731 42nd Ave, San Francisco, CA 94121

The two-unit residential building at 731 42nd Avenue in San Francisco's Outer Richmond neighborhood is a two-story flats and duplex structure built in 1945, currently owned by Hom Kingston. The property has undergone several significant improvements in recent years, with the most recent being a final inspection completed in August 2023 for previously approved work.

In 2023, an entry door replacement was completed at a cost of $7,424, and in 2020, three wood windows were upgraded to retrofit Fibrex windows at the rear of the building. A major electrical upgrade was also initiated in 2020, including the installation of a new 200-amp service with three meters and sub-panels, along with first-floor rewiring. In 2019, the building underwent a bathroom remodel, including both plumbing and electrical work, while earlier improvements included a complete reroofing in 2013 and structural work on the garage/porch area in 1989.

The property has experienced several maintenance and infrastructure issues, particularly related to sewer systems, with documented incidents of flooding in 2018 and sewage backup in 2009. There have been multiple parking-related incidents recorded through 311 calls, primarily regarding vehicles parking on sidewalks, though most of these complaints could not be validated upon officer inspection. While the building has had some historical plumbing and sewer challenges, recent years show significant investment in infrastructure improvements, including electrical upgrades, window replacements, and bathroom remodeling, suggesting ongoing maintenance and modernization efforts by the current ownership.
