Charleston County office lease: estimated payment true-up case study

A public-record government office case study where the pipeline surfaced a gross-up advisory on a $42,875 expense pool. The Rule 18 true-up finding from the prior pipeline run did not reproduce in the current multi-pass extraction.

Charleston County SC Lease Portal, Contract #2023-0812-FA
Total building operating expenses: $42,875
Correct tenant share at 10%: $42,875
Estimates paid during year: $36,000.00.
The pipeline produced 1 advisory finding (gross-up) but no hard overcharge findings.

What happened

Charleston County leased 5,000 square feet at 4000 Faber Place Drive under a triple-net lease with a 10% pro-rata share. Monthly CAM estimates of $3,000 added up to $36,000 paid during the year. When the 2024 reconciliation arrived, the landlord billed a $8,500 true-up. The math from the building expense ledger suggests the correct true-up is $5,283.76. The current multi-pass extraction pipeline did not extract sufficient true-up data to fire Rule 18, so only a gross-up advisory was produced.

Findings from the pipeline

Lease evidence

  • Pro-rata share fixed at 10.00% (5,000 SF / 50,000 SF).
  • Triple-net structure with annual CAM reconciliation.
  • Monthly estimates of $3,000 collected during the year.
  • True-up methodology: actual tenant share minus cumulative estimates paid.

Why this matters for your firm

Year-end true-up errors are easy to miss because tenants rarely see the building expense ledger. The landlord presents a single line showing what you owe, and most tenants pay it. The fix is straightforward: multiply total building expenses by your pro-rata share, subtract what you already paid in estimates, and compare. This case demonstrates that extraction quality directly affects detection coverage.

Recovery of past CAM overcharges depends on your specific lease terms, including any audit rights deadlines or ‘binding and conclusive’ provisions, and on applicable state law.

State statute of limitations periods apply to written contracts and range from 3 to 10 years. Your actual lookback window may be shorter based on your lease.
