Initial analysis

The 8-unit, 2-story multi-family residential building at 1230 Clayton Street in Corona Heights, owned by the Sanguinetti Family Trust, has experienced several significant structural and safety-related events since its construction in 1958. Most recently, in 2022, there was concern regarding the building's structural stability at the ground floor, with suggestions that it should be added to the soft-story inventory list. This followed a pattern of structural issues, including a notable incident in July 2011 when a vehicle crashed into the building, removing approximately 14-15 vertical framing members and causing significant damage that required $20,000 in repairs. The building has undergone several major maintenance projects, including balcony replacements (2007), deck repairs (1999), termite damage repairs (1993), and reroofing work (1988). Multiple violations and complaints have been recorded over the years, though most have been resolved. These include issues with exterior door self-closing devices, a defective catchbasin coverplate, and various safety concerns addressed through routine apartment inspections. While there have been recurring fire-related complaints regarding extinguishers and blocked exits between 2017 and 2024, all were determined to have no merit. Recent 311 calls from late 2024 indicate ongoing maintenance needs in the surrounding area, though these are not directly related to the building's condition.

Risk rating

How 1230 Clayton 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 348 buildings in this neighborhood, 299 are predicted to be safer.
