Does plumbing work in Kansas City need a permit?
Kansas City requires permits before beginning most plumbing work. Minor jobs like replacing a faucet or other fixture can be exempt, but most other projects need a permit. Work is generally inspected at several phases before final approval.
Can a homeowner pull their own plumbing permit?
A single-family homeowner may obtain plumbing permits only if they occupy the dwelling and do the work themselves. Anyone else requesting plumbing permits must be a licensed contractor, not just an unlicensed handyman. Ask your pro which route applies to your job.
How do Kansas City plumbing contractors get licensed?
Kansas City contractor licensing requires a business license, a Certificate of Qualification for the trade, and then a contractor license for the business. The contractor license application carries a $60 nonrefundable fee. Master plumber applicants must be at least 25 with 3 or more years as a licensed journeyman plumber under Missouri law.
What should I ask for before work starts?
Ask the pro for a current insurance certificate and proof of the required $500 minimum cash deposit. Confirm who pulls the permit and that permit fees are paid, since a permit is not valid until fees are paid. Request a written quote that lists the work and any permit or excavation fees.
What to do next
