California tells me I didn't file documents for an LLC that isn't mine. What do I do?
Did it show just your address, or was your name on it as well?   You didn't share how long you've lived at the address either, so it makes me wonder whether a former tenant is the one who filed that paperwork.  It's also possible that someone used your address when making a filing.  Whether that was deliberate or accidental is hard to discern, as is their intent if it was intentional. It could be accidental -- someone picked "CA" for California when they meant to pick "CO" for Colorado or "CT" for Connecticut...These things do happen.  It can't make you feel any better about the situation though. You should be able to go online to the California Secretary of State's website (here) and look up everything filed by the LLC with the state.  That will show who the founders were and everything else that is a matter of public record on the LLC.  At the very least, you can obtain the registered agent's name and address for the LLC, which you can then use to contact them and ask why your address is listed as the LLC's business address. Once you have that info, you can then contact the Secretary of State and tell them it isn't you so they can do whatever is necessary to correct this. This doesn't sound like a difficult matter to clear up, but it's important to do your homework first and gather as much information as you can before you call the state.  Answering "I don't know" won't get you very far with them compared to having the best answers you can about where the mistake started. I hope this helps. Good luck!
