105 Lake St, San Francisco, CA 94118

The 12-unit apartment building at 105 Lake Street, owned by Grinsell Lake LLC, is a three-story structure built in 1927 that has undergone significant renovations over the past decade. Most recently, in June 2023, the building received a fire alarm system upgrade costing $39,002, following previous fire safety improvements including an April 2021 installation and a 2016 soft-story retrofit valued at $98,000. The property has seen substantial unit improvements, with eight of the twelve apartments receiving kitchen and bathroom remodels between 2015 and 2022, including units #1, #2, #4, #6, #7, #10, and #12, often involving electrical upgrades and new fixtures.

The building has had some concerning recent issues, particularly regarding heating systems. An active complaint filed in December 2024 alleges that Unit #12 has been without proper heat maintaining the required minimum of 70°F for over four years, potentially violating housing codes. Historical records show past concerns about lead paint and emergency egress, though these were marked as not active after 2003 and 2015 inspections.

The property has maintained regular fire safety inspections, with recent fire alarm system checks conducted in 2020, 2021, and 2022 showing "Condition Corrected" or "No Merit" findings. While most building improvements have been properly permitted and documented, there was one complaint in 2020 regarding unpermitted construction work, though this case is now inactive. The building's infrastructure maintenance includes a significant sewer lateral replacement in May 2022, further demonstrating ongoing investment in the property.
