No land shall be occupied or used and no buildings hereafter placed, erected or altered 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 Construction Official stating that the use of the building therein specified, or either of them as the case may be, complies with all the provisions of this chapter or any other ordinance of this Borough applicable to its issuance. Such certificates of occupancy shall be granted or denied within 10 days after the written application therefor has been received by the Construction Official. Applications shall be filed in duplicate by the owner or his agent and shall state the intended use of the structure and of the land. The application shall be accompanied by detailed plans and specifications, a plot plan, the established building lines within the site and such other information as may be necessary or desirable to provide for the enforcement of this chapter. Plans shall be drawn to scale and shall show actual dimensions in figures. All building plans, specifications and plot plans shall be signed by an architect or professional engineer licensed by the State of New Jersey. The owner may sign the building plans as to single-family dwellings or as to building accessories to the dwellings in the event the owner has prepared the building plans, provided the owner files an affidavit to that effect in accordance with law. Notwithstanding any other provisions of this chapter, only a land surveyor licensed by the State of New Jersey may prepare and certify the required plot plan.
