I'm not sure if this is what you're wondering, but Vault 21 and Lucky 38 are seperate buildings on the Strip. Lucky 38 is not a Vault or even a casino, but a massive signal array and storage facility for Mr. House's plans. He bought Vault 21 much later, but yes, he owns it as well. Just wander the Strip and you can't miss the sign..
