Most likely yes. Addition or structural alteration usually requires a permit in Iowa. Confirm the specifics with Unincorporated Carroll County.
The state building code reaches a private home only where the city or county has adopted it, or in a city of more than 15,000 people with no comparable local code (Iowa Code 103A.10); the first question is which office, if any, issues building permits for the address. The statewide residential energy code covers construction of heated or cooled space throughout Iowa, with an exception only for remodeling or renovation of one- and two-family dwellings (481 IAC 301.23(2) and 301.24). Electrical permits come from the local electrical inspection program where one exists and from the DIAL state electrical inspection program everywhere else (Iowa Code 103.24; 481 IAC 404.5(1)). Contractors who earn $2,000 or more a year from construction must register with DIAL, and a permit may not be issued to a contractor who is required to register and has not (Iowa Code 91C.1 and 103A.20).
