A construction compliance certificate shall be obtained from the Administrative Officer before any building or structure shall be erected, reconstructed, or structurally altered to increase the exterior dimensions, height or floor area, or remodeled to increase the number of dwelling units or accommodate a change in use of the building and/or premises or part thereof. The construction compliance certificate shall state that the proposed construction complies with all provisions of these regulations, and no subsequent modifications shall be made to plans or to actual construction that would be in violation of these regulations. The construction compliance certificate shall be accompanied by a site plan drawn to scale, showing existing and proposed structures, uses, open spaces, parking and loading facilities and other features affecting the use of the property.
