Initial analysis

The two-unit residential building at 1426 9th Avenue in San Francisco's Inner Sunset neighborhood was constructed in 1945 and is currently owned by Chan Wing Kit & Linda. The property has undergone several significant infrastructure improvements over the years, including a PG&E conversion from overhead to underground service with 200-amp capacity in 2004, furnace replacements in 2011, and more recently, a house trap replacement and sewer line repair in March 2020. Previous structural work included the replacement of garage door posts and beams in 2004, and subflooring and decking repairs in 1991, suggesting regular maintenance of the building's essential systems.

The property has experienced various maintenance issues and external incidents in recent years, with the most pressing concerns being tree root damage to the sidewalk (ongoing since August 2021) and a curb defect reported in September 2023. Other notable incidents include graffiti on the commercial portion of the building in December 2023, a sewage backup issue resolved in November 2021, and periodic parking enforcement matters. While these issues have generally been addressed through appropriate channels, with many cases marked as resolved, the building's recent history shows recurring concerns with tree root damage and infrastructure maintenance. The property appears to be maintained regularly, with major systems receiving necessary updates and repairs as documented through various permits and work orders.

Risk rating

How 1426 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
