Roosevelt County (county seat: Wolf Point) covers 2,356 square miles with a population of 10,794 (2020). Official county website: www.rooseveltcountymt.gov/. This page summarizes the verified building-regulation posture of unincorporated Roosevelt County land; the full 10-dimension scorecard with every source receipt lives on its Freedom Map card.
On unincorporated NON-tribal fee land the county has no building department and is not on the DLI certified list, so single-family residences are permit-free under the state exemption (scored 9 on that basis). BUT >74% of the county is within the Fort Peck Reservation; on tribal trust land the county profile does not apply and building is governed by tribal/BIA jurisdiction (non-members generally cannot freely acquire/build). Status is strictly parcel-specific. Score 9 applies only to off-reservation / fee land.
The claim above is source-verified (official statute/county documents; URL, direct quote, and date on the full card). Method: how we verify.
No county's freedom erases state law: septic/wastewater permitting (health authority), well permits and water rights (state engineer/DNR), floodplain rules with federally connected financing, and — in some states — state-run electrical inspections. The full card details which of these bite in Roosevelt County and how hard.
The score describes unincorporated county land only. Inside Roosevelt County, incorporated municipalities set their own, usually stricter, rules — including: Wolf Point (city, county seat), Poplar (city), Culbertson / Bainville / Froid / Brockton (towns). Land inside town limits follows town code.
Building rules are the first question people ask about Roosevelt County — and the easiest one to answer. They're rarely the one that decides it. The full card grades all ten dimensions, every claim quoted from the county's own code.
