What it takes to build here — permits, zoning, and septic — scouted from Sanders County’s own official sources.

Whether a new home can legally get its own water here — the sub-state groundwater regime, from Montana’s water agency.
New water supply here generally requires a permit, an offset, or buying an existing right — a household well is not automatic.
Montana's exempt-well exception (85-2-306 MCA) was tightened after Upper Missouri Waterkeeper v. DNRC (2024), and from Jan 1, 2026 appropriators must file a Notice of Intent with DNRC before putting exempt groundwater to use.
Limit: 35 gpm or less AND ≤10 acre-ft/yr; a combined appropriation exceeding 10 acre-ft needs a permit regardless of flow rate

Montana DNRC — Basin Closures and Controlled Ground Water Areas ↗Prior-appropriation state (first in time, first in right).
