What the file shows
Roof Replacement is the work Baton Rouge files most: 1,318 of these 2,570 permits, 51% of the file. The dearest median here is Home Addition at $103,000; the cheapest is Water Heater at $2,200.
The figure to read is not the median but the range next to it. Interior Remodel is the least predictable work in this jurisdiction: half of those jobs land between $25,265 and $200,000, a 7.9× spread inside one city and one kind of work. A median says where the middle sits. It does not say which half a particular job is in, and on work that varies this much the difference is the whole decision.
