Well not quite like that. The building permit covers the racks and any modifications of the roof structure that might be required.fatboy said:CO has a similar law on the books,$500 max for review and permit, $1,000 for commercial. But, we would in my opinion be allowed, and would separate any structural work from the PV system, and permit it under our fee schedule. If not, what, I can build a new house, and put a system on the roof, and get a $500 permit? My factory for a $1,000?
