How to Get a Business License in Lake Charles: What You Need to Know (2026)
The Quick Version
Starting a business in Lake Charles, LA requires permits and registrations across multiple government layers — federal, state, Calcasieu Parish (county), and city. The primary city-level requirement is the Occupational License, issued by the Revenue 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.
Contact the Revenue Division at 337-491-1280 for current requirements. More information is available at cityoflakecharles.com.
