245 Parker Ave, San Francisco, CA 94118

245 Parker Avenue is a two-unit, two-story multi-family residential building located in the Lone Mountain neighborhood. Built in 1906 and classified as a Flats & Duplex structure, the property is currently owned by Frank H Yuen Tr. The building's maintenance history reveals several notable issues, with the most significant and recent concerns centered around plumbing systems.

In September 2024, the property experienced a sewage back-up discharge from the side sewer vent, followed by a customer callback to the Public Utilities Commission's Sewer Operations. The absence of a visible trap vent in front of the property was specifically noted in the inspection report. The building's exterior infrastructure has also faced challenges, with multiple reports of pavement defects in 2024, including one ongoing case from June 2024.

The property's historical records show two prior repair permits: a sidewalk repair from 2001 (expired) and a 1992 permit for ceiling repair and window changes. Other than these infrastructure issues, there have been relatively few incidents on record, including a 2018 environmental health service request that was transferred to the DPH Environmental Health Lead Program, and a 2014 building inspection case that required follow-up with a concrete testing engineer. While the building has reached its117th year of existence, the most pressing current concerns appear to be related to its plumbing systems and adjacent pavement conditions, though no immediate life-safety concerns are evident from the available data.
