Intercom System Permit Requirements in Mississippi

Mississippi has a unique regulatory structure where electrician licenses are issued at the local level while contractor licensing for larger commercial projects goes through the State Board of Contractors. Here's what contractors need to know about intercom installation in Mississippi.

State Licensing Overview

Mississippi's electrical licensing structure is decentralized:

Local Electrician Licenses

All Mississippi electrician licenses are issued at the local level through your city or county. This means:

• Requirements vary by jurisdiction
• Each city/county sets its own licensing standards
• No statewide electrician license exists
• Low voltage work may or may not require local licensing

State Board of Contractors (MSBOC)

The Mississippi State Board of Contractors licenses contractors for larger commercial projects:

• Required for commercial jobs over $50,000

Mississippi has reciprocal agreements with neighboring states:
