Residential Appraisal


The assessment process plays an important role in local government. Equitable assessments assure property owners that they are asked to pay only their fair share of the cost of operating libraries, schools, police protection and other necessary services.

Oklahoma statutes require the County Assessor's office to annually maintain all real estate values and to physically inspect each parcel at least once every four years. Staff appraisers visit the properties and note any changes in the physical attributes. This information is stored by the assessor, updated and maintained for current and future use in the assessment process.

Purpose of Appraisals

The purpose of the appraisals generated by the Oklahoma County Assessor's office is to estimate the market value for ad valorem tax purposes only. The effective date of the appraisals is January 1 of each year.
