Property Restriction Hierarchy

When purchasing or developing property in Bonneville County, it's important to understand the full hierarchy of restrictions that may apply:

  1. County Zoning: The base regulations that apply to all properties in unincorporated areas of Bonneville County

  2. City Zoning: Properties within city limits follow city zoning instead of county zoning. In Bonneville County, these cities include:

    • Idaho Falls - Has its own comprehensive zoning ordinance with residential, commercial, and industrial districts

    • Ammon - Maintains separate zoning regulations with unique requirements

  3. CC&Rs: Many subdivisions have Covenants, Conditions & Restrictions that add further limitations beyond zoning

  4. HOA Rules: Properties in HOA-governed communities must also follow homeowners association rules, which can be even more restrictive

This hierarchy is important to understand because even if county zoning allows certain uses, city zoning, CC&Rs, or HOA rules may prohibit them. We'll be creating detailed guides for each city with separate zoning to help you navigate their specific requirements.
