Is there a law against not putting a air conditioning system draining tube outside the house?

My home has a condensation/draining tube that drains inside the wall. Is there a law against that and what is the law?Is there a law against not putting a air conditioning system draining tube outside the house?
Is the existing drain going through a wall to the outside or not? Personally, I don't care for the idea of draining to the outside. There is too much possibility of insects and such getting in the drain and clogging it up. If a humidifier is going to share the same drain you DEFINITELY don't want it going outside, it will freeze up in the winter. Draining it inside the dwelling with as short of a run as possible is preferred. The best way is to use a condensate removal pump that has a safety switch float switch on it. This way if your drain tubing clogs up or your pump fails, the float switch will shut down the system to prevent a flood.Is there a law against not putting a air conditioning system draining tube outside the house?
each state has a plumbing, hvac, electrical etc code (law) to go by. Your ac must have a drain, even the window units have them. Some drain by gravity, some have condensate pumps, some go into plumbing pipes (indirect connection)
