566 Pennsylvania Ave, San Francisco, CA 94107

The two-unit residential building at 566 Pennsylvania Avenue in Potrero Hill, owned by Drefke Shinbori Trust, was constructed in 1977 as a two-story flats and duplex structure. The property has undergone several notable maintenance and incident events over the past decade. In 2011, weather-related damage required repairs to the building's siding, while in 2016 a direct vent gas fireplace was installed.

The building has experienced multiple sewer-related issues, with documented incidents in January 2022 including a sewage backup and a missing side sewer vent cover, and a customer callback in March 2021 regarding sewer concerns. A water leak was repaired by PUC Water in January 2012. The property has also had two false alarm incidents: one for an alarm system activation and another for a carbon monoxide detector activation, neither resulting in any injuries or actual emergencies.

Additional records show various municipal interactions, including a 2019 PG&E work permit related to a gas leak investigation at a neighboring address, and two 2022 incidents involving street maintenance - a Christmas tree removal and the aforementioned sewer vent issue. The building's most recent permitted use change was an approved Cottage Food Operator application, allowing for a minor commercial use occupying less than one-third of the floor area with one non-resident employee. All reported issues have been resolved according to city records, though the frequency of sewer-related incidents can be noted as a consistent concern for the property.
