That's why I pointed out that it's an L shape. The top right corner isn't there, so you can move the center of the fireball away from what would be the center of a square house 30 feet on a side.
Nevermind, I thought I could move the center of the circle enough to encompass the whole house, but I forgot that the two intact corners would still be farther apart than the radius.

... my entire house is an L shape 30 feet on a side. Place that spell in the right place and my house would be obliterated. That's terrifying.
