1108-1118 Lake St, San Francisco, CA 94118

The three-story, six-unit apartment building at 1108-1118 Lake Street, owned by Pan Tso-chien & Lee Shiu-mi, has undergone significant renovations since 2016, including the creation of an accessory dwelling unit (ADU) from unused storage space. The most critical recent work involved addressing safety concerns, with fire alarm system upgrades completed in 2020 to comply with San Francisco fire code requirements, and the building successfully completed its mandatory soft-story seismic retrofit. Between late 2020 and 2022, the property experienced several maintenance issues, including problems with water heater installation and venting that led to housing complaints about potential carbon monoxide hazards and subsequent mold concerns in 2020.

These issues were eventually resolved with proper vent installations and water heater updates in early 2021, though they resulted in violations that were not fully abated until August 2022. The building's maintenance history shows a pattern of addressing both structural and safety concerns, including dry rot repairs to stairs in 2021 and comprehensive sprinkler system modifications in 2018-2019. Earlier issues included rodent concerns in 2016 and various maintenance matters documented through 311 calls.

The property has undergone multiple permit renewals and modifications, with the owners actively maintaining compliance with building codes and requirements, as evidenced by the successful completion of the soft-story retrofit program, classified as Tier 3 with a Certificate of Final Completion issued. Recent 311 calls from 2024 primarily relate to street cleaning and structural maintenance, indicating ongoing property management attention to building systems and infrastructure. The building has experienced three fire incidents, though none resulted in civilian injuries, with two being false alarms and one related to an overpressure rupture.
