IABO Code Talk

We are interested in hearing from Jurisdictions whose Building permit fees include the subcontractors(no seperate fees)and any discussion from anyone on this methodology

Do any jurisdictions reduce the building permit fee for modular/manufactured units that have the "HUD stamp" where no rough-in or framing inspections would be needed?

I am having trouble understanding 09 IBC Tab 508.4 which is nearly the same as 06 Tab 503.3.3, at least for my question. Per both tables, no occupancy separation is required between either an F-2 and an S-2 or an F-1 and an S-1 occupancy, however a 1 or 2 hour separation is required between an F-2 and an S-1 occupancy or between an F-1 and an S-2 occupancy.

Could someone please explain the reasoning behind this? It seems counterintuitive to me that a more stringent requirement would be required in the latter case.

Thanks for any enlightenment.
