Unlock complete reportThe 6-unit, 2-story apartment building at 4320 Judah Street in the Outer Sunset, owned by the Lin Family Trust, has a documented history dating back to 1992 and shows both maintenance efforts and ongoing concerns with building systems. Most recently, in 2024, the property underwent an electrical upgrade with the installation of 7 new 200-amp electrical meters. However, significant recent fire safety issues have emerged, with violations referred to hearing in June 2023 regarding exits/obstructions and alarm system maintenance. There have been multiple fire safety complaints between 2019 and 2023, including issues with alarm systems, exit maintenance, and blocked exits, though most prior violations were corrected promptly. A concerning pattern of maintenance issues is evident, including a 2023 complaint about recycling bin placement and debris, and historical problems with windows (2006), dry rot/termite damage (2000), and various repairs in the 1990s. The building has undergone several significant improvements over the years, including window replacement (2007-2008), fiber cement siding installation (2016), and reroofing (1999). Recent 311 calls from 2023-2024 indicate various external maintenance needs and neighborhood conditions near the building, though these are not direct building maintenance issues. A 2023 complaint regarding potential business operations in unit 5 producing chemical smells was closed as cancelled. While the building has experienced recurring issues with fire safety systems and general maintenance, most violations have been addressed through either correction or proper notification procedures, with the notable exception of the recent violations from June 2023 that are still pending hearing resolution.

How 4320 Judah St'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.
Out of 632 buildings in this neighborhood, 436 are predicted to be safer.
