ADUs in West Seattle, Seattle
DADUs and attached units on West Seattle lots.
Slopes
Many lots slope, which affects foundations, drainage and the sewer route for a backyard unit. Steep slopes can also be mapped as environmentally critical areas with extra review.
Two units
Seattle allows up to two ADUs on a lot, so a basement unit and a cottage can both be on the table.
