Initial analysis

The 2-unit residential building at 1809-1811 9th Avenue in San Francisco's Inner Sunset district is a two-story structure built in 1965, currently owned by the Hwang Family Trust. The building's permit history shows an electrical upgrade attempt in 2004, when a 200-amp underground conversion project was initiated, though this permit has since expired. Recent incidents related to the property have predominantly involved parking violations, with three documented cases of sidewalk parking in 2020, one of which resulted in a citation in July 2023. Other maintenance issues in the vicinity have included a graffiti incident in April 2020 that was promptly addressed and repaired, and a streetlight replacement in August 2011 due to flickering.

The building's safety record shows no significant fire incidents or civilian injuries, though there was one documented case of an alarm system malfunction. The property's maintenance history includes a response to a litter receptacle issue in January 2021 and a tree maintenance inspection in October 2020, neither of which indicated any serious concerns. While the property has experienced multiple parking-related issues in the surrounding area, these appear to be more reflective of neighborhood conditions rather than building-specific problems, and have generally been addressed by appropriate city departments. The most recent recorded incident was a parking enforcement call in September 2024, which resulted in an officer being unable to locate the reported vehicle.

Risk rating

How 1809-1811 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.
