Initial analysis

The two-unit residential building at 454-456 28th Avenue in San Francisco's Central Richmond neighborhood is a two-story flats and duplex structure built in 1984, currently owned by Michael T C Ma 2014 Revoc T. The property's documented history shows several key construction and maintenance milestones, beginning with demolition work that was unfortunately cancelled in 1983, followed by completed framing revisions to permit a sub-basement in early 1984. The building was officially constructed later that same year. In November 2000, the property underwent a significant improvement with a completed $8,000 re-roofing project.

The only recorded non-construction-related incident was a street cleaning matter in May 2018, which involved loose garbage on the street or sidewalk and was promptly resolved by the Department of Public Works. This external cleanliness issue appears to have been an isolated incident with no apparent impact on the building's condition or habitability. The available records suggest regular maintenance of the property, with no ongoing concerns or safety issues noted in either the building permit or 311 call databases.

Risk rating

How 454-456 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

Out of 2250 buildings in this neighborhood, 338 are predicted to be safer.
