Although Section 1705.3 (item #4.3) appears to require SPECIAL INSPECTION for suspended ceiling systems and their anchorage when located in SDC "D", I'm not aware of jurisdictions that are enforcing that.
I know some of the ICC chapters are struggling with that item and most only do the typical jurisdiction inspection without asking for special inspections.
Im not sure what a special inspector would check for to tell you the truth. Beyond maybe tensile strength of the wires. The balance of the inspections can be done by the building inspector to verify materials and compliance with the approved plans.
Having the architect or engineer of record provide structural observations for suspended ceilings construciton have been discussed by some, but again, most of the designers are not willing to provide such field observations or are necessarily qualified to do so.
