Elevator certificates — expired by a day, cited like a crime

The elevator's current inspection certificate needs to be posted and in date, and there is no grace period in the inspector's book. One day expired reads exactly like one year. How do you track certificate renewals against your inspection vendor's schedule — and has a PHA or owner rep ever caught it before the inspector did?

The certificate is the purest paperwork deficiency there is: the elevator can be perfectly maintained, freshly serviced, and safe in every mechanical way, and an expired date on the wall still writes the same cite as a neglected one. The fix is a tracking habit, not a repair. Put the renewal date somewhere it nags you two cycles ahead, not two days after. Who tracks your elevator certificate dates — a calendar somebody owns, your vendor, or whoever happens to notice first?
