Full South Carolina licensing detail, local jurisdictions, and official sources
Licensing, bond, and insurance details
| Requirement | Detail | Source |
|---|---|---|
| Surety bond | Residential builders maintain a $15,000 license bond. A licensed residential plumber, electrician, or HVAC contractor files a $10,000 bond before offering or performing an undertaking above $5,000; a registered nonmechanical residential specialty contractor files a $5,000 bond above that amount. A commercial general or mechanical applicant may meet the applicable financial group through the required financial statement or an alternative continuous surety bond. Current mechanical bond amounts range from $7,000 in Group 1 to $300,000 in Group 5. | State source |
| General liability insurance | The statewide General and Mechanical Contractor application establishes financial capacity rather than one universal commercial general-liability minimum, and the ordinary residential plumbing application likewise centers on the statutory license bond, experience, exams, and financial review. Project owners, municipalities, contracts, and some classifications can require liability coverage. Workers-compensation coverage remains separate and mandatory when the employer is subject to the Act. | State source |

How to start a contracting business in South Carolina

What to verify before you bid
Before you bid in South Carolina, confirm the credential matches the exact work and that your business, tax, and insurance records use the same legal name. A state license or registration does not replace city or county permits, local business licensing, or bond requirements, so verify the job location too.
- Match the credential to the work. General building, residential work, electrical, plumbing, HVAC, roofing, public work, and specialty trades can follow different rules.
- Check the project location. A state registration never replaces city or county contractor registration, permits, bond requirements, or local business licensing.
- Set up the business first when required. Confirm the entity name, tax account, workers' compensation status, and insurance certificate match the name used on the license application and contracts.
- Confirm money and deadlines directly. Fees, financial limits, bonds, insurance minimums, renewal dates, notice rules, and lien deadlines are deliberately omitted unless they were checked against the responsible agency or statute.
