An Arizona mechanics lien is a legal tool that contractors, subcontractors, suppliers, and other construction professionals can use to secure payment for work performed or materials provided. In Arizona, specific laws regulate the filing of a mechanics lien, ensuring that claimants follow proper procedures to enforce their rights. If you are involved in a construction project in Arizona, understanding these requirements is crucial. Below, we explore the essential aspects of filing a mechanics lien in Arizona.
What Documents Are Required to File an Arizona Mechanics Lien?
To successfully file a mechanics lien Arizona, you need to prepare and submit the following documents:
- Preliminary 20-Day Notice: This document must be served on the property owner, general contractor, and lender within 20 days of beginning work or supplying materials. Missing this step can jeopardize your right to file a lien.
- Mechanics Lien Claim: This document must include specific details such as the property description, the amount claimed, a statement of work performed or materials supplied, and the claimant’s contact information.
- Proof of Service: You must serve a copy of the lien to the property owner and other interested parties and provide proof of this service.
How Long Do I Have to Enforce an Arizona Mechanics Lien?

After filing an Arizona mechanics lien, you must take legal action to enforce it within six months from the date of filing. If you fail to do so, the lien expires and becomes unenforceable. To enforce a lien, you must file a foreclosure lawsuit in the appropriate Arizona court.
What Types of Projects Qualify for a Mechanics Lien in Arizona?
Arizona mechanics lien can be filed for various construction projects, including:
- Residential construction, such as single-family homes and apartment complexes
- Commercial buildings, office spaces, and retail developments
- Public and private infrastructure projects
- Renovations, remodels, and significant repairs that improve the property’s value
However, Arizona mechanics liens cannot be filed against publicly owned properties. Instead, claimants may pursue payment through bond claims.
What Happens After I File a Mechanics Lien?
Once you file a mechanics lien in Arizona, several things can happen:
- Payment Negotiation: Often, property owners or general contractors may settle the debt to remove the lien.
- Property Sale Impact: The lien attaches to the property, making it difficult for the owner to sell or refinance without resolving the debt.
- Foreclosure Lawsuit: If payment is not received within six months, you must file a foreclosure lawsuit to enforce the lien or risk losing your claim.
What Is the Deadline to File a Mechanics Lien in Arizona?

Arizona lien law requires mechanics liens to be filed within 120 days of project completion. However, if the property owner records a Notice of Completion, the deadline is shortened to 60 days from the date the notice is recorded. Missing this deadline results in losing lien rights.
How Much Can I Claim in an Arizona Mechanics Lien?
You can claim the total unpaid amount for work performed or materials supplied. However, Arizona lien laws do not allow for punitive damages, attorney fees, or interest beyond what is stated in the contract. The lien amount should accurately reflect the unpaid balance to avoid legal challenges.
How Long Does a Mechanics Lien Last in Arizona?

A mechanics lien Arizona remains valid for six months from the date of filing. If not enforced through legal action within this period, the lien expires. In some cases, lienholders may request an extension, but this requires court approval and is not guaranteed.
Can I File a Lien If I Missed the Preliminary Notice Deadline?
No, missing the 20-Day Preliminary Notice Arizona deadline can disqualify you from filing a valid mechanics lien in Arizona. This requirement ensures that property owners are aware of potential claims early in the project. If you miss this step, you may need to pursue other legal remedies, such as breach of contract claims.
