Does this qualify for Breach of Lease?

[Sofiya Cherni]

Montgomery County, MD.

Would this constitute as BOL?

18+ son moved in permanently but is not on the lease?  Am I required to give the opportunity to add him to the lease? I prefer to evict instead of adding.

Also, tenant admitted after the fact that her mother stayed with them for a month. Per lease if anyone not on the lease is staying over 2 weeks I must be notified, they must fill out application, pass criteria and be added to the lease. 

Are these two instances sufficient to evict based on BOL?

The rent, in 2+ yrs, has never been paid on time. It is paid late each month by the 10th (usually on 7th 8th or 9th). I can’t collect late fee till after 10th.

In summary, they could care less about my rules, I’ve had enough of them and would like to evict.
