Notify or not to notify (Tenants are not supposed to be there!!!)

[Dave S.]

So Im in a particular situation, where my tenants were supposed to of moved out a while ago (Jan time frame with not even the defined 30 day notice but a 60 day notice!!), and enough was enough and come END of Feb we posted a notice to quit on the door for them to be out end of March. The tenants paid their rent, werent behind on payments, just needed them out so we can fix up a few things and sell the property). I have contractors aligned to start work and getting the property ready for sale. Am I still obligated to notify the tenants (even though they are supposed to be out) when the contractors are going to be there. Some of the work can be done solely from the outside (i.e. the roof). I dont want the tenants to think Im letting off the gas to get them out by reaching out past when they are supposed to be out! Please advise
