Storage Hangars

I have a row of six storage hangars.  Currently, there is a 1-hour separation between each hangar and they are anywhere between 3400 - 4200 square feet.  The outside walls are 2-hour rated and the offices inside each hangar are 1-hour rated.  Is each individual hangar considered a separate fire area?  If so, would I calculate the allowable square footage for each hangar as a Group III since it is storage only and no service or fuel or would it be the cumulative under roof square footage of 23,814; which I believe would bump it up to Group II hangar?
