181-183 Laidley St, San Francisco, CA 94131

The three-story, two-unit multi-family residential building at 181-183 Laidley Street in Glen Park, owned by Peterkin Aaron E, has a significant history of permit and violation activity. Built in 1927, this flats & duplex building experienced a major unauthorized modification in 2006 when illegal dwelling units with kitchen and bathroom facilities were created in previously designated storage areas below street level. This triggered multiple violation complaints, with the most recent being active as of 2023, though earlier violations related to the unit conversion were officially abated in 2011.

The building has undergone several legitimate improvements over the years, including the installation of an EV charging station in 2014, solar panel systems in 2008, and various electrical and plumbing upgrades. More recently, the property has faced recurring sewer-related issues, with the most recent incidents reported in 2025 (sewage back-up discharge) and March 2024 (flooding). Previous infrastructure work has included reroofing (2005), staircase stucco work (2005), and foundation bolting (1992).

The building's permit history shows multiple attempts to address the 2006 violation, with several permits being issued and subsequently expiring between 2006 and 2012, including efforts to legalize the unauthorized modifications by removing kitchens and combining spaces with neighboring units. There is also documentation of a fire escape complaint in 2007, though this was marked as not active shortly thereafter. The property's maintenance record suggests ongoing attention to both improvements and persistent infrastructure challenges, particularly regarding sewer systems, as evidenced by multiple 311 calls related to sewer issues between 2019 and 2025.
