Initial analysis

The 4-unit multi-family residential building at 2791-2793 San Bruno Ave, owned by Michael S. Wong and Kath Jiang, was constructed in 1965 and is situated in the Portola neighborhood. The property has undergone several significant modifications and improvements over the years, with the most recent major work being a reroofing project completed in 2017 at a cost of $11,805. In 2004, the building underwent a substantial transformation from a real estate office to a chiropractic office, including moving the front door to the property line and making additional changes at a cost of $50,000, followed by the installation of security gates and various electrical upgrades. The building has experienced two notable periods of violations, first in 2001 and then in 2007, primarily related to safety and maintenance issues including fire escape maintenance, smoke detector installation, and security features. All these violations were resolved by mid-2001 and late 2007 respectively.

More recently, the building's surroundings have been the subject of multiple 311 calls in late 2024 through early 2025, primarily regarding sanitation issues with reports of garbage and debris on and around the property, though many of these cases were resolved quickly with no work needed or through standard cleanup procedures. The property has maintained regular housing inspections throughout its history, with the most recent routine inspection occurring in 2010, while the building's infrastructure improvements, including the conversion from overhead to underground service, indicate ongoing maintenance and upgrades to the property's essential systems. The building's maintenance history shows a pattern of addressing violations promptly, though the recent accumulation of sanitation-related 311 calls suggests ongoing challenges with waste management in the immediate vicinity.

Risk rating

How 2791-2793 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
