Initial analysis

The two-unit, two-story multi-family residential building at 420 Fair Oaks St in Noe Valley, owned by Rodolfo L Padilla 2010 Living Trust, has been standing since 1906 and has undergone several significant infrastructure updates. Most notably, in 2020, a major electrical system upgrade was completed with the installation of a new 200 amp, 3-meter main service. The building's maintenance history shows attention to basic upkeep, with window replacements in 2002 and reroofing work in 1991, though these permits have since expired.

Recent history indicates some maintenance challenges, particularly regarding the building's sewer system, with documented sewage backup incidents in both February and November 2022, and most recently in November 2023. A noteworthy building complaint was filed in March 2021 regarding an unpermitted rear ADU construction project that was reportedly built right up to the property line, though this case has since been marked as not active. The surrounding area has experienced recurring issues with parking violations, including vehicles blocking driveways and parking on sidewalks, with citations being issued in several cases between 2021 and 2024. While there have been multiple reports of abandoned vehicles in the vicinity between 2022 and 2023, these situations were generally resolved promptly, with no vehicles found upon inspection.

Risk rating

How 420 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.
