Initial analysis

The two-unit multi-family residential building at 470-472 16th Avenue in the Central Richmond neighborhood, owned by Lam Wai Yee, is a two-story flats and duplex structure built in 1979. The building has undergone several significant renovations and repairs over the past few decades, with the most recent major work being a cancelled reroofing project in 2021 that had an estimated cost of $9,000. In 2017, completed improvements included replacing the stucco wall, windows, and garage door with $7,000 worth of updates that featured new fiberglass windows visible from the street. An electrical upgrade in 2011 added a house meter for common area use, and earlier modifications included basement renovations in 2000 that added a bathroom, closet, and new bedroom ($5,000). The building's history also reveals several attempts to address unauthorized modifications, including cancelled permits in 1984-1985 related to reverting the property to its intended two-family dwelling use and legalizing existing bathroom facilities.

Recent activity around the property has primarily involved street-level issues rather than building-specific concerns, with multiple reports of abandoned vehicles, sidewalk parking violations, and an incident involving medical waste (needles) on the street in 2021, which was promptly addressed by city services. While these external issues have been documented through 311 calls, they do not directly reflect on the building's condition or management. The property has maintained compliance with required permits and inspections, as evidenced by the "complete" status of most major permits and the resolution of street-level complaints through appropriate city agency responses.

Risk rating

How 470-472 16Th 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.
