674-684 Corbett Ave, San Francisco, CA 94114

The three-story multi-family residential building at 674-684 Corbett Avenue, owned by Bang Kyoo Sung & Cho Mi Jun, was constructed in 1959 and contains 6 units. The property has undergone several significant improvements and faced various maintenance challenges over the years. Most recently, in May 2024, an active complaint was filed regarding safety hazards with the access stair railing, with reports of failing bars posing risks to residents.

The building completed a mandatory soft-story seismic retrofit in 2017-2019, demonstrating compliance with current safety standards. Earlier maintenance history shows recurring issues with water damage and mold, particularly in 2014, when multiple violations were recorded regarding interior surfaces, including the need for painting, addressing water damage, and mold remediation. A 2007 violation was resolved concerning an unpermitted wall furnace installation, and in that same year, there was a period without heating that required attention.

The building's maintenance record shows regular upkeep, including a deck renovation in 2011 to replace rotted wood and railings, and significant infrastructure improvements such as a 2004 electrical upgrade with underground conversion to 200-amp service. Historical maintenance includes addressing fire safety systems in 1983. The property has experienced some recurring issues with exterior cleanliness, as evidenced by multiple 311 calls in early 2025 regarding garbage and debris management around the property, though these are not directly related to the building's structural or habitability conditions. The soft-story retrofit work has been completed, with a Certificate of Final Completion issued, indicating successful compliance with this critical seismic safety requirement.
