In order to help alleviate these difficulties, and to enhance his/her ability to live independently and to fully use and enjoy the dwelling unit you own and/or administer, I am prescribing an emotional support animal that will assist [FIRST NAME] in coping with his/her disability.I am familiar with the voluminous professional literature concerning the therapeutic benefits of assistance animals for people with disabilities such as that experienced by [FIRST NAME].

As of Jan 1 14 selling marijuana will be legal here in CO where bandit signs will continue to be illegal.

Also if marijuana is legal I also will not allow it.That is just one example but there are many others which are property specific (who cuts the lawn) etc that you may need to think of.

Just looking for options.I had originally thought they hired a professional cleaner to remove the smell of marijuana. 

We are in a state that allows medical use and recreational use of marijuana, but we can still say no to smoking on our property.

With the HIPPA  Laws being in place how do you know your tenant is using medical marijuana or the marijuana they bought on the corner from a dealer and is it legal to ask in some states?

Or more recently, the legalization of marijuana - we can state our opinions and suggest to people what we feel may or may not be appropriate.

also: service animals we mentioned a few times by others  i actually would not mind a service animal in any of my apartments i feel there more well trained than people. the emotional support animals certification , i feel i going to abused more than medical marijuana cards in the future ( i live in Michigan its pretty bad here ) as more people are living in apartments and having pets instead of kids . 

@David Hunter It was Marijuana trafficking.

Include the CCR in your lease and have the tenant sign that if fines are incured due to the tenant behavior, the tenant will be in breach of the lease.99% of the time the tenant is doing one of a few things: parking in a red zone, having loud parties, bringing to many guests to the pool, unsightly belongings visible, unsupervised pets, not leashed, defacate in the common area, unsupervised children (that make noise and break stuff), speeding in the deiveway, bringing food, glass, beer or marijuana (legal in CO but not CA) into the pool area, indecent or illegal activities in the common area.I've seen it all.
