I'm planning the deck I want to build, and I noticed this in my local city's deck code book:
"DECK FOOTINGS CLOSER THAN 5'-0" TO AN EXISTING EXTERIOR HOUSE WALL MUST BEAR AT THE SAME ELEVATION AS THE FOOTING OF THE EXISTING HOUSE FOUNDATION."
Given that it's all caps, it must be important, but I'm curious why, and if I can get around only having footers that are 30" deep and ~2' from the exterior wall. I'm using 6x6 posts, and attaching to the house via a ledger. The close footings are to frame around a bay window that's 9 feet wide. Anyone have any thoughts? Thanks.
