Accessory Dwelling Unit Code Update

 

We want your feedback for the ADU Code Update!

The City of Edmonds is proposing to increase allowances for accessory dwelling units to better align with the needs of Edmonds' residents, particularly the increasing interest to ‘age in place.’

We are actively seeking public thoughts and opinions on the draft code amendments prior to the City Council Public Hearing on May 7th.

The draft code and updated slide show were developed based on the November 30th live webinar, previous public comments, and guidance from the Planning Board.

What are Accessory Dwelling units?

An accessory dwelling unit is a small residence that shares a single-family lot with a primary dwelling.

An ADU is self-contained, with its own kitchen or kitchenette, bathroom, and living/sleeping area.

  • An attached ADU is a dwelling unit located within or attached to another housing unit.
  • A detached ADU (DADU) is separate and unconnected to the other housing unit.

Edmonds currently allow accessory dwelling units attached to or constructed within the primary residence in all single-family residential zones (except within Planned Residential Developments) with a conditional use land use permit.

All ADUs must meet the following criteria found in Chapter 20.21 of the Edmonds Community Development Code (ECDC) in order to be approved.

In 2021, the Citizens’ Housing Commission stated the following policy recommendation for updating the ADU code to include DADUs:

“Allow either one attached or detached accessory unit on a property in the SFR area, with clear and definitive development requirements such as size, ownership, and parking, under the standard permitting process and not require a conditional use permit.”

According to the 2021 American Community Survey, 21.5% of Edmonds’ residents are over 65 years of age and one of the major concerns among our senior residents is whether DADUs are allowed for ‘aging in place.'

What is HB 1337 ?

HB 1337 is a statewide housing bill focused on accessory dwelling units (ADUs), aiming to broaden housing choices by easing barriers to the construction and use of accessory dwelling units.

The bill specifies that the city allows at least two ADUs in any zone where single-family homes are permitted as a secondary outright permitted use. The bill also addresses topics such as ADU size standards, owner occupancy, and condominium sales.

Homeowners will have more flexibility to build new ADUs or convert existing structures in order to provide additional income opportunities, increase the availability of affordable housing, and support aging in place.
