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 detached garage construction actually costs in Nashville comes down to home size, materials, and scope.
Where this comes from
Every figure is pulled from Nashville's public building-permit records and classified by the work described. Nothing is estimated or AI-generated. How the data works. The moment a Nashville homeowner adds a real receipt, this page upgrades to show what neighbors actually paid next to these permit values.
