Do you need a state license in Iowa?
Iowa licenses some general contractor work at the state level and leaves the rest alone. Which side of that line a job falls on decides whether you need the state license.
No registration needed if you earn less than $2,000 a year from construction, or only work on your own property.
DIAL says to contact the city or county for each project to learn local requirements.
