Initial analysis

The two-unit residential building at 3237-3239 San Bruno Avenue in Visitacion Valley, owned by Tan Can Chuan & May Lee, was constructed in 2011 following several years of permitting and construction activities that began in 2007. The building is a two-story flats/duplex structure that underwent significant modifications during its construction phase, including plumbing installations for multiple bathrooms and kitchens, electrical work for a 200amp service with three meters, and HVAC system installation with gas furnaces and ductwork. Several street space permits were issued between 2009-2010, indicating work that required temporary use of the public right-of-way.

The property has experienced two notable building complaints between 2011-2012, both related to unauthorized modifications including the conversion of common areas into additional units, though these complaints were subsequently abated. More recently, from late 2024 to early 2025, there has been a pattern of street cleaning and garbage management issues near the property, with multiple reports filed regarding garbage and debris, though most of these cases were resolved promptly. The most recent activity involves an open Shared Spaces request from January 2025 concerning waste management and temporary facilities, but this appears to be related to external activities rather than the building itself. While the building's original construction and systems installations were properly permitted and completed, the historical unauthorized modifications and recent external cleaning issues represent the property's most significant points of concern.

Risk rating

How 3237-3239 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

Out of 214 buildings in this neighborhood, 167 are predicted to be safer.
