Dreams, Citizens did the exact same thing last year -- sent in their own hired inspectors to question the findings of inspections we had paid for previously, and which had been accepted by Citizens in the past. Very upsetting and frustrating!
I had to go through hoops to prove we had 100% Class A opening protection, after their inspector indicated our shutters weren't rated. B.S.!!!! They also downgraded our roof/deck attachment class because their inspector managed to find one remaining old staple to photograph in our attic space, despite the fact that the entire roof had been redone with
8d nails after Ivan.
We didn't find any of this out until a couple of months after the inspection -- their hired gun was entirely close-mouthed during the visit. I did chase him down before he left and gave him proof that we had a newer roof, because I knew he couldn't tell that simply by looking (and yet he'd never asked!), but otherwise trusted he'd have seen the same things our own hired inspector had found. Silly me!
So one fine day we got a letter from Citizens saying our annual premium was going up by a whopping $950 as a result of the inspection, and referring us to a website where we could view detailed results. We were incensed!
Turns out a lot of other people were, too, and I recall reading at the time that there was a class action lawsuit being instituted by some South FL people (can't recall the specific premise, but everyone had the same thought you did, Dreams, that the inspections were simply a ruse to get more premium money via a cold and calculated decision to give it a try and see how many people protested).
Long story short, we did protest, providing certification from Force 10 as to the shutter specs, and that alone knocked the premium increase down to zero (aside from the standard allowed annual rate increase). Fortunately, the roof/deck attachment issue became moot, as we had already exceeded the allowable credits via our shutters and other mitigation they didn't challenge (such as our newer roof, which they knew about no thanks to their inspector's efforts). I say "fortunately," because proving that one staple was not a true indicator of our overall attachment method was likely going to be a hassle, since they go by the lowest common denominator (cheapest method found).
I will say that the department Citizens had set up to handle people like me was pretty efficient, and the employees quite courteous -- but then (1) they were under threat of a lawsuit, and (2) it was easy for them to be magnanimous because (I'm betting) they were still earning lots more premium money from people who didn't challenge their findings.
Will be interested to hear what happens in your case, Dreams -- maybe things will go a lot smoother for you. I hope so. I would suggest trying to talk with the inspector when he/she in on site, see what's going to be reported to USAA before the report goes in, so you can perhaps prevent any mis-statements and/or omissions. But if you get any nasty premium surprises, don't hesitate to protest!
Hope this helps you and any others in the same boat. Sorry it's so long; I'm incurably verbose.
