Initial analysis

The property at 523 33rd Avenue is a three-story, two-unit multi-family residential building located in San Francisco's Outer Richmond neighborhood, owned by the Chan/Szeto Family Trust. The building, constructed in 2001, followed a series of developments and demolitions starting in 1998, when a single-family dwelling was cancelled for demolition. Two permits from 2000, one for the main construction and another for minor foundation revisions, respectively, accounted for approximately $3,000 in work. Through its history, the building has experienced recurring issues with parking violations, particularly driveway blockages, with nine documented cases between 2020 and 2025, most recently in January 2025, including three citations issued in 2022 and one for sidewalk parking in 2021. Other recent incidents include graffiti on public structures in October 2024, resolved by street services, and an electronics debris removal in June 2024. The building's only recorded fire incident was a false alarm activation with no fire or injuries. Of particular note is the building's relatively high frequency of parking-related complaints, suggesting ongoing challenges with street access and parking management in the immediate area.

Risk rating

How 523 33Rd 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.

Neighborhood percentile
