Really need that picture.
Biggest concerns are water coming in under the walls and siding rotting out because it's to close to the ground.

You can close it in me and a friend did his. Made it into a bedroom fully functioned. Added a French door to backyard and ceiling fans and lots of other things.. Could use a picture of area for a better remodel suggestion.

Noobie question about carport conversion beam sag


For a ceiling, 1/2" deflection at the middle of a 22' span is not excessive. and is to be expected.
But that is presumably under dead weight alone. With any snow load (?) it will deflect further.

Snow load (as Tony said) is important, as is species/grade stamp of the beam. They are all rated to carry different loads per type/grade; eg. same size span solid wood beam will carry from maximum rating (per sag) of 900# to 2000# and numbers in between those figures---- need more info...

Did you have permits and inspections for the job? Almost no carports I've ever seen can be legally turned into living space since they lack proper footers. Not saying his didn't; just asking.
