What the file shows
Solar Panels is the work Corona files most: 586 of these 1,829 permits, 32% of the file. The dearest median here is ADU / Guest House at $166,105; the cheapest is Water Heater at $2,300.
The figure to read is not the median but the range next to it. Garage is the least predictable work in this jurisdiction: half of those jobs land between $23,750 and $80,059, a 3.4× 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.
