Known gaps
- Building permits: no city or county here publishes permits online. New construction appears only through state permits (DEQ, MDT) and new address points.
- Recorded documents: the recorder’s index is not online; documents are searched in person at the courthouse.
- Hearing agendas: commission and planning board agendas are not read for this county yet.
- Zoning: no zoning districts on file. Much of the county may be unzoned; check with the county planner.
- Sale prices: Montana does not disclose sale prices, so none appear on Data 4 MT.
