Setting up LLC for remodelling business in California

[Gav Chen]

Hello all,

I recently bought a residential property and now am in the process of looking into setting up a company structure to protect my interest and assets. I live in California state. I'm thinking to do some remodelling. However, I might want to do a several more remodel projects in the future. 

My questions are:

1) Should I set up two separate LLCs? One for holding the property and the other for dealing with contractors.  

2) If I have multiple projects in the future, is there any benefit if I set up a holding company to hold those LLC?

Thanks!
