327 21st Ave, San Francisco, CA 94121

Located in San Francisco's Central Richmond neighborhood, 327 21st Avenue is a two-unit, two-story multi-family residential building constructed in 1913, currently owned by the Amy Lynn Jang Living Trust. The property has seen several significant upgrades and maintenance work over the past few decades, most notably in recent years with the installation of Tesla battery storage systems in 2020, although some related electrical permits have expired. The building previously benefited from sustainable improvements, including a complete installation of 24 roof-mounted solar PV modules with 5000W inverter power in 2008.

Historical maintenance records show earlier improvements such as reroofing work completed in 1989 and the installation of aluminum windows in 1984. The building has experienced a few notable issues affecting resident experience and neighboring properties, though none in recent years. A roof leak was reported in 2004 that affected the neighboring property and was promptly addressed within a month, and in 2002 there was an incident involving unauthorized modifications to the garage door and utility systems that was resolved within a week.

The property has generated a series of parking-related complaints in recent years, particularly in 2019, with multiple reports of blocked driveways and sidewalk parking, though enforcement officers were often unable to locate the offending vehicles. More recent service requests from 2018 and 2024 have primarily concerned street cleaning and maintenance matters. While the building's permit and complaint history shows regular maintenance and occasional issues, there are no currently active violations or concerns that would significantly impact resident comfort or safety.
