Initial analysis

The two-unit multi-family residential building at 2511 San Bruno Avenue, located in the Portola neighborhood, was constructed in 1910 and includes a street-level commercial space as part of its flat building configuration. The property has undergone several notable improvements over the years, with the most recent being an electrical upgrade in October 2022, where a 60-amp Federal Pacific subpanel was replaced with a new Siemens subpanel. This followed earlier infrastructure work including an underground electrical service conversion completed in 2003 and a commercial space renovation in 2007 that transformed a retail space into a hair salon with new fixtures and restroom improvements.

The property has experienced numerous maintenance and cleanliness issues in the surrounding area in recent months, particularly between December 2024 and January 2025, with multiple reports of garbage and debris on the street and sidewalk. There were also three separate instances of public graffiti reported in this period, affecting both the sidewalk and a parking meter, with one graffiti case still marked as open. While these external maintenance issues were generally addressed promptly by city services and Recology, they occurred frequently over a short period. The building itself appears to be structurally sound based on available data, with no recorded serious safety or habitability issues in recent years.

Risk rating

How 2511 San Bruno Ave'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
