Cass County, North Dakota
Frontier is a city in Cass County, North Dakota. Frontier adopts its own zoning, so inside its limits Frontier’s rules apply, not the county’s. 12 rules below are quoted from official sources and independently re-checked, most recently on November 6, 2026. Rules for unincorporated land are on the Cass County page.

We looked and could not find an official answer yet. Silence is not permission; ask Frontier or Cass County directly.
Each answer was extracted from an official source and independently re-checked against that source by a second reviewer. That is an evidence check, not legal advice. Rules change; confirm with the authority before you buy or build.
Unanswered questions are usually a sign that Frontier publishes no rule on the point, not that none exists. Cass County’s page lists the county offices to call.
