123 Lexington St, San Francisco, CA 94110

This two-unit residential building at 123 Lexington Street in the Inner Mission was constructed in 1907 and is currently owned by Mak Jin Ping Chen. The property has a documented history of significant safety and maintenance issues, most notably a serious fire incident in late 2015 that resulted in multiple housing code violations and triggered abatement proceedings.

The fire, which reportedly originated in an unpermitted kitchen, led to the initiation of violation notices in December 2015 and July 2016, with final resolution occurring in October 2016. Following the fire, substantial repairs were carried out in early 2016, including both electrical work (installation of 15 receptacles, 5 switches, and 2 panels) and drywall repairs totaling $6,000. The building's maintenance history also reveals earlier concerns, including a roof and ceiling repair requirement in 1987, and more recent issues involving waste management on the property's exterior, with multiple reports of debris and waste requiring cleanup through 311 calls in 2024.

There have been recurring concerns about illegal units on the property, with complaints filed in 2013 and 2015 mentioning unauthorized living spaces. The property has experienced various municipal service calls over the years, primarily related to street cleaning and sidewalk maintenance, with the most recent issues in 2024 involving human or animal waste incidents and interior noise complaints. The building is classified as a flats and duplex structure, containing two residential units across two stories.
