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.
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.
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.
Based on License Type and Anticipated Gross Volume
Contractor's Bond Requirements
| License Type | Exam Fee | License Fee | Renewal Fee |
|---|---|---|---|
| Residential Specialty (Less than $375k) Bond amount | — | $4,250 | |
| Residential Specialty ($375k or more) Bond amount | — | $7,500 | |
| Commercial Specialty ($150k or less) Bond amount | — | $2,500 | |
| Commercial Specialty ($150k - $500k) Bond amount | — | $7,000 | |
| Commercial Specialty ($500k - $1 million) Bond amount | — | $17,500 | |
| Commercial Specialty ($1 million - $5 million) Bond amount | — | $25,000 | |
| Commercial Specialty ($5 million - $10 million) Bond amount | — | $37,500 | |
| Commercial Specialty (Over $10 million) Bond amount | — | $50,000 |
Dual License Bond Calculation
To calculate the bond amount for the dual license, add the amount required for residential and commercial based on your anticipated gross volume.
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.
Important: Ongoing Bond Requirement
The contractor's bond is never-ending. Thus, you need to keep paying premiums to the insurance company as agreed. If you fail 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.
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.
