Initial analysis

The 6-unit, 3-story multi-family residential building at 33-35 San Carlos Street in the Inner Mission, owned by the Hsu Family Trust, has undergone several significant improvements since its construction in 1910. Most notably, the building completed its mandatory soft-story retrofit in 2015 at a cost of $50,000, achieving compliance with seismic safety requirements. Recent maintenance includes two reroofing projects, with the most recent in 2022 costing $12,000, showing ongoing commitment to building upkeep. The building has undergone multiple structural improvements, including significant stair and deck repairs in 2001 ($30,000) and earlier bathroom work in 1986.

The property experienced several safety-related compliance issues in early 2023, when multiple violations were recorded including problems with fire extinguisher maintenance, fire escape equipment, and gas utility shutoff tools. However, all these violations were promptly abated within one month of being issued. Additionally, there is an active complaint from 2022 regarding a potentially illegal basement unit that remains unresolved as of 2023. The building has a history of routine safety inspections dating back to 1998-2011, indicating regular oversight of building conditions. Recent months (2024-2025) have seen multiple reports of sidewalk debris and abandoned furniture, though these are external to the building itself and have all been resolved through city services.

Risk rating

How 33-35 San Carlos 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.
