the short answer

every Nevada plumbing class.

C‑1 and the plumbing subclasses under it, in plain words.

C‑1: Plumbing and heating, the full specialty. A C‑1 holder can do any work its subclasses allow.
C‑1d: Plumbing. Water supply, waste and vent systems, roof drainage, small hydronic heating, landscape irrigation, water heating including solar, a permanent gas supply, and medical gas and compressed air piping. Plus water and gas piping from the building to the meter.
C‑1g: Gas. Pipes and vents from the source of supply of liquefied petroleum and natural gas.
C‑1h: Water heaters. Installing, replacing and repairing them.
Monetary limit: Set by the Board on every license. It’s the largest contract you can take on one site or subdivision for one client, and you can apply to raise it with proof of financial responsibility.

Straight answers on Nevada plumbing license classes.

What plumbing license do I need in Nevada?

Nevada licenses plumbing contractors under the State Contractors Board’s C-1 plumbing and heating classification. Most plumbing shops hold the C-1d plumbing subclass, which covers water supply, waste and vent, roof drainage, water heating and a permanent gas supply. Some also hold C-1g for gas or C-1h for water heaters. The Board decides which class fits your work.

What’s the difference between C-1 and C-1d in Nevada?

C-1 is the full plumbing and heating classification, and a C-1 holder can do any work its subclasses allow, from boilers and fire sprinklers to air conditioning. C-1d is the plumbing subclass: water supply, waste and vent, roof drainage, water heating, gas supply, medical gas and the piping from the building to the meter.

What is the monetary limit on a Nevada contractor license?

It’s the largest contract you can take on one site or subdivision for one client. The Board sets one on every license after weighing your experience and finances, and you can ask it to raise the limit, permanently or for a single project. The limit doesn’t change what insurance you must carry, but GCs notice it.
