Legal issues with basement rental

[Michael Mcdonough]

I have renters who moved in 4 months ago. (They live in my basement apartment) they have broken many things in my contract and have now said they plan on leaving in a month. Our contract is a year long. They said if I show there place for future renters they will get authorities involved. I want to evict them and sue them for the many things they have broken in my contract but I have one concern. I’m not sure my place is for sure legally able to be rented out to 2 adults and 5kids! I need help on what to do and who I may need to talk to.
