646-650 Laguna St, San Francisco, CA 94102

The three-unit residential building at 646-650 Laguna Street in Hayes Valley, owned by Robert Colin Macphee, is a three-story structure built in 1900. The building's maintenance record shows a significant re-roofing project completed in 2018 at a cost of $27,250, while earlier records indicate foundation repairs and ADA compliance work were attempted in 1999, though those permits eventually expired.

The property has experienced multiple fire-related incidents over the years, including a building fire and outside rubbish fire, both of which were intentionally set but fortunately resulted in no civilian injuries. Other concerning incidents include two cooking-related fires (both contained), a gasoline spill, and several motor vehicle accidents near the property, though most of these incidents occurred at least a decade ago. Recent activity around the building from early 2025 has primarily consisted of street maintenance issues, including multiple reports of garbage and debris, illegal postings, and a graffiti incident involving a bike rack.

Some of these issues, such as exposed pole wires and street lighting concerns, have been determined to be outside the jurisdiction of city services. The building's utility infrastructure is currently being upgraded through an approved installation of T-Mobile wireless equipment on an existing utility pole. While the property has experienced various maintenance and incident issues over the years, the most recent records show ongoing environmental and street maintenance challenges rather than any immediate building-specific problems.
