The two-family residential building at 4131 Balboa Street in San Francisco's Outer Richmond neighborhood is a two-story flats & duplex structure built in 1947, currently owned by Michael M. Shiro. The property has undergone several significant modifications in recent years, with the most substantial work occurring between 2023 and 2024.

How 4131-4133 Balboa 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
