331 21st Ave, San Francisco, CA 94121

The three-unit, three-story multi-family residential building at 331 21st Ave in the Central Richmond neighborhood was constructed in 1988, with earlier construction activity including demolition and the installation of a sprinkler system occurring in 1986-1987. The most significant recent building improvement was completed in October 2018, involving the installation of eight energy-efficient vinyl windows with a maximum U-factor of 0.32 or better, at a cost of $7,840.

An earlier roofing project from 2003 is noted in the records, though this permit has since expired. The property has experienced several maintenance and resident impact issues in recent years, with the most recent concern being an open pavement defect complaint filed in February 2024.

There have been recurring issues with street cleaning in late 2021, with multiple general cleaning requests for loose garbage being filed between November 12-17, though most of these were resolved with either no evidence found during inspection or being considered duplicate complaints. The building's immediate vicinity has experienced intermittent parking-related issues, with documented cases of blocked driveways in 2022 leading to citations, and two separate abandoned vehicle complaints in 2022 and 2019, both of which were resolved when the vehicles were no longer present at the time of inspection.
