Initial analysis

The two-unit residential building at 850-852 31st Avenue in the Central Richmond neighborhood is a two-story flats and duplex structure, built in 1925 and currently owned by Matthew & Hannah Huey. The property has undergone several significant improvements over the years, with the most substantial renovations occurring in 2014, when the second floor received extensive upgrades including a kitchen remodel, new bathroom, lighting improvements, and electrical upgrades including the installation of a comprehensive electrical system with multiple circuits, dedicated appliance connections, and safety features like smoke and carbon monoxide detectors. Prior to this, the building received a new roof in 2007 at a cost of $15,450, and in 1990, repairs were made to address damaged stucco on the building's front facade.

A notable incident occurred in June 2014 when a complaint was filed regarding the construction of an illegal dwelling unit downstairs, though this complaint has since been marked as not active. The property has experienced some municipal service calls in recent years, primarily related to street-level issues such as parking violations (including a sidewalk parking citation in July 2022), general street cleaning needs, and a couple of abandoned vehicle reports on the street in 2019 and 2022, all of which were addressed by city services. While these external parking and street maintenance issues have occurred, they are more related to street conditions than directly impacting the building itself. The building's documented history shows regular maintenance and upgrades, with no recorded building code violations or safety concerns in recent years.

Risk rating

How 850-852 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

Out of 2250 buildings in this neighborhood, 1328 are predicted to be safer.
