County records you can compare

Each county publishes its assessor data in its own format and codes. Placestack puts every county in the same fields, so a study can cover one county or fifty.

Same fields everywhere

Owners, values, sales and buildings use the same field names and units in every county.

Standard land use

Each county's land use codes map to one standard list with LBCS activity codes. The county's code stays on the record.

Whole counties

Page through every parcel in a county, or filter it by land use, value, sale date or year built.

Dated records

Every record carries the date it was last updated.
