Tenant doesnt' abide by the lease agreement

[Ali BenAyed]

I've been wanting to break the lease with this tenant. The next door neighbor called me to let me know that there are different people that live in the house I'm renting out, every 6 months, there are 2 dogs and he can smell smoking when the lease agreemnet has one person on it, allows for 1 dog only and prohibits smoking. I called couple lawyers, and they said Montgomery County doesn't allow eviction based on beach of contract, evictions are only possible when the tenant doesn't pay. Any suggestions how handle this situation?
