Lien Waiver: What Homeowners Need to Know

A lien waiver is a legal document signed by a contractor, subcontractor, or material supplier confirming that they have received payment and, in exchange, waive their right to file a mechanic's lien against the property for the amount paid. Lien waivers are one of the primary tools homeowners use to protect themselves from lien claims after making payments to their general contractor.

The reason lien waivers matter is that in most states, including Arizona, subcontractors and suppliers have the right to file a mechanics lien against your property even if you paid your general contractor in full. If the general contractor failed to pay the subcontractor or supplier, the lien attaches to your property title regardless of whether you were at fault.

At Phoenix Home Remodeling, collecting lien waivers from subcontractors and suppliers is a standard part of our payment and closeout process. We provide conditional and unconditional lien waivers to our clients as payments are made and the project closes out.

Because Arizona's mechanics lien law creates a direct relationship between the property owner and any party who provided labor or materials to improve the property, regardless of who contracted with them directly. If you hired a general contractor who hired a plumber, and the general contractor took your payment but did not pay the plumber, the plumber can file a lien on your property. Your only recourse is to take action against the contractor who did not pay. This is why lien waivers collected at the time of payment are critical protection for homeowners.

• Conditional waiver on progress payment: Waives lien rights through a specified date, but only becomes effective when the payment actually clears. Used for progress payments during construction. This is the most common form used during active construction.

• Unconditional waiver on progress payment: Waives lien rights through a specified date unconditionally, regardless of whether payment has actually been received. Only appropriate after a check has fully cleared. More valuable to the homeowner but requires trust that payment has been received.

• Conditional waiver on final payment: Waives all remaining lien rights upon final payment clearing. Used at project completion. Conditioned on the final payment check clearing the bank.

• Unconditional waiver on final payment: Waives all remaining lien rights unconditionally. The most complete protection for the homeowner and appropriate only after final payment has been confirmed received.

• Who should provide them: Ideally, your general contractor collects waivers from all subcontractors and suppliers on your behalf and provides them to you as part of the payment cycle. This is the professional standard. Ask your contractor specifically how they handle lien waiver collection before signing a contract.

No. Your contract is with the general contractor. Subcontractors and suppliers have their own lien rights that exist independently of your contract terms. The contract may specify that the contractor is responsible for paying all subcontractors, but if they fail to do so, your property is still at risk. Lien waivers collected as payments are made are the operational protection, not contract language alone.

In Arizona, a mechanics lien must be filed within 120 days after the last day work was performed or materials were supplied. Once filed, the lien claimant has six months to foreclose on the lien or it expires. This creates a window of exposure after your project closes out during which previously unpaid parties could still file. Collecting final unconditional lien waivers from all parties closes this exposure.

We collect lien waivers from our subcontractors and suppliers on a payment-cycle basis. At project closeout, we provide our clients with a final unconditional lien waiver covering all work and materials. This is part of our standard project closeout process and is something you can request documentation of at any point during the project.

• Do you collect lien waivers from your subcontractors and suppliers as payments are made?
• Will you provide me with copies of subcontractor lien waivers at each payment milestone?
• What lien waiver will I receive at project final?
• How do you handle preliminary notices that arrive from your subcontractors or suppliers?
• Are there any parties on this project who have already filed a preliminary notice?
