You said in your post  "If the notice was delivered by mail then the notice period begins when the Tenant actually receives the notice."

However, the landlord may not need to give notice if they don't have a history of accepting late rent." 

Unfortunately, I’ve run into a major issue: I received a Stop Work Notice on my property in Covington, GA, because I didn’t have the proper permits for the renovations.I want to resolve this as quickly and smoothly as possible without jeopardizing the project.Can anyone offer advice or share their experience with:1.How to address the Stop Work Notice with the local authorities?

My question is, do I need to send a non-renewal notice as well? 

If the latter, simply give her the notice required (eg 30 or 60 days) that she needs to move. 

I notice that "Notice of an Independent Solar Energy Producer Contract" comes up a lot when filtering through Liens.

I ask them if they've already given notice.

I don't know what they are but unless there's something in the city that requires that kind of notice, it sounds excessive to me.

Send a Lease Violation Notice immediately - by mail with proof of delivery required (cheap date through post office) and or affix the notice in a envelope with his name on it on the door of the unit. 

If you had no knowledge and they broke the lease I'd issue a notice of non renewal, but give them the option to remove the cats.
