150-152 21st Ave, San Francisco, CA 94121

The Leung Family Trust owns this 4-unit, 2-story multi-family residential building located at 150-152 21st Avenue in the Lake-Presidio neighborhood. Built in 1912, the property has undergone several significant renovations and faced various maintenance challenges over the years. Most notably, from late 2022 through early 2023, substantial work was completed on the rear cottage, including a $150,000 remodel of the kitchen, bathroom, bedroom, and living room, along with foundational work, new plumbing, and electrical systems.

This followed a 2022 incident involving water damage repairs to Unit B's kitchen, bathroom, bedroom, living room, hallway, and storage room. The building's history includes some concerning events that merit attention. In 2005, there were complaints about illegal construction and sewer issues, though these were subsequently resolved.

More recent concerns include a 2024 sewage backup incident from the side sewer vent, though this was resolved through field work. The property has also experienced recurring issues with trees, including multiple incidents of damaged or fallen trees between 2017 and 2024, with one 1998 complaint about neighbor's rainwater leaking into the garage that remains listed as active. There have been several parking-related complaints and a pavement defect issue reported in 2018, all of which were resolved through normal channels.
