Initial analysis

The four-story, three-unit multi-family residential building at 404 Oak Street in Hayes Valley, owned by Steve F Bruhns, was constructed in 1900 and has undergone several significant maintenance and improvement projects over its lifetime. The most substantial renovation occurred in 1986 when all three kitchens and bathrooms were remodeled, along with the addition of handrails and stair repairs. More recently, in 2007, there was a plumbing violation related to unauthorized installation of copper piping and a direct vent heater, though these were resolved within three months. The building has undergone routine safety inspections by Housing Inspection Services in 2003, 2004, 2009, and 2018, with no indicating cause for concern.

In the past year, between September 2024 and January 2025, there have been multiple reports of garbage, debris, and sidewalk cleaning issues in the vicinity of the building, with most cases being resolved promptly. There was also a fire-related complaint in 2014 regarding operation without a permit, which was corrected by 2015. The building has experienced several activation events related to its alarm and fire safety systems, though all were confirmed to be either false alarms or due to malfunction, with no civilian injuries reported. Two rejected planning applications for group housing for a religious order were filed in the early 2000s, and the building's unit count was corrected from 2 to 3 in a Rent Board inquiry in October 2024.

Risk rating

How 404 Oak 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

Out of 1027 buildings in this neighborhood, 544 are predicted to be safer.
