228 Diamond St, San Francisco, CA 94114

The 9-unit, 3-story multi-family residential building at 228 Diamond St, owned by the Thomas & Amy Mecham Family, has undergone several significant safety upgrades since its construction in 1964. Most recently, in October 2024, the building completed a fire alarm system upgrade to comply with current fire code requirements, including the installation of low frequency sounders in sleeping areas and upgrading the fire panel. The building has previously addressed critical safety concerns, including completing a mandatory soft-story retrofit in 2017 (Tier 4) and undergoing main service electrical upgrades in 2023.

Historical maintenance records show attention to basic infrastructure, with reroofing work completed in both 1999 and 2020, and termite repairs addressed in 1995. The building has experienced periodic building and fire code violations, though all noted violations have been addressed and abated. A cluster of fire safety violations was recorded in 2002-2003, concerning issues such as fire escape obstructions, alarm panel certification, and combustible storage, all of which were resolved.

More recently, a fire safety violation regarding exit maintenance was issued in July 2023, which was abated by November 2023. The property has maintained regular communication with city services for general maintenance issues, as evidenced by multiple 311 calls between 2010 and 2024, primarily related to street cleaning, graffiti removal, and tree maintenance. While there was one notable complaint in 1994 regarding elevator service affecting a disabled resident, this was resolved by 1995, and no similar accessibility issues have been reported since.
