339 21st Ave, San Francisco, CA 94121

The three-unit, three-story multi-family residential building at 339 21st Avenue in the Central Richmond neighborhood, owned by Szeto Wing Kun Lau & Wai K, was constructed in 1913 and has undergone several significant improvements over the past decades. The most substantial recent renovation occurred in 2018-2019, involving comprehensive updates to the kitchen, two bathrooms, and the addition of washer/dryer facilities, with work properly permitted and costing $67,000.

Other notable maintenance includes a complete roof replacement in 2019 ($8,000) and previous repairs to address dry rot and stucco replacement in 1995. A building complaint was filed in July 2019 regarding unpermitted work, though this complaint is currently listed as not active. The property has experienced multiple street-level issues in recent years, with several 311 calls reporting debris and abandoned vehicles between 2019 and 2025, though these were primarily external to the building itself and were resolved through normal enforcement channels.

There was one building inspection request filed in March 2019 that was marked as resolved. The most recent incidents involve abandoned appliances (2025) and furniture (2024) near the property, both of which were addressed by Recology. While the building has received regular maintenance and upgrades, the concentration of street-level issues in the immediate vicinity suggests some ongoing challenges with neighborhood conditions, though these are not directly related to the building's internal systems or maintenance.
