Some jurisdictions will accept a letter stating species and grade from a certified lumber inspector along with a copy of the inspectors certificate. You would want to check with the building official in your jurisdiction to see if they would allow this. There are several lumber inspectors close to the area that I live, that will that will come to the site/ mill and grade the lumber. That may be an option but, check with your local building department first, to see what they are going to require
