This old house is a joke. trust me, I did exclusivly 100+ year old homes. none of stuff they did would fly out west in a historic/ presevatin distric. not even close. Most people would faint if they saw what it took to even get a permit out here, let alone pass a review board.
The houses they work on in MA are much the same TAB. We have some of the same restrictive crap you go through as well but they're not going to show that in a half hour program! Doesn't make for good TV in the least. Most of the historical stuff needs more permits than the average contractors are willing to try and get approved! That, and the old crones who are on the "town historical society" and have to approve paints, windows, siding, roofing, etc....it's a phuqing nightmare here too...
Someone mentioned 700K This Old House projects. Some of these old homes in Lexington, Concord, Boston and the surrounding towns built during the 1700-1800's are multimillion dollar properties. A 700K upgrade is pretty average.
Hell, a 500K single level ranch inside the 495 loop around Boston is a burnt out shack! Who want's to see that on TOH?
