Initial analysis

3227-3229 San Bruno Ave is a two-unit, two-story multi-family residential building located in Visitacion Valley, constructed in 2011 and currently owned by Wendy Wu. The building underwent significant construction and improvement work in 2009-2010, including major plumbing and electrical system installations featuring seven bathrooms, two kitchens, two laundry facilities, and separate utility meters. Several street space permits were issued between 2007 and 2010, indicating proper municipal coordination during the building's setup.

Of particular note are two building code violation complaints filed in 2011-2012 regarding an unauthorized conversion of common areas into living space, specifically involving laundry facilities relocated to the garage area. These violations were subsequently abated. The property has experienced various maintenance and infrastructure issues in recent years, with multiple 311 calls between 2021-2025 reporting problems such as sidewalk defects, graffiti, and debris. The most recent issues reported in 2023 include a sidewalk defect and a curb ramp defect, though these were marked as duplicate complaints. A garbage and debris complaint was also logged and resolved in January 2025.

Risk rating

How 3227-3229 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.
