Lawyers will suit everyone from whom they can potentially win money, including the BCC. They wouldn't likely be found guilty in this case, but I would expect them to also be sued by the buyer.
The laws are interesting regarding disclosures, especially if someone buys this property then resells it for a quick flip. If the buyer #1 never asked, and was never told about the County's ruling to remove the floors, he or she may not be liable to buyer #2 who gets screwed. (I'm not an attorney. This is just my understanding on Disclosures of Material Value.) It is also my understanding that Sellers are not required to disclose information of material value at will. A Realtor is, however, required to do so, but many sellers would never tell their Realtor in the first place. (Surprise!). That is why a buyer should always include an addendum for Property Disclosure Statements in the contract. When I list a property, I always request a Property Disclosure Statement to be completed by the seller, so that I am made aware of things which may affect a buyer's purchase decision. I have it handy so that any interested buyers can read it for themselves in include it in their contract. In many cases, if you don't ask, you don't receive. The Courts expect that buyers will perform their own due diligence, and when they don't they aren't given as much consideration, and may lose their case.
Scooter, I bet it adds even more planning to add two additional stories to a house. It wasn't mentioned in the article, but the actual height of the top of the tallest home built by this "developer," exceeds 50ft. In essence, it is a five story home, as some of the parking level is enclosed. Only two habitable floors were permitted.
