The building contains 66 units and has experienced several significant maintenance and safety issues over recent years.

Several building violations have been recorded, particularly in 2022-2023, related to water damage, lighting, and boiler permits.

The property has undergone multiple roofing projects throughout the years, with completed permit work in 2013-2014 totaling significant costs.

Historical records show routine kitchen electrical wiring work in 2007, and the building experienced multiple interior maintenance violations in 2004, including water damage and wall repair issues.

Risk rating

How 3-31 Diaz 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
