Plumbing company License Requirements in Des Moines, IA

Federal requirements for plumbing companies include obtaining an Employer Identification Number (EIN) from the Internal Revenue Service (26 U.S.C. § 6011) if you plan to hire employees.

The Environmental Protection Agency (EPA) enforces water quality standards relevant to plumbing work, particularly regarding lead-free soldering materials under the Lead and Copper Rule (42 U.S.C. § 300j-4). If your company handles refrigerants or air conditioning components, EPA certification under the Clean Air Act (42 U.S.C. § 7671) may be required.

Americans with Disabilities Act (ADA) compliance (42 U.S.C. § 12101 et seq.) applies if you have a physical business location open to customers, requiring accessible facilities and restrooms. Workers' compensation insurance is not federally mandated but is required by Iowa law for companies with employees. If you transport hazardous materials as part of plumbing work, Department of Transportation (DOT) regulations may apply (49 U.S.C. § 5101 et seq.).

Des Moines requires plumbing companies to obtain a Plumbing Permit from the Des Moines Building Services Department before commencing any plumbing work (Des Moines Municipal Code Chapter 26). The city requires a separate permit for each plumbing project, including new installations, repairs, replacements, and alterations to plumbing systems.

All plumbing work must be inspected by the city to ensure compliance with the International Plumbing Code and Des Moines Municipal Code. Inspections occur at rough-in stage (after pipes are installed but before walls are closed) and final inspection (after work completion). You must request inspections through the Des Moines Building Services Department, either online at https://www.dmgov.org or in person at 602 Robert D. Ray Drive.

Des Moines also requires contractor registration if your company has employees or operates as a business entity. The city does not typically restrict plumbing work by zoning but requires compliance with building codes and setback requirements for outdoor installations.

Iowa plumbing licenses renew annually on December 31, regardless of when the license was originally issued (Iowa Code Chapter 105). Renewal applications must be submitted to the Department of Workforce Development before the expiration date. The renewal fee ranges from $50-$100 depending on license classification.

Continuing education requirements vary by license type. Master Plumbers and Journeyman Plumbers must complete 12 clock hours of approved continuing education per renewal period, with at least 4 hours covering code updates and safety. Apprentice Plumbers are not required to complete continuing education but must remain enrolled in an active apprenticeship program. Approved continuing education includes courses offered by the Iowa Association of Plumbers, community colleges, and accredited trade organizations.

Renewal can be completed online through the Iowa Department of Workforce Development portal or by mail. If you miss the December 31 deadline, your license becomes inactive, and you cannot legally perform plumbing work. You may reinstate an expired license within one year by paying a late renewal fee (typically an additional $25-$50) plus the standard renewal fee. If your license has been expired for more than one year, you must reapply and retake the examination.

Operating as a plumber in Iowa without a valid state license is a violation of Iowa Code Chapter 105 and constitutes illegal practice of plumbing.

The Iowa Department of Workforce Development's Plumbing and Mechanical Systems Board has authority to issue cease-and-desist orders prohibiting unlicensed individuals from performing plumbing work (Iowa Code § 105.8).

Criminal penalties apply in cases of repeated violations or fraudulent misrepresentation of licensure. Operating without a license can result in a simple misdemeanor charge (Iowa Code § 105.8), carrying fines up to $625 and potential jail time up to 30 days.

Insurance complications arise from unlicensed operation; homeowners' and commercial property insurance policies typically include exclusions for work performed by unlicensed contractors. If damage occurs (burst pipes, water damage, improper installation), the insurance company may deny claims when the work was performed by unlicensed personnel. Des Moines Building Services Department inspectors verify licensure during inspections; failure to provide valid license documentation can result in permit revocation and project shutdown.
