Safety, Codes, and Regulatory Compliance
OSHA fundamentals
Federal OSHA covers construction in South Carolina - there is no state-plan enforcement authority, so 29 CFR 1926 applies. Know the Focus Four hazards: falls, struck-by, caught-in/between, and electrical. Key thresholds: fall protection at 6 ft in construction; guardrails, safety nets, or personal fall arrest systems; excavations 5 ft deep need protection; ladders in trenches every 25 ft of lateral travel; scaffolds require fall protection above 10 ft; crane and rigging inspections; hazard communication and silica exposure controls.
Codes and permitting
South Carolina adopts the International Codes through the state Building Codes Council, with local amendments and local enforcement. Know the permit and inspection sequence: permit application, plan review, footing/foundation, framing, rough-in, insulation, and final. Know when a certificate of occupancy is required, how variances and floodplain requirements work, and why work outside the permitted scope creates liability. Environmental compliance runs through state agency permits for stormwater, wetlands, and air quality, plus EPA rules for lead-safe renovation and asbestos.
Licensing and business regulation
Contractor licensing, specialty classification, and continuing education flow from state statute and the licensing board; operating outside your license classification is a compliance violation regardless of competence.
Traps
- Assuming South Carolina runs its own OSHA plan - it does not.
- Applying the 6 ft fall rule to scaffolds (the trigger differs) or to steel erection.
- Believing a building permit covers environmental permits - they are separate.
- Missing that the competent person must actually inspect and document.
Rule of thumb
When a safety question gives a dimension, the answer is almost always tied to a threshold number: 4 ft (guardrail height), 5 ft (excavation), 6 ft (fall protection), 10 ft (scaffold), 25 ft (trench ladder spacing).
