Around this time every year after all my outside Halloween decorations are up, and I am able to start putting up my inside decorations people start asking why I do it. Am I charging admission to see my display? Doesn't this take a lot of time? Are you a Satanist? The answers are no, yes, and no respectively. I could leave my answers there, but I feel each deserves a further explanation.
In regards to the first question one of the unspoken rules among home haunters is to never charge admission. While there are some haunters out there that ask for donations to help to defray costs, most that ask for donations are doing so to give to some sort of children's charity. When you start charging admission you become a commercial enterprise. As such you are subject to all sorts of nasty things such as having to abide by fire codes and having to pay royalties for any music you use in your haunt. That's not to say that your haunt shouldn't be as safe as possible. If children are touring your attraction it should be as safe as possible since it is on your property and you probably don't want to have to make a home owner's insurance claim. Again, this is another reason most people don't go commercial since home owner's insurance doesn't cover business activities and you would need to purchase more expensive business insurance.
