South Carolina: up to $500 a job without a contractor license

The limit in South Carolina

The limit: Up to $500 per job (homes). In short: residential trade work up to $500 per undertaking needs no registration; above $500 you need a residential specialty registration (or a license for plumbing, electrical, HVAC); above $5,000 a residential builder license.

What counts: Residential specialty contractor: work "when the undertakings exceed five hundred dollars"; residential builder: "when the cost of the undertaking exceeds five thousand dollars." The statute does not say whether materials count toward the $500. The state's words do not say whether materials count toward the limit.

Conditions: residential work only (commercial uses the $10,000 Chapter 11 threshold); a specialty registrant is limited to three trade classifications and cannot build additions without a residential builder.

Plumbers, electricians and heating/air-conditioning installers must hold a specialty LICENSE (by exam) above $500; other trades (carpentry, drywall, painting, masonry, roofing, etc.) get a registration.
