@Elaina8 I have the same problem. I am looking to buy a condo in Phoenix and the HOA requires 30 day minimum rental. I have looked at their CC&Rs and it does not state the rental term to be minimum 30 days. However it does state that transient tenants are not allowed. I have looked up the definition ok transient tenants and it seems like hotel guests are transient tenants.
I have heard about the AZ AirBnB law as well. It says any city/town/county should not be prohibited from vacation rental. But I am not sure how you can use it to overrule HOA rules. I think HOA CC&Rs (rules) are very old and existed way before the AZ AirBnB law.
HOWEVER - I saw a listing on AirBnB for a Condo, I am familiar with and their HOA says they require 30 day min rental. So I am not sure how that condo unit is listed on AirBnB for short term rental. Maybe HOA is just not aware. And the condo unti has been on AirBnB for almost 2 years now
Please let me know what you hear back from your HOA. Thanks and Good Luck !
