Initial analysis

The two-unit, two-story residential building at 3971-3973 26th Street in Noe Valley, owned by Sheila Dillman, was constructed in 1922 and has undergone several significant improvements over the past 25 years. Most recently, there have been multiple sidewalk-related issues, with the earliest 2024 report noting a collapsed sidewalk, and a similarly concerning lifted sidewalk issue in October 2023 that was temporarily resolved but continues to represent potential hazard. The building has received proper maintenance attention, including a $11,300 re-roofing project completed in 2016, and underwent substantial structural improvements in 2000 when two walls on the first floor were modified with steel framing and two garage posts were replaced with a steel beam, a project costing $60,000. Earlier enhancements include a kitchen remodel in 2003 featuring new cabinets, countertops, and extensive electrical updates, as well as an expired permit from 1998 for re-roofing work. The building's infrastructure has been maintained reasonably well, though the recurring sidewalk issues suggest ongoing attention is needed for public safety.

Risk rating

How 3971-3973 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.

Neighborhood percentile
87th percentile

Out of 1879 buildings in this neighborhood, 244 are predicted to be safer.
