Initial analysis

The two-unit multi-family residential building at 2748 San Bruno Avenue in Portola, owned by Tiffany Wei-ting Yee Irrevo, was constructed in 1919 and features two stories with commercial space. The property has undergone several significant improvements and faced some challenges over the years. Most notably, there have been recurring issues with the vacant storefront space, including recent complaints in 2023 and 2019 regarding non-compliance with the Vacant or Abandoned Commercial StoreFront Ordinance. The building experienced a minor incident in 2003 when a car damaged a corner of the structure, requiring repairs to approximately 200 square feet of stucco. Multiple renovation projects have been completed, including a substantial foundation modification in 2004 ($22,000), kitchen remodeling and bathroom updates in 2007 ($10,000), and various electrical upgrades between 2007-2014 including an underground service conversion in 2004. The property has maintained its basic infrastructure with historical permits showing reroofing work in 1989 and 2003.

Recent years have seen various 311 calls primarily related to parking issues, with multiple reports of blocked driveways between 2023-2025, though response officers were often unable to validate the violations. The most recent structural concern was in November 2024 involving a damaged Comcast utility vault. The building faced a brief violation in 2003 regarding unauthorized reroofing work, which was abated within three days. While the majority of historical permits and violations have been resolved, the recurring vacant storefront issue and recent service complaints suggest ongoing management challenges with the commercial portion of the property. The residential units appear to have received regular maintenance and upgrades over the years, including comprehensive electrical work and various interior improvements.

Risk rating

How 2748 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.
