Initial analysis

The property at 3409-3411 Irving Street in San Francisco's Central Sunset neighborhood is a two-story, two-unit multi-family residential building constructed in 1945, currently owned by the Tong Trust. The building's maintenance record shows one significant structural maintenance activity, with a complete reroofing project undertaken in 1999.

More recently, the property has experienced a series of concerning sewer-related incidents, with four documented sewage back-up discharge events from the side sewer vent occurring between November 2024 and January 2025, all of which required intervention from PUC Sewer Operations and were marked as resolved through field work. The building's immediate vicinity has faced challenges with urban debris management, particularly in late 2024, with multiple reports of abandoned furniture and other debris on the street and sidewalk (including incidents on November 12, 2024, involving a mattress and several furniture items). The most recent incidents include a blocked sidewalk case involving an unlicensed scooter in January 2025, representing a minor mobility concern.

Risk rating

How 3409-3411 Irving St'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.
