1654-1658 Union St, San Francisco, CA 94123

The three-story, 6-unit multi-family residential building at 1654-1658 Union St in Cow Hollow, owned by Robert P. Groppi, has undergone significant safety and modernization improvements since 2018, most notably completing a mandatory soft-story retrofit in compliance with San Francisco building codes.

Recent safety enhancements include the installation of a comprehensive fire alarm system with low-frequency sounders in key living areas and off-site communication monitoring, completed in 2021 at a cost of $21,850, along with a full bathroom and kitchen remodel of one unit that same year. The building has seen substantial electrical upgrades, including new sub-panels and circuits, as well as HVAC improvements with new furnace installation and ventilation systems. The property has maintained regular housing inspections, with records showing routine inspections in 2000 and 2007, and no active violations noted in recent years.

Infrastructure improvements date back to the 1990s when aluminum windows were installed and the roof was replaced. Recent 311 calls primarily relate to street conditions and parking enforcement, with no documented building code violations or habitability concerns. The soft-story retrofit project, classified under Tier 4, has been completed with a Certificate of Final Completion issued, demonstrating compliance with seismic safety requirements.
