That said, just got me thinking about actual historic homes... How much of the structure would be "original"?
On one that is truly historic, as in on list of registered historic places, the answer is whatever the local preservation society says must be. I've dealt with them before, they are way more tenacious than Rock Knocker. If they want, they will make it be rebuilt with all new materials to make it look exactly like the original structure. They can make you can find used materials that they consider appropriate. Here's the real rub, once a building is registered as historic the owner can't just tear it down and build something new. It all has to have the preservation society's blessing.
If I ever own a building that is about to be put on that registry, I would seriously consider tearing it down before they list it.
