South Carolina lien waivers

South Carolina runs a lighter statutory regime than its neighbors. The state does not prescribe waiver forms, so AIA-style language is enforceable, and there is no front-loaded preliminary notice for parties in direct contract with the owner. Subs and suppliers without privity, however, have to serve a Notice of Furnishing on the owner within 90 days of starting work to preserve their lien rights, and every claimant on the job has 90 days from last labor or materials to record a Statement of Lien. Missing either deadline is the most common way builders and their subs lose lien rights in the state.

The statute

South Carolina mechanics-lien practice is codified at S.C. Code Ann. § 29-5-10 et seq. Section 29-5-10 grants a lien to “any person to whom a debt is due for labor performed or furnished or for materials furnished and actually used” in the erection, alteration, or repair of any building or structure on real property, as well as for related improvements like grading and paving. The lien attaches to the building and the lot of land on which it sits, with priority dating back to the day the labor or materials were first furnished on the project.

The chapter has stayed largely stable for decades, with periodic amendments to clarify procedure and add the optional Notice of Project Commencement regime. Compared to Tennessee, North Carolina, or Georgia, the South Carolina lien statute is shorter, less procedurally elaborate, and more permissive on form, which makes it relatively friendly to builders who run a clean process and relatively unforgiving to those who do not pay attention to the notice deadlines that do exist.

No statutory waiver forms

South Carolina does not prescribe a statutory waiver form. Any plainly worded waiver is enforceable as long as it identifies the project, the claimant, the amount and period covered, and the payment that triggers the release. AIA G706 and G707 work without modification, generic conditional and unconditional progress waivers work, and lender or title-company forms work. The only real constraint is the same one that applies everywhere: a vendor who signs an unconditional waiver before payment has waived lien rights for that period regardless of whether the funds ever arrive.

Because the state does not prescribe text, the discipline question for a builder is not which form to use but whether the conditional and unconditional waivers are issued and collected on the schedule the draw process requires. South Carolina projects that go sideways at closeout almost always do so because nobody chased the unconditional waivers after each interim payment, not because the form was wrong.

Notice of Furnishing

Section 29-5-20 requires subcontractors and suppliers without privity of contract with the owner to serve a written Notice of Furnishing on the owner within 90 days of first furnishing labor or materials. The notice has to identify the claimant, describe the work or materials furnished, and identify the party that engaged the claimant. Service can be by certified mail, personal delivery, or the other means the statute allows.

Once a Notice of Furnishing has been served, the owner is deemed to have notice of the claimant’s potential lien claim. That matters because of § 29-5-40, which protects an owner who pays the prime contractor in good faith without notice of unpaid downstream claims. Until a Notice of Furnishing is on file, an owner can pay the prime in full and reduce the pool of money against which a sub can ultimately claim. After the Notice of Furnishing is served, the owner is on notice and any further payment to the prime is at the owner’s risk to the extent the sub is unpaid.

In-privity versus without-privity

The Notice of Furnishing requirement only applies to claimants without privity of contract with the owner. The original contractor and any sub or supplier in direct contract with the owner do not have to serve a Notice of Furnishing because they are already known to the owner. Second-tier subs (those contracting with the original contractor rather than the owner) and any tier below them do have to serve the notice.

This distinction is the most common procedural pitfall in the state. A builder running a residential project as the prime contractor knows the in-privity exception covers the builder itself. The builder’s subs, however, are almost always second-tier (they contracted with the builder, not with the owner) and they are the ones who need to file the Notice of Furnishing. A builder who assumes the in-privity exception covers the entire project and tells subs they do not need to send notices is creating a future closeout problem. The in-privity rule protects the prime; it does nothing for the subs working under the prime.

The right move at kickoff is for the builder to remind every sub in writing that the sub is responsible for serving its own Notice of Furnishing within 90 days of first furnishing labor or materials, and to ask for a copy of each notice for the project file. A sub that fails to serve the notice and later cannot lien is a sub looking for other ways to apply pressure on the builder, which is the problem the discipline is designed to prevent.

Filing deadlines

Section 29-5-90 sets the deadline to file the Statement of Lien at 90 days after the claimant last performed labor or furnished materials on the project. The Statement of Lien is recorded in the office of the register of deeds (or clerk of court in counties without a register) for the county where the property sits, and it has to include a description of the property, the amount claimed, and the identity of the owner.

Once the Statement of Lien is filed, § 29-5-120 requires the claimant to commence an action to foreclose the lien within six months of the filing date. Failing to file the foreclosure action inside the six-month window causes the lien to lapse automatically, and the lien cannot be revived by a late filing. The combined effect is a tight enforcement timeline: 90 days from last work to file, then six months to sue, then the lien is gone.

The owner’s liability cap

Section 29-5-40 caps the owner’s liability to subs and suppliers at the amount the owner still owes the prime contractor at the time the owner receives notice of an unpaid claim. An owner who has already paid the prime in full, before receiving any Notice of Furnishing or other written notice, is generally protected from further claims by downstream subs.

This is the operative reason the Notice of Furnishing is so important. A sub who serves the notice promptly puts the owner on notice while there is still money in the project that has not yet been disbursed to the prime, and the sub can therefore reach that money through a lien. A sub who waits and serves the notice after the owner has finished paying the prime in good faith finds that the practical pool against which the lien can attach has shrunk to whatever equity in the property is not already encumbered by the construction loan and prior recorded interests.

Notice of Project Commencement

Section 29-5-25 allows an owner to file an optional Notice of Project Commencement in the office of the register of deeds before construction begins. The notice describes the project, identifies the owner and the prime contractor, and triggers procedural deadlines for any sub or supplier who wants to preserve lien rights. When a Notice of Project Commencement has been filed, subs and suppliers serve their Notice of Furnishing on a coordinated schedule keyed to the project commencement notice rather than to the date each sub starts work.

The mechanism is used most often on larger residential developments and commercial projects where the owner wants the certainty of knowing every potential lien claimant has surfaced within a defined window. On a single custom home, the cost and procedural overhead of the project commencement notice usually outweighs the benefit, and most South Carolina residential builders operate without one. Builders working on subdivision developments or larger residential projects funded through institutional lenders should expect the lender or title company to ask whether a Notice of Project Commencement has been filed.

Bonded projects

On projects covered by a payment bond, mechanics lien rights against the real property generally do not apply because the bond stands as a substitute remedy for unpaid claimants. The bond claim deadlines under the bond and the underlying contract typically mirror the lien deadlines, with notice requirements and a 90-day window from last work to assert a claim against the bond.

For a residential builder working on a bonded project (less common than on commercial or public work but it does come up on larger spec developments), the practical workflow is the same as on an unbonded project. Conditional waivers ship with each draw, unconditional waivers come back after payment clears, and the documentation gets handed to the bond company at closeout the same way it would be handed to the title company on an unbonded project.

A clean monthly draw cycle

On a typical South Carolina custom home, the clean cycle looks like this each month. At kickoff the builder confirms with each sub that the sub will serve a Notice of Furnishing within 90 days of first furnishing labor or materials and will provide the builder a copy for the project file. As work progresses, each sub submits an invoice for the period along with a conditional progress waiver identifying the property, claimant, customer, payer, amount, and period covered. The builder assembles the draw package with each invoice and conditional waiver plus the prior period’s unconditional waivers, and the lender funds the draw.

Once payment clears, the builder requests an unconditional progress waiver from each sub and stores the returned waiver in the project file. The next draw’s package includes those unconditional waivers as proof the prior period is closed. At project close the same sequence runs with conditional and unconditional final waivers. The deadline calendar runs independently: any sub who has not been paid by day 75 from last work gets a reminder that day 90 is the lien-filing cutoff, and the builder coordinates with the sub on whether payment is imminent or whether the sub intends to file.

Common pitfalls

The single most common procedural mistake on South Carolina residential projects is second-tier subs missing the 90-day Notice of Furnishing. The sub assumes someone (usually the builder) is handling the notice on the sub’s behalf, nobody actually files it, and by the time the sub realizes there is a payment problem the 90-day window has closed. The fix is making it a clearly assigned sub-side responsibility at kickoff and asking for a copy of the notice as part of the standard onboarding package.

The second pitfall is builders assuming the in-privity exclusion at § 29-5-20 protects the entire project. It does not. The exclusion only protects the prime contractor and any party in direct contract with the owner. Every sub and supplier below that line is on the Notice of Furnishing track. A builder who uses the in-privity exclusion as a reason to skip the discussion with subs is creating a closeout problem that surfaces several months later when an unpaid sub discovers the lien window has expired.

The third pitfall is missing the 90-day filing window from last work. Subs sometimes coast past the deadline because the builder has promised a payment that never quite arrives, and the sub holds off on filing as a relationship gesture. South Carolina has no grace period: 91 days after last work, the lien rights are gone. The discipline is to treat day 75 as a hard internal review date and to file the lien on day 89 if payment has not arrived, regardless of the relationship considerations. A timely-filed lien can always be released when payment clears; a missed deadline cannot be cured.
