Ammon
The City Where Tomorrow Begins — Municipal Open-Access Fiber East of Idaho Falls
Why People Move Here
Ammon is the city directly east of Idaho Falls that grew from an 1888 LDS settlement into a city of ~19,113+ (crossing 20,000 in 2025–26) — one of Idaho's fastest-growing communities. Its signature differentiator is Ammon Fiber, the municipally owned open-access fiber-to-the-home network that has won national recognition (2016 NATOA Community Broadband Project of the Year, featured in Fast Company and New America Foundation reports) for its infrastructure-as-a-service model: the city owns the gigabit+ fiber; multiple private ISPs compete on top of it; subscribers switch providers through an online software-defined-networking portal. Bonneville Joint School District #93 (separate from Idaho Falls D91) runs Hillcrest High School in Ammon with ~1,207 students. Sandcreek Commons, a 300,000-square-foot retail power center anchored by Cabela's, Hobby Lobby, and Broulim's, will employ ~1,000 at buildout. Median sale prices sit around $430K (Redfin January 2026, up 5.3% YoY) with list prices climbing toward ~$490K by April 2026 — above Idaho Falls proper but below the Idaho state median of ~$509,700. Luxury foothills subdivisions like Comore Loma offer 1.5–7 acre lots with homes from $250K to $1M+. Contiguous with east-side Idaho Falls (~8 minutes to downtown), Ammon shares the Idaho Falls labor market including Idaho National Laboratory, EIRMC, and Melaleuca.

FAQ — Ammon
What makes Ammon different from Idaho Falls?
Ammon is a separate incorporated city of ~19,113+ directly east of and contiguous with Idaho Falls. Key structural differences: Ammon residents attend Bonneville Joint School District #93 (not Idaho Falls D91), receive electricity from Rocky Mountain Power (not the municipal Idaho Falls Power), and have access to Ammon Fiber — the city-owned open-access gigabit fiber network. The median household income (~$84,154 in 2023) runs notably above Idaho Falls (~$73,110), and housing is slightly more expensive. The two cities share commercial corridors along Hitt Rd, 17th St, and Sunnyside Rd.
How does the Ammon Fiber municipal broadband network work?
Ammon Fiber is a city-owned open-access fiber-to-the-home network offering gigabit-plus speeds. Unlike traditional ISPs, the City of Ammon owns the fiber infrastructure itself and leases access to multiple private ISPs, who compete to serve subscribers over one piece of infrastructure. Residents switch between providers through an online portal using software-defined networking. The network won the 2016 NATOA Community Broadband Project of the Year award and has been featured in Fast Company, New America Foundation research, and national community broadband podcasts as a model for municipal open-access done right. Affordable 'lifeline' tiers are available for households with financial hardship.
