Initial analysis

The two-unit residential building located at 2831-2833 San Bruno Ave in the Portola neighborhood is a 1925 two-story structure with commercial space (Flat & Store) owned by Michelle Yip. The property has undergone several significant improvements over the past two decades, with the most substantial recent work being a comprehensive windows replacement and kitchen remodel completed in 2021 at a cost of $50,000, which included 13 new windows (four each in the front, back, and side) and various kitchen upgrades. The building's maintenance history shows attention to basic infrastructure needs, including multiple roofing projects (2000 and 2007) and electrical system upgrades, such as an underground service conversion to 100a with two meters completed in 2007 and a 220-volt copier machine outlet installation in 2004. A kitchen remodel was previously completed in 2007, accompanied by necessary electrical (new lighting and receptacles) and plumbing work.

The property has experienced recurring maintenance issues in its immediate vicinity, particularly in 2024-2025, with multiple reports of garbage and debris requiring city intervention (mostly resolving through Recology or Public Works services). There have also been several instances of non-offensive graffiti on and near the property in 2024, with most cases being resolved through city cleaning services, though one graffiti incident from May 2024 remains open as of the latest records. While these external maintenance issues are notable, they primarily affect the property's immediate surroundings rather than the building's internal conditions. A historical review shows one fire-related incident, though it was recorded as a false alarm with no injuries reported. The building appears to be well-maintained from a structural and systems perspective, with no recorded complaints or violations against planning codes or building permits.

Risk rating

How 2831-2833 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.
