(a) If land appraised as provided by this subchapter is owned by an individual 65 years of age or older, before making a determination that a change in use of the land has occurred, the chief appraiser shall deliver a written notice to the owner stating that the chief appraiser believes a change in use of the land may have occurred.
(b) The notice must include a form on which the owner may indicate that the land remains eligible to be appraised as provided by this subchapter and a self-addressed postage prepaid envelope with instructions for returning the form to the chief appraiser.

(c) The chief appraiser shall consider the owner’s response on the form in determining whether the land remains eligible for appraisal under this subchapter.
(d) If the chief appraiser does not receive a response on or before the 60th day after the date the notice is mailed, the chief appraiser must make a reasonable effort to locate the owner and determine whether the land remains eligible to be appraised as provided by this subchapter before determining that a change in use of the land has occurred.
(e) For purposes of this section, sending an additional notice to the owner immediately after the expiration of the 60-day period prescribed by Subsection (d) by first class mail in an envelope on which is written, in all capital letters, “RETURN SERVICE REQUESTED,” or another appropriate statement directing the United States Postal Service to return the notice if it is not deliverable as addressed, or providing the additional notice in another manner that the chief appraiser determines is appropriate, constitutes a reasonable effort on the part of the chief appraiser.
