Findings—Intent—2020 c 217: "(1) The legislature makes the following findings:
(a) Washington state is experiencing a housing affordability crisis. Many communities across the state are in need of more housing for renters, across the income spectrum. Accessory dwelling units are frequently rented at below market rate, providing additional affordable housing options for renters.
(b) Accessory dwelling units are often occupied by tenants who pay no rent at all; among these tenants are grandparents, adult children, family members with disabilities, friends going through life transitions, and community members in need. Accessory dwelling units meet the needs of these people who might otherwise require scarce subsidized housing space and resources.
(c) Accessory dwelling units can meet the needs of Washington's growing senior population, making it possible for this population to age in their communities by offering senior-friendly housing, which prioritizes physical accessibility, in walkable communities near amenities essential to successful aging in place, including transit and grocery stores, without requiring costly renovations of existing housing stock.
(d) Homeowners who add an accessory dwelling unit may benefit from added income and an increased sense of security.
(e) Siting accessory dwelling units near transit hubs and near public amenities can help to reduce greenhouse gas emissions by increasing walkability, shortening household commutes, and limiting sprawl.
(2) The legislature intends to promote and encourage the creation of accessory dwelling units as a means to address the need for additional affordable housing options." [ 2020 c 217 § 1
