300 Green St, San Francisco, CA 94133

The 8-unit, 3-story multi-family residential building at 300 Green St in Telegraph Hill, owned by the Velma Guglielmone Trust 200, was constructed in 1923 and has undergone several significant maintenance and safety upgrades over its lifetime. Most notably, the building completed mandatory seismic soft-story retrofit work in 2015, which included the installation of steel moment frames and plywood shearwalls at a cost of $65,000.

The property has a documented history of stairway maintenance issues, with multiple repairs to both front and rear stairs documented between 1991 and 2007, indicating ongoing structural care of common areas. The building experienced significant safety compliance issues in 2019, when unauthorized renovations in Unit #1 led to multiple building, electrical, and plumbing violations, including the reportedly illegal removal of load-bearing walls and unauthorized kitchen modifications. These violations, filed between February and April 2019, were ultimately addressed through proper permitting and corrections completed in late 2019, involving kitchen and bathroom remodels and electrical/plumbing corrections costing $6,000.

While there have been several building code compliance issues over the years, including a 2012 complaint about cracked stucco, most recent building inspections have shown no active violations. The property achieved its seismic compliance requirements as a Tier 3 soft-story building with work completed and Certificate of Final Completion issued. Recent maintenance activities have focused on exterior issues, with multiple 311 calls in 2024/2025 regarding street cleaning, tree maintenance, and sidewalk conditions near the property, although these are primarily municipal infrastructure concerns rather than building-specific issues.
