Initial analysis

The two-unit residential building at 351 3rd Ave in San Francisco's Inner Richmond neighborhood, owned by the Lily Moy Trust, is a two-story flats and duplex structure built in 1902. The property has undergone several modifications over the years, including a significant bedroom and bathroom addition project initiated in 1983 (though the permit ultimately expired), and more recently, in 2008, the replacement of two entry doors into existing openings, which was properly permitted. A concerning issue arose in August 2015 when a complaint was filed regarding an allegedly unauthorized garage unit installation, though this matter appears not to have progressed to active investigation.

The building has experienced various maintenance and resident-related issues in recent years, particularly between 2021 and 2024. Notable incidents include sewer-related problems (with a backup event in June 2023), periodic issues with garbage and debris on the property, and several instances of vehicles blocking driveways. The property has also faced infrastructure concerns, with an open sidewalk pavement defect reported in October 2024. While many of these issues have been resolved through appropriate channels, there are several ongoing matters of note, including an open encampment report from November 2022 and a recent sidewalk pavement defect that remains in open status as of October 2024. The building has maintained proper permitting for most of its recent modifications, with only the 2015 complaint regarding an unauthorized unit standing out as a potentially significant compliance issue, though its lack of active status suggests it may not have been substantiated.

Risk rating

How 351 3Rd 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 1723 buildings in this neighborhood, 706 are predicted to be safer.
