377-383 Guerrero St, San Francisco, CA 94103

The three-story multi-family residential building at 377-383 Guerrero St, owned by Chang Sing & Chin Bee Choo, was constructed in 1910 and contains three units. The property has undergone several significant changes over the years, most recently including a permitted change of use from a tattoo shop to a dog daycare in May 2024. This follows a lengthy history of commercial space conversions, including a retail to personal service change in 2006.

The building's maintenance record shows some concerning patterns, particularly regarding fire safety compliance. Between 2021 and 2024, there were multiple fire safety violations recorded, including issues with blocked exits, extinguishers, alarm systems, and multiple fire code violations in 2017 and 2024. While these violations were generally corrected promptly, their recurring nature suggests ongoing compliance challenges. The property has experienced several notable maintenance issues, including a serious plumbing situation in 2008 involving black sludge and extensive bathroom decay, though this was reportedly addressed promptly.

More recently, there have been complaints filed in 2024 regarding potential illegal commercial units and unauthorized changes of use, though these complaints are currently listed as not active. The building's recent history shows some ongoing exterior maintenance needs, as evidenced by multiple 311 calls in early 2025 regarding graffiti and debris, along with an open complaint about a damaged tree. While there have been historical fire incidents recorded, none resulted in civilian injuries, and the building has maintained its residential classification despite the commercial space conversions. The property's fire safety compliance history shows a pattern of violations being addressed, though the frequency of such violations raises concerns about ongoing maintenance practices.
