South Carolina Contractor License Bonds5 Groups, $20,000 to $500,000

South Carolina uses a group-based system where the bond amount corresponds to your license group level, which determines your maximum bid and job limits. General contractors have 5 groups with bonds from $20,000 (Group 1) to $500,000 (Group 5). Mechanical contractors also have 5 groups with bonds from $7,000 to $400,000. The bond serves as an alternative to demonstrating net worth -- you can post a bond equal to the net worth requirement for your group instead of providing financial statements showing that net worth.

The 2023 legislative update, effective July 2023, made significant changes to bond-to-net-worth ratios. Previously, the bond amount was set at twice the net worth requirement. The reforms reduced this to a 1:1 ratio -- the bond now equals the net worth amount for each group. All licensees were required to meet the updated financial or bond requirements at their next renewal cycle in 2024. The reforms also updated bid and job limitations by group.

General contractors handle overall construction management for residential and commercial projects, with Group 5 allowing unlimited project values. Mechanical contractors specialize in HVAC, plumbing, electrical, and fire protection systems. Each type has its own 5-group system with different net worth thresholds, bond amounts, and bid limits. Mechanical contractor bond amounts are lower, ranging from $7,000 to $400,000 compared to $20,000 to $500,000 for general contractors.

Residential builders are licensed separately through the SC Residential Builders Commission (also under LLR) and must maintain a $15,000 surety bond at all times. Residential specialty contractors require bonds of $5,000 to $10,000 depending on their classification. These are separate licensing tracks from the Contractors Licensing Board that governs general and mechanical contractors.

Costs depend on the bond amount and your credit profile. Group 1 general contractor bonds ($20,000) cost $200-$600/year with good credit. Group 3 bonds ($200,000) cost $2,000-$6,000/year. Group 5 bonds ($500,000) cost $5,000-$15,000/year. Contractors with excellent credit (750+) typically pay 1-2% of the bond amount. Credit-challenged applicants pay 5-15% through specialized programs.

Yes. South Carolina allows contractors to post a surety bond as an alternative to demonstrating the required net worth for their license group. After the 2023 reforms, the bond amount equals the net worth requirement (previously it was double). This means a Group 3 general contractor can either show $100,000 net worth on CPA-compiled financial statements or post a $200,000 surety bond. Many contractors find the bond more cost-effective than tying up capital. For details on how bond premiums are calculated, see our surety bond cost guide at /surety-bond-cost/.

The South Carolina Department of Labor, Licensing and Regulation (LLR) oversees contractor licensing through two boards: the Contractors Licensing Board (for general and mechanical contractors) and the Residential Builders Commission (for residential builders and specialty contractors). LLR administers exams, investigates complaints, enforces regulations, and disciplines licensees. Contact: (803) 896-4696.

We issue South Carolina contractor bonds within 24-48 hours for most applicants. The application requires business information, license group designation, personal credit authorization, and financial details. Bonds are delivered electronically for immediate filing with SC LLR. The LLR license application itself typically processes in 4-6 weeks after all documentation is received.

No. A contractor bond and insurance protect different parties. The surety bond protects SC consumers and the state -- if a claim is paid, the contractor must reimburse the surety company. Insurance protects the contractor from their own losses. South Carolina requires both: a surety bond as an alternative to net worth (or mandatory for residential builders), plus general liability and workers compensation insurance.

To advance to a higher group, you must either demonstrate increased net worth through financial statements (owner-prepared for Groups 1-2, CPA compiled for Group 3, CPA audited for Groups 4-5) or increase your surety bond to match the higher group amount. For example, moving from Group 1 ($20,000 bond) to Group 3 ($200,000 bond) increases your bid limit from $40,000 to $400,000. Contact SC LLR at (803) 896-4696 to initiate a group upgrade.
