Initial analysis

The two-unit residential property at 359 31st Avenue, located in San Francisco's Central Richmond neighborhood, is a two-story duplex built in 1987 and currently owned by the Chan Philip & Emmy Trust. The building underwent significant early modifications in 1986, including the demolition of a previous structure and the installation of a fire sprinkler system, along with raising the basement floor level by 4 to 6 inches. Subsequent permitted work included a reroofing project in 1998 and an external work order in 1989, though both of these permits have since expired.

In terms of resident experience and safety, the most prominent current issue involves recurring problems with blocked driveways, with ten documented incidents between 2023 and 2024. While most of these cases resulted in police responses, only one citation was issued (to a black Toyota Prius on July 3, 2023), and several resulted in "Unable to Locate" outcomes, meaning the offending vehicles were not present when enforcement arrived. Two cases were deemed invalid due to incomplete reporting information, and one case from August 2023 resulted in an advisory citation. The relative frequency of these parking issues suggests a persistent challenge in the vicinity, though it's worth noting that these enforcement actions are typically outside the building's direct management control.

Risk rating

How 359 31St Ave'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
