Our parcel data and other layers available for download at the Iowa GIS Data Repository. That link is: https://www.iowagisdata.org. You must register with an account and password but data is free to download from us. Note that other counties use this site to redistribute their GIS data. Some counties charge for data, but Scott County does not.
Feel free to contact us if you have any questions about the data or accessing it through the repository.
