If you can buy an abandoned airport, you can open Las Vegas. If you mean that the other side is not wanted in the past, you have to make sure that CJ's brother is taken to prison, and CJ will open the way when he escapes. At other times, he will only be wanted by four stars.

Almost thirty or forty missions. When you open a garage in San Francisco and run errands for Woods, Delano will ask you to go to a cabin on the coast of Las Vegas. At first, you will be allowed to drive a cart, and then Las Vegas has been unlocked.
