4137-4139 20th St, San Francisco, CA 94114

This two-unit residential building, located at 4137-4139 20th Street in the Eureka Valley/Dolores Heights neighborhood, is a two-story flats and duplex structure built in 1900 and currently owned by the Baker Jane Revocable Living Trust. The property has undergone several significant improvements in recent years, most notably a comprehensive compliance project in 2022 to address electrical code violations (CC-8560) as part of a condo conversion process, which included electrical system upgrades, new 80% efficient forced air furnaces, and water heater installations for both units, with a total cost of $75,000.

Additional recent improvements include a bathroom remodel in 2021 featuring new electrical fixtures, and the installation of an EV charger in early 2022. The building has a documented history of proper maintenance and upgrades, including two reroofing projects (2012 and 2000), a vertical addition in 1997, and a kitchen remodel in 1991.

The property has experienced some infrastructure issues in the surrounding area, particularly regarding sidewalk conditions in late 2021, though these were eventually resolved. There have been several parking-related complaints in the vicinity, with varying outcomes, but these are external to the building itself. The most recent inspections and permit work suggest active management of the property's maintenance and compliance requirements, with no current outstanding violations or safety concerns noted in the available records.
