What permits do you need to open a contractor or trade in Jackson County Mo?

Commercial Mechanical Repair Permit

The Unincorporated Jackson County Building Permits packet, dated January 2025, lists the Commercial fee for a Mechanical Repair permit at $125. The Residential column of the same table lists $75 and is not used. Chapter 54 section 5411 requires that mechanical work under a county permit be performed by a person holding the appropriate license, and the packet's Commercial Building Permit Procedures require mechanical diagrams with the application. A licensed mechanical contractor pulls this permit for the work, and the trade license is recorded separately.

Commercial Plumbing or Gas Repair Permit

The Unincorporated Jackson County Building Permits packet, dated January 2025, lists the Commercial fee for a Plumbing/Gas Repair permit at $150. The Residential column of the same table lists $75 and is not used. Chapter 54 section 5411 requires that plumbing work under a county permit be performed by a person holding the appropriate license, or by a person working under the direct supervision of a licensed holder. The fee is set in the packet's Permit Fees table, which is a county publication and is the figure recorded here.

Commercial Raze Permit

The Unincorporated Jackson County Building Permits packet, dated January 2025, lists the Commercial fee for a Raze permit at $150. The Residential column of the same table lists $50 and is not used. The packet requires a site plan that shows the structure to be razed and states that a pumping receipt must be provided at the final inspection once the raze is complete. A raze permit applies to demolition of a structure, and it is separate from the commercial building permit that may follow it.

Soil and Erosion Control Permit

The Unincorporated Jackson County Building Permits packet, dated January 2025, states the Soil & Erosion Control fee as '$500.00 + $100.00/acre of disturbed land,' and its text reads '$500.00 plus $100.00 per acre of disturbed land.' The packet cites Jackson County Code Chapter 241 (Sediment and Erosion) and requires an erosion and sediment control plan with commercial applications. The fee applies to land-disturbing activity for commercial building work in the unincorporated county.

Electrical, Mechanical and Plumbing Trade License (Classes A, B and C)

Chapter 54 section 5411 requires the appropriate electrical, mechanical or plumbing license for work under a county permit, except owner-occupant work with an affidavit. Section 5411.4(b) sets a one-time non-refundable application fee of $25. Section 5411.4(c) sets the license fee for each class: Type A $175, Type B $175 and Type C $45. Section 5411.5(a) states that a Type A or Type B license is renewed on payment of the license fee in section 5411.4 and a showing of eight continuing education units since issuance or the last renewal, so the renewal fee for those classes is the $175 license fee. Section 5411.5(b) limits Type C licenses to one year. The license applies to contractors who perform electrical, mechanical or plumbing work under a county permit in the unincorporated county.

Statewide Electrical Contractor License (optional)

This license exists to solve one specific problem and nothing more: a contractor working across several Missouri jurisdictions no longer needs a separate local electrical license in each one, because state law obliges every city and county to recognise this statewide credential in place of its own. It does not abolish local licensing — a city may keep issuing its own electrical contractor license to everyone else, keep requiring a business license, keep issuing permits and inspecting work, and keep licensing individual electricians on its own examination, all in parallel with this statewide option. The state gives that recognition rule real teeth: a political subdivision that refuses to honour a statewide license risks having its own share of state sales tax withheld until it complies. Two hundred dollars to obtain it and $100 to renew, on a shared three-year cycle rather than one tied to the individual holder.

General Contractor License — Missouri state position (local licensing)

The Division of Professional Registration's own list of every board it administers includes Electrical Contractors but has no general contractor, plumbing or HVAC board, so there is no state fee for any of those three licenses. Plumbing licensing is confined by statute to cities of 15,000 people or more and to first-class counties, each running its own board of examiners and its own local code, and HVAC work is regulated only where a city chooses to license it. A contractor working across several Missouri municipalities may need a separate local license in each one for these trades. Electrical work is the exception — see the statewide electrical contractor record.
