Wow, I would not allow that if I owned a mobile home park. That's YOUR time, blood, sweat, and money you have in that place. You need to talk to a Realtor that specializes in property management, as well as a lawyer, at the same time if possible.
You have every right to not allow that, it's your ass on the line!
Veggi is right, IT IS AGAINST FEDERAL LAW, and you are just begging for it if you allow and encourage that. It's your choice though, seems that the consequence and risk far out weigh any benefit.
If one of your tenants opens their hole and starts to say anything like, "it's legal blah blah I have a medical condition..."
Whatever, they are ignorant as hell and or don't give two shits about what could happen to you.
Unfortunately prop 215 and sb420 were created irresponsibly and are intentionally vague. Despite this, federal law trumps state law period. You can't use ignorance as a defense in court. Not to mention if you were aware of, condoned, ect... the illicit manufacturing of cannabis then like Veggi said you are up for losing everything, up to and including your life.
The fact that you own a mobile home park, and somehow don't know what to do troubles me, and I kind of don't think you own a mobile home park. But I don't mean to judge either, so if you do and you are sincere then I have offered up my personal advice to you, knowing that the posts to follow will likely be flaming, and ignorant.

I have to give praise to Veggi for being honest with you he is right, so am I. Good luck.
8182KSKUSH Reviewed by 8182KSKUSH on . Is it okay to grow outdoors in mobilehome park I own a mobilehome park in Yuba County. I have been told that several residents are growing medical marijuana in their spaces. I want to find out if it is legal for them to do this. What are the laws about growing outside. They have put fences around the plants, and have put up some piece of paper near the plants. What are the legal requirements, so that I can make sure they follow them? Thanks! parkowner Rating: 5
