In Iowa, there is no statewide “general contractor license” for most residential/commercial handyman-style work, but you may need a state contractor registration if you perform construction work and meet certain payroll/employee conditions (and you must comply with Iowa sales tax/withholding rules). Separate state licenses are required for regulated trades like electrical and plumbing; most handyman work is legal without a state license as long as you avoid trade-restricted work and you still pull required building permits through the City/County.
