  1. Kansas City, KS — Plumbing Trade Licensing and Occupation Tax License

    Kansas has no statewide plumbing contractor license; the Kansas Department of Labor does not administer one, and dol.ks.gov/plumbing does not exist. In Kansas City, KS licensing is local: a plumbing contractor registers with the Unified Government's Business License Division for an occupation tax license, files a $5,000 plumber's surety bond (signed face sheet plus power of attorney) so permits can be pulled, and works with the Building Inspection division at 913-573-8620 on trade licensing and permits. Requirements differ in other Kansas cities and counties because plumbing licensing is local, not state-level.

    Official government source

    A $5,000 surety bond is mandatory (you pay the bond premium, not the face amount). The occupation tax is set by business classification in the Unified Government's ordinance — the Business License Division quotes it at 913-573-8780. Trade license and permit fees are set by Building Inspection.Not published as a fixed turnaround. Zoning approval comes first; building inspection can usually be scheduled the next business day after zoning approves. Confirm trade-licensing steps with Building Inspection at 913-573-8620.

  2. Unified Government of Wyandotte County / Kansas City, KS — Occupation Tax License

    Kansas City, KS requires every business to register. The Unified Government states that operating a business or performing a service in the city requires an occupation tax licence, issued by the Business License Division of the Neighborhood Resource Center at 4953 State Avenue (913-573-8780) — not the Finance Department. All businesses physically located in KCK must register annually and pay the occupation tax unless exempted by ordinance, and businesses based outside the city but working in it must register too. Zoning approval comes first: a Commercial Zoning Memorandum plus a Building Inspection zoning inspection for a commercial location, or a Home Occupied Zoning Memorandum for a home-based business. Some activities need an additional regulatory licence — alcohol, massage establishments and security companies are routed to the police department for background check and chief's approval, food and lodging go to the Kansas Department of Agriculture for health inspection, and daycares, restaurants with open grills or fryers, salvage yards and welding operations need fire inspection before opening.

    Official government source

    The occupation tax is set by business classification in the Unified Government's ordinance rather than by gross revenue tier; the Business License Division quotes the amount at 913-573-8780 and provides all forms free of charge, noting there is no need to pay a third-party filing service.Not published as a fixed turnaround. The Unified Government describes the process as quick and straightforward; zoning review is the first step, and a building inspection can usually be scheduled the next business day after zoning approval, with all utilities connected.

  3. Kansas City, KS — Plumbing Permit (per project)

    A separate plumbing permit must be pulled from the Unified Government's Building Inspection division (913-573-8620) for each job, with inspections on completion. Before any permit can be pulled, a plumbing contractor must be registered with the Business License Division for an occupation tax licence and must file a $5,000 plumber's surety bond — the signed face sheet plus the power of attorney page go to the Business License Division, and Building Inspection will not issue permits without it. The same $5,000 bond requirement applies to electrical, mechanical/HVAC, hauling, septic tank and sign hanging contractors. Kansas has no statewide plumbing licence, so this local credential is the operative one.

    Official government source

    The Unified Government does not publish a flat plumbing permit fee; charges are quoted by Building Inspection at 913-573-8620 and depend on the work. Budget separately for the $5,000 bond premium and the annual occupation tax.Not published as a fixed turnaround. Get the bond and occupation tax licence in place first — that is the step that gates permit issuance, not the permit itself.
