Initial analysis

The two-story, four-unit multi-family residential building at 4500-4504 Cabrillo Street in San Francisco's Outer Richmond neighborhood, owned by Szeto Lock Him, has experienced several significant maintenance and safety issues since its construction in 1924. The most substantial historical concerns emerged in late 2004 when multiple violations were documented, including issues with stairs, exterior door security, and fire safety requirements such as sprinkler installation over garbage receptacles. These violations, filed on November 4, 2004, were all addressed and abated by March 17, 2005, through a permit that included stair repairs and sprinkler installation.

More recently, the property has faced recurring issues with its commercial storefront, being cited for vacant storefront violations in 2018, 2019, and 2022, though these violations are no longer active. The building has experienced significant plumbing issues in the past year, with multiple reports of sewage backup discharges from the side sewer vent in both August and July 2024, as well as sewer odor problems in September 2024. Other maintenance concerns have included occasional reports of garbage and debris (most recently in August 2024) and parking-related complaints. While these maintenance issues indicate ongoing challenges, it's worth noting that the building has not had any reported fire incidents related to civilian injuries. The most recent building-related activity includes several 311 calls in 2024 regarding various city services, including sewer operations, street cleaning, and parking enforcement, though these are primarily related to external conditions rather than the building's structural integrity or safety systems.

Risk rating

How 4500-4504 Cabrillo St'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.
