Initial analysis

The two-unit multi-family residential building at 897 47th Avenue in the Outer Richmond, owned by Hudson Dennis John, has a documented history dating back to its 1924 construction. The property underwent termite and dry rot repairs in 1994 near the garage door area, which were properly completed. More recently, in January 2017, there was an electrical permit issued to address punch list items from a failed inspection, though this permit was ultimately cancelled, and the reasons for cancellation are not specified in the records.

The building has experienced several noteworthy incidents in the past year, with an unusual cluster of graffiti-related structural maintenance reports recorded between December 28, 2024, and December 28, 2024. There have also been multiple parking enforcement calls regarding illegal parking in the vicinity, with the most recent incidents occurring between December 11, 2024, and January 2, 2025. Additionally, there was one reported incident of garbage and debris (shopping cart) that was resolved promptly in December 2024. The property has had seven recorded false fire alarms, though it's important to note that none of these incidents resulted in civilian injuries. While the building's maintenance history shows attention to structural issues in the past, the recent cluster of graffiti incidents suggests there may be ongoing challenges with property maintenance in the surrounding area, though specific impacts on the building itself are not detailed in the records.

Risk rating

How 897 47Th 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

Out of 1040 buildings in this neighborhood, 634 are predicted to be safer.
