Initial analysis

The four-unit multi-family residential building at 6528 California Street in Sea Cliff, owned by Jacques & Derderian, has undergone several significant renovations and faced some important safety compliance issues since its construction in 1922. The building has seen multiple remodeling projects in the mid-1980s, including kitchen and bathroom improvements in various units, along with the installation of skylights in units 3 and 4. More recent improvements include reroofing work in 1998, and two street space permits were issued in 2007 and 2018, though their specific purposes are not detailed in the records.

A notable cluster of building violations occurred in 2004, all of which were related to fire safety issues and subsequently resolved by July 21, 2004, including the need for fire sprinklers over garbage receptacles, proper fire extinguisher maintenance, and smoke detector installation in the lobby. Since then, there have been no recorded building violations. The property has experienced various maintenance and safety-related issues in the surrounding area, as evidenced by multiple 311 calls in recent years, including reports of sidewalk defects (2024), abandoned vehicles (2024), and tree damage (2021). The most recent building-related concern involves a sidewalk defect reported in July 2024, which remains open. While these external issues don't directly indicate problems with the building's condition, they provide context about the property's immediate environment and infrastructure maintenance.

Risk rating

How 6528 California 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.

Neighborhood percentile
50th percentile

Out of 20 buildings in this neighborhood, 10 are predicted to be safer.
