The Humboldt Apartments, located in downtown Santa Rosa and designed by Jon Worden Architects, is a five-story mixed used midrise comprised of ground floor retail and office space and private garage, and 52 rent-regulated affordable one, two and three bedroom apartments, together with an elevated podium garden.

The striking mural on the north façade of the buildings was rendered by Jon Worden and inspired by the sculptures of the Norwegian sculptor Gustav Vigeland.
