Initial analysis

The 3-unit, 2-story multi-family residential building at 350 28th Avenue in the Central Richmond neighborhood, owned by the Chin-Cheong Family Trust, was constructed in 1984-1985 and has undergone several significant improvements over its lifetime. The building has been well-maintained with regular updates to its systems and units; most notably, there were substantial kitchen renovations in 2007-2008 across multiple units, including new countertops, appliances, and fixtures, with associated electrical and plumbing work. More recent improvements include a water heater replacement in 2015, suggesting continued maintenance attention from the owners.

The property experienced some infrastructure challenges between 2012-2022, including three documented sewage backup incidents (two in 2012 and one in 2022) and four pavement defect reports between 2012-2013. While these issues were addressed through various city repair processes, they indicate some historical infrastructure vulnerability in the surrounding area. The most recent building-related events include a 2024 garbage debris incident and two 2022 general cleaning issues, though these were primarily street-level concerns rather than building-specific problems. The building's history shows a pattern of regular maintenance and updating, with no recent major building code violations or safety concerns on record.

Risk rating

How 350 28Th 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
