Sunroom Addition Framing

[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,

Completely inadequate. Better carefully shore all that before it all comes down, or just demolish it and start over.

hokie66,
thank you for response, I share your opinion. Do you have a reference to IRC or some other code stating how it should have been built? Through-bolted?
thanks,

IRC R703.1.3 does not allow masonry to support any load other than the masonry dead load above it. Further, veneers are not allowed to support structural loading other than lateral wind load transfer as noted in the primary code.

Also note that there is usually an administrative provision that requires compliance with the primary code (IBC) in the event that a subcode is silent on the issue. In that case see Chap 14 of the IBC...it does not allow.
