Initial analysis

The three-story, 8-unit apartment building at 985-999 Oak Street in Hayes Valley, owned by Chris and Cathy Giouzelis, has undergone numerous improvements and faced several significant issues since its construction in 1900. The property was identified as a Mandatory Soft Story Program participant in 2018 (as a Tier 4 building), and while this violation was officially marked as not active in 2024 with the Certificate of Final Completion issued, there was a period of non-compliance that drew attention in 2022-2023. The building has seen substantial renovation work in recent years, including the installation of a handicap-accessible bathroom in 2022 costing $20,000, multiple bathroom and kitchen renovations in 2020 with associated electrical and plumbing upgrades totaling over $125,000, and the addition of new skylights.

Historical records show earlier building violations from 2002 related to security and fire safety, including requirements for proper exit door hardware and removal of combustible storage, though these were all abated by July 2002. The property has maintained regular inspections since then, with the most recent routine housing inspection in 2008 and soft-story compliance inspections in 2022-2024. Recent activity in 2024-2025 has primarily consisted of street-level maintenance issues, such as debris removal and graffiti cleaning, as documented in several 311 calls, most of which have been resolved. The building's maintenance history shows generally proactive management, though the initial soft-story compliance issues and the substantial adjustment of project valuations in 2020 (from $850,000 to $35,000) suggest some complexity in project oversight during that period.

Risk rating

How 985-999 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.
