Initial analysis

The property at 3207-3209 San Bruno Ave is a two-unit, two-story multi-family residential building constructed in 2011. The building has experienced several significant incidents, most notably two vehicular collisions in 2011 and 2022 that caused substantial damage to the structure. The 2011 incident resulted in damage to the garage area, including compromised gas and electrical lines, requiring extensive repairs to the sidewalk, siding, and fence, along with gas line replacements and electrical system checks. The more recent 2022 incident caused damage to a ground floor wall, affecting utilities, and required repairs to a party wall and interior shear wall. This incident also revealed underground gas/diesel containers that have been the subject of recent complaints regarding potential safety concerns due to truck traffic causing vibrations.

The building's infrastructure has undergone significant upgrades and maintenance over the years, including electrical system improvements (replacement of 200-amp panels in 2022, installation of new electrical service in 2010), plumbing work (waste line and sink drain repairs in 2022, gas line replacements in 2011), and various structural repairs. A 2023 complaint raised concerns about the underground gas/diesel containers, while a 2021 complaint noted issues with light pollution from nearby flood lights. The building has also experienced plumbing issues, including a significant sewer pipe failure in late 2022, and there was a period of illegal unit conversion behind the garage that was addressed in 2011-2012. Recent 311 calls from late 2024 have primarily concerned street cleaning issues near the property.

Risk rating

How 3207-3209 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.
