2. Apartments, condominiums, and similar developments with multiple dwelling units;

3. Subdivisions, except as provided in subsection (3) of this section; or

4. Commercial or business establishments or mixed-use establishments where the water is used primarily for commercial or business purposes.

(b) "In-home use" means the utilization of water within a residence or household, including all activities that require water, such as drinking, cooking, bathing, and cleaning within and around the household. It does not include irrigation of lawns, gardens, landscaping, pastures, or other open spaces.

(c) "Subdivision" means a tract of land divided into five (5) or more lots, parcels, or sites for the purpose of sale or building development, whether immediate or future; provided that this definition shall not include a bona fide division or partition of agricultural land for agricultural purposes.

(2) Except as provided in subsection (3) of this section, multiple water rights for domestic uses or domestic purposes shall not be established or exercised in a manner to satisfy a single combined water use or purpose that would not itself come within the definition of a domestic use or purpose under this section. The purpose of this limitation is to prohibit the diversion and use of water, under a combination of domestic purposes or domestic uses as defined in this section, to provide a supply of water for a use that does not meet the exemption of section 42-227 , Idaho Code, and is required to comply with the mandatory application and permit process for developing a right to the use of water pursuant to chapter 2, title 42 , Idaho Code.
