Initial analysis

The three-unit multi-family residential building at 4317 Irving Street in San Francisco's Outer Sunset neighborhood, owned by Fan Yu Hom Trust, is a two-story flats and duplex structure built in 1949. The building's maintenance and service history shows relatively few significant issues, with the most substantial plumbing work recorded being an attempted installation of a new central forced air heating unit and flexible gas pipe in unit 4319 in July 2016, though this permit is now shown as expired. While the property has experienced multiple parking enforcement incidents between 2017-2024, including three confirmed citations for blocking driveways in June 2018 and one more recent case in June 2024, these are common urban challenges rather than building-specific issues. The building faced one instance of offensive graffiti in August 2020, which occurred during the pandemic and was subject to deferred inspection due to Shelter-in-Place restrictions. Other service calls were primarily related to street maintenance matters including tree pruning (July 2017), general street cleaning (July 2017), and waste removal (September 2017), which were all resolved appropriately. A tipped-over litter receptacle was reported in February 2019, though this was determined to be on private property.

Risk rating

How 4317 Irving 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
