Continuing education is not mandated by Iowa for home improvement contractors; however, staying current on building codes, safety regulations, and industry practices is recommended. To renew, submit your renewal application online through the state portal at https://www.iowaattorneygeneral.gov or mail it to the Consumer Protection Division. If you fail to renew by the expiration date, your license becomes inactive; you cannot legally perform home improvement contracts until renewal is completed.

Operating as a bathroom remodeler in Iowa without a valid Home Improvement Contractor license is a violation of Iowa Code § 18.6 and constitutes engaging in an unlicensed trade. Civil penalties include fines up to $5,000 per violation, plus potential restitution to injured homeowners (Iowa Code § 18.6). The Iowa Attorney General can issue a cease-and-desist order, requiring immediate cessation of unlicensed work.

Criminal penalties apply for repeat violations or fraud; unlicensed home improvement contracting can result in Class B misdemeanor charges (punishable by up to 30 days in jail and fines up to $625) or Class D felony charges for aggravated violations (30 days to one year imprisonment and fines up to $5,000) under Iowa Code § 18.6(4). Des Moines city inspectors and the Attorney General's Consumer Protection Division actively enforce licensing requirements by conducting site inspections and responding to consumer complaints.

Violations are discovered through consumer complaints, city building permit audits, and AG office investigations. Insurance companies will deny coverage for unlicensed work, leaving you liable for all damages, injuries, and defects. Homeowners can file complaints with the Iowa Attorney General's office, triggering investigations that may result in project stop-work orders, fines, and mandatory corrective action. Unlicensed operation also exposes you to personal liability lawsuits from homeowners for defective work.
