1. Johnson County Contractor Licensing — Class DM Mechanical (HVAC) Contractor License

   Kansas has no statewide HVAC or mechanical contractor license; the Kansas Department of Labor administers none. For work in Overland Park, HVAC contractors must hold a Johnson County Class DM Mechanical Contractor License, which entitles the holder to perform HVAC, mechanical, and refrigeration services only. Johnson County Contractor Licensing, a division of Planning, Housing and Community Development, issues 11 construction contractor license types through its Contractor Licensing System portal. EPA Section 608 certification remains separately required under federal law for refrigerant handling.

2. City of Overland Park - No General Business License (Specialty Licenses Only)

   Overland Park does not require a general business license or Certificate of Occupancy renewal for most businesses. The City Clerk's office administers a small set of specialty licenses (massage therapist/establishment, pawnbroker, precious metal dealer, taxi/limo/car service, transient merchant) for businesses that fall into those categories; a Certificate of Occupancy is a one-time requirement tied to the space, not an annual business license.

3. Overland Park Mechanical Permit (per project)

   A mechanical permit must be obtained from the City of Overland Park for each HVAC installation or major repair, with inspections on completion. Overland Park administers building, electrical, plumbing and mechanical permits and inspections directly — Johnson County has no permitting jurisdiction inside city limits. The permit can only be pulled by a company holding a Johnson County Class 'DM' Mechanical Contractor License, which entitles the holder to perform HVAC, mechanical and refrigeration services only. Kansas has no statewide HVAC licence, so the county licence is the operative credential; technicians handling refrigerants separately need federal EPA Section 608 certification.
