350-352 20th Ave, San Francisco, CA 94121

The property at 350-352 20th Avenue in the Central Richmond neighborhood is a two-unit, two-story multi-family residential building constructed in 1923, currently owned by the Leona L Nakagawa Trust. The building has undergone several significant improvements, with the most substantial renovation occurring in late 2008, when the property underwent comprehensive updates including a kitchen remodel, bathroom renovations, and electrical system upgrades that added new appliances, fixtures, and safety features.

A noteworthy structural improvement was made in early 2010 with the installation of 28 feet of foundation underpinning at the southern property line, demonstrating attention to maintaining the building's structural integrity. Recent evidence of maintenance issues includes several waste management concerns in 2021-2024, though these appear to be more related to street conditions than direct building maintenance.

The building's location has experienced recurring issues with illegal parking (three documented incidents between 2019-2024) and occasional sidewalk cleanliness issues, as evidenced by multiple 311 calls for general cleaning needs and illegal postings. The earliest building improvement on record was from 1985, when aluminum windows were installed in existing frames, but this permit has since expired. The property's permit history suggests a relatively proactive approach to maintenance and improvement, particularly with the substantial renovations completed in 2008-2010, though more recent incidents primarily relate to street and parking conditions rather than the building itself.
