No building or structure shall be started, reconstructed, enlarged, or altered until a building permit shall be obtained from the Zoning Administrator.

The Town Council or Planning Commission may request a review of the building permit approved by the Zoning Administrator in order to determine whether the contemplated use is in accordance with the zoning in which the construction lies.

Each application for a building permit shall be accompanied by two copies of a drawing showing the size and shape of the parcel of land on which the proposed building is to be constructed; the nature of the proposed use of the building or land, and the location of such building or use with respect to the property lines of said parcel of land and to the right-of-way of any street or highway adjoining said parcel of land.

If it appears that the proposed building or use is in conformity with the provisions of this chapter, a permit shall be issued to the applicant by the Zoning Administrator, and one copy of the drawing shall be returned to the applicant with said permit.

Permits previously issued. Nothing herein contained shall require any change in the plans, construction, size or designated use of any building, structure, or part thereof for which a building permit has been granted before this chapter becomes effective.
