In Iowa, most “handyman/general repair” work is not covered by a single statewide general-contractor license, but you can still be regulated through (1) state contractor registration for construction contracting, (2) required state trade licenses for electrical/plumbing/HVAC, and (3) local (city/county) permits and registrations. For Onawa (Monona County), expect to register as a contractor with the Iowa Division of Labor if you perform construction work, and pull city building permits for work that triggers permits; electrical/plumbing/HVAC work generally requires a licensed trade contractor/technician.
