12What catches people out in Nevada What is this?
The things people get wrong or do not expect about Nevada, in a few sentences.
- Nevada lets unlicensed people do repair jobs under $1,000, but the law names plumbing as work that exception never covers. Even a small leak repair for pay needs a licensed contractor.
- There is no license called just plumbing. The full license is C-1 Plumbing and Heating, and plumbing alone is the C-1d piece of it. Water heaters and gas piping have their own smaller pieces.
- Your plumbing license comes with a dollar ceiling called a monetary limit. You cannot sign a job above it, and the limit must be printed next to your license number on every bid and contract.
- Nobody can tell you your bond amount up front. The board picks a figure between $1,000 and $500,000 for each plumbing license after it reads your financial statement.
- You pay sales tax on pipe and fixtures at the supply house and charge your customer none. Nevada sees a plumbing contractor as the final user of the materials, on repairs and on new homes alike.
