Any encroachment existing on the effective date of the ordinance from which this division was derived, as heretofore permitted by the city, may be continued for a period of ninety (90) days from and after such effective date unless discontinued, or unless the same shall become defective and unsafe prior to the expiration of such period, in which case the same shall be removed by the owner or person permitting the erection, construction, installation, placing or maintenance of the same; provided, however, that in established business districts on such streets where the buildings are at the property line and are continuous or very closely spaced, overhanging encroachments are permitted under the following conditions:
(1) Awnings, canopies, marquees and similar installations supported wholly from the face of the building shall be permitted, providing that the edge of such encroachment be not less than three (3) feet back of the face of the curb.
(2) Advertising or other similar signs supported wholly from the front of the building shall be permitted to remain in place until such time that they become functionally or structurally obsolete; such signs shall then be removed.
(3) The replacements of encroachments, as allowed in (2) above, will not be permitted.
