(a) A person who desires to construct or increase the height of a communication facility structure in violation of an order adopted by a county subject to this subchapter may apply to the commissioners court of the county for a variance from the regulation.
(b) The commissioners court may allow a variance from a regulation if the commissioners court finds that:
(1) a literal application or enforcement of the regulation would result in practical difficulty or unnecessary hardship; and
(2) the granting of the relief would:
(A) result in substantial justice being done;
(B) not be contrary to the public interest; and
(C) be in accordance with the spirit of the regulation and this subchapter.

(c) The commissioners court may impose any reasonable conditions on the variance that it considers necessary to accomplish the purposes of this subchapter.
(d) Before granting a request for a variance under this section, the county may require the applicant to prominently post an outdoor sign at the location stating that a communication facility structure is intended to be located on the premises and providing the name and business address of the applicant.
(e) The sign must be at least 24 by 36 inches in size and must be written in lettering at least two inches in size. The county in which the communication facility structure is to be located may require the sign to be in English and a language other than English if it is likely that a substantial number of the residents in the area speak a language other than English as their familiar language.
