First & foremost I agree with Ghost and Reno 100%
Here in NJ you would not be able to submit an electrical permit application without 'plans'! To do design/build...you still need plans with the permit app. Personally, I learned the hard way about providing a 'quote' on a no-plans yet' job. 98% of those people were shopping, or had 'friend'.
As to the classification of the building, Assembly guidelines are within the Building Codes, and the Building AHJ may make the determination during plan review.
