.5C,DF,_ 7o""c� KITTITAS COUNTY COMMUNITY DEVELOPMENT SERVICES ` 411 N.Ruby St.,Suite 2,Ellensburg,WA 98926 CDS @CO.KITTITAS.WA.US Office(509)962-7506 Krrrrrnsco[mTr "Building Partnerships—Building Communities" Item 25-03 HB 1337 Updates On July 23, 2023, HB 1337 became effective in Washington State. HB 1337 provides new guidance and requirements associated with the development of Accessory Dwelling Units (ADU's).The Bill is intended to encourage ADU development through lowering development standards and increasing allowances in Cities, Urban Growth Areas, and LAMIRD's.The Bill requires local jurisdictions to adopt complying regulations within 6 months of their next Periodic Comprehensive Plan Update. Item 25-03 involves updates to the following Kittitas County code sections. 17.08—Definitions, 17.15.050—Allowed uses in Resource lands, 17.15.060-Allowed uses in rural non-LAMIRD lands, 17.15.070-Allowed uses in rural LAMIRD lands, 17.15.080-Allowed uses in Urban lands, and 17.36.015 Applicability. Many of the provisions in HB 1337 involve development standards more frequently associated with city jurisdictions. Limitations on design standards, impact fees, parking requirements, size, and setbacks from alleyways make up much of the bill. Current ADU regulations in Kittitas County are largely compliant with HB 1337, but some changes are necessary to ensure consistency. The proposed updates will amend all four allowed use tables and the footnotes associated with each use table.The updates will remove the"Accessory Living Quarters" definition and use within all applicable code sections.The Accessory Living Quarters use has not been completely removed, but relocated under the "Accessory Dwelling Unit" definition,to ensure consistency with HB 1337,which makes no distinction between the two. Additionally,the update will change the standards for ADU development, as expressed in the footnote section of each use table. It will increase permissions for up to 2 ADU's within UGA and LAM IRD designations when general development standards can be met. It will maintain an off-street parking requirement of one spot per ADU and eliminate minimum lot size requirements for ADU development within the Urban Growth Areas and LAMIRDS. While preparing this update, staff discovered an errant footnote (#51)within the Rural Non- LAMIRD use table that applied to all lots within the Ag-5, Rural-5,Ag-20, and Forest and Range zones.The footnote states, "When enhanced agriculture sales are provided."While this change is not associated with HB 1337, the footnote did not make any sense, so we are suggesting removal of this as part of this update. 106
