A critical dates calendar template for tracking all action-required dates in a commercial lease, including option notice deadlines, rent escalation dates, CAM reconciliation windows, audit deadlines, and lease expiration. This template is the foundation of a lease administration system and the single most important tool for avoiding costly missed deadlines.

Used by lease administrators, property managers, and corporate real estate teams to maintain an ongoing calendar of all lease-driven deadlines across a portfolio, with advance notice triggers for each date.
Lextract automatically extracts these fields from your lease PDF - eliminating the manual data collection underlying this checklist.
For renewal and termination options, set three alerts: 18 months out (to begin market research), 12 months out (to make a strategic decision), and 6 months out (final notice preparation). The 6-month alert should be a hard deadline reminder with sufficient time to prepare and serve notice via the required method (often certified mail with a delivery confirmation period).
Enterprise portfolios typically use dedicated lease administration software (Visual Lease, LeaseQuery, TRIRIGA) that automatically generates critical dates from abstracted lease data. For smaller portfolios, Excel-based systems are common. The key is ensuring critical dates are extracted accurately from the lease abstract - garbage in, garbage out.
Missing a renewal option notice deadline is typically the most financially damaging, as it can force a tenant to relocate at significant cost or accept unfavorable holdover terms. Missing CAM audit windows is the second most costly, as tenants lose the right to recover overbillings - potentially tens of thousands of dollars in larger leases.
