650 40th Ave, San Francisco, CA 94121

The property at 650 40th Avenue is a two-unit, two-story multi-family residential building located in the Outer Richmond neighborhood, built in 1927 and currently owned by the Kimberly H Kim Living Trust. The building has undergone significant recent renovations, most notably in 2023-2024, including major improvements to both units such as the replacement of 300 square feet of siding, bathroom renovations, kitchen updates, and the installation of a roof-mounted solar PV system. Earlier improvements included re-roofing (August 2023), bamboo flooring installation (September 2023), and comprehensive electrical upgrades including circuit labeling and GFCI protection (March 2024).

The building has a history of addressing various compliance issues, including the removal of an illegal staircase and door modifications in 2024, correcting an unpermitted rear deck in 2017, and window/door replacements in 2018. Several plumbing and electrical permits have been issued and completed, indicating regular maintenance and upgrades to the building's systems. Of note are multiple sewage back-up incidents reported in 2023 (four occurrences in May alone), though these were all properly resolved according to PUC records.

The property has experienced some neighborhood issues as documented in 311 calls, including reports of abandoned vehicles and sidewalk defects, but these were exterior to the building itself. The extensive list of recent permits and improvements suggests active maintenance and upgrading of the property, with particular attention paid to modernizing systems and addressing historical compliance issues. The building's ownership has demonstrated an ongoing commitment to maintaining and upgrading the property, as evidenced by the significant investment in recent improvements totaling over $200,000 in 2023-2024 alone.
