Well once you have your permits and the house is free of lead paint. absestos, all that stuff you have to disconnect the water, sewer, eletrical, and gas is applicable. The oil tank if it has an oil tank has to come out before any demo. Then start taking the house down. Like said in a previous answer start with the top and push in so you have little clean up work by hand. I used to leave the chimney standing and took it down after i loaded the demo because its a lot more money to mix the brick in with the demo. Then load out the chimney bring it to a dump. Next is the foundation, if its a fieldstone foundation you can probably bring it to a concrete company who will use it to make concrete. If its block bring it to a crushing company. Next comes the site work, but we'll wait to give you a step by step process on that.
P.S. try and crunch the demo up as you go so youll have less air pockets and be able to fit more i the demo trailer.
