304-306 21st Ave, San Francisco, CA 94121

The Kwan Family Trust owns this two-unit, two-story multi-family residential building known as 304-306 21st Avenue, located in San Francisco's Central Richmond neighborhood. Built in 1920, this flats and duplex structure has undergone several notable maintenance events over its lifetime, with the most significant being a reroofing project completed in 2005 at a cost of $5,700.

Historical records show an earlier reroofing attempt in 1991, though this permit ultimately expired. The most recent incidents affecting the property occurred in 2024, with two specific cases of public space issues: one involving a sedan parked on the sidewalk in May, which resulted in enforcement action, and another in February relating to café furniture blocking the sidewalk, though this had 4 feet of clearance and involved removable furniture.

The building's vicinity has experienced recurring street cleanliness challenges, with multiple documented cases of loose garbage requiring city intervention between 2019 and 2024, including incidents on May 19, 2020, September 8, 2021, and September 8, 2023. There was also one instance of offensive graffiti reported in July 2021, which was subsequently addressed. While the building's basic infrastructure appears maintained through historical records, the surrounding area has experienced periodic cleanliness and public space management issues, as evidenced by the documented 311 calls.
