Initial analysis

The two-unit residential building at 590 42nd Avenue in San Francisco's Outer Richmond neighborhood is a two-story flats and duplex structure built in 1945, currently owned by the Kono Family Trust. The most significant recent maintenance work recorded was a complete reroofing project in December 2022, costing $14,000. The property has experienced recurring issues with parking violations in its vicinity over recent years, with multiple documented incidents between 2018 and 2023. Most notably, there were four documented cases of driveway blocking (May 2023, July 2020, November 2018, and June 2018), with only one resulting in a citation. Additionally, there were two reports of sidewalk parking (April 2023 and March 2022) and an incident involving construction equipment blocking a parking space in October 2022, though conditions were not found at the time of inspection. The property has also faced some street cleaning challenges, with reports of loose garbage requiring attention in June and July 2022. While these parking and street maintenance issues are worth noting, it's important to emphasize that many reported violations could not be validated by responding officers, suggesting that not all complaints corresponded to verifiable conditions.

Risk rating

How 590 42Nd 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.
