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 Plumbing Permit (per project)

   A separate plumbing permit must be pulled from the City of Overland Park for each job, 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 'DP' Plumbing Contractor License, which entitles the holder to perform plumbing services only. Kansas has no statewide plumbing licence, so the county licence is the operative credential.
