Definition of
Adhesion Contract from uslegal.com
First and foremost, it should be understood that any contract is typically biased to the one who wrote it. Therefore, in my opinion, all contracts are adhesion contracts. That is "a contract balanced in favor of one party over the other that one can assume it was not entered into on equal bargaining grounds."
As with all contracts, especially home purchases, one side can always refuse to enter into the contract. Adhesion contracts, based on the definition provided, "Adhesion contracts are usually formed when one person is in a superior bargaining position and pressures the other party into a contract with
unfair or
oppressive terms" it's, in my opinion, difficult to make a case that the deed restrictions are unfair or oppressive when the Association is under membership control.
Granted, it could be argued that when an Association is under Declarant control, that the contract could be unfair (based on votes per lot). However, nobody is forcing you to purchase the home/property and there are usually other homes available nearby.
So, in my laymans opinion, in regards to membership controlled Associations - no.
In regards to Declarant controlled Associations - perhaps (but there are other properties available).
