Initial analysis

The property at 3871-3873 California Street is a three-story, two-unit multi-family residential building located in the Jordan Park/Laurel Heights neighborhood, owned by the Leong Family Trust since 1992 and constructed in 1920. The building has undergone several significant renovations and repairs over the past decade, including substantial interior remodeling in 2012 that involved combining rooms, adding bathrooms, and installing new water heaters throughout the building. More recent improvements in 2020 included window replacements and wood repairs at the rear of the building. However, there are serious ongoing concerns regarding lead paint safety that emerged in October 2019, with multiple violations issued for damaged paint creating potential lead hazards, improper weatherproofing, and building work conducted without proper permits. These lead-related violations, which pose health risks particularly to vulnerable populations, remain active as of the latest available information.

The building's maintenance history shows attention to essential systems, including a complete electrical upgrade in 2011 with new panels and circuits installed throughout the building. Recent maintenance issues have primarily involved exterior concerns, with multiple 311 reports in 2023-2024 related to graffiti on sidewalks, though these are not major structural or safety concerns. The property has also experienced some routine urban maintenance issues typical of its location, such as driveway blocking and refuse handling complaints in 2024. While the building has received various upgrades to its infrastructure and living spaces over the years, the persistent issues related to lead paint and the history of unpermitted renovation work suggest ongoing challenges with property maintenance and safety compliance.

Risk rating

How 3871-3873 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.
