A.R.S. 33-992.01: Arizona's Preliminary Twenty-Day Notice (Lien Rights)

Updated July 10, 2026
In Short

A.R.S. 33-992.01 is Arizona's preliminary twenty day notice law. It lets a contractor, subcontractor, or material supplier protect future mechanics' lien rights by serving a written notice, generally within twenty days of first furnishing labor or materials. For a homeowner, receiving one is normal. It is a required heads-up, not a lien, and not a bill.

A.R.S. 33-992.01 (Preliminary twenty day notice; definitions; content; election; waiver; service; single service; contract)

This is a government work (Arizona statute, administrative rule, or city ordinance) in the public domain. Always confirm the current official text at the source before relying on it.

A preliminary twenty day notice is a routine document in Arizona construction. Contractors, subcontractors, and material suppliers send it early in a job. It protects their right to file a mechanics' lien later if they do not get paid. A.R.S. 33-992.01 is the statute that sets the rules. If you are a homeowner, getting one in the mail can feel alarming. It is not a lien. It is a normal step, and this page explains why.

What this statute says

A.R.S. 33-992.01 defines the notice and sets its deadline. The statute describes it as "one or more written notices from a claimant that are given before the recording of a mechanic's lien." A claimant is anyone who supplies labor, services, or materials to your project. That can include a subcontractor or a supply house you never hired directly.

The key rule is timing. The claimant must serve the notice "not later than twenty days after the claimant has first furnished labor" or materials to the jobsite. Serving it on time protects lien rights for the whole job.

The notice must reach more than one person. The statute requires service on the owner, the original contractor, and the construction lender, if there is one. It must also reach the person the claimant contracted with. So a supplier who sold pipe to your plumber may send the notice to you, even though you never dealt with that supplier.

What the notice must contain

The statute lists the required content. The notice must include a general description of the labor or materials and an estimate of their price. It must give the claimant's name and address. It must name the person who ordered the work or materials. It must describe the jobsite. It must also carry a warning to the property owner about what a lien can mean.

The twenty-day window and late notices

The 20-day deadline is not a hard cutoff that ends all rights. A claimant who misses it can still serve the notice later. But a late notice covers less. The statute limits the lien to work "furnished within twenty days before the service of the notice and at any time thereafter." In plain terms, a late notice protects the recent and future work. It does not protect the earlier work. This is why claimants send the notice early.

What this means for you

Getting a preliminary twenty day notice does not mean you owe extra money. It does not mean a lien has been filed. It is a routine, legally required heads-up. Most notices arrive within the first few weeks of a project. Suppliers and subcontractors send them as standard practice on almost every job.

Still, do not ignore it. The notice tells you who is working on your project behind the scenes. Keep every notice you receive. When you pay your contractor, confirm that the subs and suppliers on the list got paid too. Ask for lien waivers as you pay. A lien waiver is a signed release that gives up lien rights for the amount paid. That is your best protection against paying twice. On a home you own and live in, A.R.S. 33-1002 can bar a lien from a sub or supplier you never signed a contract with.

If a dispute does come up, know your other options. You can file a complaint against a licensed contractor with the state. You may also reach the Residential Contractors' Recovery Fund if a licensed contractor causes you a loss.
