Assessor's Office

Valuing Property

The Assessor’s Office establishes values every two years for more than 120,000 properties, worth nearly $50 billion in market value. The agency uses tools such as geographic information systems (GIS) and mass appraisal techniques to perform appraisal analysis.

The Assessor discovers and lists information about properties and uses this information to determine property values.
