What can I build on my Seattle Neighborhood Residential property? Case 2: Single Family Home with Accessory Dwelling Units
Seattle's Neighborhood Residential zones-until recent years known as Single Family zones-occupy about 72% of Seattle's land area. To accommodate growth and provide more housing options for residents with a wide range of incomes, Seattle's Land Use Code now allows greater density and housing types, including houses, accessory dwelling units, townhouses, and even up to 6 units of apartments in these areas formerly restricted to single family homes.
These site diagrams show the allowable size, location, and number of Accessory Dwelling Units allowed on a property. There are different requirements and allowance between Attached Accessory Dwelling Units (AADU's) and Detached Accessory Dwelling Units (DADU's), as well as different restrictions on sites with and without abutting alleys.
