Initial analysis

The two-unit residential building at 535 6th Avenue in San Francisco's Inner Richmond neighborhood is a two-story flats and duplex structure constructed in 1921, currently owned by James M. Lee and Bing Chiu Siu. The property has been subject to recurring sidewalk parking violations between 2020 and 2023, with three reported incidents - in February 2020 and June 2023 where officers were unable to locate the offending vehicle, and one in May 2022 that resulted in a citation. More recently, there was a street cleaning complaint regarding loose garbage and debris in July 2024, which has been resolved by the Public Works Street and Environmental Services department. The only other recorded incident was a pavement defect noted in September 2016, which was addressed and resolved by the Department of Public Works Bureau of Street Services and Repair. While the building itself appears to have no significant structural or safety concerns on record, the surrounding area has experienced recurring issues with illegal parking on sidewalks and occasional street maintenance matters.

Risk rating

How 535 6Th Ave'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.
