7 Parsons St, San Francisco, CA 94118

The two-unit residential building at 7 Parsons Street in Lone Mountain, owned by the Chu Family Trust, is a 2-story flats and duplex structure constructed in 1906. The property has experienced recurring sewer-related issues, with eight documented sewage backup incidents between 2020 and early 2024, primarily involving 4-inch sewer vents.

These persistent sewer problems, most recently documented in January 2024, represent a significant ongoing infrastructure concern. The building's maintenance history shows some positive upgrades, including a 150-amp electrical service upgrade with two 100-amp panels and meter sockets installed in 2011, which was completed successfully.

The property has a history of regulatory scrutiny, with two building complaints filed in July 1998—one regarding an alleged illegal unit and another concerning possible unauthorized construction in the garage, though the illegal unit complaint was subsequently marked as "Not Active." In terms of recent tenant mobility, there was a documented buyout at 16 Parsons Street (though this address is not the same building) in August 2022 for $22,250 involving one tenant. The building's street space permit was issued in 2009, and there was a cleaning-related service call in August 2021 for loose garbage. The most pressing and persistent concern for residents appears to be the repeated sewer system problems, which have required multiple interventions by PUC Sewer Operations over the past several years.
