Kuna Zoning & Land Use Guide
Key Zoning Facts
Kuna Zoning Overview
Kuna is a rapidly growing city in southwestern Ada County, located south of Meridian and Boise. Once a small agricultural community, Kuna has experienced explosive residential growth as affordable housing attracts families priced out of other Treasure Valley cities. The Planning and Zoning department administers a code that is evolving to manage this rapid transition from rural to suburban character while preserving some agricultural heritage.
The city's growth has been primarily in the form of new residential subdivisions on former agricultural land. The challenge for Kuna's planners is ensuring that commercial development, schools, roads, and infrastructure keep pace with housing construction. Indian Creek runs through the community, creating floodplain considerations for some development areas.
Key Zoning Districts
Kuna uses R-2 through R-20 residential zones, C-1 (Neighborhood Commercial), C-2 (General Commercial), and M-1 (Light Industrial) districts. The city also has agricultural transition zones for areas expected to urbanize. A town center district encourages mixed-use development in the historic core area.
ADU Regulations
Kuna allows ADUs on residential lots with a 700-square-foot maximum and owner-occupancy requirement. The newer subdivisions with smaller lots may present space constraints for ADU construction. Property owners should verify both zoning eligibility and HOA restrictions before planning an accessory unit.
Development Process
Permits are processed through Planning and Zoning. The city's comprehensive plan and area-specific plans guide growth decisions. Annexation is frequent as the city absorbs surrounding Ada County land. Infrastructure capacity analysis is an important component of development review due to the community's rapid growth rate.
