Types of Plumbing Licenses in Arizona

In Arizona, plumbers are classified as per their specialties. Here are the three common types of plumbing licenses:

  • Specialty Commercial Plumbing (C-37): This is the commercial plumbing license for contractors providing plumbing services in commercial estates and regions.
  • Specialty Residential Plumbing (R-37R): This is the residential plumbing license for contractors providing plumbing services in residential estates and regions.
  • Specialty Dual CR-37 Plumbing (CR-37): This is the dual plumbing license for contractors providing plumbing services in both kinds of estates and regions – commercial and residential.

We know that you may be wondering about the Recovery Fund Assessment. So let us show you the fund and bond involved in becoming a licensed plumbing contractor in Arizona.

The Bond and The Fund You Need to Take Care of

Unfortunately, the various costs shown above aren’t the only costs you need to bear to get your license. In Arizona, property owners and the state are protected from any kind of illegal activities or damage done by contractors (including plumbers).

Thus, you will need to file for one or both of these, depending on the type of license you need. Take a closer look at both of these:

1. Contractor’s bond

Contractor’s bond or license bond is mandatory for all types of contractors in Arizona. In other words, you cannot go past it.

Contractor’s bond

The amount for the bond is determined by the type of plumbing license you want and the anticipated annual gross volume of the amount of contract you will get. Check out the official figures for the bond amount you will need to pay.

Type of license Anticipated gross volume Bond amount
Residential Specialty Contractors
  • Less than $375k
  • $375k or more
  • $4,250
  • $7,500
Commercial Specialty Contractors
  • $150k or less
  • $150k – $500k
  • $500k – $1 million
  • $1 million – $5 million
  • $5 million – $10 million
  • Over $10 million
  • $2,500
  • $7,000
  • $17,500
  • $25,000
  • $37,500
  • $50,000

To calculate the bond amount for the dual license, add the amount required for residential and commercial.

This bond can be in the form of a surety bond, cash bond, or certificate of deposit. You can get a certificate of deposit from any bank that operates in Arizona.

If you want to obtain a surety bond, here is the list of businesses licensed to offer surety products in Arizona by the Arizona Department of Insurance.

The contractor’s bond is never-ending. Thus, you need to keep paying premiums to the insurance company as agreed. If you failed to do so, your license will be suspended.

2. Recovery fund

If you want to provide plumbing services to the residential arena, you need to take care of this as well. Whether you are looking for a specialty residential or dual license.

Recovery fund

Arizona requires all licensed residential contractors to provide additional financial protection of $200k to their clients. There are two ways you can do this: –

Post a second bond (surety or cash) of $200k.
Pay into the Recovery Fund.

Most of the residential contractors go with the Recovery Fund.
