Initial analysis

The two-unit residential building at 585-587 San Bruno Avenue in Potrero Hill is a two-story flats and duplex structure, built in 1941 and currently owned by the Biradelli Family Trust. The property has undergone several significant improvements over the past two decades, with the most recent major work being a $31,800 reroofing project initiated in December 2021. Prior substantial renovations include a 2007-2009 comprehensive remodel of both flats featuring kitchen renovations, new wall openings between dining and living rooms, and a horizontal addition at the rear including garage modifications, valued at approximately $211,000 combined. Additional improvements from 2006 included the installation of 24 vinyl replacement windows.

The building's maintenance history shows attention to infrastructure, including a 2020 main sewer line replacement, though this permit ultimately expired. The property has experienced four documented sewage backup incidents between August and November 2020, all involving catch basin issues that required PUC Sewer Operations intervention and were subsequently resolved. While these incidents occurred over three years ago, it's noteworthy that the main sewer line replacement permit was never finalized. Recent external maintenance requests have been limited to issues affecting the surrounding area rather than the building itself, including reports of pavement defects, sidewalk cleaning needs, and graffiti (most recently in August 2023). The building's systems have been upgraded to modern standards, as evidenced by the 2006 window replacement and comprehensive electrical system updates performed during the 2007 renovation, which included the installation of numerous new fixtures, switches, receptacles, and circuits throughout the property.

Risk rating

How 585-587 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.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
