Plans have been submitted for a 12x12 storage room attached to the back side of an existing garage with no entry into the garage from the storage side. The plans call for the storage room to have a pier placed at all corners and every 6ft. (Total of 9 piers) The piers closest to the garage back wall will be pinned into the garage foundation with rebar. Rebar extending from the piers will be connected to a 6" slab with rebar above the top of the piers. All of this appears to be a way to get around pouring a footing. Has anyone seen this done before, would it be allowed by code?
