Initial analysis

Located in San Francisco's Central Sunset neighborhood, this two-unit residential building at 1210-1212 21st Avenue is a two-story flats and duplex structure built in 1926, currently owned by the Arlene Won Jeung Survivors Trust. The building has undergone several significant maintenance updates over the past few years, with the most recent being a completed re-roofing project in September 2022 costing $12,900, along with the installation of new hardie board siding on the back of the building in September 2022. Historical records show earlier maintenance work including garage expansion and interior plaster repairs in 2001, and a previous roofing project completed in 1996.

The property has experienced recurring issues with driveway access in 2023, with nine documented cases of blocked driveways between January and July 2023. Of these, seven cases resulted in citations being issued, while three others were dismissed due to incomplete reporting. The building's street-facing maintenance record appears solid, with no recorded violations or major incidents affecting resident safety or comfort. The most recent building improvements, particularly the new roofing and siding, suggest ongoing maintenance attention from the current ownership.

Risk rating

How 1210-1212 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

Out of 814 buildings in this neighborhood, 65 are predicted to be safer.
