Initial analysis

The five-unit multi-family residential building at 1556 9th Avenue in the Inner Sunset, owned by Lau Garson, was constructed in 1951 as a single-story apartment building. The most recent significant renovation was completed in 2021-2022, involving a comprehensive remodel of a basement unit's kitchen and bathroom, including electrical and plumbing updates costing approximately $25,000. Historically, the building has undergone several kitchen renovation projects in the 1990s, including cabinet and counter replacements in 1992, 1999, and 1999.

The building has a documented history of fire safety-related violations from 2008, including issues with fire extinguisher maintenance, combustible storage, and yard cleanliness, all of which were abated by February 2009. Two notable complaints were filed regarding construction activities: a roof removal operation in 2020 that generated dust near pedestrian traffic, and unpermitted construction in 2010. The property has experienced periodic maintenance and safety inspections, with records showing routine inspections in 2001, 2008, and 2010. Recent 311 calls from 2023-2024 have primarily related to external issues such as garbage, sidewalk parking, and tree maintenance, rather than building-specific concerns. The only recorded fire incident was an emergency medical service call with no civilian injuries reported.

Risk rating

How 1556 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.

Neighborhood percentile

Out of 1493 buildings in this neighborhood, 1269 are predicted to be safer.
