InSan Diego, you dedicate some of the units as affordable housing and you can get approval to add quite a few ADUs.  

After looking at your post, I realized it's probably necessary to have a dedicated real estate attorney handle this issue for me since it's serious and I might make a mistake big enough that probably will cost me too much money to fix.

AND Its my contract the customer signs .

Did the customer doors also. 

He claims to be Christian Based, but only rips poor customers like myself.

Many commercial leases have custom clauses. 

I'd lower the price slightly below your competition and get real reviews.Be customer focused.

So far, I've rated Evergreen and FCI lowest based on a number of reviews on different platforms that have consistent negative reviews mentioning certain specific issues that I find concerning (this is after accounting for the inevitable disgruntled customer/borrower who gets unjustifiably upset).Are you able to share any of your information?  

And a general contractor would NEVER sign a customers contract 

I suspect build cost in CA are closer to 400 a foot than 200 like many other areas and of course far higher for the custom homes.
