South Carolina Construction Lending Requirements

South Carolina Construction Lien Law Overview

South Carolina’s mechanics lien laws (S.C. Code Ann. § 29-5-10 et. seq.) are purely statutory and demand strict procedural compliance. A mechanics lien is created when a contractor, subcontractor, or supplier improves real property by furnishing labor or materials by virtue of an agreement with, or by consent of, the owner.

The statutory process to enforce a mechanics lien in South Carolina involves three distinct steps: 1) Both filing and serving the Statement of Account (the lien) within 90 days after the claimant last furnished labor or materials, 2) Filing an enforcement lawsuit within six months after the claimant last furnished labor or materials, and 3) Recording a Notice of Lis Pendens to indicate active litigation, also within six months after the claimant last furnished labor or materials.

South Carolina does not enforce sweeping procedural distinctions between residential and commercial projects for the filing of the lien itself. All claimants must strictly adhere to the requirement of both filing and service of the mechanics lien Statement of Account within 90 days after the claimant last furnished labor or materials (S.C. Code Ann. § 29-5-90). However, the state distinguishes claimant tiers: those in direct privity with the owner, and those who are not (who must serve a Notice to Owner — an essential written notice that establishes/preserves lien rights against the owner’s property and traps unpaid funds, subject to South Carolina’s unpaid-balance limitations, pursuant to S.C. Code Ann. § 29-5-40). Furthermore, the state restricts sub-subcontractor claims if the general contractor successfully files a Notice of Project Commencement.

Mortgage Priority

South Carolina provides a highly favorable and protective priority framework for construction lenders, shielding future loan advances from mechanics liens unless strict service requirements are met by the claimant.

• The General Rule: South Carolina generally follows a “first-in-time, first-in-right” priority system. A recorded mortgage holds priority over subsequently filed mechanics liens (S.C. Code Ann. § 29-5-70).
• Future Advances Protection (Lender Safe Harbor): For construction loans, the priority of future disbursements is heavily protected under S.C. Code Ann. § 29-3-50(A). A construction loan mortgage securing future advances is valid and prioritized from the day and hour it is recorded. A mechanics lien is only superior to the lien of a recorded mortgage as to disbursements made after both the filing of the mechanics lien AND formal Rule 4 service on the prior recorded mortgage holder (S.C. Code Ann. § 29-3-50(A)). However, as a risk-management best practice, actual knowledge of a filed lien should still trigger lender controls (e.g., freezing disbursements or demanding a bond).
• Pro-Rata Distribution: If multiple valid mechanics liens are filed and the amount due by the owner to the general contractor is insufficient to pay all lienors, the owner must prorate the available funds among all just claims (S.C. Code Ann. § 29-5-60).
• Establishing Priority: To establish absolute first-lien priority, the construction lender should record the mortgage before any visible work begins. As long as the mortgage is recorded, all subsequent draw disbursements retain first-lien priority over the mechanics lien unless the lender is formally served with the filed lien document. Once the lender is formally served, any subsequent disbursements lose priority to that specific lien.

Retainage Overview

South Carolina law distinguishes completely between public works and private construction regarding retainage.

• Residential (1-4 unit), Multi-Family, and Commercial: For private construction projects, South Carolina does not statutorily regulate or cap the amount of retainage that can be withheld. The percentage of retainage (typically 5% to 10%) and the conditions for its release are governed entirely by the terms of the private construction contract between the owner and the general contractor. Furthermore, there is no statutory mandate to hold private retainage in a separate, interest-bearing escrow account.
• Lender Best Practice: Because private retainage is uncapped by state law, lenders should strictly adhere to the holdback percentages established in their construction loan agreements and the borrower’s prime contract to maintain sufficient financial leverage. Retainage administration should follow the construction contract, loan documents, and any applicable Prompt Payment Act requirements. (Note: The frequently cited 3.5% retainage cap under S.C. Code § 11-35-3030 applies exclusively to public/government projects and has no bearing on private commercial or residential lending).

Prompt Payment Act

The South Carolina Prompt Payment Act (S.C. Code Ann. § 29-6-10 et. seq.) dictates payment deadlines for private construction projects, but allows for significant contractual flexibility and features residential exemptions.

• Exemptions: The Act explicitly does not apply to residential homebuilders, residential improvements of 16 or fewer units, and privately owned improvements not financed by a non-owner (S.C. Code Ann. § 29-6-10).
• Owner to Prime Contractor: If the owner and contractor do not agree otherwise, the owner must pay the contractor within 21 days of receiving a proper pay request (S.C. Code Ann. § 29-6-30).
• Prime to Subcontractor: The prime contractor must pay its subcontractors within 7 days of receiving payment from the owner (S.C. Code Ann. § 29-6-30).
• Contractual Override & Penalties: For private construction projects, owners, contractors, and subcontractors are explicitly permitted to agree by contract to payment periods and interest rates different from the statutory defaults, and those contractual provisions shall control only if the statutory requirements of S.C. Code §§ 29-6-30 and 29-6-50 are specifically waived by section number in conspicuous bold-faced or underlined type (S.C. Code Ann. § 29-6-50). If payment is delayed beyond the applicable deadline, the unpaid balance accrues interest at 1% per month. However, this interest is only due if the person being charged was notified of the provisions of this statute at the time the request for payment was made.
• Lender Impact: Draw administrators handling commercial and large multi-family loans should review the prime contract for customized payment terms. Unwarranted delays in loan funding that cause the owner to miss the contractual or 21-day statutory deadline can trigger the 1% monthly interest penalty.

Title Practices

Under South Carolina law, state statutes do not require title companies to administer construction loan disbursements. Lender-managed disbursements (or third-party draw administration) represent the standard industry practice.

To maintain first lien priority, verifying title and monitoring for liens at each draw is the primary best practice. Construction lenders have three primary options to achieve this:

• Lien monitoring subscription services
• Title updates (which check public records but provide no insurance)
• Title endorsements

Strategic Benefit of Title Endorsements: It is highly recommended that construction lenders utilize ALTA 32 (Construction Loan) and ALTA 33 (Disbursement) title endorsements. While S.C. Code Ann. § 29-3-50(A) protects future advances until the lender is formally served with a lien, relying solely on administrative mail screening for service is risky. Utilizing an ALTA 33 date-down endorsement before funding every draw shifts the liability of discovering filed liens from the lender to the title insurer. Regardless of the method chosen, leveraging these tools to clear encumbrances and verify public filings prior to releasing every single draw is crucial to mitigating priority risk.

Lien Waivers

South Carolina has no statutory lien waiver forms and waiver enforceability depends on ordinary contract principles, including clarity, consideration, payment status, and the specific language of the waiver.

Lien Waiver Summary

Because South Carolina does not prescribe statutory lien waiver forms, their enforceability is determined by the explicit language within the contract.

• Advance Waivers: South Carolina law does not explicitly prohibit advance lien waivers (waiving rights before work begins or before payment is made) by statute. However, relying on blanket advance waivers is highly risky, frequently challenged in court for lack of consideration, and frowned upon by the industry.
• Best Practice: Lenders should rely on heavily vetted, custom waiver forms. It is strongly recommended to enforce a strict draw-by-draw exchange using Conditional Waivers for the current draw amount (conditioned strictly upon the clearance of funds) and Unconditional Waivers for previously funded draws to definitively prove that payment reached the claimant.

Lien Waiver Notarization

South Carolina law does not require lien waivers to be notarized to be considered legally valid and effective. A signed, written agreement is sufficient.

Notices

Notice of Commencement (or similar like event)

Recognized by State?

Yes (Notice of Project Commencement).

Who Files

Any person entering into a direct agreement for the improvement of real property (typically the General Contractor, or the Owner).

When Must it be Filed

Within 15 days of the commencement of work (S.C. Code Ann. § 29-5-23).

Appoint a Designee

No statutory provision for a third-party designee, but the name and address of the owner and contractor are required (S.C. Code Ann. § 29-5-23).

Posted on Jobsite

Yes. A “Location Notice” must be posted at the job site. This notice must contain the specific statement: “The contractor on the project has filed a notice of project commencement at the county courthouse” along with the name and address of the contractor and owner (S.C. Code Ann. § 29-5-23).

Effect

The Notice of Project Commencement is optional. If properly filed and posted, it activates notice-of-furnishing requirements for certain remote claimants. Failure to file does not invalidate the project; it merely removes those statutory notice protections.

Preliminary Lien Notifications

• Notice to Owner: Any subcontractor, materialman, or laborer who does not have a direct contract with the property owner must serve a written “Notice to Owner” detailing the value of the materials or labor furnished (S.C. Code Ann. § 29-5-40). The Notice to Owner is an essential written notice for non-privity claimants that establishes/preserves lien rights against the owner’s property and traps unpaid funds, subject to South Carolina’s unpaid-balance limitations. If the owner has paid the GC in full before receiving the notice, the sub-tier claimant has no lien rights against the property.
• Notice of Furnishing Labor or Materials: If a Notice of Project Commencement is filed, sub-subcontractors and suppliers to subcontractors must serve a Notice of Furnishing upon the general contractor to preserve their lien rights (S.C. Code Ann. § 29-5-20(B)).

Notice of Completion (or similar like event)

• Recognized by State? No. South Carolina does not utilize a statutory Notice of Completion to truncate or alter the deadline for contractors to file mechanics liens. The filing window strictly remains 90 days from the individual claimant’s last date of furnishing.

Additional State-Specific Notices

• Bonding Off a Lien: Under S.C. Code Ann. § 29-5-110, an owner or any other interested party may discharge the lien from the property by filing an undertaking (a surety bond) equal to one and one-third (133%) times the lien amount. This is a critical remedy for lenders. If a lien halts disbursements, demanding the borrower to bond off the lien immediately clears the title and restores the lender’s priority.
• Notice of Non-Responsibility: Under S.C. Code Ann. § 29-5-80, if an owner (or a fee-owner in a tenant leasehold situation) has not authorized the construction, they may prevent a lien from attaching to their interest by serving a written notice that they will not be responsible for the improvements.

Document References

• Notice of Project Commencement: A statutory document filed with the county clerk or register of deeds within 15 days of starting work. It benefits the lender by forcing sub-subcontractors to identify themselves, limiting hidden lien risk. The Notice of Project Commencement is optional. If properly filed and posted, it activates notice-of-furnishing requirements for certain remote claimants. Failure to file does not invalidate the project; it merely removes those statutory notice protections (S.C. Code Ann. § 29-5-23).
• Notice to Owner: An essential written notice sent by subcontractors and suppliers not in direct contract with the owner. It establishes/preserves lien rights against the owner’s property and traps unpaid funds, subject to South Carolina’s unpaid-balance limitations. If not sent before the owner pays the GC in full, the claimant has zero lien rights against the property (S.C. Code Ann. § 29-5-40).
• Statement of Account (Mechanics Lien): The formal document filed with the clerk of court or register of deeds to perfect the encumbrance. It requires both filing and service on the owner within 90 days after the claimant last furnished labor or materials, otherwise the lien is dissolved (S.C. Code Ann. § 29-5-90).

Contractor Licensing & Bond Requirements

South Carolina heavily regulates contractor licensing at the state level through the South Carolina Department of Labor, Licensing and Regulation (LLR).

• Commercial / General Contractors: A General or Mechanical Contractor license is required when the total cost of construction exceeds $10,000 (S.C. Code Ann. § 40-11-30).
• Residential Builders: A Residential Builder license or Residential Specialty Contractor registration is regulated separately under Chapter 59 (S.C. Code Ann. § 40-59-30).
• Surety Bonds: Current LLR guidance requires residential builders to maintain a $15,000 surety bond and identifies separate $10,000 and $5,000 bond requirements for certain residential specialty contractors/registrants when applicable (S.C. Code Ann. § 40-59-50).
• License Lookup: Lenders should verify credentials via the official state portal: South Carolina LLR Licensee Lookup.
