Initial analysis

The two-unit residential building at 585-587 Potrero Ave, located in San Francisco's Potrero Hill neighborhood, was constructed in 1927 and includes both flat and commercial spaces. The property, owned by Juan J. Sanmames and Rosa M. Sanmames, has undergone several improvements over the years, including aluminum window installation in 1983 and two separate solar power system installations in 2018, though both solar permits are now expired. More concerning are recent issues with the property, particularly regarding the commercial storefront that has faced multiple complaints between 2020 and 2024 about being unregistered and abandoned, with the most recent violation filed in November 2024 carrying administrative hearing fees. The building has experienced two fire-related violations in 2023 and 2024, including multiple fire code violations and two associated administrative hearing fees, though there were no civilian injuries reported in any fire incidents. Infrastructure maintenance records show reroofing work from 1999 and a fire system installation in 1997, both now expired.

The property has a documented history of maintenance and compliance issues, including a notable plumbing incident in 2010 involving possible sewage problems that were resolved within six months. Recent years have seen persistent issues with graffiti and exterior maintenance, with multiple 311 calls in 2023-2024 regarding graffiti removal, public works requests, and garbage concerns. These external maintenance issues, while not immediately impacting resident safety, indicate ongoing challenges with property upkeep and neighborhood maintenance. The building's systems and infrastructure improvements, such as the solar installations and previous fire safety upgrades, suggest investment in modernization despite the property's recent compliance difficulties with both fire safety and commercial vacancy regulations.

Risk rating

How 585-587 Potrero 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

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.
