Augrented Insights

Initial analysis

The two-unit residential building at 452 4th Avenue in the Inner Richmond neighborhood, owned by the Richard Fague Trust, is a 2-story flats and duplex structure constructed in 1910. The building's maintenance record shows minimal plumbing work, with the only documented permit being the replacement of a gas water heater in June 2010, which has been properly completed.

The property has experienced recurring issues with graffiti in the surrounding area over the past decade, with three documented incidents on or around utility poles between 2013 and 2020, all of which were classified as offensive and subsequently resolved. The most recent activity related to the building was a valid mailing request to the Rent Board for fee housing inventory information in January 2024, which has been processed and marked as resolved, with confirmation that the requested form will be mailed out within the week. While the historical graffiti incidents indicate some neighborhood maintenance challenges, it's worth noting that these occurred primarily on public infrastructure rather than the building itself. The property's documented history shows regular administrative engagement with San Francisco housing authorities, particularly in regard to the Rent Board.

Risk rating

How 452 4Th 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

71th percentile

Out of 1723 buildings in this neighborhood, 500 are predicted to be safer.
