325 Lake St, San Francisco, CA 94118

The two-unit, two-story residential building at 325 Lake Street, owned by Brian A. and Betsy J. Brown, was constructed in 1907 and is classified as a flats and duplex structure.

The building's maintenance history shows several roofing projects from the 1990s, with one completed in 1997 and an earlier permit from 1995 that expired. More recently, in 2007, a sewer repair was conducted, involving the installation of new 4" sewer infrastructure and a 5" housetrap. The property has experienced significant sewer-related issues in 2024, with multiple incidents of sewage back-up discharges reported between January and September, affecting both side sewer vents and catch basin systems. The most recent sewage incident occurred in November 2024 and was marked as resolved.

Other infrastructure concerns include a lifted sidewalk due to tree roots in October 2024. The building's surroundings have faced various municipal service calls, including multiple instances of parking violations, though enforcement officers were typically unable to validate the reported violations. A notable incident involved an abandoned stolen motor scooter in April 2024, which was handled by SFPD. The property's plumbing challenges, particularly regarding the sewer system, represent the most significant pattern of issues in recent years, with more than five documented sewer incidents in 2024 alone.
