527-529 18th Ave, San Francisco, CA 94121

The two-unit residential building at 527-529 18th Avenue in the Central Richmond neighborhood is a two-story flats and duplex structure built in 1921, currently owned by Chan Kok Min & Huang Elaine. The property has undergone several significant renovations over the past three decades, including a substantial improvement project in 1998 that added a family room, bedroom, and bathroom to the upper unit's basement, along with the installation of 18 new windows that are not visible from the street. Earlier updates include kitchen remodeling work in both 1990 and 1995, the latter involving comprehensive renovations of the kitchen and bathroom including cabinets and wall insulation.

A roofing project was completed in 2008 with an investment of $6,500. The building has experienced recurring sewer issues, with documented sewage backup incidents through the 4-inch sewer vent occurring in 2018, 2019, and most recently in November 2023, suggesting an ongoing plumbing infrastructure concern. The property has also faced periodic parking-related challenges, including multiple complaints about vehicles blocking driveways, with the most recent incidents occurring in 2020 and 2024.

While not directly related to the building's condition, these parking issues have been consistently addressed by enforcement agencies. Additional minor incidents include graffiti on a pole in 2019, which was not considered offensive. The building's maintenance history shows regular upkeep and improvements, though the recurring sewer issues warrant attention based on their frequency and recent occurrence.
