Initial analysis

The two-story multi-family residential building at 3200 26th Street in San Francisco's Inner Mission neighborhood, owned by David M Helbraun 2009 Revoc, was built in 1906 and contains 4 units plus a commercial space. The property has a documented history of maintenance and safety issues, with the most significant problems occurring between 2008-2010, when there were multiple complaints about black mold, inadequate heating, security concerns, and various maintenance deficiencies. These issues led to several building violations in October 2000, including problems with interior surfaces, stairs, drainage pipes, and heating systems, all of which were eventually abated by November 22, 2000. The building underwent various repairs and upgrades between 1998 and 2012, including termite damage repairs, water heater relocations, electrical system upgrades, and compliance with various violation notices, most notably a comprehensive package of work in 2010 that addressed sheetrock patching, glass replacement, lock updates, and egress path verification.

Recent building history shows primarily routine maintenance and service issues, with no major complaints or violations recorded since 2010. Fire department records indicate some sprinkler activations and alarm transmissions, but no serious incidents or civilian injuries have been reported. The property has experienced ongoing issues with sidewalk cleanliness, as evidenced by multiple 311 calls in late 2024 regarding garbage and debris, though these external maintenance issues are separate from the building's internal condition history. While the extensive maintenance history from the 2000s raises some concern about past living conditions, it's important to note that the property appears to have been maintained and upgraded to address most of these historical issues, with all documented violations having been officially resolved.

Risk rating

How 3200 26Th 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.
