Take a Video of him working Then call Lowe's and find where to send it
Call 211
There is a number online to report workers comp fraud and I believe there is even a reward if the person is caught. Just be 100% sure he is on workers comp before you go and make that claim because he is still your neighbor and you may have to deal with him for a long time!
Wow. Not sure what to do in this case. Sorry.
