AI summary

The two-unit residential building at 620 San Bruno Avenue in Potrero Hill is a two-story flats and duplex structure constructed in 1890, currently owned by Bui-chu Revoc Tr. The property has undergone several significant improvements in recent years, with the most substantial being electrical system upgrades in 2024 including a new 200-amp service installation and replacement of six front windows in the same year. Previous major works include a gas water heater replacement in 2022, complete gas line replacement in 2018, and reroofing in 2014. An address modification was recently processed in August 2024, changing the address from 260-1/2 San Bruno Avenue to 260A.

The building's history shows one electrical complaint in 2010 regarding unauthorized panel changes, though this was quickly addressed. The property has experienced periodic street maintenance issues near the building, with multiple reports of loose garbage (2016-2020) and two tree-related incidents (damaged tree in 2017 and hanging limb in 2024). A notable tenant buyout occurred in June 2017, involving four tenants and totaling $28,000. Historical planning records indicate the property underwent a lot subdivision process, creating two separate lots for the two-unit dwelling, which was completed with CEQA clearance. While the building's maintenance and improvement record shows regular upkeep, the presence of multiple street cleaning and maintenance calls suggests ongoing challenges with the immediate surroundings.

Risk rating

How 620 San Bruno Ave's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.
