328 Corbett Ave, San Francisco, CA 94114

The two-unit residential building at 328 Corbett Avenue in Corona Heights, owned by James E. Packer, has a documented history dating back to its 1908 construction. The property has undergone several significant maintenance and improvement projects over the past decades, with the most recent being window replacements in 2017 ($3,500) and electrical upgrades in 2004 including an underground service conversion with two meters. Major works were performed in 2003, including a comprehensive roof replacement (both removal and installation of new materials at $13,500) and repairs to the porch structure ($7,500).

Earlier improvements include a kitchen, laundry room, and bathroom remodel completed in 1990. Of particular concern is the recent history of sewer-related issues, with multiple incidents reported between 2022 and 2023. Notable occurrences include flooding on the property in September 2022, a sewage backup in September 2023, and an odor incident in November 2023. The building also experienced plumbing code violations in 2011 regarding a missing house trap/fresh air inlet, though this was resolved within three months.

Infrastructure improvements were made in 2011 to address this violation, including the uncovering of a building vent sewer connection. Additional maintenance matters have been addressed over the years, including sidewalk repairs (2000) and various other plumbing and electrical updates. The property has generally been compliant with building codes, with most violations being promptly addressed and resolved. Recent 311 calls have primarily concerned sewer issues, with the most recent plumbing-related service requests indicating ongoing infrastructure challenges.
