Field Appraisal


The Natrona County Assessor's Office is required by law to annually list, value and assess all taxable property in the county. This task is accomplished by the Natrona County Assessor's field appraisers.


Field Appraisers have the task of listing and valuing all real property in Natrona County for the purpose of determining market value pursuant to Wyoming Statute 39-1-102b Section 3(d.).

Field Appraisers follow-up on any building permit filed in Natrona County. They visit the property to acquire accurate information regarding the structure(s) being built.

They also confirm demolition permits. If you demolish a structure on your property, please advise the Assessor's Office so we can update the listing.

Contact our office if you have any questions at (307) 235-9444.
