517-523 Greenwich St, San Francisco, CA 94133

The 6-unit, 3-story multi-family residential building at 517-523 Greenwich Street in Telegraph Hill, built in 1912 and currently owned by Borangno Family Survivors Trust, has undergone significant safety and infrastructure improvements in recent years. Most notably, the building completed its mandatory soft-story retrofit in 2017 (as a Tier 3 building) to improve seismic safety, and in 2019, substantial HVAC upgrades were implemented including replacement of ductwork, installation of new heat pump fan coils, and a furnace replacement with associated electrical circuitry work totaling over $70,000 in improvements.

The building received important safety upgrades including a new local fire alarm system with low-frequency horns and smoke detection in 2019, and a comprehensive electrical system upgrade in 2010 that modernized wiring and lighting throughout multiple units. The property has a history of maintenance issues documented in 2004, with several housing code violations including problems with lighting, electrical systems, and interior surfaces. These issues, which included concerns about lead paint, were all addressed and abated by September 2005.

Since then, the building has received regular maintenance and upgrades, with the most recent work focusing on HVAC, electrical systems, and fire safety. Recent utility-related incidents include a water valve leak in September 2024 and various parking enforcement issues, though these do not significantly impact the building's condition. The property has maintained active compliance with safety regulations, as evidenced by the completed soft-story retrofit and various infrastructure improvements, though residents should note there are ongoing open cases regarding noise (October 2024) and recent environmental health requests (September 2024).
