Initial analysis

The three-story, six-unit multi-family residential building at 867-877 Oak Street in Hayes Valley, owned by Siu Family Trust, has undergone several significant changes since its construction in 1905. Most recently, there were two active building violations filed in December 2024 regarding blocked egress paths at fire escape stairs and a malfunctioning doorbell in one apartment. A notable incident occurred on June 17, 2024, involving a building fire that reportedly left damage that has not yet been addressed. The building completed its mandatory soft-story retrofit program (Tier 3) in 2022 after receiving several citations for non-compliance dating back to 2020, and has recently undergone gas line upgrades with the installation of six new gas lines in June 2023. Previously, there was an attempt to add two accessory dwelling units in 2020 to increase the total from six to eight units, though the status of this permit remains filed as of 2023.

The property has a history of various compliance and safety-related issues, including a 1990 case where an illegal unit was removed and restored to storage use, and a 2002 complaint regarding multiple violations that required attention to gas meters, deck repairs, combustible storage, and gas utility shutoff tools. While the building has made progress in some areas, such as completing the soft-story retrofit, the recent fire incident and unresolved building violations suggest ongoing maintenance and safety concerns. The property has also experienced periodic issues with sidewalk parking violations and loose garbage in the vicinity, as evidenced by multiple 311 calls between 2021 and 2023, though these appear to be primarily external to the building itself.

Risk rating

How 867-877 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.
