Initial analysis

The three-unit residential building at 4707-4711 California Street in San Francisco's Inner Richmond neighborhood is a three-story structure built in 1910, currently owned by the Mo & Chu Lam 2017 Family Trust. The building has undergone several significant maintenance and safety upgrades over the years, including a complete reroofing project in 2022 costing $27,200, and front stucco replacement work in 1991. The property has faced multiple safety and code compliance issues, with the most recent major set of violations recorded in 2017 during an annual routine inspection, where several important safety concerns were identified, including the need for carbon monoxide detectors, proper hot water heater flue pipe installation, fire extinguishers, and updated building safety documentation. Earlier violations from 2000 involved combustible storage issues and gas utility shutoff tool requirements, all of which were subsequently abated.

Recent activity at the property has included a sewage backup incident in June 2024 and multiple parking enforcement issues, including several citations for sidewalk parking violations. There have also been reports of offensive graffiti in July 2023 and loose garbage concerns in December 2023. The building's history includes a notable complaint in 2003 regarding bathroom issues, mold, and lead concerns, and a 2014 fire alarm system inspection which was resolved with conditions corrected. The property has maintained compliance with building codes since a 1983 remediation project to bring it up to code, and while some violations have recurred over the years, records indicate prompt attention to abatement once violations are identified.

Risk rating

How 4707-4711 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
