Thanks.

So.... Presumably rule 550 is in chapter 5? And piecing together your summary with Don's comments about mobile homes, does that mean that chapter 5 (or at least 550-xx) applies specifically to mobile homes?

(Oh boy, this is hard work. [Linked Image] It's like when they completely changed the format of our "code" and rule B.24 suddenly became item 23-405-02, or whatever!)
