Arizona lien laws are set out primarily in Title 33 of the Arizona Revised Statutes and cover several distinct types: mechanic’s liens for unpaid construction work, judgment liens from court awards, property tax liens, HOA assessment liens, and child support liens. Each type has its own filing rules, deadlines, and priority rank, and getting the details wrong on either side of a lien can be costly. Arizona’s homestead exemption also shields up to $400,000 in equity from most judgment liens, though tax and mechanic’s liens operate under different rules entirely.
What Makes a Lien Valid in Arizona
A lien starts with a legal basis and a recording requirement. The claimant must identify the property, state the amount owed, and describe why the debt exists. Most liens must be recorded with the county recorder’s office in the county where the property sits, and that recording is what puts later buyers and lenders on notice. An unrecorded lien is generally unenforceable against third parties.
Accuracy matters. Errors in the legal description or the amount claimed can expose the filing to legal challenge. So does timing: miss a statutory deadline and the lien can be void no matter how legitimate the underlying debt.
Mechanic’s Liens
A mechanic’s lien protects contractors, subcontractors, suppliers, and laborers who improve real property and don’t get paid. Under A.R.S. 33-981, anyone who provides labor, professional services, or materials for construction, alteration, or repair of a building or improvement has a potential lien on that property.1Arizona Legislature. Arizona Code 33-981 – Lien for Labor; Professional Services or Materials Used in Construction, Alteration or Repair of Structures The owner is treated as having authorized the work through the general contractor, so a subcontractor can lien the property without any direct contract with the owner.
The Preliminary 20-Day Notice
Nearly every claimant must serve a preliminary 20-day notice on the property owner, the general contractor, and any construction lender before recording. The notice warns everyone in the chain that the claimant has furnished labor or materials and may file a lien if unpaid. Without it, the lien is invalid.2Arizona Legislature. Arizona Code 33-992.01 – Preliminary Twenty Day Notice Workers performing actual labor for wages are exempt from this requirement.
Recording and Foreclosure Deadlines
The lien must be recorded with the county recorder within 120 days after the project is completed. If the owner or general contractor records a notice of completion, that window shrinks to 60 days after the recording.3Arizona Legislature. Arizona Code 33-993 – Procedure to Perfect Lien; Notice and Claim of Lien; Service; Recording; Definitions A copy of the recorded lien must then be served on the property owner within a reasonable time. Miss either deadline and the lien dies.
After recording, the claimant has six months to file a foreclosure lawsuit. If they don’t, the lien expires automatically.4Arizona Legislature. Arizona Code 33-998 – Limitation of Action to Foreclose Lien; Attorney Fees Filing a cross-claim in another lienholder’s foreclosure action within that same six-month window also counts as timely enforcement.
Owner-Occupant Protection
Under A.R.S. 33-1002, no mechanic’s lien can be recorded against the dwelling of an owner-occupant unless the claimant has a written contract directly with that owner-occupant. A subcontractor hired by the general contractor who never dealt with the homeowner cannot lien the home. This protection cannot be waived by contract. To qualify, the homeowner must have held title before construction began and must live in or intend to live in the home for at least 30 days during the year after the project finishes.
Judgment Liens
A judgment lien arises when someone wins a lawsuit for money damages and records the judgment with the county recorder. Recorded together with an information statement, the judgment becomes a lien on all real property the debtor owns in that county, including property acquired later.5Arizona Legislature. Arizona Code 33-961 – Recording Judgments for Payment of Money
A judgment lien lasts 10 years from the date the judgment was entered. Liens obtained by the state and those securing child support stay in effect until the debt is satisfied or the lien is lifted by court order.6Arizona Legislature. Arizona Code 33-964 – Lien of Judgment; Duration; Homestead; Partial Release of Judgment Lien; Acknowledgment of Satisfaction by Judgment Creditor Once recorded, the lien blocks the debtor from selling or refinancing without addressing the debt. If the debtor doesn’t pay, the creditor can seek a writ of execution to levy the property. Under A.R.S. 12-1551, that writ must be obtained within 10 years of judgment entry, and the window can be renewed for additional 10-year periods.7Arizona Legislature. Arizona Code 12-1551 – Issuance of Writ of Execution; Limitation; Renewal; Death of Judgment Debtor; Applicability
The $400,000 Homestead Exemption
Arizona shields up to $400,000 in equity in a primary residence from most judgment liens. The exemption covers a single-family home, condominium, or mobile home, and a married couple or single person can claim only one homestead.8Arizona Legislature. Arizona Code 33-1101 – Homestead Exemptions When equity in the home is below the exemption amount, the creditor effectively cannot force a sale. The lien still attaches, and it may be collected later if equity grows past the exemption.
Property Tax Liens
Property tax liens are the most powerful liens in Arizona. Under A.R.S. 42-17153, the lien attaches to assessed property automatically on January 1 of each tax year and outranks nearly every other lien and encumbrance, including mortgages. The only exceptions are liens held by the state itself and liens for taxes from other years.9Arizona Legislature. Arizona Code 42-17153 – Lien for Taxes; Time Lien Attaches; Priority
When taxes go unpaid, the county treasurer sells tax lien certificates at auction. A third-party investor who buys a certificate pays the delinquent taxes and earns interest up to 16% per year until the owner redeems.10Arizona Legislature. Arizona Code 42-18204 – Judgment Foreclosing Right to Redeem; Effect Redemption requires paying the delinquent taxes plus accrued interest and statutory fees.
If the lien goes unredeemed for three years after the sale, the certificate holder can file a superior court action to foreclose the right to redeem. The outer deadline is 10 years after the month the lien was acquired.11Arizona Legislature. Arizona Code 42-18201 – Action to Foreclose Right to Redeem; Subsequent Certificates of Purchase by Assignment Federal tax liens are governed separately by the Internal Revenue Code and must be recorded with the county recorder to put third parties on notice.
HOA Assessment Liens
Homeowners associations can place liens on a unit or lot when the owner falls behind on assessments, and the thresholds for foreclosing differ by community type.
In a planned community, the HOA can foreclose the assessment lien once the owner has been delinquent for 18 months or owes $10,000 or more, whichever comes first. Before filing, the board must make reasonable efforts to communicate with the homeowner and offer a payment plan, and it must send a written 30-day delinquency notice by certified mail before turning the account over to an attorney or collection agency.12Arizona Legislature. Arizona Code 33-1807 – Common Expense Liens; Priority; Mechanics’ and Materialmen’s Liens; Notice
In a condominium, the foreclosure threshold is lower: one year of delinquency or $1,200 owed, whichever comes first. The same pre-foreclosure notice and communication requirements apply.13Arizona Legislature. Arizona Code 33-1256 – Common Expense Liens; Priority; Mechanics’ and Materialmen’s Liens; Notice; Applicability
HOA liens sit behind first mortgages, previously recorded liens, and property tax liens. An HOA lien also expires if the association doesn’t initiate enforcement within six years after the full assessment becomes due.
Child Support Liens
Arizona child support orders in Title IV-D cases create an automatic lien on all property the obligor currently owns or later acquires. No separate court judgment is needed.14Arizona Legislature. Arizona Code 25-516 – Lien; Priority; Recording; Information Statement; Payoff Amount; Release The Department of Economic Security perfects the lien by filing a copy of the support order along with an information statement with the county recorder, giving constructive notice to creditors and future buyers.
The lien covers the amount owed at recording plus anything that accrues afterward. It sits behind previously recorded mortgages and deeds of trust but ahead of most other interests. When the case closes, the Department records a lien release in every county where it filed. Releasing the lien on the property does not wipe out the underlying support debt or discharge any separate recorded judgment.
How Priority Works When Liens Compete
Arizona generally follows “first in time, first in right”—whichever lien was recorded first gets paid first. Several statutory exceptions override that default, and that’s where things get complicated.
Property tax liens sit at the top and outrank mortgages, mechanic’s liens, judgment liens, and everything else except liens held by the state itself.
Mechanic’s liens get special treatment. They take priority over all liens and encumbrances that attached after the work began or materials were first delivered, so a mechanic’s lien can leapfrog a mortgage recorded after construction started. A construction lender’s mortgage or deed of trust is protected if it was recorded within 10 days of work commencing.15Arizona Legislature. Arizona Code 33-992 – Preference of Liens Over Subsequent Encumbrances; Professional Services Liens
Judgment liens rank below voluntary liens like mortgages. A recorded judgment lien attaches to the debtor’s property but doesn’t displace existing secured interests. At foreclosure, judgment creditors receive whatever is left after higher-priority liens are satisfied. HOA liens are similarly subordinate to first mortgages and tax liens.
Releasing a Satisfied Lien
Once the debt is paid, the lien must be formally released to clear the title. An unreleased lien can block sales and refinancing even when no money is actually owed.
For mechanic’s liens, A.R.S. 33-1006 requires the lienholder to issue a release within 20 days of receiving full payment. The release must be in recordable form and filed with the county recorder. A lienholder who refuses or fails to release a satisfied lien is liable for $1,000 in statutory damages plus the property owner’s actual damages.16Arizona Legislature. Arizona Code 33-1006 – Release of Lien
Judgment liens must be discharged after payment. The creditor records a satisfaction of judgment with the county recorder and notes the satisfaction on the superior court docket. Under A.R.S. 12-1567, the prevailing party has 40 days from full payment to file the satisfaction. If they don’t, the debtor can move to compel with a supporting affidavit; if granted, the judgment is deemed satisfied.17Arizona Legislature. Arizona Code 12-1567 – Satisfaction of Judgment; Superior Court; Filing Procedures; Hearing; Bond
Tax liens are released when the delinquent taxes, interest, and fees are paid in full. If a third party holds the certificate, redemption runs through the county treasurer.
Removing a Mechanic’s Lien With a Bond
An owner who needs to sell or refinance while a mechanic’s lien dispute is unresolved can post a surety bond to remove the lien from the property. The bond transfers the security from the real estate to the bond itself; it doesn’t resolve the underlying claim.
Under A.R.S. 33-1004, the bond must equal 150% of the amount claimed and must be issued by a surety company authorized to do business in Arizona. Individual sureties are not permitted. Once the bond is recorded with the county recorder, the property is discharged from the lien automatically, whether or not the lien claimant has been served a copy.18Arizona Legislature. Arizona Code 33-1004 – Discharge of Mechanic’s Liens; Bond; Limitations of Actions
If the lien claimant later wins in court, the judgment runs against the bond and its principal, not the property. Total recovery from the bond, including interest, costs, and attorney fees, is capped at the bond’s face amount. Anything above that can only be pursued against the principal personally.
Penalties for Wrongful or Fraudulent Filings
Arizona treats fraudulent liens seriously. Under A.R.S. 33-420, anyone who records a document claiming an interest in real property while knowing (or having reason to know) it is forged, groundless, or contains a material misstatement is liable to the property owner for at least $5,000 or treble the actual damages caused by the recording, whichever is greater. The filer must also pay the owner’s reasonable attorney fees and costs.19Arizona Legislature. Arizona Code 33-420 – False Documents; Liability; Special Action; Damages; Violation; Classification
To clear a wrongful lien, the property owner can file a special action requesting invalidation. If the court agrees, it orders the document expunged from the recorder’s records and may impose additional sanctions. The combination of treble damages and mandatory attorney fee awards is the reason anyone considering a lien filing should verify their claim meets every statutory requirement before recording.
