Initial analysis

The three-unit residential building at 3090 San Bruno Avenue in the Portola neighborhood, owned by Eng Nelson A & Denh C V Rev, was constructed in 1989 and features three stories. More recently, the property has undergone several notable improvements, including a reroofing project completed in July 2024 costing $11,000, and the replacement of a backyard window in February 2024 to meet inspection requirements. A significant legalizations project in 2014 (costing $24,000) legalized a first-floor dwelling unit, including a bedroom, kitchen, bathroom, and media room, along with the addition of bicycle parking and a new street tree. The building's infrastructure has been maintained through various permitted improvements, including kitchen relocations and remodels (completed in 2015) with corresponding electrical and plumbing updates.

Recent records from January 2025 show multiple reports of roadside debris and garbage issues near the property, with several cases resolved by city services or Recology, including instances involving furniture, a mattress, and yard waste. While these cleanup incidents suggest some ongoing maintenance challenges in the immediate vicinity, it's worth noting that most cases were promptly addressed and reported as resolved. The building's original construction included fire safety measures such as sprinklers, and there is one recorded incident involving outdoor rubbish fire, which resulted in no civilian injuries. The property's documented history shows regular maintenance and improvements, with all major renovations properly permitted and completed according to city records.

Risk rating

How 3090 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.
