284-288 Bonview St, San Francisco, CA 94110

The property at 284-288 Bonview Street in Bernal Heights is a three-story, two-family residential building constructed in 1911, currently owned by Yeung Ka Lun. The building's legal status as a two-family dwelling was officially documented in February 2020 through an administrative permit, following a site visit and review of city records. Prior to this, a gas furnace replacement was performed in December 2019, though this permit has since expired.

The building has undergone minimal permitted work, with only three street space permits issued in May 2005 that were valued at $0. Of particular concern is the building's experience with sewer issues in the latter half of 2021. Between September and November 2021, there were multiple reported incidents of sewage backup through a 4-inch vent, resulting in at least seven sewer-related service calls to the PUC Sewer Operations department.

The most significant cluster of incidents occurred in October 2021, with four separate sewage backup reports. While these issues were eventually resolved through completed work orders, the frequency and nature of these incidents suggest a period of significant plumbing distress. The building underwent a gas furnace replacement in December 2019, but this permit was marked as expired, and there are no subsequent records of furnace or HVAC maintenance. The property has had minimal reported issues outside of the plumbing concerns, with only two other notable incidents in 2021 involving parking signage and litter receptacle enforcement.
