Initial analysis

The three-story, six-unit multi-family residential building at 333 Webster St in Hayes Valley was constructed in 1906 and is currently owned by Kristen Quan. The building has experienced several significant events, with the most pressing being its active compliance issues regarding the Soft Story retrofit program. Although the property was confirmed as having completed the retrofit work with a Certificate of Final Completion (CFC) issued, there was a formal complaint filed in October 2019 regarding failure to obtain the necessary permits and complete associated work, which drew attention to the building's seismic safety obligations.

The building's recent history shows mixed maintenance and improvement efforts. In 2020, there was an attempt to add an ADU dwelling unit at ground floor level (valued at $220,000), but this permit was ultimately cancelled. Prior to these, the building underwent a successful soft story retrofit in 2017 (costing $94,000), and previous renovation work in 2001 included multiple interior improvements to apartments and common areas. The property experienced various maintenance challenges in the early 2000s, including water damage repairs, electrical issues, and multiple complaints about heating systems, which were subsequently addressed. Historical records show earlier improvements, such as reroofing in 1997 and window replacements in 1989. The building's recent tree maintenance needs were handled by the Department of Public Works in 2019, with cases being resolved through tree removal. While the property has had its share of maintenance issues and compliance challenges, many have been addressed through appropriate channels, and the building is currently listed as having completed its Soft Story retrofit requirements.

Risk rating

How 333 Webster 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.
