Initial analysis

The three-unit multi-family residential building at 450-454 Missouri Street in Potrero Hill, owned by Richard A & Janice M Fiore, is a two-story flats and duplex structure built in 1906. The property has undergone several significant maintenance and improvement projects over the years, with the most recent being a reroofing project valued at $25,000 scheduled for November 2024. Historical records show regular maintenance of critical building components, including the replacement of rear stairs in 2016 ($15,000), dry rot repairs in 2016 ($4,000), and earlier improvements such as aluminum window installation and kitchen cabinet updates in 1989, along with various dry rot repairs from 1988-1989.

The property has experienced some recent incidents requiring attention to the surrounding area, including a 2023 report of offensive graffiti (still open as of October 2023) and ongoing issues with vehicles blocking driveways, particularly during 2022-2024. There was also a report of a lifted sidewalk in 2022 (still open as of October 2023) and a hazardous materials incident involving glass on the street/sidewalk in 2021 (which was resolved). While these issues primarily affect the property's external environment rather than the building structure itself, they do represent some ongoing concerns for residents regarding access and neighborhood maintenance.

Risk rating

How 450-454 Missouri 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
