5.1 Mechanics' Lien Rights, Scope & Priority in South Carolina

Statutory Foundation and Nature of Mechanics' Liens

In South Carolina, mechanics' liens are governed by S.C. Code Title 29, Chapter 5, beginning at § 29-5-10. A mechanics' lien is a statutory claim that secures payment for people who furnish labor or materials for the erection, alteration, or repair of a building or structure on real estate.

A mechanics' lien is an in rem security interest against the improved property itself, not just a personal claim against the party who ordered the work. Because it clouds title, it can halt loan draws, sales, and refinancing, which makes it one of the strongest payment remedies in construction.

Strict compliance: The lien is a creature of statute. A claimant who misses a statutory deadline or service step, such as the 90-day filing and service rule in § 29-5-90 or the six-month suit rule in § 29-5-120, loses the lien. Section 29-5-100 does forgive inaccuracies in the account or property description, unless the claimant willfully and knowingly claimed more than was due.

Who Is Entitled to a Mechanics' Lien?

1. Contractors with the owner (§ 29-5-10(a)). A person owed for labor performed or furnished, or for materials furnished and actually used, by agreement with or consent of the owner, or of someone with authority from the owner, has a lien on the building and on the owner's interest in the lot. The statute defines labor broadly. It includes:
   • preparing plans, specifications, and design drawings
   • site preparation such as grading, excavating, filling, paving, drainage, and utility lines
   • disposal of construction and demolition debris
   • private security guard services at the site
2. Laborers, mechanics, subcontractors, and material suppliers (§ 29-5-20). Anyone furnishing labor or material for an improvement authorized by the owner has a lien, subject to existing liens of which he had actual or constructive notice. Sub-subcontractors and suppliers to subcontractors are covered too. Their recovery can be capped by the notice rules in § 29-5-20(B) when a Notice of Project Commencement has been filed (Section 5.2).
3. Equipment lessors (§ 29-5-22). A person who supplies tools, appliances, machinery, or equipment for use on the building is treated as furnishing material, to the extent of the equipment's reasonable rental value for the period of actual use.
4. Surveyors (§ 29-5-21(A)). A surveyor who surveys real estate by agreement with the owner has furnished material for the improvement.
5. Owner's notice (§ 29-5-40). A laborer or supplier hired by someone other than the owner can notify the owner in writing of the labor or material furnished. The lien then attaches against the owner, but the total of all liens can never exceed what the owner owes on the contract price. A claimant who gives this notice is paid ahead of the contractor who hired it, and later payments by the owner to that contractor do not reduce the claim (§ 29-5-50).

An owner who did not contract for the work can also serve a written notice of nonresponsibility on the person furnishing labor or materials. That notice blocks liens for labor or materials not yet furnished (§ 29-5-80).

Property Subject to Liens: Private vs. Public Works

Payment protection on public projects

Public property cannot be liened and sold to satisfy a construction debt, so South Carolina protects subcontractors and suppliers with payment bonds:

• S.C. Code § 29-6-250: When a governmental body (a state entity or a local political subdivision) is a party to a contract to improve real property for more than $50,000, it must require a labor and material payment bond in the full contract amount. The bond must be secured by cash or issued by a surety licensed in South Carolina with an "A" minimum Best's rating. A "B+" rated bond may be allowed, with written justification, for contracts under $100,000.
• S.C. Code § 11-35-3030: State construction contracts under the Procurement Code require 100% performance and payment bonds. The agency may waive them at $50,000 or less if the State is otherwise protected.
• Federal projects in South Carolina, such as military installations, fall under the federal Miller Act (40 U.S.C. §§ 3131–3134). The FAR currently requires performance and payment bonds on construction contracts over $150,000.

Lien Priority Against Mortgages (§ 29-5-70)

South Carolina ties a mechanics' lien's priority against mortgages to the filing of the lien statement.

§ 29-5-70: Except as provided in § 29-3-50, a mechanic's or materialman's lien "is not enforceable against any mortgage recorded before the filing of the notice pursuant to Section 29-5-90 setting forth the statement of account upon which the lien is based."

What that means in practice:

1. Any mortgage recorded before the lien statement is filed has priority over the lien, whether it was recorded before or after work started.
2. The § 29-3-50 exception: A recorded mortgage that secures future advances keeps its recording-date priority for all advances, up to its stated maximum. But a mechanics' lien becomes superior to a prior recorded mortgage for loan disbursements made after the lien is filed under § 29-5-90 and served on all prior recorded mortgage holders under SCRCP Rule 4. This is one reason construction lenders collect lien waivers with every draw and stop funding once a lien is served.
3. Recording speed matters. A claimant that waits until day 89 to file loses priority to every mortgage recorded in the meantime. Filing promptly protects the lien's position.
4. Among lien claimants, if the amount the owner owes the contractor is not enough to pay all lienors, the owner must prorate it among the valid claims (§ 29-5-60(A)).

How Contractor Licensing Affects Lien and Payment Rights

• License number on the lien (§ 29-5-15(A)). To file a mechanics' lien, a contractor that must be licensed or registered has to prove it to the clerk or register of deeds by recording its license or registration number on the lien document.
• Frivolous liens (§ 29-5-15(B)). A contractor who files a frivolous lien faces a fine of up to $5,000, loss of license or registration, or both.
• No suit on the contract (§ 40-11-370(C)). An entity without a required license may not bring an action at law or in equity to enforce the provisions of a contract. The same applies to an entity that contracts in a name other than the one on its license.
• Working beyond the license group is a separate licensing violation. Section 40-11-110(A)(21) makes contracting beyond the group limit or outside the classification a ground for discipline.

Practical Exam Scenarios

Scenario 1 — Public middle school. Coastal Mechanical LLC installs a $180,000 HVAC system in a new county public middle school. The general contractor fails and does not pay Coastal's final $45,000. Coastal cannot lien the school, which is public property. Its remedy is a claim on the contractor's labor and material payment bond. Section 29-6-250 requires that bond on a governmental contract over $50,000.

Scenario 2 — Unlicensed builder. An entity with no CLB license performs $60,000 of commercial tenant finish work, then records a lien when the owner withholds $20,000. The entity cannot meet the license-number requirement of § 29-5-15, and § 40-11-370(C) bars any action to enforce the contract. It also faces citations, civil penalties, and possible misdemeanor charges.

Scenario 3 — Equipment lessor. Palmetto Heavy Equipment rents two excavators and a bulldozer to an earthwork subcontractor on a private shopping center and is not paid $22,000 in rent. Under § 29-5-22, Palmetto is treated as a material supplier to the extent of the reasonable rental value for the period of actual use, so it may claim a lien. The notice rules in § 29-5-20(B) may cap its recovery if a Notice of Project Commencement was filed.
