Initial analysis

The two-unit residential building at 459-461 28th Street in Noe Valley, owned by the Chew-dea Trust, was constructed in 1986 and completed in 1988. The two-story structure has undergone several permitted improvements over its lifetime, including a kitchen remodel completed in 1990, following an earlier kitchen renovation that expired in 1988. Historically, the building's significant improvements have been properly documented through building permits, with no major structural changes or code violations recorded in recent years.

The property is currently experiencing recurring issues with illegal parking and sidewalk obstructions, particularly in 2023, with multiple incidents involving the same BMW vehicle (license plate 9DMC351) parking violations between May and September 2023. These incidents have generally been addressed through parking enforcement actions, resulting in citations and warnings, though there were also some instances of administrative closures due to age of requests. Recent parking-related complaints have included various vehicle types and situations, suggesting ongoing challenges with parking compliance in the immediate vicinity, while not directly affecting the building's structural integrity or habitability. The most recent issue occurred in October 2023, demonstrating that parking enforcement remains an active concern in the neighborhood.

Risk rating

How 459-461 28Th St'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.
