Given the owner does NOT record a Notice of Completion or Cessation. When the deadline to file a California Mechanics Lien is within 90 days after completion of the work of improvement, I don’t understand the definition of “completion”. It may not be well defined, and possibly there are some loose interpretations. If my work is substantially complete, but not all is finished, and I return at the direction of the general contractor to complete a significant size of the work remaining, does the 90-day deadline commence from that day? If I return to repair damaged caused by others, after my work was completed, does the 90-day deadline recommence from that day? If I do a minor repair, does the 90-day deadline recommence from that day? If I come back several weeks after completing my work to perform a warranty repair, does the 90-day deadline recommence from that day? I just don’t know what constitutes completion and the 90-day cutoff. Thank you for your help.
