39 Diamond St, San Francisco, CA 94114

39 Diamond Street is a 3-unit residential building constructed in 2008 in the Eureka Valley/Dolores Heights neighborhood. The three-story flats/duplex structure was built following the demolition of a single-family dwelling in an RH-3 district, with comprehensive safety systems including a complete fire sprinkler system and a fire alarm system installed during construction, with revisions made to central monitoring and pull station configurations.

The building underwent several infrastructure enhancements, including a $30,000 deck construction project in 2018, and has maintained up-to-date safety systems with a 400-amp service installation and four meters for individual units. The property has faced some recent neighborhood challenges, with multiple reports of graffiti on public infrastructure in early 2025 and several instances of street cleaning issues documented throughout late 2024, including cases of garbage, debris, and one instance involving a mattress.

However, all these issues have been promptly addressed and resolved by city services. The building's construction history is well-documented, with proper permits obtained for all major systems including plumbing (bathrooms, kitchens, water heaters, laundry), gas furnace installation, and electrical systems, establishing a comprehensive record of responsible development practices. The property has undergone no major modifications or safety incidents since its construction, suggesting stable ongoing maintenance of the building systems.
