In Colorado, there are two different types of mechanic’s liens. One type provides for remedies to those who supply labor, materials, services and other lienable benefits for the improvement of property under contract with a property owner or the owner’s agent. We will call that a “Section 101” lien, 101 being the section of the Colorado mechanic’s lien statute that creates that lien remedy.
The other lien type arises when owners of property fail to post or serve notice upon others that their properties will not be liable for mechanic’s liens. Those notices must be given no later than five days after owners become aware that lienable work is being performed on their properties. That lien may be called a “Section 105” lien, again referring to the applicable section of the Colorado mechanic’s lien statute.
