308-310 21st Ave, San Francisco, CA 94121

The two-unit multi-family residential building at 308-310 21st Avenue in the Central Richmond neighborhood is a two-story structure built in 1920 and currently owned by Martin Yee. The building has undergone several significant improvements and maintenance work over the past decades, with the most substantial renovation occurring in 2006 when a comprehensive interior remodeling project was completed, including bathroom and laundry room updates, electrical work, and hardwood floor refinishing, at a cost of $28,808. That same year, a 200-amp electrical service upgrade was also completed, indicating an important infrastructure modernization.

The roof has been maintained with two separate reroofing projects recorded, one in 2009 costing $7,750 and an earlier one in 1988, though the latter permit expired without completion confirmation. More recent building maintenance includes various street and sidewalk permits, with the latest issued in 2018. Plumbing improvements were made in 2008 with the installation of a waste line through the drain in front of the garage.

The property has had minimal issues reported through the 311 system, with only two street cleaning complaints noted - one in 2023 about glass that was investigated with no findings, and another in 2015 regarding loose garbage, which was resolved. A fire-related complaint was recorded in 2022 concerning weeds and grass, but this was determined to have no merit. The building's record shows regular maintenance and infrastructure upgrades over the years, with no significant safety or habitability concerns currently outstanding.
