I have a prospective tenant who wishes to cultivate medical marijuana in my business property in Los Angeles, CA. He has a legal license and claims to grow "for a medical marijuana dispensary." Would there be any problems if I lease my property out to him? I don't want to get in trouble with the law. Also, are there any specific steps I should take to prevent future legal problems? So far I plan to consult an attorney to revise my lease contract to suit this special situation. Thanks for the help.
