What this bond does
The Board defines this security as a performance bond guaranteeing full performance of the contractor's contract and protecting against breach. It is submitted for the plumbing and mechanical contractor license, but its customer-contract purpose should not be confused with a bond payable to the licensing agency.
- Who needs it
- A sole proprietor or legal entity contracting to provide plumbing or mechanical services covered by the Board's licensing requirements. Name the business that performs the work, not merely its individual master of record.
- Who it protects
- The Board accepts wording such as the licensee's Iowa customers or people injured by the principal's breach of construction contract. Its guidance requires the legal entity's bond to cover all plumbing or mechanical work performed by that entity. Confirm the accepted customer-benefit language on the proposed document.

The bond amount describes the limit of the bond obligation, not the price. A listed amount does not establish what the requesting party requires. The premium is what you pay and must be confirmed for the actual option. An E&O limit, where listed, is separate errors and omissions insurance.

Have these ready
- Identify the sole proprietor or legal entity performing the contracted work.
- Confirm the covered plumbing or mechanical disciplines and master of record.
- Match customer-benefit wording rather than naming the State or Board as the protected party.
- Verify at least $5,000 security and the Board's 10-day cancellation-notice provision.
- Keep Board license materials separate from any out-of-state registration bond filing.
Questions about this bond
Should the bond name the State of Iowa as the protected party?
The Board expressly says no: its guidance calls for the principal's customers, with accepted examples covering Iowa customers or people injured by breach of construction contract. The Board receives evidence and cancellation notice but is not the customer beneficiary.
Is this the $25,000 out-of-state contractor bond?
That is a separate DIAL registration requirement with its own form. The plumbing and mechanical contractor-license requirement is at least $5,000 for customer contract performance. Establish which filings the business needs rather than treating the two bonds as interchangeable.
