The City of Nampa proposes changes to its zoning code to comply with new Idaho state law taking effect July 1, 2026. The changes allow accessory dwelling units (ADUs) on single-family lots, replace the city's manufactured home rules with ADU standards, and create a new Starter Home Subdivision option with 1,500-square-foot lots on sites of at least four acres. This is a citywide rule change, not a specific building project.
