USGBC publishes LEED v4/v4.1 transition deadlines: registration closes June 30, 2026 (most systems) and certification sunset June 30, 2032; exceptions extend some registration windows

USGBC’s LEED certification deadlines page consolidates phase-out timelines for LEED v4 and v4.1, including the registration close date (June 30, 2026 for most BD+C/ID+C/O+M systems) and certification sunset (June 30, 2032). The page also notes specific exceptions (e.g., certain LEED v4.1 O+M recertification/interiors registration through June 30, 2027; additional exceptions for campus/master site and volume pathways). Organizations with contractual or policy commitments tied to LEED v4/v4.1 should update internal schedules for project registration and long-range certification planning to avoid missing eligibility windows.
