Modern ADU in Altadena

This ADU in Altadena is finished in smooth taupe stucco with white window frames and a pitched roof. The tall side of the building rises two stories, with windows on both floors and a wide sliding glass door at ground level that opens onto a new concrete patio. Black wall sconces sit beside the doors, and a tankless water heater is mounted on an outside wall. A lower one-story section at the back has a plain white entry door and two small horizontal windows.

The yard has mature trees and hedges on the property lines. Along one edge of the patio, an old stacked stone retaining wall holds back the slope, and a gravel strip runs between the wall and the new concrete. The photo gallery below shows the exterior and yard of this Altadena ADU.
