236-238 Diamond St, San Francisco, CA 94114

The two-unit residential property at 236-238 Diamond Street, located in the Eureka Valley/Dolores Heights neighborhood, is a 2-story flats/duplex building constructed in 1909 and currently owned by the Ortega-Chang Living Trust. The building has undergone significant recent renovations, with the most substantial work occurring between late 2022 and 2024, including foundation leveling ($49,700), structural updates, and footprint expansion of the rear portion ($250,000). Multiple revisions have been made to these permits, including additional windows and structural modifications.

The property has seen substantial infrastructure improvements, including a complete electrical upgrade to replace old knob and tube wiring, installation of new smoke detectors, and comprehensive plumbing work involving kitchen remodels, new tankless water heaters, and sewer repairs. A notable tenant buyout occurred in 2015 for $29,500 involving two tenants at 238 Diamond Street. The building's maintenance history suggests proactive upkeep, with recent work addressing both comfort and safety systems, including furnace replacement, plumbing updates, and electrical system modernization.

While there have been some building issues, such as a sewage backup in 2021 and various infrastructure upgrades, these appear to be part of regular maintenance rather than emergency repairs. The property has complied with recent building codes, as evidenced by the multiple permits obtained and completed work. External incidents recorded through 311 calls have primarily involved minor issues like parking violations and street cleaning matters, rather than building-specific problems.
