779-781 6th Ave, San Francisco, CA 94118

The two-unit residential building at 779-781 6th Avenue in San Francisco's Inner Richmond district is a two-story flats and duplex structure built in 1924, currently owned by the Peirano Trust. The property underwent significant improvements in late 2012, with approximately $40,000 invested in a comprehensive bathroom and kitchen remodel in unit #779, including the replacement of cabinets, fixtures, bathtubs, tiles, countertops, and flooring.

This renovation was accompanied by electrical upgrades, including the addition of a house panel and meter, replacement of the fuse panel, and installation of new electrical outlets, as well as plumbing enhancements to modernize the bathroom and kitchen facilities. The building's infrastructure was further improved in early 2013 with sewer and water service upgrades, and additional electrical work was completed to support the renovations. The property has had multiple street space permits over the years, with the most recent set of permits issued in March 2018, indicating ongoing attention to street-related maintenance or improvements.

Some historical maintenance issues have been documented, including tree root-related sewer damage in 2008 and subsequent sewer service replacement, though these appear to have been resolved. More recent calls to 311 service relate to parking enforcement (2021), an overgrown tree (2020), and general cleaning (2010), with no major structural or safety concerns reported in recent years. The building's documented history suggests regular maintenance and upgrading of systems, with particular attention to modernization work completed during the 2012-2013 period.
