Precisely.
And the entire universe, contrary to popular belief, does not revolve around California.
Most states have what are called "owners rights". These rights include access to the property they own at any reasonable time.
No, I can't come using my key and entering my house you're leasing at 3 in the morning to see "what's up". But it is perfectly within my rights to pop by at noon one day to check out my property, make sure it's not being abused, service the things I need to such as change the air filters and such, and see to it that the lawn and surrounding areas are being properly cared for.
It is, after all, my property.
And, even under California law there are exceptions as mentioned before.
In the end though, he's changed his story from "I OWN my house!" to going and doing research to try to back up a failed argument. In the end, it's still my property. If you want to relocated your grown every time I give you notice that I'm coming by to inspect my property, are you really going to do that?
No. Of course not. Because you're going to have to relocate that grow every two weeks. That's going to cause you far more grief than it's worth.
Growing being legal in California has nothing to do with an owners rights and what is in the lease agreement. That is why if you are in doubt at all, then you shouldn't do it. That is all I stated from the very beginning until Sir Horses Ass showed up spouting his mouth off about "I OWN my house".
