good tenants, bad guest

[Linh H.]

My tenants, a married couple with their teenage son, is renting my 2 bed, 2 bath condo for almost a year now. Rent is always paid on time and I have no issues with them. They did tell me in advance that their daughter will sleep over occasionally and she is not on the lease. A few days ago, the HOA manager notified me that a girl was arrested on the Premises for drug use. The daughter was passed out on the stairs and the neighbor called the police and told the police that she belongs to my unit. My tenants lied to the police and said that they don't know the daughter during the investigation. And they told me the same story as well when I confronted them. The HOA manager said that there have been complaints from the neighbors regarding the daughter's visits. She would get drunk, makes a lot of noises, smokes indoor and claimed that she lives in the building. After several phone conversations, the parent finally confessed about lying to the police and was hoping that I can ban the daughter from visiting.

Can I evict my tenants because of the daughter? The lease may be terminated in case of any nuisance, disturbance, offensive conduct, illegal drug use, and obstruction of justice for lying to the police officer. I also have to attend a board meeting where I might get a fine or insist that I evict my tenant because the community has a drug free policy.

I plan to give them a Notice to Quit - 30 days to move out. I'll refund their security deposit, pro-rated their unused days - do whatever it takes to get them out and move on. It's driving me crazy.  Am I crazy?
