1320 12th Ave, San Francisco, CA 94122

The Lee Family Trust property at 1320 12th Avenue is a two-unit, two-story multi-family residential building constructed in 1966 in San Francisco's Inner Sunset neighborhood. The building underwent significant window and door improvements in 2018, when the owners completed a $49,956 project to replace four street-visible patio doors and nine non-street facing windows with energy-efficient Andersen Fibrex materials, achieving a U-factor of 0.32, which indicates improved thermal performance.

This permitted renovation was properly documented and completed according to the city's planning records. More recent incidents related to the property include two notable municipal service calls.

In February 2019, there was a report of a collapsed sidewalk near the property, which was resolved through Department of Public Works intervention, though some unfinished flags around a utility vault cover remained. Most recently, in December 2024, a high-priority parking-related issue was reported to the MTA Sign Shop, though this case remains open as of the current date. While the building's documented history shows regular maintenance and upgrades, particularly regarding window and door functionality and energy efficiency, and addresses some public infrastructure concerns, it's important to note that the most recent incident relates to a parking matter rather than a building-specific issue.
