148-150 Laguna St, San Francisco, CA 94102

The two-unit residential building at 148-150 Laguna Street in Hayes Valley, owned by the Tan Family Trust, was constructed in 1900 and has undergone several significant maintenance and improvement projects over the past three decades. Most recently, a kitchen and bathroom remodel was filed in July 2024, though an active complaint was filed in June 2024 regarding the same work being done without proper permits. The building has experienced various maintenance issues, including a roof leak repair in 2008, dry rot repair at the rear deck in 2020, and multiple stair-related improvements and safety violations in 2002 that were subsequently resolved, including repairs to the fire escape and various fire safety requirements.

Historical records show that major safety improvements were made in the early 1990s, including stair refurbishment, railing corrections, and the installation of hard-wired smoke detectors. The property has experienced several fire-related incidents, though none resulted in civilian injuries or significant damage. Most incidents involved cooking-related fires, smoke detector activations, or water leaks, with one unintentional building fire recorded.

The building's safety features have been monitored through various inspections, revealing an expired elevator certificate in 2009 and concerns about an old foundation in 2007. Recent activity around the property includes multiple 311 calls in late 2024 regarding sidewalk cleaning, parking violations, and graffiti, though these are typical urban maintenance issues rather than building-specific problems. The property's repair history suggests ongoing maintenance attention, with the most recent significant work being the kitchen and bathroom remodel filed in mid-2024, though this has led to permit compliance scrutiny.
