On July 1, 2017 the Dallas County Assessor’s Office launched a new property search and information site that provides access to county information including property sales, assessment data, tax information and GIS mapping.   This new property search site will increase the accessibility of information to the public and provide real estate agents, abstractors and commercial businesses with an easy to use format.  Click here to preview the new site.
The previous property search site can still be accessed under "Assessor Web Legacy" until October 1,2017.


Duties of The Assessor

The primary duty and responsibility of the Assessor is to make sure all real property within his/her jurisdiction is assessed, with the exception of properties where the law provides otherwise.  This includes residential, multi-residential, commercial, industrial and agricultural classes of property.  

Real property is re-valued every two years. The effective date of the assessment is the first day of January of the current year. The assessor determines either a full or partial value for new construction and improvements depending upon their state of completion on January first of the year assessed.
