How do city land rights work in a place like King’s Landing? Does the Crown own all the land, lease it out to nobles and rich people, who then sub-let it and so forth? Just lots of squatting?

It could be anything – the Crown as direct land-lord, various forms of sub-infeudation, rent-farming, the list goes on and on…

But it’s unlikely to be squatting – even in the case of “clutter of ramshackle structures” on the wrong side of the Mud Gate, there were tenants who were damn pissed about having their stuff burnt by Tyrion and who wanted compensation.
