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 deck installation actually costs in Bethesda comes down to home size, materials, and scope.
