Initial analysis

The property at 2848-2850 San Bruno Ave is a 1-story, 2-unit multi-family residential building located in the Portola neighborhood. The building, owned by Soo Stanley Yu, was constructed in 1950 and has undergone several renovations and improvements over the years. Most notably, in 2022, a 2.7 kW solar PV system was successfully installed on the roof, representing a significant upgrade in energy efficiency. Recent maintenance includes a window replacement project filed in 2020, though the permit status remains as "Filed." The building has a history of proper maintenance, with multiple roof replacements documented in 1991 and 2006, and various interior improvements completed in the 1990s including kitchen remodels and sheetrock work.

The property has experienced some maintenance and environmental challenges in recent years, particularly in 2024, with multiple reports of graffiti on and near the property, primarily affecting public sidewalks. There was also one report of garbage and debris in November 2024, though this was resolved. The building's infrastructure has seen significant improvements over the years, including an underground electrical conversion in 2004 and the installation of a self-service water machine in 2003. A building complaint was filed in 2001 regarding unpermitted window installations, but this was promptly abated within three weeks. The property has maintained a relatively good record regarding building and electrical permits, with most major work being properly permitted and completed. The most recent permit activity suggests ongoing improvements to the building's exterior and systems, though some permits from 1994-2006 show as expired rather than completed in the records.

Risk rating

How 2848-2850 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.
