1435-1437 20th Ave, San Francisco, CA 94122

The two-unit residential building at 1435-1437 20th Avenue in San Francisco's Central Sunset neighborhood is a two-story duplex constructed in 1940, currently owned by Gregory G. Short.

The property has undergone several significant improvements over the past decade, including a substantial electrical upgrade in 2013 that installed a new 200-amp service and three subpanels, and a complete reroofing project in 2020 valued at $12,500. In 2011, the building addressed all Section I items from a structural and termite report (Fox Structural & Termite Report #13718), indicating attention to maintenance and building integrity. The property has experienced some infrastructure challenges, including a sewer vent issue in January 2021 that was promptly resolved.

The surrounding area has faced recurring issues with abandoned vehicles, with multiple reports between 2018-2019, though these were external to the building itself. Other neighborhood concerns, primarily street-related issues, have included instances of parking violations, graffiti, and debris, all of which were addressed through normal city enforcement channels and are not directly related to the building's condition or management. The building's permit history and prompt resolution of structural and electrical upgrades suggest regular maintenance and attention to building systems, with no significant safety concerns recorded in recent years.
