Eagle Zoning & Land Use Guide
Key Zoning Facts
Eagle Zoning Overview
Eagle is an affluent suburban city in Ada County, located northwest of Boise along the Boise River. Known for its equestrian properties, large-lot residential areas, and the charming Old Town Eagle district, the city has grown significantly while maintaining a semi-rural character in many neighborhoods. Planning and Zoning administers a code that emphasizes low-density residential development, open space preservation, and protection of the Boise River corridor.
Eagle's growth has been shaped by the development of master-planned communities alongside established ranch and equestrian properties. The Boise River provides both recreational amenity and environmental constraint, with floodplain regulations affecting development along the river corridor. Old Town Eagle has been revitalized as a mixed-use village center with restaurants, boutiques, and community gathering spaces.
Key Zoning Districts
Eagle includes R-E (Residential Estate, 1-acre lots), R-1 (Single-Family), R-2 (Two-Family), MU (Mixed Use in Old Town), and C-2 (General Commercial) districts. Planned unit developments are common in newer subdivisions, allowing modified lot configurations within overall density requirements.
ADU Regulations
Eagle permits ADUs on qualifying residential lots with owner-occupancy and size restrictions. The larger lot sizes common in Eagle provide more physical space for accessory units. However, HOA restrictions in many subdivisions may limit ADU construction even where zoning allows it.
Development Process
Permits are processed through Planning and Zoning. The commission reviews development proposals with particular attention to density, open space, and Boise River corridor impacts. The city's comprehensive plan emphasizes maintaining Eagle's semi-rural character while accommodating growth pressure from the broader Boise metropolitan area.
