Where, prior to January 1, 1977, a permit was issued and expressly made subject to recorded terms and conditions that are not dedications of land or interests in land for the benefit of the public or a public agency pursuant to the California Coastal Zone Conservation Act of 1972 (commencing with Section 27000), the owner of real property which is the subject of such permit may apply for modification or elimination of the recordation of such terms and conditions pursuant to the provisions of this division. Such application shall be made in the same manner as a permit application. In no event, however, shall such a modification or elimination of recordation result in the imposition of terms or conditions which are more restrictive than those imposed at the time of the initial grant of the permit. Unless modified or deleted pursuant to this section, any condition imposed on a permit issued pursuant to the former California Coastal Zone Conservation Act of 1972 (commencing with Section 27000) shall remain in full force and effect.
