Does the owner need to be with contractor in a rented unit?

[Zoltan Fagyal]

I have tried to do some research on this but came up with nothing. I'd appreciate your help with this.

It's probably Massachusetts specific.

My unit is rented with a 1 year lease in Massachusetts. There is some paint work being done. It takes two days. I was there on the first day to meet with the painter and go through what needs to be done. Would the landlord need to be present while the painter is working? I think the answer is no, but I wanted to double check here. 

Thanks in advance!
