Initial analysis

The three-unit multi-family residential building at 522-524 Natoma Street in San Francisco's South of Market neighborhood was constructed in 1909 and has undergone several significant maintenance and repair work over the years, with the most notable issues occurring recently in 2019. During mid-2019, the property experienced multiple housing code violations including inadequate heating in occupied rooms, window latch problems, general dilapidation concerns, and issues with garbage receptacle placement. These violations were formally documented between June 13-24, 2019, and were all abated by July 11, 2019. The building has a history of maintenance challenges, including water damage repairs in 2013, stairway dry rot issues in 2004, and a fire-related siding replacement in 2005. More recent infrastructure updates include a water heater replacement in 2015 and various other repairs totaling over $30,000 in the early 2000s for window and siding work.

The property has undergone several routine housing inspections since 2004, and while most violations have been promptly addressed, the frequency of maintenance issues suggests ongoing upkeep is required. Recent 311 calls from late 2024 through early 2025 show consistent reports of garbage and debris on the street, though these external issues relate more to the surrounding area than the building itself. The only recorded fire incident was a malfunctioning smoke detector, with no injuries reported. The building's current owner, Gregory L Blatman Tr, has maintained the property through various permits and repairs, though the concentration of housing violations in 2019 indicates there was a period requiring significant attention to building systems and maintenance standards.

Risk rating

How 522-524 Natoma 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.
