Initial analysis

This Inner Richmond two-unit residential building, constructed in 1900 and currently owned by Joanne S & Harry Ja Wong 20, has undergone several significant structural improvements over the years, with the most notable being multiple foundation and structural reinforcements between 1989 and 2000, including concrete footing replacements, anchor bolting to the masonry foundation, and garage wall improvements. A reroofing project was completed in 2005, though records indicate this permit has since expired. The building has experienced some concerning recent activity, most notably a complaint filed in March 2024 regarding unpermitted construction work that had allegedly been ongoing for two years, though this complaint was promptly abated within two days. Additionally, there was a complaint about a possible illegal unit in the back of the house in 1997, which was also resolved.

The property has generated numerous 311 calls since 2022, primarily related to street cleaning issues, with a pattern of overflowed city garbage cans and general debris concerns outside the building. Between February 2022 and September 2024, there have been multiple reports of overflowing garbage cans and loose debris, with the most recent being garbage and debris complaints in September 2024. A Rent Board customer callback regarding fee housing inventory and unit count was resolved in January 2024, indicating compliance with housing regulations in that instance. While the building's structural maintenance history shows attention to foundational stability and safety over the years, the recent complaints about unpermitted construction work and the recurring garbage management issues in the vicinity suggest ongoing challenges with building maintenance and waste management practices.

Risk rating

How 349 10Th 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 1723 buildings in this neighborhood, 1292 are predicted to be safer.
