150-152 Laidley St, San Francisco, CA 94131

The 4-unit multi-family residential building at 150-152 Laidley Street in Glen Park, owned by John K Liu and Crystal C Kwok, has a complex history since its construction in 1960. The property has undergone several significant modifications and faced multiple regulatory challenges, most notably during 2002-2003 when unauthorized modifications were discovered, including the illegal conversion of a community room into a fifth dwelling unit and various safety violations related to fire safety, electrical systems, and structural requirements.

These issues were addressed through a series of permits and repairs between 2002-2011, including electrical system upgrades to remove illegal wiring, compliance with plumbing inspection reports, and modifications to correct safety hazards. The building underwent a 2004 electrical system upgrade with an underground conversion to 200 amp service, and in 2011, various compliance issues were addressed through permits worth approximately $11,000.

More recent maintenance records from 2020-2024 show regular infrastructure upkeep, including multiple streetlight repairs in early 2021 and some parking-related issues, though these are external to the building itself. The property has maintained its legal status as a 4-unit building following the 2002-2003 violations, with completed permits for condo conversion on record, though these have been marked as "None fNone" and "Approved" without further developer details.
