Is it recommended or necessary to open a business when you start renting your home on Airbnb?

Hi, we're located in California and just starting to rent our home on Airbnb. We are not sure whether or not we need (or it would be a good idea) to open a business. We are going to work with a property management company which will offer full service. However, we want to be able to deduct all the expenses that come with running an Airbnb, from the startup fees to the ongoing utilities and maintenance costs, including depreciation. Would it be possible to do this if we file taxes as private individuals or we would need to open a business to maximize our deductions? I realize this is a very naive question but this is the first time we're getting into this and would really appreciate some perspectives here.
