Initial analysis

The two-unit residential building at 483-485 28th Avenue in San Francisco's Central Richmond neighborhood is a two-story flats and duplex structure built in 1919 and currently owned by the Chan Family Trust. The property underwent significant renovations in 2009-2010, including major bathroom and kitchen remodeling on all floors, the addition of new full bathrooms and master bathrooms, and foundation repairs in the first-floor corridor. This comprehensive renovation, valued at $60,000, was accompanied by electrical upgrades to 200-amp service with three meters, plumbing work for new bathrooms and kitchens, and the installation of additional bathroom facilities across the building. The property has a documented history of stairway lift installations between 1988-1992, indicating previous accessibility modifications.

The building's recent history shows several concerns related to parking issues, with multiple reports of sidewalk parking between 2019 and 2024, though enforcement actions have typically resulted in either citations or officers being unable to locate the offending vehicles. Other minor issues included a noise complaint in 2019 and a toter management issue in 2019 that required outreach and enforcement. The most recent incident involved abandoned electronics on the street in August 2024, which was resolved by Recology. The building's maintenance and systems appear to be modernized and in compliance, given the comprehensive nature of the 2009-2010 renovations and subsequent completed permits for various improvements.

Risk rating

How 483-485 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, 518 are predicted to be safer.
