We are all tossing out ideas, most of which will work for a given situation. But we do not have the needed info to say yes this will work and this wont.
Does he need a permit to build and if so which ones.
Some electric inspectors are required to see the plumbing sewer finals before signing off.
What is his surroundings, lay of the land.
Distance from existing home and septic.
Does he have the equipment and skill set to do what needs to be done.
I do enjoy the sharing of ideas and Lord knows I learn heavily from all of you but we are guessing at this point.
Thanks for all of the replies, they are all very helpful!
I am a mechanical engineer, with the equipment/knowledge/friends to do about anything I could think of. I've rebuilt my house and once I finish the basement, the new building is next on the list. I will need a building permit which means I give the township $25 and tell them the size of the barn, case closed
Luckily we still do it the old fashioned way. The area is clear around the build site with the ground eventually sloping down towards my pond and creek.
Lots of people around here have porta pots at their buildings but I want something nicer for the family. If it was just a shop, that'd be fine.
Keep the ideas coming, I just want to have a rough idea on what I could do after the building is up. I have a well but just recently switched to rural water (it was just run out to the house). I will run a water line out to the building very easily using a trencher.
