Iowa Sheet Metal Contractor License
The Iowa Plumbing and Mechanical Systems Board (PMSB) issues the Sheet Metal Contractor license to businesses that provide sheet metal fabrication and installation services on a contractual basis. The sheet metal discipline covers ductwork, ventilation systems, and architectural sheet metal work.
What This License Authorizes
A Sheet Metal Contractor license authorizes the holder to contract for and perform fabrication, installation, alteration, and repair of sheet metal systems throughout Iowa. This includes HVAC ductwork, exhaust systems, and related sheet metal construction. The contractor must have a master of record with an active Master Sheet Metal license.
Bond and Insurance Requirements
- Surety Bond: $5,000 minimum performance bond required, filed with the PMSB
- General Liability Insurance: Minimum $500,000 coverage from an Iowa-licensed insurer
- Workers' Compensation: Required if the contractor has employees
Application Process
The combined contractor license and registration fee is $380 for a full three-year term. Paper applications incur an additional $25 processing fee. Applicants must demonstrate they hold or employ someone with an active Master Sheet Metal license and provide proof of insurance and bonding. Allow four to six weeks for processing.
Renewal Process
- Renewal Period: Every 3 years (next expiration: June 30, 2029)
- Renewal Fee: $380 (combined license and registration)
- Continuing Education: 8 hours of classroom instruction required per three-year licensing term
- Grace Period: Approximately 30 days after expiration to renew without additional penalties
Consequences of Operating Without a License
Operating as an unlicensed sheet metal contractor violates Iowa Code Chapter 105. The PMSB may issue cease-and-desist orders, impose administrative penalties, and initiate license revocation proceedings against violators.
