Counties
All 56 Montana counties, and who actually regulates what.
Montana counties differ enormously — not only in what they publish, but in what they regulate at all. This registry is built county by county from primary county sources. Where a county does not publish something, we say so and name the office to call.

This county does not administer general zoning outside incorporated cities and towns. That is common in Montana and frequently misunderstood: no zoning does not mean no rules. Subdivision review, sanitation review, floodplain regulation, covenants and state building code can all still apply.
