Initial analysis

The two-unit residential property at 1531 12th Avenue in the Inner Sunset District is a two-story flats and duplex building constructed in 1946, currently owned by the Hui Family Trust. The building's maintenance history shows a few significant improvements, including a vinyl siding installation completed in 1990 and a reroofing project initiated in 1997, though the roof permit has since expired. Another historical permit from 1981 is on record, but its specific details are not provided in the available data.

The property has experienced several transportation-related incidents in recent years, though none directly related to the building's condition or safety. These incidents include a driveway blocking incident in August 2022, a double parking complaint involving a Toyota Camry in February 2020, and a streetlight outage on a wooden pole near the property that was resolved by PG&E in December 2016. While these issues impacted the immediate vicinity of the building, they primarily relate to street and parking conditions rather than the property's structural or residential systems. The relatively minimal number of permits and service calls on record could suggest either limited maintenance needs or potentially incomplete documentation of historical work performed on the property.

Risk rating

How 1531 12Th 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
