I hope you are able to sail right through the approval process. It took me 2 months to get a building permit for my shop here in this county. It was not the huricanne design requirements so much as it was in dealing with the permit office it self. I just kept telling myself "Its all about Taxes ..."
Good Luck! Oh ... BTW .. It ended up with 14 Ga. metal studs and 21,000 metal screws! Not much wood in the structure other than the roof!
