165-167 Corbett Ave, San Francisco, CA 94114

The two-unit, two-story multi-family residential building at 165-167 Corbett Avenue in Corona Heights, owned by the Patricia E Frank Family Trust, has a recorded history dating back to its construction in 1900. The property has undergone several significant infrastructure updates, including an electrical service conversion to a 125A system with two meters in 2006, house trap replacement in 2021, and reconstruction of an exterior stairway to the rear yard in 1997.

More recent maintenance work includes a 2020 street space permit, though the associated costs were listed as $0. Historical issues documented in 1997-2000 highlighted electrical problems, including circuit trips and deteriorated wiring, along with heating system deficiencies and window/door issues, though these complaints were eventually abated. The building has experienced recurring sewer-related issues, with documented incidents in 2012, 2018, and 2021, including sewage backups and water main concerns.

There have also been various maintenance and infrastructure-related issues, such as a hanging cable box (2018), missing sewer vent cover (2016), and multiple instances of garbage management matters requiring attention (most recently in 2023). The property's maintenance history shows generally regular upkeep through the decades, with completed permits for reroofing in 1990 and other improvements, though some infrastructure concerns have persisted over time, particularly regarding plumbing systems and electrical components. While many historical complaints have been resolved, the age of the building and pattern of plumbing and electrical issues suggests these systems have required ongoing attention throughout the property's history.
