Since an inspector is going to look at all the major systems of your home, make sure there is easy access throughout the house, especially to a furnace, water heater, or any other appliance that the inspector will look at. Before the inspector arrives, make sure access is not hidden or thwarted by large items – for example, if your crawlspace is accessible through the closet of a bedroom, make sure there is nothing in the room or the closet that will prevent the inspector from getting to it. Also, provide details on where the inspector can find attic and crawlspace access, and ensure those access points are ready for the inspector. Sometimes if an inspector cannot get access to something, s/he will need to reschedule and there can be additional charges for having to return.
