You may have to redefine the legal term for landlord then, cause there are a lot of things that would count towards it on a legal level. For example renting out a portion of ones land for secondary use, an easy example is someone sticking a trailer on ones land and living there. Another two examples are closer to industrial but still count, renting land for livestock grazing and renting land for storage. Pretty sure they all count towards landlordship on a legal level.
