Holy cow ! And this is the United States ! Where has the pioneer spirit gone ?
Here we have building permits, bringing electricity or water to the property must be done by professionals (you can dig the trenches yourself to save a bit), installing a septic tank requires a permit and you must adopt such and such a system according to the nature of the soil.
But inside your house, you can use telephone wire for outlets, and do whatever you like. I did all the electricity and plumbing myself, including 2 toilets, a bath, 2 showers etc. There has never been any inspection.
I liked the description of crowded Europe, I'm absolutely fascinated by the gigantic open spaces you have in America.
I'm not sure our numbers and Europe will bring more regulations, Americans seem to be real champs in the matter. Of course our British friends will always resent the least appeatance of meddling in their affairs and maintain their originality.
