I completed a water damage wok for a home, the rebuild is still in progress by the homeowner with my assistance in writing the scope of work, going over the scope of work with the insurance company and the homeowner. Last week I was at the house verifying measurments for the homeowner and insurance company, I need to give them a pre-lien notice. I should of given the pre-lien notice What work must I perform at the house to qualify for "Permanent Changes" or which of the following will qualify me to give a pre-lien? Change outlet covers? Take more measurements? Or what else would qualify to pre-lien the house (I think the pre-lien must be filed within 10 days of last work?)
