Initial analysis

The 2-unit, 1-story multi-family residential building at 1538 Thomas Avenue in the Bayview neighborhood, owned by James Ming Zhu, has a documented history of maintenance and safety issues, particularly in 2018 when multiple violations were recorded related to door repairs and egress obstructions, which were resolved within approximately one month of being cited. More recently, between December 2024 and January 2025, the property experienced several concerning plumbing issues, with multiple reports of sewage back-up discharges through side vents and other locations, though these cases were subsequently resolved. The building has also faced challenges with waste management, as evidenced by multiple reports of garbage and debris incidents in late 2024, including furniture abandonment on the street that required city intervention.

The property has a documented fire safety history, with a notable incident in 2017 involving blocked exits, which was promptly corrected within a few weeks. While there is a record of two tenant buyouts in the vicinity of Thomas Avenue and Shafter Avenue, the only significant payment was for $27,900 to two tenants at 1555 Shafter Avenue in May 2022. The building's exterior infrastructure has also been subject to scrutiny, with reports of curb defects in November 2024, though city services' responses indicate some issues were duplicative in nature. While most recent complaints have been addressed and marked as closed, the pattern of sewage and waste management issues in late 2024 and early 2025 stands out as the most pressing recent concern.

Risk rating

How 1538 Thomas 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
62th percentile

Out of 382 buildings in this neighborhood, 145 are predicted to be safer.
