Insurance considers a DIY haunted house like any other house party. You might want to increase your liability limits for the duration of your haunted house. This way, if anyone gets injured while enjoying the spooks and spirits, you can have some peace of mind.
You may also want to ask your insurer about event liability insurance. This covers all sorts of grand events, from retirement parties to weddings and, of course, your haunted house.
Now, go get your spook on!”
