300-310 28th Ave, San Francisco, CA 94121

The three-story, 6-unit apartment building at 300-310 28th Avenue in San Francisco's Central Richmond district is a 1923 wood-frame structure that has undergone several significant improvements over the years, particularly focusing on safety and structural integrity. Most notably, the building completed its mandatory soft-story retrofit program (Classified as Tier 3 with CFC Issued), which included a $20,000 seismic retrofit of the lower floor in 2015 to comply with San Francisco Building Code requirements. The building has experienced recurring maintenance and safety issues, with the most recent concerns primarily stemming from 2020-2021.

These included structural damage from water intrusion affecting bedroom windows, mold issues in multiple units, and stair repair violations that had to be addressed through building permits. The property has also undergone several infrastructure improvements, including a sewer line replacement in 2021, sewer repair in 2015, and a 200-amp electrical service upgrade in 2009. The building has a history of addressing key maintenance issues, including a rear stair repair project completed in 2020 and various plumbing improvements.

While the property had several violations noted between 2004 and 2020, including issues with self-closing door devices, egress obstruction, and security requirements, these were generally resolved by October 2021. Historical maintenance work has included window repairs, sill replacement, and general building upkeep, with the most recent work focusing on water intrusion issues and infrastructure upgrades. Recent 311 calls related to the property primarily concern external matters such as sidewalk maintenance and parking issues, rather than building-specific concerns. The building's ownership, under William & Patricia Mandel T, appears to have maintained compliance with major safety requirements, as evidenced by the completion of the soft-story retrofit program and other significant structural improvements.
