Can a realtor show an occupied house without prior notice?

I rent a house in Arizona. The owners are selling the house and realtors have shown the house 4 or 5 times now without contacting me. I have had them remove the lockbox so the primary realtor is the only one with a key. But this last time she gave it to another realtor to show the house. She left a voice and email message about 30 minutes before the showing asking if it was ok. I was working and unable to receive these messages until 4 hours after the fact. I can see that this last time the attempt was made to contact me, but previous times the only way I knew the house was shown was misplaced sunglasses and business cards. Is this legal?
