Initial analysis

The Seiki Family Trust owns this two-unit, two-story multi-family residential building located at 768-770 21st Avenue in San Francisco's Central Richmond neighborhood. Built in 1921, the flats/duplex structure has had limited documented construction activity, with only two permits on record: a street space permit issued in 2015 and an expired re-roofing permit from 1990.

The property has experienced several parking-related incidents in recent years, with multiple complaints about sidewalk parking between 2019 and 2022, though only one of these (January 2020) resulted in a citation. A driveway blocking incident in September 2019 also resulted in a citation. A noteworthy safety concern was addressed in September 2020 when a collapsed sidewalk and damaged curb were reported, though these issues were documented as being scheduled for repair within two weeks. More recently, in October 2023, there was a scooter-related service request that resulted in a warning being issued. While the building's permit and complaint history shows some parking enforcement activity and one significant sidewalk defect, there are no documented major structural or safety concerns in recent years.

Risk rating

How 768-770 21St 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
