Every application for a building permit shall be accompanied by a plat in duplicate, drawn to scale, showing the actual dimensions of the plot to be built upon, the size of the building to be erected, the location of the building on the plot and such other information as may be necessary to provide for the enforcement of the regulations contained in this chapter. A record of such applications and plats shall be kept in the office of the Building Department.[1]

No land shall be occupied or used and no building or structure hereafter erected or altered so as to affect the front, side or rear yard thereof shall be occupied or used in whole or in part for any purpose whatsoever until a certificate of occupancy shall have been issued by the Building Official. No such certificate shall be issued unless the building and the intended use thereof or the intended use of land complies with all the provisions of this chapter. No change, extension or alteration of a nonconforming use or structure shall be made until an application for a permit to make such change, extension or alteration shall have been approved by the Building Official.

After the Building Official has issued a permit, other than occupancy or temporary permits, or after the Board has varied any provisions of this chapter, the permit so issued or the variance so granted shall lapse after the expiration of one year if no substantial construction has taken place in accordance with the plan or plans for which such permit was issued or variance granted, and a new permit or variance shall be obtained before the construction is started, except that, after notice and public hearing and a finding that the delay is due to reasonable cause and an additional fee has been paid to the Village in such amount as determined, from time to time, by resolution of the Board of Trustees, the Board of Appeals may grant an extension of such permit or variance for an additional period not exceeding one year.
