In my experience units requiring "no Board approval" are Sponsor units. When the Sponsor develops the coop rules, he/she exempts Sponsor units from the approval process so that they can be sold more quickly and easily. This exemption extends only to the first time the unit is sold.........by the Sponsor to Buyer #1. From that point on, every subsequent buyer must receive Board approval. The exemption extends only to the entrance requirements, not the House Rules, which everyone must adhere to. To be clear..........the only units requiring "no Board approval" are Sponsor units. This is just another way of expressing it.
