The area within any structure housing gaming under a nonrestricted license which may be open to public use (as distinct from that devoted to the private use of guests and exclusive of any parking area) is limited to the area existing or approved for public use on May 4, 1979. Within these limits, any external modification of the structure which requires a permit from a local government also requires approval from the Agency. The Agency shall not permit restaurants, convention facilities, showrooms or other public areas to be constructed elsewhere in the region outside the structure in order to replace areas existing or approved for public use on May 4, 1979.
