Initial analysis

1670 Clay Street is a 14-unit, 4-story multi-family residential building located in Nob Hill, owned by the Garret & Anita Tom Trust and constructed in 1910. The property underwent significant improvements in recent years, including mandatory seismic retrofitting as a Tier 3 soft-story building, which was completed with the addition of two new ground floor units, sprinkler systems, and various building upgrades. Major safety enhancements included a comprehensive fire alarm system upgrade completed in 2020, installation of low-frequency sounders, and regular maintenance of fire extinguishers and sprinkler systems, with the most recent fire safety corrections documented in 2022.

The building has faced multiple challenges over its history, with the most concerning issues arising in 2018 when there was a period of significant maintenance deficiencies affecting tenant comfort and safety, including heating system failures, plumbing problems, and various building envelope issues. These were addressed through subsequent repairs and upgrades, including extensive electrical work in 2017 to install new panels, receptacles, and address system deficiencies. Historical complaints from the late 1990s show previous concerns about windows, electrical systems, and building maintenance, though these were resolved at the time. The property underwent various infrastructure improvements including reroofing in 2015, and has maintained compliance with most building codes since completing its seismic retrofit requirements, as evidenced by receiving its Certificate of Final Completion (CFC).

Risk rating

How 1670 Clay 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.
