The answer to this question falls under the "discretion of local law enforcement" and by that I mean that if you have to spend YEARS of time and your life savings to defending yourself in court, you've already lost. Ask Bruce Olson...

My guess is that you can have 2 notes for every patient THAT LIVES ON THE PREMISIS. If you're growing (for yourself) in your home, it's not a co op, even if you are also a provider for someone else.... Anything more than this seems like you're asking for trouble...

It would seem that a rented space, with more than one patient, but no one living there, would fit the very definition of a co op.

It would also seem that if a patient lived there, but had more than 30 plants, they would also be asking for trouble.
