City council has proposed significant changes to the Seattle Land-Use Code with the aim of increasing the construction of backyard cottages (DADUs) and attached accessory dwelling units (ADUs). These changes, in the making for years now, have been delayed by a lawsuit and appeal brought about under SEPA regulations. Seattle City Council held a public hearing to discuss the proposed code changes Tuesday, June 11th at 5:30pm in council chambers. Discussion and possible vote on amendments and the proposed legislation will be held on June 28th at 2:00pm.
What do these changes really mean for Seattle and for ADUs?
The proposed code changes include many items that are minor and could have been completed years ago. These include modest increases in size and height of allowed cottages, details about dormers, and the location of entries. The more significant changes proposed are as follows:
Allowing two ADUs on one lot
Removing the off-street parking requirement
Removing the owner-occupancy requirement
Increasing the household size limit for a lot with two ADUs
Establishing a new limit on the maximum size of single-family dwellings equal to one half of the lot size (FAR = 0.5)
