here the township workers report ALL folks they see to the code enforement officer...no permit to work? Expect a visit and the consequences of it.
Several years ago, heck, it may have been 10-15 years ago, several of our local governments started requiring contractors to be licensed with them. So there's several cities, towns, the county, state, etc... that you may have to get licenses/permits with before you can do work inside their boundaries.
You know why that is, right?
