Lien Waivers
Lien waivers protect you and your lender from contractor liens on your property. This guide explains the four types of lien waivers, when to use each, and how to collect them properly.
If you're managing your own construction loan, you've probably heard your lender mention lien waivers. For many first-time owner-builders, lien waivers are one of the most confusing parts of the process. This guide explains exactly what lien waivers are, why your bank requires them, and how to collect and manage them properly throughout your build.
A lien waiver is a legal document signed by a contractor, subcontractor, or supplier that releases their right to place a mechanic's lien on your property. A mechanic's lien is a legal claim that contractors and suppliers can file against your property if they aren't paid for their work or materials.
Here's why this matters: if a contractor files a mechanic's lien on your property, it can cloud your title, prevent you from selling or refinancing, and create significant legal headaches. Your construction lender knows this, which is why they require lien waivers before releasing draw funds — they're protecting their collateral (your property) from being encumbered by liens.
Important: Lien laws vary significantly by state. The specific requirements for lien waivers — including the required language, timing, and who must sign — differ depending on where you're building. Consult a local attorney if you have questions about lien waiver requirements in your state.
There are four standard types of lien waivers, and understanding the difference between them is critical:
| Type | When Used | What It Means |
|---|---|---|
| Conditional Waiver on Progress Payment | Before payment | Waives lien rights if payment is received |
| Unconditional Waiver on Progress Payment | After payment clears | Permanently waives lien rights for work to date |
| Conditional Waiver on Final Payment | Before final payment | Waives all lien rights if final payment is received |
| Unconditional Waiver on Final Payment | After final payment clears | Permanently waives all lien rights |
Conditional waivers are used when you haven't paid yet. They say, in effect, "I waive my lien rights if I receive the payment described in this document." They protect the contractor — if the check bounces or payment doesn't come through, the waiver is void.
Unconditional waivers are used after payment has cleared. They permanently release lien rights and cannot be undone. Never sign (or accept) an unconditional waiver before payment has actually cleared your bank.
Progress payment waivers cover work done to date (up to a specific date or draw number). Final payment waivers cover all work on the entire project.
This is where many owner-builders get tripped up. You need lien waivers from:
Even if you paid a subcontractor directly, they can still file a lien if the general contractor didn't pay them. And material suppliers who delivered materials to your site can file liens even if you never had a direct contract with them.
Best practice: Keep a running list of every contractor, subcontractor, and supplier for each phase of construction. Before you pay anyone, get a conditional lien waiver. After payment clears, follow up with an unconditional waiver.
Timing matters with lien waivers. Here's the recommended approach:
Before paying: Request a conditional lien waiver from every contractor and supplier. This is standard practice — most contractors expect it and will have their own form ready.
When paying: Include a copy of the conditional lien waiver with your check or payment. Some contractors will sign it when they receive payment; others prefer to sign before.
After payment clears (3–5 business days): Follow up to get an unconditional lien waiver. This is the document your lender actually wants to see.
Before each draw: Compile all lien waivers for the phase you're drawing on. Your lender will typically want unconditional waivers for all work paid to date, plus conditional waivers for any amounts still owed.
Construction lenders typically require lien waivers as part of each draw request. Specifically, most lenders want:
Some lenders have their own lien waiver forms they want you to use. Others accept any state-compliant form. Check with your loan officer early in the process to understand exactly what they require.
Accepting verbal waivers. Lien waivers must be in writing and signed. A contractor saying "don't worry, I won't file a lien" is meaningless.
Using the wrong type. Using a conditional waiver when your lender wants an unconditional one (or vice versa) will cause your draw to be delayed.
Missing suppliers. Many owner-builders collect waivers from their contractors but forget about material suppliers. A lumber yard that delivered $50,000 in materials can file a lien even if you paid your framing contractor in full.
Not dating the waivers correctly. Lien waivers need to cover the right time period. A waiver dated before work was completed won't cover that work.
Losing track of who signed what. With multiple contractors and multiple draws, lien waiver management can get complicated quickly. Keeping everything organized in one place is essential.
DrawBridge is designed to make lien waiver management straightforward for owner-builders. You can upload lien waivers as PDFs, organize them by contractor and draw number, and attach them directly to draw requests. When you submit a draw to your bank, your loan officer can see all the attached waivers in their portal.
This eliminates the common problem of submitting a draw request and then having your bank come back asking for missing waivers — everything is in one place from the start.
Lien waivers are a critical part of the construction loan process, but they don't have to be overwhelming. The key points to remember:
DrawBridge organizes everything your bank needs — from photos to lien waivers.
