(3) Divisions made by testamentary provisions, or the laws of descent;

(4) Divisions of land into lots or tracts classified for industrial or commercial use when the city, town, or county has approved a binding site plan for the use of the land in accordance with local regulations;

(6) A division made for the purpose of alteration by adjusting boundary lines, between platted or unplatted lots or both, which does not create any additional lot, tract, parcel, site, or division nor create any lot, tract, parcel, site, or division which contains insufficient area and dimension to meet minimum requirements for width and area for a building site;

(7) Divisions of land into lots or tracts if: (a) Such division is the result of subjecting a portion of a parcel or tract of land to either *chapter 64.32 or 64.34 RCW subsequent to the recording of a binding site plan for all such land; (b) the improvements constructed or to be constructed thereon are required by the provisions of the binding site plan to be included in one or more condominiums or owned by an association or other legal entity in which the owners of units therein or their owners' associations have a membership or other legal or beneficial interest; (c) a city, town, or county has approved the binding site plan for all such land; (d) such approved binding site plan is recorded in the county or counties in which such land is located; and (e) the binding site plan contains thereon the following statement: "All development and use of the land described herein shall be in accordance with this binding site plan, as it may be amended with the approval of the city, town, or county having jurisdiction over the development of such land, and in accordance with such other governmental permits, approvals, regulations, requirements, and restrictions that may be imposed upon such land and the development and use thereof. Upon completion, the improvements on the land shall be included in one or more condominiums or owned by an association or other legal entity in which the owners of units therein or their owners' associations have a membership or other legal or beneficial interest.

Furthermore, this subsection only applies to electric utility facilities that will be placed into service to meet the electrical needs of a utility's existing and new customers. New customers are defined as electric service locations not already in existence as of the date that electric utility facilities subject to the provisions of this subsection are planned and constructed; and

*Reviser's note: Chapters 64.32 and 64.34 RCW were repealed by 2024 c 321 ss 501 and 502, effective January 1, 2028.

Findings—Intent—2024 c 190: "The legislature finds that fire protection is a critical component in maximizing fire preparedness and response in rural and suburban areas of the state that are living with increasing fire danger. Even though this year was not characterized by excessive forest fires, the fires that did happen were devastating. The legislature finds that areas with existing communities that oftentimes include rural school districts and fire districts need the ability to increase fire preparedness and response times. The experiences of the last few years have shown that rapid response is highly effective in reducing the destruction of wildfires. The legislature intends to be a partner with these communities in maximizing fire protection by enabling existing fire districts to expand their services." [ 2024 c 190 s 1.]

Finding—2019 c 352: "Tiny houses have become a trend across the nation to address the shortage of affordable housing. As tiny houses become more acceptable, the legislature finds that it is important to create space in the code for the regulation of tiny house siting. Individual cities and counties may allow tiny houses with wheels to be collected together as tiny house villages using the binding site plan method articulated in chapter 58.17 RCW.

The legislature recognizes that the International Code Council in 2018 has issued tiny house building code standards in Appendix Q of the International Residential Code, which can provide a basis for the standards requested within this act." [ 2019 c 352 s 1.]
