446 21st Ave, San Francisco, CA 94121

The property at 446 21st Avenue in the Central Richmond neighborhood is a two-unit, two-story multi-family residential building, constructed in 1988 following the demolition of a single-family dwelling and garage in May 1986. The building, owned by Jan Lam and Diana Wong Tang R, has undergone several notable improvements over the years, including a significant solar panel installation in October 2014 comprising 20 roof-mounted PV modules (255W each) with a total system rating of 5.1kW, and a roofing project in November 2012 that cost approximately $9,000.

The building's maintenance and compliance record appears generally positive, with no major safety violations or building code issues on record. However, there have been recurring parking-related incidents in the vicinity, with three documented cases of sidewalk parking between 2017 and 2024, including a resolved citation for driveway blocking in October 2021 involving a Subaru vehicle.

Street cleaning and maintenance issues have been relatively minor, with four reported cases between 2019 and 2020 concerning garbage and waste on or near the property, all of which were promptly resolved. The property's infrastructure appears to be modern, with the addition of solar power and timely roof maintenance, suggesting responsible ownership and maintenance practices.
