50-52 Auburn St, San Francisco, CA 94133

The two-unit residential building at 50-52 Auburn Street in the Nob Hill neighborhood is a two-story flats and duplex structure built in 1953, currently owned by Huang Jian Xian & Huang Hui. The property's documented history reveals several notable events, with the most serious being a building complaint filed in May 2013 regarding unauthorized demolition and reconstruction of a back porch.

While this complaint is listed as "Not Active," it suggests prior permitting violations related to construction work. The building has also experienced plumbing issues, including a sewer and house trap incident documented in 2009, and a sewage backup incident reported in January 2011, though the latter case was eventually resolved. The property has generated multiple 311 calls since 2018, primarily related to parking violations, with several reports of vehicles parking on the sidewalk in 2020 and 2022.

There have been two street cleaning-related incidents involving loose garbage reported to the Department of Public Works Operations in 2018 and 2011, both of which were resolved. A rent board-related inquiry was logged in May 2022, focusing on exemption filings and late fees, which was closed with a note indicating one exemption was on file. The building's permit history includes a street space permit issued in 2009 and a completed plumbing permit for sewer work from the same year.
