What is a mechanic’s lien in Arizona?

A mechanic’s lien is a legal claim that contractors, subcontractors, and material suppliers can record against a property when they aren’t paid for work or materials that improved it. In Arizona, parties who lack a direct contract with the owner generally must serve a preliminary 20-day notice to preserve lien rights, and the lien must be recorded and enforced within strict deadlines. A recorded lien clouds the property’s title until it’s resolved.

For suppliers and subs, the preliminary 20-day notice is the critical first step — miss it and lien rights can be lost even if the debt is real. Arizona also sets firm deadlines to record the lien after work is completed and to file suit to enforce it.

Note that lien rights are narrower on owner-occupied homes where the owner has fully paid a licensed general contractor — one more reason licensure and clear records matter to everyone in the payment chain.

Knowing who the contractor and property owner actually are is foundational to protecting lien rights. PlumbIntel ties each permit to the contractor’s license and the property’s owner of record, which is exactly the information a supplier needs to send notice to the right party.
