Initial analysis

The property at 743-745 9th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Inner Richmond neighborhood. Built in 1914 and currently owned by the Linda L Chang Trust, this flat/duplex structure has undergone several notable maintenance and safety incidents over its history. The most significant recent maintenance work was completed in 2007, when the building underwent a $16,000 reroofing project that has since been marked as complete. An earlier interior renovation was attempted in 1983 for unit #743, though this permit ultimately expired without documentation of completion.

The property has experienced recurring issues with street cleaning and general neighborhood upkeep over the past few years, with three separate reports of loose garbage documented in December 2020 alone. Between 2016 and 2020, there were multiple street-related incidents, including one hazardous materials case involving glass in October 2018, and various abandoned vehicle complaints that resulted in three tows and several vehicles leaving the area before enforcement arrival. The most recent reported building-related incidents have been primarily external and street-related, with no documented safety violations or hazardous conditions specific to the building structure itself. The historical record shows a pattern of neighborhood maintenance challenges, particularly regarding street cleaning and abandoned vehicles, though these appear to be more related to general neighborhood conditions rather than building-specific issues.

Risk rating

How 743-745 9Th 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.
