For most things, if it passed code when it was built it is fine until/unless major renovations are done.
EG: the pitch of your roof might have been OK 45 years ago but today would be deemed too low (just an example). You could get the roof re-shingled without having to worry about code issues, but if you tore up the underlayment or did a large addition on the house that tied into that roof you might be required to re-do the now out of spec roof.
Commercial properties are different. Fire sprinklers are a good example, you might have a space that didn't require sprinklers 20 years ago, but if the code requirement is updated to say you now need sprinklers you'll have a timeline (1 year, etc.) where you HAVE to get the sprinklers installed in order to continue operation.
