits, which was successfully completed.

Of particular note is a serious housing violation reported in October 2011 regarding an allegedly illegal studio apartment conversion in unit 681, which included concerns about substandard wiring, plumbing, heating, and cooking facilities posing health and fire hazards; this complaint was officially abated by January 2012. The property has experienced several maintenance and safety-related issues over the years, with the most recent being a garbage and debris incident in January 2025. There have been recurring issues with graffiti, including an offensive incident in October 2020 and a non-offensive case in March 2018.

The building has also been subject to various municipal service requests, including those related to parking (October 2022), temporary moving signs (November 2015), and tree maintenance concerns (November 2012) where a tree was reported to be damaging property. Other complaints, while not directly related to the building's condition, include reports of street cleanliness issues. The building's documented history shows a mix of typical urban maintenance issues along with the more serious 2011 housing violation, though there have been no recorded complaints regarding the illegal unit since January 2012.
