Anyone who provides labor, materials or supplies valued at $500 or more to the repair or improvement of real property can file a mechanics lien, provided that they are licensed (if a license is required by law for the work). Any claimant who has not contracted directly with the owner must provide a Notice of Right to Lien within 21 days after the first provision of labor or materials to the project.
If you haven't been paid for your services, you must first serve the homeowner with a Notice of Intent to File Lien at least 15 days before you record your mechanics lien.
