Who Is Liable for Construction Defects in South Carolina: Builder, Developer, or Subcontractor?

South Carolina construction defect claims can extend to the general contractor, subcontractors, the property developer, design professionals, and material suppliers, depending on where the defect originated. Identifying which parties may share responsibility may identify additional insurance coverage that could apply. In certain residential construction defect actions, South Carolina's Notice and Opportunity to Cure Construction Dwelling Defects Act generally requires applicable pre-suit notice to contractors or subcontractors that the claimant intends to pursue.

When a homeowner or a homeowners' association discovers a construction defect, the first question is almost always the same: who do we go after? A cracked foundation, a leaking roof, or failing stucco rarely has one obvious culprit. South Carolina construction defect law may permit claims against multiple parties, and figuring out which ones may responsibility can affect the available claims and potential sources of recovery.

At Derrick Law Firm Injury Lawyers, our attorneys can assist clients with potential construction defect claims by evaluating the available evidence to investigate a defect and its potential source, whether that source is a general contractor's decision, a subcontractor's installation, a supplier's defective material, or a design professional's plans. This evaluation is important as South Carolina law treats each of these parties differently.

What Role Does the General Contractor Play?

The general contractor, sometimes called the builder, typically oversees the entire project and is often the first party a claimant looks to. A general contractor may be liable for its own negligent supervision or other duties it assumed, but South Carolina does not automatically make a general contractor liable for an independent subcontractor’s negligence.

That does not mean every defect traces back to the general contractor's own hands. A contractor who properly selected and reasonably supervised a subcontractor may still face a claim, but responsibility for the particular defect may rest in whole or in part with the subcontractor who performed the specific work.

When Is a Subcontractor Responsible Instead of the General Contractor?

Modern residential construction typically involves separate subcontractors for framing, roofing, plumbing, electrical work, waterproofing, and other specialized trades. When a defect traces to one of these specific systems, such as a roof that leaks because of improper flashing, the subcontractor who installed that system may bear direct responsibility.

Common areas where subcontractor responsibility may arise include:

• Roofing and waterproofing failures traced to improper installation rather than a design flaw
• Plumbing or electrical defects that violate applicable codes in effect at the time of construction
• Foundation or framing work that deviates from the approved plans and specifications
• HVAC or mechanical systems installed incorrectly, even when the equipment itself was not defective

Can a Property Developer Be Held Liable Separately From the Builder?

Potentially, yes. In many South Carolina projects, particularly multi-home developments, the developer and the general contractor are related but legally distinct. A developer who oversaw site planning, made design decisions, or controlled the overall quality of construction across a project may share liability for a construction defect even when a separate general contractor handled the day-to-day building. This distinction may be particularly important in cases involving a construction defect repeated across an entire development, where the developer's decisions at the planning stage may have introduced the same flaw into every home. 

When Do Design Professionals Share Responsibility?

Architects and engineers are responsible for the plans and specifications that a project is built from. When a construction defect stems from a design error, such as a structural miscalculation or a drainage plan that was inadequate as drawn, the design professional may share liability depending on the facts. Attorney Jamie Williams, a Derrick Law Firm construction defect lawyer, regularly works through this distinction when a defect could plausibly trace back to either the design or the construction of a project.

Determining whether a defect is a design problem or a construction problem is not always obvious from the outside. A wall that cracks could reflect a foundation that was improperly poured, or it could reflect a foundation that was poured exactly as designed, with the design itself being the problem. This is one of the reasons early expert evaluation may help identify potentially responsible parties.

What About Material Suppliers and Manufacturers?

When a construction defect results from a defective building product, such as a failed waterproofing membrane, defective siding, or a fastener that does not meet its stated specifications, the manufacturer or supplier of that material may face a separate product liability claim. These claims may proceed alongside claims against the installer who installed the product, since installation error and product defect are different legal theories that can both apply to the same damaged wall or roof.

How Does South Carolina's Right to Cure Law Affect Who You Can Sue?

Before filing suit against a contractor or subcontractor over a residential construction defect, South Carolina law generally requires written notice at least ninety days in advance. Under the South Carolina Notice and Opportunity to Cure Construction Dwelling Defects Act, the contractor or subcontractor has an opportunity to inspect the property and generally has thirty days after service of the notice to provide a written response offering to remedy the defect, offering to settle the claim, or denying the claim. This process should be considered with respect to each contractor or subcontractor a claimant intends to name, so identifying potentially responsible parties early affects how the pre-litigation notice needs to be structured. 

How Can You Confirm Whether a Contractor Was Properly Licensed?

South Carolina requires most residential builders and specialty contractors to hold a current license or registration through the appropriate board within the South Carolina Department of Labor, Licensing and Regulation, including the Residential Builders Commission for qualifying residential work. An unlicensed contractor who was required to be licensed may face additional consequences beyond the underlying construction defect claim, and license status can affect the legal and regulatory issues in the case. Checking licensing status early is a simple step that can reveal important information about who actually performed the work on a project.

Why Does It Matter Which Parties You Name?

Identifying potentially responsible parties may also identify potential insurance coverage that could apply to the claim. Depending on the parties involved, potential sources of coverage could include:

• The general contractor's commercial general liability policy
• A subcontractor's separate liability coverage for its specific trade
• A material supplier's or manufacturer's product liability coverage
• A design professional's professional liability, or errors and omissions, policy

When multiple parties may have contributed to a defect, identifying the potentially responsible parties can be important to evaluating the available claims and insurance coverage. Attorney Jamie Williams built years of his career representing businesses and their insurers in construction defect litigation before joining Derrick Law Firm Injury Lawyers, and that background now informs how our construction defect attorneys evaluate which parties, and which policies, belong in a claim from the outset.

When a construction defect also causes a physical injury, such as a structural collapse on a property, the personal injury claim and the construction defect claim may proceed under different rules, and the Notice and Opportunity to Cure Construction Dwelling Defects Act's pre-suit notice requirements generally apply to claims for injury or loss to a dwelling or property, and not the personal injury or death claims.
