Initial analysis

The Wong Revocable Trust owns this two-unit residential building, a two-story flats and duplex structure located at 522-524 46th Avenue in San Francisco's Outer Richmond neighborhood. Built in 1948, the property has undergone several significant modifications over its lifetime. In 1989, two major improvements were completed: a horizontal addition and a comprehensive kitchen remodeling project on the second floor that included new cabinets, tile work, flooring, plumbing, and electrical updates. However, it's worth noting that a reroofing permit issued in December 1988 expired without completion.

In more recent years, the building has experienced some regulatory scrutiny. In December 2020, there was a noise complaint regarding construction work being conducted without permits, which was investigated and closed within a few weeks. This followed a similar incident in 2010 when there were allegations of an unauthorized in-law unit being constructed behind the garage, though this complaint was promptly addressed within five days. Additionally, there is a record of front yard paving work being completed at 522 46th Avenue, though it is unclear if this was part of the previously mentioned unpermitted construction activity. While the building has maintained its residential classification as a multi-family dwelling, these incidents suggest occasional challenges with permit compliance and construction activities at the property, though all reported complaints have been officially closed or abated.

Risk rating

How 522-524 46Th 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.
