Speaking as a renter in Colorado with a grow-friendly landlord...
The first thing would be to look for an actual landlord as opposed to an agency or property management firm...
unless they clearly state a pro-grow policy.
Second - Ask dispensary and grow shop employees if they know of any properties or good contacts
In my case, it was a friend of a friend so I already knew that he had grown before I broached the subject...
but I understand that isn't really as much of a possibility for you.
The key is...you don't want to blindly trust someone you don't know...they have a key to the place after all
They could just as easily tell you yes then jack your harvest.
If you don't want to tell the landlord, then you'll have to make sure it isn't specifically forbidden in the lease.
If it's not spelled out, they can't legally evict you for it since rental statutes are enforced at the state level and
are therefore subject to state law, not federal. But there will always be a way for a landlord to get rid of someone.
(And that's an educated guess, not facts in evidence based on experience)
Best bet is to cross the t's and dot the i's and find a trustworthy, cool landlord and be completely above boards.
The availability of which will depend on where you're moving...i.e. Boulder vs. a more conservative town.
Smaller is probably better too, as it relates to person to person rental relationships and general attitude.
My 2 cents.
