Marshalltown has three commercial districts and a industrial district:
- GC - General Commercial District
- MU - Mixed-Use District
- UC - Urban Core District
- GI - General Industry
To verify what the zoning classification of a particular property is, contact the Zoning Office or submit a zoning confirmation request form. A setback is the distance from the property line to the structure. All commercial and industrial districts have front, side, and rear yard setbacks. Corner lots may have additional setback requirements.
