3-39-21. Permits and variances.
A. When advisable to facilitate the enforcement of the Municipal Airport Zoning Law [3-39-16 to 3-39-26 NMSA 1978], a system may be established for granting permits to establish or construct new structures and other uses. In any event, before any nonconforming structure may be replaced with a taller one or any nonconforming tree allowed to grow higher or be replanted, a permit must be secured from the administrative agency authorized to administer and enforce the regulations, authorizing such replacement or change. No such permit shall be granted that would allow the structure to become a greater hazard to air navigation than it was when the applicable regulation was adopted; and whenever the administrative agency determines that nonconforming structure or tree has been abandoned or more than eighty percent torn down, destroyed, deteriorated or decayed, no permit shall be granted that would allow said structure or tree to exceed the applicable height limit or otherwise deviate from the zoning regulations. Except as indicated, all applications for permits for replacement, change or repair of nonconforming uses shall be granted.
B. Any person desiring to erect any structure, or increase the height of any structure, or permit the growth of any tree, or otherwise use his property, in violation of airport zoning regulations adopted under the Municipal Airport Zoning Law, may apply to the board of appeals, as provided in Section 3-39-22 NMSA 1978, for a variance from the zoning regulations in question. Such variance shall be allowed where a literal application or enforcement of the regulations would result in practical difficulty or unnecessary hardship and the relief granted would not be contrary to the public interest but do substantial justice and be in accordance with the spirit of the regulations.
C. In granting any permit or variance under this section, the administrative agency or board of appeals may, if it deems such action advisable to effectuate the purposes of the Municipal Airport Zoning Law, and reasonable in the circumstances, so condition such permit or variance as to require the owner of the structure or tree in question to permit the political subdivision, at its own expense, to install, operate and maintain suitable obstruction markers and obstruction lights thereon.
