Initial analysis

The four-unit, two-story multi-family residential building at 406 London Street in the Excelsior neighborhood, owned by Jesus & Herminia Garcia, has a relatively stable history since its construction in 1906. The most significant recent building modifications occurred between 2005-2006, when substantial ground floor renovations were undertaken, including the addition of bedrooms, hallways, bathrooms, and storage rooms, with a total cost of approximately $40,000. These improvements were accompanied by an electrical upgrade that included the installation of a 70-amp subpanel, lighting, switches, and receptacles, which was successfully completed. A brief building complaint regarding an unauthorized room in the garage was filed and resolved within one day in March 2006.

More recent history from 2023-2024 has been marked by routine urban maintenance issues rather than structural concerns. There have been multiple reports of street cleaning needs, including loose garbage and debris, and several incidents of vehicles blocking driveways that resulted in citations. Tree maintenance has been a recurring issue, with overgrown trees reported blocking signs in mid-2024. Three cleaning or maintenance-related 311 calls were received in 2024 alone, two of which involved overgrown trees. The only recorded fire-related incident was a water-related issue with no civilian injuries. While the building's major systems have been upgraded and there have been no recorded safety incidents, the property is currently experiencing typical urban maintenance challenges related to street cleaning and tree maintenance.

Risk rating

How 406 London 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 337 buildings in this neighborhood, 276 are predicted to be safer.
