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 furnace installation actually costs in San Francisco comes down to home size, materials, and scope.
Where this comes from
Every figure is pulled from San Francisco's public building-permit records and classified by the work described. Nothing is estimated or AI-generated. How the data works.
