How to use the Polk County viewer
- Click the button above and wait for the Web AppBuilder viewer to load. Some counties show a terms screen first.
- Search by street address, owner or parcel ID if the search box offers those options.
- Click a lot on the map to read its attributes.
- Turn on aerial imagery from the basemap tool and use the layer list to add things like zoning or flood zones when they're published.
If an address search comes up empty, try the parcel number from a tax bill or deed instead, or click the lot on the map.

A note on accuracy
Online parcel lines are drawn for tax and planning use. They can be off by several feet, so use a recorded plat or a licensed surveyor for fences, setbacks or a sale.
