I have a question regarding the notice of completion. The final inspection was done just a few days ago. My question is, how could I possibly provide a copy of the recorded NOC to all potential lien claimants if I don't know who they are? Would it be sufficient to express mail it to just my GC? If I don't send it to all the subcontractors, do I still get protected from them filing a lien after 30 days? My property is located in San Luis Obispo County, CA. I called the County Recorder office to ask about the Notice of Completion filing procedure and processing fee. At first, they didn't know what kind of form it was, had no idea about the form's purpose, then the calculated the charge of over $100.00, then they said that it takes 3-4 weeks to process. It makes me a little nervous, please advise, thank you so much!
