Initial analysis

The two-story multi-family residential building at 2491 San Bruno Avenue, owned by Richard J. Traverso, has undergone several significant infrastructure improvements since its construction in 1900. Most notably, the property has experienced recurring sewer system issues, with documented sewage backup discharges from the side sewer vent in both December 2024 and January 2025, following a previous main sewer line replacement in 2016. The building's maintenance history includes a substantial reroofing project completed in 2018 costing $18,500, water service work in 2019, and a 200-amp electrical underground conversion completed in 2007, indicating efforts to maintain and upgrade essential systems.

The property has recently faced multiple challenges related to graffiti and sewage issues, with five reported graffiti incidents (three unresolved as of early 2025) and two sewage discharge incidents in late 2024-early 2025, which were resolved through field work. Additional infrastructure improvements on record include a main sewer line and house trap replacement in 2016, suggesting ongoing attention to plumbing systems. The building previously housed a freestanding Clear Channel Outdoor sign that required compliance adjustments in 2009, and there are documented sidewalk issues attributed to tree root lift, though this was identified as a duplicate report in late 2024. While the property has experienced some infrastructure challenges, the owner has generally addressed maintenance needs through appropriate permits and work completion.

Risk rating

How 2491 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 255 buildings in this neighborhood, 168 are predicted to be safer.
