In the past decade, the Nashville area has had a housing boom, probably rivaled only by Las Vegas. I don't know if it's the fact that Nashville has become a sanctuary city for illegals and the State turns a blind eye to their hiring, or the houses are just going up too darn fast and builders don't care about quality or a combination of those factors, but I've run across some ridiculous gaffs in half million dollar homes around here.
A friend wanted to separate a second story (third, if you count the dug-out garage/basement at ground level) master suite into two bedrooms (as per the original home plans-- first owner left out the wall to make one huge suite). No big deal, I go in and build a simple 14-or-so foot stud wall and lift into place.
My helper and I lift the wall up and discover a gap you could fit a 2x4 in sideways at the top of the wall, where it t-bones the exterior load-bearing wall. That's right, the wall is leaning out at the top,
3-1/2 inches. You don't even need a 4' level to see something like that. I'm wondering how no one caught this.
We go outside to look at the wall from the exterior... it's brick. I look straight up the wall, from the garage door opening, and can see each row of bricks is sitting out further than the next, by at least 1/8 inch. The wall looks like a little staircase with tiny steps going in reverse, up the entire wall.
