If I use my apartment to form and LLC will it be considered a biz

[Chris Wenchell]

Has anyone here formed an LLC out of state? I am looking to do deals in two states one in CA where I live and in another state where I have family. I spoke with Zoom and they say CA needs a physical address to form an LLC. Does anyone know if you use an apartment address will it then be considered your business? If so is there any other address in CA to use like a PO box? I know to be protective you would need some form of entity, but are deals done around the country without forming an entity?
