And this is why your masters have large mansions away from it all with armed guards.
This is normally done for commercial properties that are decaying, becoming an eyesore, and potentially a place for criminal behavior.
In Cali, because of Prop 13, it can be relatively inexpensive for an owner to keep a property in disuse without a tenant for years or even decades. I don't see how this helps anyone.
I definitely would be against anyone being allowed to break into an unused property, but I could see requiring an owner to utilize, rent out, or sell a property after a prolonged period of disuse, e.g. 5 years.
