Liscence needed to manage short term rentals in California

[Wes Delabar]

My wife and I own and manage a couple vacation rentals in southern California. We have been approached by some neighbors of our properties and they are asking about us possibly managing them. My question is what is the license needed to be able to manage a short-term rental in California? do you need to have a broker's license like you do if you were to manage long-term tenants? Any advice or help would be greatly appreciated thank you.
