How to Get a Business License in Mckinney: What You Need to Know (2026)
The Quick Version
Starting a business in Mckinney, TX requires permits and registrations across multiple government layers — federal, state, Collin County (county), and city. The primary city-level requirement is the Certificate of Occupancy, issued by the Building Inspections. 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 Building Inspections at 972-547-7580 for current requirements. More information is available at mckinneytexas.org.

How Long Does It Take?
Most businesses in Mckinney can be fully licensed and operational within 4 to 12 weeks, depending on the business type. Simple home-based businesses can often complete the process in 2 to 4 weeks, while restaurants, bars, and businesses requiring inspections typically take 8 to 12 weeks.
The dependency chain matters — some permits can't be applied for until others are in place. Getting the order wrong means delays and wasted time.
