Any nonconforming use existing at the effective date of this chapter may be continued, and any existing building designed, arranged, intended or devoted to a nonconforming use may be reconstructed and structurally altered and the nonconforming use therein changed, subject to the following regulations:

Whenever a district shall hereafter be changed, any then existing nonconforming use therein may be continued or changed to a use of a similar or higher classification, provided that all other regulations governing the new use are complied with.

If any accessory building is over 1 1/2 stories high, it shall be distant at least 15 feet from all lot lines, and it shall in no case be over 2 1/2 stories or 30 feet in height.

On corner lots, accessory buildings shall be located as far as possible from all street lines while conforming to the requirements of the last above subsection.

No building shall be erected until the Building Inspector shall issue a permit certifying that the proposed building and use complies in every respect with this chapter, and all applications for such permits shall be in writing and accompanied by a plot plan in duplicate, drawn to a scale showing the actual dimensions of the lot, the dimensions of all open spaces, the setback lines observed by buildings within the block, and such other information as may be necessary to provide for the enforcement of this chapter.

Such permit shall be issued for a period of six months from the date thereof. In the event, however, of a change of the provisions of this chapter or of the map accompanying the same during such period of six months, which change or changes would prevent the issuance of such permit if then applied for, and the Building Inspector shall determine that work has not begun under such permit, he shall revoke said permit and immediately send notice of revocation thereof to the holder thereof at the address given in the application therefor. The Building Inspector is also authorized at any time during the life of such permit to revoke same if it shall satisfactorily appear to him that any material statement in or any portion of the application therefor is untrue or inaccurate. Within 10 days prior to the expiration of such permit and upon a showing of sufficient cause therefor and in the event that no changes in this chapter or in the map accompanying the same have been made to prevent it, the Building Inspector may extend the permit for a further period of six months, but such extended permit shall be liable to all of the provisions of this section and any amendment thereof to the date of such extension. A copy of this section shall be printed upon each permit or extended permit issued by the Building Inspector. Before the issuance of such building permit, there shall be paid to the Building Inspector a fee therefor of $25.

The application for such permit shall contain such information as may be required by the Building Department, including a sketch or rendering of the proposed sign. The fee for such permit shall be as fixed from time to time by the Board of Trustees.
