Initial analysis

The property at 857 30th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Central Richmond neighborhood, owned by the Mary Tong Trust and constructed in 1976. The building's recent history, dating back to 2021, has been marked by recurring issues with driveway access, with eight documented cases of blocked driveways requiring parking enforcement intervention between February 2021 and August 2024. All but one of these cases resulted in citations being issued to the offending vehicles, with vehicles ranging from SUVs to pickup trucks. The most recent incident occurred in August 2024, while there were three separate blocking incidents on October 1, 2023, including one that was deemed invalid due to incomplete reporting information.

In addition to parking-related issues, the property has experienced some general maintenance and cleanliness concerns. These include a service request in September 2022 that was completed by Recology, relating to an abandoned item, and a notable incident in July 2022 regarding waste receptacles (toters) being left out continuously, which prompted a city inspection. A property damage incident was reported in December 2021, though this case was transferred from 311 to emergency services. While the building's primary issues appear to stem from external parking challenges, the record shows these incidents have been consistently addressed through appropriate city channels and parking enforcement mechanisms.

Risk rating

How 857 30Th 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.
