Initial analysis

The two-unit multi-family residential building at 6042 California Street, owned by Susan Ng Pon, was constructed in 1924 and has experienced several significant events throughout its history. Most notably, in April 2001, the property faced multiple violations related to lead paint hazards, floor covering repairs, and a water heater issue, though these were all resolved by July 10, 2001. A concerning unpermitted unit complaint was filed in February 2022 but was quickly resolved by March 4, 2022. The building underwent some infrastructure maintenance in 2011 with a street space and sidewalk repair project, as well as the replacement of a house trap, both of which were completed.

Recent years have seen the property primarily involved in external matters rather than internal building issues. There were two informal fire complaints in 2006 and 2012, with the 2006 complaint requiring correction of conditions before closure in 2015. The surrounding area has generated numerous 311 calls from 2023 to 2025, primarily concerning parking violations and street cleaning issues, including multiple reports of driveway blocking, garbage, and debris. While these external matters don't directly impact the building's habitability, they provide insight into the general neighborhood conditions. A tree maintenance issue was reported in April 2024 and remains open as of the latest data, though this is also an external matter not directly affecting the building's condition.

Risk rating

How 6042 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
28th percentile

Out of 660 buildings in this neighborhood, 475 are predicted to be safer.
