483-485 18th Ave, San Francisco, CA 94121

The two-unit residential building at 483-485 18th Avenue in San Francisco's Central Richmond neighborhood has a documented history spanning several decades, with both regular maintenance and some infrastructure issues. Built in 1916, this two-story flats and duplex structure is currently owned by Tom Wai Fong.

The building underwent an aluminum window installation in 1987, and more recently, there was a street space permit issued in 2008 for a nominal fee of $1. Since 2022, several street cleaning and maintenance issues have been reported near the building, including multiple instances of garbage and debris (with the most recent in October 2024), though these primarily relate to street conditions rather than building-specific concerns. A notable incident occurred in March 2022 involving a tree that was allegedly damaging property, but after inspection by an arborist, it was determined to pose no immediate safety risk and would be scheduled for pruning during the next maintenance cycle.

The building has experienced some infrastructure challenges, most significantly a sewage backup issue in May 2021 that was resolved by PUC Sewer Operations. The property has also been affected by parking-related incidents in June 2020, involving two separate illegal parking complaints for different vehicles, though one of these could not be validated by responding officers. While the building's age suggests regular maintenance is necessary, the documented permits and resolved service requests indicate basic habitability issues have been addressed, though the frequency of street cleaning-related complaints (with at least five separate incidents from 2022 to 2024) may suggest some ongoing challenges with waste management in the immediate vicinity.
