Initial analysis

The 2507-2509 San Bruno Avenue property is a two-unit, two-story multi-family residential building with a commercial space, located in the Portola neighborhood and constructed in 1907, currently owned by the Leung/yu Family Trust. The building has undergone several significant improvements over the past two decades, including a conversion from overhead to underground electrical service with a 200-amp system installed in 2003, sewer main repairs in 2008, a re-roofing project in early 2013, and a kitchen remodel later that same year. Of particular note is a building complaint filed in May 2023 regarding the main building being vacant, though this complaint is currently listed as not active.

In recent months (December 2024 - January 2025), the property vicinity has experienced multiple maintenance issues primarily related to street cleaning, with at least ten reports of garbage, debris, and graffiti on or near the property. The majority of these reports have been resolved through inspection and appropriate action, including one noted instance of a posted Notice of Violation for sidewalk graffiti. Historical building maintenance records show a pattern of systematic upkeep, with the most recent substantial work dating back to 2013. While the building has maintained basic safety and structural improvements through various permits, the recent cluster of street-level issues suggests ongoing challenges with property maintenance in the immediate surroundings.

Risk rating

How 2507-2509 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

Out of 255 buildings in this neighborhood, 196 are predicted to be safer.
