Full Price Lien vs. Unpaid Balance States
How far a subcontractor's lien can reach is a fundamental question, and different states answer it very differently. Full Price Lien states let the lien attach to the property regardless of what the owner has already paid the general contractor. Unpaid Balance states cap the lien at what the owner still owes. This map shows which rule applies where, and the page below explains what that means for every party on a project.

How the Two Rules Actually Work
The difference looks small on paper but swings the outcome of a payment dispute. Every mechanic's lien statute answers the same underlying question differently: when a subcontractor or supplier is not paid by the general contractor, how much of the owner's property is on the hook for that unpaid bill. Full Price Lien states answer "the full value of what you furnished." Unpaid Balance states answer "only what the owner still owes the GC."
Full Price Lien
The lien attaches to the property for the full, unpaid value of the labor and materials actually furnished, without regard to how much the owner has paid the general contractor. If the GC fails to pay a sub and disappears with the owner's money, the sub's lien still stands against the property. The owner can be exposed to a second payment — first to the GC, then to clear the lien — unless the owner collected proper lien waivers along the way.
Consequences:
- • Subcontractors and suppliers have the strongest lien leverage.
- • Owners must insist on conditional and unconditional lien waivers with every progress payment.
- • Payment bonds, joint checks, and title-company escrow shift the risk off the owner.
- • GCs must track downstream payment carefully; missed payments expose the owner regardless.
Unpaid Balance Lien
The lien can attach only to the amount the owner still owes the general contractor when the lien is perfected. Once the owner has paid the GC in full, following whatever statutory steps the state requires (often a sworn statement identifying all subs and suppliers), the owner's property is insulated from further liens. The sub's recovery then runs against the GC rather than the property.
Consequences:
- • Owners can clear exposure by paying the GC correctly and collecting required documentation.
- • Subs and suppliers must serve notices and perfect liens early, before the owner releases final payment.
- • If the GC is paid and then becomes insolvent, downstream lien claims may have nothing to attach to.
- • Sworn statements, statutory waivers, and timing of notice are disproportionately important.
Special Rules to Watch
A handful of states do not sit cleanly on either side of the line. These exceptions are where payment disputes most often come apart, so they deserve extra attention.
Mississippi — Project-Type Split
Non-residential projects follow the Full Price Lien rule. Residential projects follow the Unpaid Balance rule. Correctly classifying the project at the outset determines how much lien protection exists on the property.
Maine & Maryland — Contract Price Cap
Both are Full Price Lien states, but the total of all mechanic's liens on the project cannot exceed the amount of the prime contract. Subs and suppliers keep full-price protection; owners have a ceiling on aggregate exposure.
Illinois — Sworn Statement Trigger
Illinois applies the Unpaid Balance rule only when the GC has furnished a compliant Sworn Statement listing every subcontractor and supplier owed on the project. Without it, the owner can lose the unpaid-balance limitation entirely.
Other Jurisdictions — Confirm the Statute
A few states — including Florida, Georgia, Massachusetts, and Ohio — blend elements of both rules or use owner-payment defenses tied to proper notice and documentation. Always confirm with state statute and counsel before assuming a category.
How Notice Timing Interacts With Scope
In an Unpaid Balance state, the fund your lien can actually reach is whatever the owner still owes the GC at the moment the lien attaches. That makes the timing of your preliminary or pre-lien notice economically as important as whether you serve it at all. Serving early locks the claim in while the owner still holds the largest portion of the contract balance; waiting to the edge of the statutory window risks the owner paying the GC down in the meantime, shrinking the pot your lien can reach — sometimes to nothing.
Full Price Lien states work differently. The owner's payments to the GC do not reduce the lien, because the property itself is on the hook for the full value of what the subcontractor furnished. Timing the notice is still critical to statutory preservation, but the dollar ceiling does not move with the owner's payment schedule.
Illinois is the textbook illustration. A subcontractor's 90-Day Notice under 770 ILCS 60/24 may be served any time after the subcontract is entered into and must be served within 90 days of last furnishing. Serving at signing is fully compliant and secures the claim against the largest possible unpaid contract balance. Waiting until day 89 is also compliant — and may attach to a materially smaller fund, or none, depending on what the owner has paid the GC in the interim.

Frequently Asked Questions
What is the difference between a Full Price Lien state and an Unpaid Balance state?
In a Full Price Lien state, a subcontractor or supplier's mechanic's lien attaches to the property for the full value of the labor and materials they furnished, even if the owner has already paid the general contractor in full for that work. The owner can, in effect, be required to pay twice to clear the lien. In an Unpaid Balance state, a subcontractor or supplier's lien is capped at the amount the owner still owes the general contractor when the lien attaches. If the owner has fully paid the GC, the subcontractor's lien rights against the property are reduced or eliminated, and the subcontractor's recovery runs through the GC rather than the property itself.
Why does this distinction matter for subcontractors and suppliers?
The distinction determines how much protection your lien actually gives you. In a Full Price Lien state, the property is your security regardless of what the owner has paid upstream. In an Unpaid Balance state, your lien is only as valuable as the funds the owner still owes when you perfect the lien. If the GC has already been paid in full and disappears, you may be left with a lien that attaches to nothing. In Unpaid Balance states, timing and serving proper notices before the owner releases final payment is critical.
Why does this distinction matter for owners and general contractors?
Owners in Full Price Lien states bear significant risk: even after paying the GC, they can face liens from subs and suppliers the GC failed to pay. Lien waivers, joint checks, title company escrow, and requiring the GC to post a payment bond become essential risk-management tools. In Unpaid Balance states, owners are protected once they've fully paid the GC in accordance with statutory requirements and any required sworn statements or lien waiver procedures. GCs working across state lines must adjust their payment and documentation procedures accordingly.
What are the special rules in Mississippi, Maine, and Maryland?
Mississippi applies different rules based on project type. For non-residential projects, Mississippi follows the Full Price Lien approach. For residential projects, it follows the Unpaid Balance approach. Maine and Maryland are Full Price Lien states with a statutory cap: the total lien claim cannot exceed the amount of the prime contract itself. This prevents a scenario where aggregated subcontractor liens exceed what the owner originally agreed to pay for the project as a whole.
What does the "Sworn Statement" rule mean in Illinois?
Illinois is generally categorized as an Unpaid Balance state, but the protection only operates when the general contractor has delivered a proper Sworn Statement identifying all subcontractors and suppliers owed on the project. Without a compliant Sworn Statement, the owner may not receive the benefit of the unpaid-balance limitation and can be exposed to liens beyond what it still owes the GC. Illinois owners should always demand a current Sworn Statement before releasing payment, and subs and suppliers should serve a 90-day Notice to Owner to preserve lien rights regardless.
Does the timing of my preliminary notice affect recovery in an unpaid-balance state?
Yes. An unpaid-balance lien is capped at what the owner still owes the general contractor when the lien attaches. The earlier you serve the preliminary or pre-lien notice, the larger the unpaid contract balance still held by the owner, which sets the ceiling for what your lien can reach. Illinois is the clearest example: the 90-Day Notice under 770 ILCS 60/24 may be served any time after the subcontract is signed, and must be served within 90 days of last furnishing. Serving near the end of that window — 89 days after last furnishing — is still timely under the statute, but by then the owner may have paid most of the contract balance to the GC, leaving little for the lien to attach to. In a Full Price Lien state, timing is purely about statutory preservation because the property is on the hook for the full value furnished regardless of upstream payments.
How does National Lien & Bond help navigate these differences?
National Lien & Bond maintains a nationwide compliance database that tracks each state's lien scope rules, notice requirements, and enforcement procedures. When a project is submitted, we identify whether it falls in a Full Price Lien or Unpaid Balance jurisdiction, flag any special rules (Sworn Statement, contract-price caps, project-type distinctions), and file the appropriate notices and liens to preserve your payment rights. Every notice and lien is attorney-reviewed, so you do not need to track fifty-plus separate rule sets on your own.
