South Carolina Bonding Requirements Overview
South Carolina's public construction bonding requirements are governed by two primary statutes: SC Code § 29-6-250 (the South Carolina Payment Bond Act) and the South Carolina Consolidated Procurement Code (SC Code Title 11, Chapter 35). Together, these statutes establish the framework for when and how surety bonds must be furnished on publicly funded construction projects throughout the Palmetto State. Understanding these requirements is essential for any contractor working on — or hoping to bid on — public projects in South Carolina.
Under SC Code § 29-6-250, a payment bond is required on all public construction projects in South Carolina that exceed $50,000. This threshold is significantly lower than many other states, reflecting South Carolina's strong commitment to protecting subcontractors, laborers, and material suppliers on public projects. The payment bond must be in an amount equal to the full contract price and guarantees that the contractor will pay all parties who furnish labor, materials, or services on the project.
Performance bonds are governed separately under the SC Procurement Code (SC Code § 11-35-3030), which requires performance bonds on public construction contracts exceeding $100,000. Unlike some states where performance bonds are discretionary, South Carolina mandates them by statute on qualifying public projects. The performance bond must be in an amount equal to 100% of the contract price and guarantees that the contractor will complete the project in accordance with the contract documents, plans, and specifications.
South Carolina is also notable for requiring a $15,000 contractor license bond for residential builders and residential specialty contractors. This bond is administered through the SC Residential Builders Commission and protects consumers against financial loss caused by a contractor's failure to comply with the South Carolina Residential Builders Act (SC Code Title 40, Chapter 59). The bond requirement applies to all residential builders, including general contractors and specialty contractors who perform work on residential properties. General and mechanical contractors licensed through the SC Contractors' Licensing Board (which handles commercial and industrial work) are not subject to a statewide license bond requirement, though individual municipalities may impose their own bonding conditions.
South Carolina's bonding framework also interacts with the state's prevailing wage and procurement policies. The SC Procurement Code governs how state agencies, counties, school districts, and other political subdivisions solicit and award construction contracts, and it establishes uniform bonding standards that apply across all levels of government in the state.
Bid Bonds in South Carolina
A bid bond is a contract surety bond submitted with a contractor's bid on a construction project. It guarantees two things: first, that the contractor will honor their bid price and enter into the contract if awarded the project; and second, that the contractor will provide the required performance and payment bonds upon contract execution. Bid bonds protect project owners from frivolous or unreliable bids and ensure that the bidding process is competitive and credible.
In South Carolina, bid bonds are commonly required on public construction projects bid through the state's competitive sealed bidding process under the SC Procurement Code. Most invitations for bids (IFBs) issued by South Carolina governmental entities specify that a bid bond or bid security must accompany the bid submission. The typical bid bond amount is 5% of the bid price, consistent with standard industry practice and the requirements of many South Carolina state agencies and municipalities.
South Carolina's bid bond requirements apply across a wide range of public project types, including:
- South Carolina Department of Transportation (SCDOT) highway, bridge, and road projects
- School district construction and renovation projects
- County and municipal building and infrastructure projects
- Water and wastewater treatment facility construction
- University of South Carolina, Clemson University, and other public university campus projects
- State agency facility construction managed by the SC Department of Administration
- Port Authority and coastal infrastructure projects

We issue bid bonds at no charge for South Carolina contractors, whether you have an existing bonding line or are applying for the first time. This ensures you never have to pay for the opportunity to compete on a project.
Performance Bonds in South Carolina
A performance bond guarantees that the contractor will complete the construction project in accordance with the contract documents, plans, specifications, and timeline. If the contractor defaults — by abandoning the project, performing substandard work, or failing to meet contractual deadlines — the surety is obligated to step in to ensure the project is completed.
Under the SC Procurement Code (SC Code § 11-35-3030), performance bonds are required on South Carolina public construction contracts exceeding $100,000. This is a statutory mandate, not a discretionary requirement. The performance bond must be in an amount equal to 100% of the contract price. This requirement applies to all state agencies, and most counties, municipalities, and school districts in South Carolina follow the Procurement Code's bonding standards as well.
Performance bonds are routinely required on a wide range of South Carolina public projects, including:
- SCDOT highway and bridge construction and rehabilitation projects
- Public school construction and major renovation projects
- County and municipal infrastructure projects (roads, utilities, public facilities)
- State government building construction and renovation
- Public university and college campus construction
When required, the performance bond amount is set at 100% of the contract price, consistent with industry standards and the practice under the federal Miller Act. The performance bond remains in effect until the project is substantially complete and accepted by the owner. Some South Carolina contracts also include a maintenance or warranty provision extending beyond substantial completion, typically for one to two years.
Performance bond premiums for South Carolina contractors generally range from 1% to 3% of the contract price, depending on the contractor's financial strength, credit history, experience, and the project's size and complexity. Performance and payment bonds are typically issued together as a matched pair, and the premium covers both bonds.
Payment Bonds in South Carolina
The payment bond is a critical component of South Carolina's public construction bonding framework. SC Code § 29-6-250 requires a payment bond on every public construction project in the state that exceeds $50,000. The payment bond guarantees that the contractor will pay all subcontractors, laborers, and material suppliers who furnish labor, materials, or services on the project.
This requirement exists because mechanic's liens cannot be placed on public property in South Carolina. On private projects, subcontractors and suppliers who are not paid can file a mechanic's lien under SC Code § 29-5 to secure their interest in the property. But this remedy is not available on public projects. The payment bond serves as a substitute for mechanic's lien rights, ensuring that those who contribute labor and materials to a public project have a financial remedy if the contractor fails to pay them.
Key Requirements Under SC Code § 29-6-250
The payment bond must meet several specific requirements under South Carolina law:
- Bond amount: The payment bond must be in an amount equal to the full contract price.
- Threshold: Required on all public construction projects exceeding $50,000.
- Surety qualification: The surety issuing the bond must be authorized to do business in the state of South Carolina and must meet the financial requirements of the contracting governmental entity.
- Bond availability: The payment bond must be available for inspection by potential claimants, allowing subcontractors and suppliers to verify the bond's existence and identify the surety.
Notice Requirements for Payment Bond Claimants
The notice and claim procedures under SC Code § 29-6-250 are critically important for subcontractors and suppliers seeking payment on bonded South Carolina public projects. The requirements differ depending on whether the claimant has a direct contract with the contractor:
- Claimants in privity with the contractor (those with a direct contract with the bonded contractor) are not required to serve a preliminary notice as a condition of making a claim on the payment bond.
- Claimants not in privity with the contractor (sub-subcontractors, second-tier suppliers, and others without a direct contract with the contractor) must serve a written notice on the contractor within 90 days after the claimant's final furnishing of labor or materials. This notice must state the amount claimed and identify the party for whom the work was performed or materials supplied.
- Method of service: The notice must be served by registered mail, certified mail (return receipt requested), or by hand delivery to the contractor.
Suit Deadline
Under SC Code § 29-6-250, no action may be brought on the payment bond after one year from the date on which the claimant last performed labor or furnished materials. This one-year statute of limitations is strictly enforced by South Carolina courts. A claimant who misses this deadline loses their right to recover on the bond, regardless of the merits of their claim. It is therefore essential for subcontractors and suppliers to track their last furnishing date carefully and to consult with legal counsel well before the deadline approaches.
Subdivision Bonds in South Carolina
Subdivision bonds (also called site improvement bonds or plat bonds) are required by South Carolina counties and municipalities when a land developer subdivides property and is responsible for constructing public improvements. These improvements typically include roads, sidewalks, curbing, storm drainage, water and sewer lines, street lighting, and landscaping within public rights-of-way.
In South Carolina, subdivision bond requirements are established at the local level by individual counties and municipalities through their land development ordinances and subdivision regulations. The bond guarantees that the developer will complete the required public improvements according to the approved site plans, engineering drawings, and applicable building codes. If the developer fails to complete the improvements, the local government can draw on the bond to hire another contractor to finish the work.
South Carolina's approach to land development is shaped by the South Carolina Local Government Comprehensive Planning Enabling Act (SC Code § 6-29-310 et seq.), which requires local governments to adopt comprehensive plans and land development regulations. Counties such as Charleston, Greenville, Richland, Horry, and Beaufort have detailed subdivision ordinances that specify bonding requirements for developers creating new residential and commercial subdivisions.
The bond amount is typically determined by the local government's engineer based on the estimated cost of the required improvements, and it often equals 100% to 120% of that estimate. Premiums for South Carolina subdivision bonds generally range from 1% to 3% of the bond amount, depending on the developer's financial condition, credit, and experience. South Carolina developers working in multiple jurisdictions should be aware that bond requirements and amounts can vary significantly from one county or municipality to another.
South Carolina Contractor Licensing
Construction contractor licensing in South Carolina is administered by two separate state agencies, depending on the type of work performed:
- SC Contractors' Licensing Board: Licenses general contractors, mechanical contractors, and specialty contractors who perform commercial, industrial, and public construction work. The Board operates under the SC Department of Labor, Licensing and Regulation (LLR). Contractors must pass an examination, demonstrate relevant experience, and meet financial responsibility requirements. There is no statewide license bond requirement for contractors licensed through this Board.
- SC Residential Builders Commission: Licenses residential builders and residential specialty contractors who perform work on residential properties (one- to four-family dwellings). The Commission requires a $15,000 contractor license bond as a condition of licensure. This bond protects consumers against financial loss resulting from a contractor's failure to comply with the SC Residential Builders Act. The bond must be issued by a surety authorized to do business in South Carolina.
South Carolina uses a classification system based on project value limits. General contractors are classified into tiers (Group 1 through Group 5 and Unlimited) based on the maximum value of a single project they are authorized to undertake. To qualify for higher tiers, contractors must demonstrate greater financial capacity, experience, and bonding ability. This classification system directly impacts a contractor's ability to bid on larger public projects.
The $15,000 residential builder's license bond is separate from contract surety bonds (bid, performance, and payment bonds). The license bond is a condition of holding a residential builder's license and remains in effect as long as the license is active. It provides a remedy for consumers who suffer financial loss due to the contractor's violation of the Residential Builders Act, including failure to complete work, substandard construction, or abandonment. The bond does not cover contract disputes on commercial or public projects.
Notice & Claim Requirements in South Carolina
Understanding South Carolina's notice and claim requirements is essential for subcontractors, laborers, and material suppliers working on bonded public construction projects. The procedures under SC Code § 29-6-250 are specific and strictly enforced, and failure to comply can result in the loss of payment bond rights. Below is a detailed breakdown of the key timelines and requirements.
| Requirement | Details |
|---|---|
| Payment bond threshold | Required on all public construction projects exceeding $50,000 under SC Code § 29-6-250. |
| Performance bond threshold | Required on public construction contracts exceeding $100,000 under SC Procurement Code § 11-35-3030. |
| Notice (claimants in privity) | Claimants who have a direct contract with the contractor are not required to serve a preliminary notice. |
| Notice (claimants not in privity) | Must serve written notice on the contractor within 90 days after the claimant's last furnishing of labor or materials. The notice must state the amount claimed and identify the party for whom the work was done. |
| Method of notice | Registered mail, certified mail (return receipt requested), or hand delivery to the contractor. |
| Suit deadline | No action on the payment bond may be brought after 1 year from the claimant's last furnishing of labor or materials. |
| Where to file suit | Actions must be brought in the appropriate state court in the county where the project is located. |
| Attorneys' fees | South Carolina courts may award reasonable attorneys' fees to the prevailing party in a payment bond action, depending on the circumstances and applicable contract provisions. |
These notice and claim provisions are distinct from the requirements under South Carolina's private mechanic's lien law (SC Code § 29-5). On private projects, subcontractors and suppliers must comply with the state's mechanic's lien filing requirements to secure their payment rights against the property. On public projects governed by § 29-6-250, the remedies run against the payment bond rather than the property, and the notice and filing procedures are different. Contractors, subcontractors, and suppliers should be careful not to confuse these two separate sets of requirements.
Frequently Asked Questions About South Carolina Contract Bonds
Under SC Code § 29-6-250 (the South Carolina Payment Bond Act), a payment bond is required on any public construction project in South Carolina that exceeds $50,000. The bond must be in an amount equal to the full contract price and is designed to protect subcontractors, laborers, and material suppliers who cannot file mechanic's liens against public property. For projects at or below $50,000, a payment bond may still be required as a matter of the governmental entity's policy.
Yes. Under the South Carolina Procurement Code (SC Code § 11-35-3030), performance bonds are required on public construction contracts exceeding $100,000. This is a statutory mandate, not merely discretionary. The performance bond must equal 100% of the contract price and guarantees that the contractor will complete the project in accordance with the contract documents. Most South Carolina state agencies, counties, and school districts follow this requirement.
Yes, for residential contractors. South Carolina requires a $15,000 contractor license bond for residential builders and residential specialty contractors through the SC Residential Builders Commission. This bond protects consumers against financial loss caused by a contractor's failure to comply with the Residential Builders Act. General and mechanical contractors licensed through the SC Contractors' Licensing Board (for commercial and industrial work) are not required to post a statewide license bond, although some local jurisdictions may have their own requirements.
The notice requirements depend on whether the claimant has a direct contract with the bonded contractor. Claimants who are in privity (have a direct contract with the contractor) are not required to serve a preliminary notice. Claimants who are not in privity (sub-subcontractors, second-tier suppliers, etc.) must serve a written notice on the contractor within 90 days after their final furnishing of labor or materials. The notice must state the amount claimed and identify the party for whom the work was performed. It must be served by registered or certified mail, or by hand delivery.
Under SC Code § 29-6-250, no action may be brought on a public project payment bond after one year from the date the claimant last performed labor or furnished materials. This statute of limitations is strictly enforced by South Carolina courts. Missing this deadline bars the claimant from recovering on the bond. Claimants should track their last furnishing date carefully and consult with an attorney well before the one-year deadline expires.
No. Mechanic's liens cannot be filed against public property in South Carolina. This is a fundamental principle of construction law that applies in all 50 states. On South Carolina public projects, the payment bond required under SC Code § 29-6-250 serves as the substitute for mechanic's lien rights. If you are a subcontractor or supplier who has not been paid on a South Carolina public project, your remedy is to make a claim against the contractor's payment bond rather than filing a lien.
South Carolina contract bond premiums typically range from 1% to 3% of the bond amount (which usually equals the contract price) for well-qualified contractors. The exact premium rate depends on several factors, including the contractor's personal and business credit scores, financial statements (balance sheet strength, working capital, net worth), years of construction experience, project size and type, and current work backlog. New contractors or those with credit challenges may pay higher rates. Bid bonds are always free through Surety Specialist. As an example, a South Carolina contractor bonding a $1,000,000 public project might pay $10,000 to $25,000 in combined performance and payment bond premiums.
