This three-story multi-family residential building, constructed in 1903, contains two units and is owned by Wong Kwok-ho & Ng Mai Sim. The property has experienced several maintenance and compliance issues over the past two decades, with the most recent activity being a stair repair completed in September 2023. The building has a history of significant stair-related concerns, including a December 2017 complaint about disrepair that was eventually addressed by November 2018. There were also multiple violations related to lead paint hazards, window glazing, and an unauthorized rear structure constructed in 2003. In 2007, the property underwent reroofing work, but there were complaints about unauthorized roof demolition and debris management during this period. More recently, in September 2023, there was a complaint about unpermitted front staircase replacement work, though this was followed by the proper repair permit obtained in September 2023. The building's exterior areas have experienced recurring issues with parking enforcement, with numerous reports of driveway blocking between 2024 and 2025, and there is currently an open issue regarding a collapsed sidewalk reported in August 2024. A tenant buyout occurred in 2015 for $45,000 at a neighboring address (152 4th Avenue), but there are no records of similar actions at this property directly.

How 144-146 4Th 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.
Out of 660 buildings in this neighborhood, 396 are predicted to be safer.
