How to Get a Business License in Mount Pleasant: What You Need to Know (2026)
The Quick Version
Starting a business in Mount Pleasant, SC requires permits and registrations across multiple government layers — federal, state, Charleston County (county), and city. The primary city-level requirement is the Business License, issued by the Business License Division. Most businesses need 5 to 10 separate registrations, and the order you complete them matters because each step has dependencies on the ones before it.
