Initial analysis

The two-story multi-family residential building at 425 Fair Oaks Street in Noe Valley, owned by the Duffy Frank & Monica Trust, was constructed in 1961 and contains four units. The property has undergone several significant maintenance and compliance updates over the years, including reroofing work in 1989, hot water heater lining in 1987, and various code compliance improvements completed in 1984. A concerning incident occurred in 2006 when a complaint was filed regarding deteriorating paint conditions at the front property line wall, with the potential implication of lead-based paint due to the building's age; this violation was resolved by October 2006. The building has been subject to regular routine inspections by Housing Inspection Services, including assessments in 2002 and 2009, though no significant violations were noted during these inspections.

In more recent years, the property has primarily experienced issues related to parking and vehicle access, with multiple reports of blocked driveways between 2019 and 2020, some resulting in citations being issued. There have been two scooter-related incidents recorded this past year (2022-2023), though these appear to be more related to street conditions than building-specific issues. The building's permit and violation history suggests that major building systems have received appropriate maintenance attention over the decades, with no unresolved building code issues currently on record. The property's infrastructure improvements, such as the completed hot water heater lining and reroofing work, indicate basic building systems maintenance has been historically addressed, though recent maintenance history is less documented in available records.

Risk rating

How 425 Fair Oaks 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

Out of 1879 buildings in this neighborhood, 1015 are predicted to be safer.
