1310 Clayton St, San Francisco, CA 94114

The three-story, 16-unit multi-family residential building at 1310 Clayton Street in Corona Heights, owned by Octagon Properties LLC and built in 1961, has experienced several significant infrastructure challenges in recent years. Most notably, there is currently an active sewage leak issue, with multiple complaints filed in late 2024 regarding overflowing sewer lines and raw sewage in the vicinity of the building and driveway, including an unresolved complaint as recent as January 2025. The building, which is classified as a "Tier 2" soft-story structure, completed its mandatory soft-story retrofit in 2016, along with a significant walkway reconstruction project that same year.

Other major improvements include a roof replacement in 2006 and the conversion of three carports into ADU units that was filed for in 2022 with an estimated cost of $460,000. The building has undergone various safety system upgrades, including a fire alarm system modification in 2021, though there have been multiple fire alarm-related complaints and violations between 2015 and 2024 that required correction. Plumbing issues have been a recurring theme, with the most recent waterline work completed in January 2024 and previous violations related to sewer infrastructure in 2023.

Historical records show past building maintenance activities including stair repairs (1996), code compliance upgrades (1987), and addressing dry rot issues (2003). The property has also experienced various maintenance challenges, as evidenced by multiple violations in 2003 related to lighting, stairs, floor coverings, and sanitation, though these were ultimately resolved by March 2003. Recent 311 calls from 2023-2025 indicate ongoing infrastructure and maintenance needs, including sidewalk defects, tree maintenance, and issues with garbage and debris.
