⭐ General DADU Guidelines for Seattle Homeowners

If you’re considering a backyard cottage (DADU) in the Seattle area, here are the basic rules most homeowners should know:

✔ Up to ~1,000 sq. ft. allowed

Most Seattle lots allow a DADU up to around 1,000 square feet, depending on the property size and zoning.

✔ Standard zoning rules apply

Your DADU must follow typical requirements such as setbacks, lot coverage limits, and height restrictions.

✔ Permits and plans are required

You’ll need a site plan, architectural drawings, and in many cases, structural engineering for approval.

✔ No off-street parking required

Seattle has made backyard cottages easier to build by removing the old parking requirement.
