Section 25:30-1-4 - Who is not required to file

(1) For mobile or temporary equipment used to construct or install a new structure or to perform routine maintenance, repairs, or replace parts of an existing structure, or for temporary structures that will be in place for less than 24 months; or

(2) To repair, replace, or alter an existing structure or change the location of an existing structure that would not result in a total structure height greater than the horizontal, conical or approach surfaces as defined in Section 25:30-1-2.

(3) Structures that exist or have an approved building permit from the local authority with jurisdiction over the property that the structure is proposed to be constructed upon, prior to October 1, 2010.

(4) Any object that would be shielded by existing structures of a permanent and substantial character or by natural terrain or topographic features of equal or greater height, and would be located in the congested area of a city, town or settlement where it is evident beyond all reasonable doubt that the structure so shielded will not adversely affect safety in air navigation. This shielding is only applicable for a tall structure permit and is not pertinent for an incompatible purpose permit.
