A permit's declared value is the job cost the owner or contractor stated when they pulled the permit. It tracks the real cost of the work but can run a bit under what was actually paid, since it often leaves out some labor and finish costs. Treat the range as a grounded starting point. What basement finishing actually costs in Missoula comes down to home size, materials, and scope.
Where this comes from
Every figure is pulled from Missoula's public building-permit records and classified by the work described. Nothing is estimated or AI-generated. How the data works.
