Commercial and Other Non-Residential Uses

While Ammon's zoning code focuses primarily on residential development, the city does accommodate commercial and other non-residential uses. These are typically regulated through specific provisions and are concentrated in designated areas, particularly along major corridors like Sunnyside Road and Hitt Road (Ammon Road).

Commercial development in Ammon is generally designed to serve the local community, with larger regional commercial uses concentrated in neighboring Idaho Falls. The city works to ensure that commercial development is compatible with its predominantly residential character.

Supplementary Regulations

Ammon's zoning code includes supplementary regulations that apply across various zones. These regulations address:

  • Special provisions for certain uses

  • Moving of buildings

  • Enforcement and administration

  • Board of adjustment provisions

  • Planning and zoning commission regulations

These supplementary regulations provide additional guidance for specific situations and help ensure consistent application of the zoning code throughout the city.

Zoning Procedures in Ammon

Understanding how zoning works in Ammon is just as important as knowing the zone designations. The city has established clear processes for:

Process

Typical Timeline

Zoning Verification

Confirming the current zoning of a property

1-2 days

Conditional Use Permit

Permission for uses allowed under certain conditions

30-45 days

Permission to deviate from specific zoning requirements

30-45 days

These procedures involve applications, fees, public hearings, and decisions by the Planning and Zoning Commission and/or City Council. Understanding these procedural requirements can save you time and frustration when planning a project in Ammon.

Relationship to Bonneville County Zoning

Ammon's zoning regulations apply only within the city limits. Properties in unincorporated areas of Bonneville County are subject to the county's zoning regulations instead. This distinction is important for several reasons:

  • Properties annexed into the city will transition from county to city zoning

  • City zoning is typically more detailed and restrictive than county zoning

  • Different procedures and authorities govern zoning decisions

  • Properties near the city boundary may be affected by both jurisdictions

Ammon has been growing rapidly, with ongoing annexation of previously unincorporated areas. If you're considering a property near the city limits, it's important to verify which jurisdiction's regulations apply and whether annexation might be required or beneficial.

Understanding CC&Rs and HOAs in Ammon

Beyond city zoning regulations, many properties in Ammon are subject to additional restrictions through Covenants, Conditions & Restrictions (CC&Rs) and Homeowners Associations (HOAs). This is particularly common in newer subdivisions, which make up a significant portion of Ammon's residential areas.

The Hierarchy of Property Restrictions

  1. City Zoning: The base regulations that apply to all properties within Ammon city limits

  2. CC&Rs: Private agreements that place additional restrictions on properties within specific developments

  3. HOA Rules: Specific regulations created and enforced by homeowners associations

Even if city zoning allows a particular use, CC&Rs or HOA rules may prohibit it. For example, a property zoned R-1 might legally allow for certain home-based businesses according to city regulations, but the subdivision's CC&Rs might prohibit any commercial activity entirely.
