Initial analysis

The two-unit residential building at 4206-4208 Anza Street in San Francisco's Outer Richmond neighborhood has undergone several significant maintenance and improvement works since its construction in 1974. The property, currently owned by Kyoko Nonaka, received multiple roofing interventions, most recently in 2009 with a $9,000 project, and previously in 1993 (though that permit expired). The building received substantial exterior maintenance in 2003, including stucco replacement on the front facade and the installation of 12 new windows. More recent mechanical upgrades include the replacement of both furnaces in early 2014, with one installation recorded as complete and another permit showing as expired.

The property has experienced various issues in the surrounding area, as documented through 311 calls, with the most recent incidents occurring in 2023-2024 involving garbage and debris, including a report of human waste. Other notable external incidents include a parking enforcement call in December 2023 and recurring issues with hazardous materials (specifically glass) on the street documented in November 2016. The building's maintenance history shows regular attention to structural and mechanical systems, with no documented major internal building code violations or safety concerns. A building inspection request in July 2020 resulted in no action required, suggesting no immediate building concerns were identified at that time.

Risk rating

How 4206-4208 Anza 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.
