1640 Funston Ave, San Francisco, CA 94122

The property at 1640 Funston Avenue is a 2-unit multi-family residential building located in San Francisco's Inner Sunset neighborhood. Built in 1937, this two-story flats/duplex building has undergone several significant modifications and maintenance activities over the years. The most substantial historical issue occurred in 2007 when a housing inspection revealed unauthorized modifications, including unapproved wiring, plumbing, and a changed use from single-family to two-unit dwelling, resulting in a Notice of Violation.

This was resolved by February 2008 following permit applications to establish legal use and compliance. More recent infrastructure improvements include a sewer repair completed in 2019 and gas houseline extension work in 2011. The building has received regular maintenance attention, including reroofing in both 1990 and 2010.

The property's maintenance history shows ongoing attention to infrastructure, with several permits related to termite remediation in 1996 and various maintenance issues throughout the years. Recent municipal interaction primarily relates to external infrastructure matters, including street lighting, water systems, and tree maintenance, rather than building-specific issues. The building's history of 311 calls shows typical urban neighborhood concerns, including parking violations, street maintenance issues, and utility matters. Most recent service interactions have been resolved through normal municipal processes, indicating an active but generally routine level of building and neighborhood maintenance.
