Conducting annual fire door inspections, I noted many doors that exceed the allowable clearances. Is this primarily due to the initial installation, or is it typical for fire doors to sag due to weight and other factors?

From my inspections of health care occupancies, the following are possibilities for the door to out of the NFPA 80 standard specifications:
Since NFPA 101 has mandated fire door inspections, the standard NFPA 80 is now into the fore front here and the cost to fix or replace door assemblies may be a hardship for a number of facilities.
I have many times find the fire doors are in non-fire resistant barriers and partitions that were permitted by the building and life safety codes. I understand the IFC does not require annual fire door inspections, but NFPA 101 does. Make sure the code adopted for your building require annual fire door inspections.
The first thing I would do is assess the NFPA 101 code requirements for fire barriers and fire resistance partitions in your building for your (new or existing) occupancy classification. If the fire barriers and partitions are not required to be fire resistant by the code and you have fire door assemblies installed in them, I would check with the AHJ who enforces the NFPA 101 and request approval to remove the door labeling to prevent confusion of whether they need an annual inspection or not. If you are a hospital, I understand TJC has permitted the removal of fire door labels. You may find you have inspected many fire doors that were not required by the adopted codes.
Excerpt from the 2018 NFPA 101:
Important guidance from the Annex of NFPA 101:
Section 184.108.40.206.1 of NFPA 80 as referenced by Section 220.127.116.11.1 of NFPA 101 require 13 items be inspected during the annual visual inspection.
