Initial analysis

The property at 304-306 17th Avenue in San Francisco's Central Richmond neighborhood is a 2-story, 4-unit multi-family residential building with ground-floor retail space, constructed in 1913 and currently owned by Raymond & Lana Hong Rev Trust. The building has undergone several maintenance and improvement projects over the past three decades, including a significant kitchen and bathroom remodel with window replacement in 2000, reroofing in 1995, and multiple siding repairs in 2018 and 2019, specifically addressing dry rot issues at the rear of the building.

Recent concerns have centered around the vacant commercial space, with multiple complaints filed between 2019 and 2024 regarding its unoccupied status and related registration issues. A notable sequence of maintenance challenges has emerged in late 2024 and early 2025, with recurring sewer discharge incidents from the side sewer vent recorded between November 2024 and January 2025, though these were subsequently resolved. There have also been several reports of garbage and debris issues, including human waste, during this period. The property has experienced some infrastructure challenges, as evidenced by a December 2024 complaint regarding lifted sidewalk tree roots affecting property maintenance. While there are recent complaints about garbage bins and utility access, these issues appear to be relatively isolated compared to the pattern of commercial vacancy complaints observed in recent years.

Risk rating

How 304-306 17Th 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.
