sunroom addition

[PSUengineer1]

I observed the underside of sunroom addition framing that is seperating from house by about 1-inch horizontal distance. The ledger board supporting the ceiling joists is a 2x6 nailed to brick veneer of house (i don't know nail spacing). The ledger board supporting rafters is not visible. The ledger board supporting ceiling joists is nailed to brick, is this standard practice for a house built in 1975? Is there a code reference for this construction? My feeling is that the construction is inadequate but I do want to analyze the evidence against loading from recent heavy snowfall. Please see attached PDF with a few photographs.
Thanks,

jimjxs263,
Nailing a wood ledger to brick veneer is not a standard practice, nor is it acceptable. Fastening a structural support (i.e. ledger to support roof/ceiling framing for sunroom) to brick veneer is generally frowned upon and in some jurisdictions not permitted under the building code.

A better way to support the ledger would be to attach through the brick veneer and attach to the wood framed structure, or provide a line of footings, columns, beam independently supporting the ledgers at the face of the existing building.
