221-223 Diamond St, San Francisco, CA 94114

The property at 221-223 Diamond Street is a two-story, two-unit multi-family residential building located in the Eureka Valley/Dolores Heights neighborhood, constructed in 1927 and currently owned by Cyril A. Hackett.

The building's documented history shows several maintenance and improvement efforts over the past few decades, including completed projects for kitchen and bathroom remodeling in 1999, reroofing in 1990, and attempts to construct storage spaces in 1998 (application expired). Two sidewalk-related permits were filed in 2001, though these permits also expired without completion. The most significant recent activity around the property has been a series of municipal service calls in 2024, primarily related to street and sidewalk cleanliness issues, with ten cases recorded between July and December 2024.

These incidents primarily involved reports of garbage and debris, including furniture and loose waste, all of which were addressed and resolved by city services. There were also two encampment-related calls (in July and January 2025) near the property, with the most recent case being closed due to individuals being "unable to locate." Other recent issues include a damaged bike rack (November 2024) and a defaced MTA sign (August 2024), though these were not directly related to the property itself. While the building's structural improvements have been relatively minimal in recent years, the primary concerns appear to be external conditions related to street cleaning and maintenance rather than any direct building-specific issues.
