I would guess that in this area that unlicensed contractors, handymen and side jobbers are getting the bulk of the remodeling work. It's really hard to tell because so much work is done without permits. I think that at least 50% of the basement finishes, bath and kitchen remodels are done without permits. Even when permits are issued it can be only for a portion of the work. Example is a contractor permits service change and the rest is done under the table.
Just like the electrical inspector a licensed contractor doesn't get a call on many of these under the table type jobs. There are many unlicensed contractors that stay busy. There are many advantages to getting work done under the table, no permits so they can do whatever they want, no records or taxes for the contractor, no work slow down waiting for inspections. The down side is that by cutting corners they take a risk of fire or injury. Many homeowners are willing to take a risk to save money.
The up side is that much of the work is done very poorly and we get lots of service calls over the years. People don't believe me when I say this but there is not that much that goes wrong with a properly installed electrical system. If it wasn't for cheap made parts and hacks we wouldn't get that much work at all.
