Initial analysis

The property at 26-32 Isis Street in San Francisco's South of Market neighborhood is a two-story, four-unit multi-family residential building constructed in 1913 and currently owned by the Cowan Robert Estate Of. The building has undergone several maintenance and improvement projects over the years, including multiple window replacements in 1999 (with six and seven windows replaced in separate projects), plumbing upgrades in 2011 (valve replacement and acrylic surround installation), and electrical work in 2010 to install a house meter and new grounding in the garage. In January 2011, the building experienced several health and safety violations that were documented and subsequently resolved by February 2011, including issues with water heaters, fire extinguisher maintenance, and handrail repairs.

The most recent significant complaint occurred in August 2023, when a resident reported concerns about toxic air coming from upstairs units through the vents, though this complaint is now listed as not active. Since then, the building has undergone routine safety inspections in 2007 and 2011. Recent activity at the property has primarily involved parking-related issues, with multiple complaints about driveway blocking between November 2024 and December 2024, though enforcement could not be carried out in most cases. There was also one instance of a noise complaint in November 2024 that remains open, and a cooking fire incident with no civilian injuries was recorded. The building's maintenance history indicates regular upkeep of windows, plumbing, and electrical systems, though the 2011 violations suggest there was a period requiring attention to safety systems that has since been addressed.

Risk rating

How 26-32 Isis 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.
