Tea? What’s tea? :margarit:
My bad, I forgot who I was talking with! LOL 
I have seen this, as well. The Builder is pulling your chain. I have insurance (E&O and GL, as well as bonding) and I just show up.
They have their “requirements” and I have mine. I work for the client, not them.
Most of the big builders, in this area, are writing into the contracts of sale a total prohabition of home inspections (even after the sale).
I point this out to my clients and go and do the inspection anyway (usually, after the sale, while it’s still in the “warranty” period.
But, there have been a couple of times that I have been met by a couple of large union members with 2 x 4s in their hands. One time, I came out and found my headlights and tailights broken.
When confronted by this, I refer the “secretary” to my lawyer. He explains the law and threatens an injunction on the development.
Works every time. 
Please, make sure that you retain a good real estate attorney who knows the law.
Many times, these putzes rely on the inspector’s ignorance of the law. If you have a good lawyer on your side, the just back off and fade away.
Hope this helps;
I’ve had builders throw the GL & EO with them as added insures on my policy; tell the buyer I had to be in hard hat and steel toed shoes to go on site; etc
I’m just as polite as can be - I tell my buyer I understand completely and we need a copy of the builders GL & EO policy to name buyer and me on site to protect us AND since its a company policy about hard hats and steel toed shoes - ALL their employees or subs on site better be dressed the same OR I take photos and start shooting them to EVERY media source around, etc.
Has worked 99.9% of the time so far - put it back in their court.
VERY GOOD!!! The house is supposed to be complete and ready for occupancy. WHY, of WHY would the builder want to convey a house where the owners whould have to wear hardhats just to live there?
I nomimate you for the "Nick Gromicko, Well Thought Out, Sneaky Bastard Award!!!
