Why it matters
When no permit is required, no city inspector checks the installation. The contractor’s own process and workmanship warranty carry more of the weight, and a county license shows only that the company met the county’s insurance and qualification requirements for the class it holds.
What this number can’t tell you
- Each Johnson County city decides which work needs a permit; check your city before work starts.
- A license class held for general or roofing work does not certify siding installation.
- A missing county match is a research limit, not a finding that a company is unlicensed for the work it does.
What to do with it
- Ask whether your job needs a permit in your city, and who will pull it if the work touches sheathing, windows or the roof.
- Ask for the contractor’s county license number and a current certificate of insurance.
- Get the workmanship-warranty term in writing, since an inspection may never happen.
