Use the current timeline, not older deadline snippets
Current guidance uses a May 1 annual benchmarking deadline.
Older materials may still reflect the earlier April 1 deadline and a three-year verification cycle. For current planning, use the latest District and BEAM guidance.

Which buildings are covered now
Current District guidance says private buildings over 10,000 square feet must benchmark annually. If your building is covered, treat benchmarking as a recurring annual requirement, not a one-time filing.
What third-party verification means
Third-party verification is a separate check on the quality and completeness of your benchmarking record. It does not replace annual reporting. It raises the importance of having cleaner data, clear documentation, and a benchmark that can stand up to review.
Why verification readiness matters now
Do not wait until a verification year to start cleaning up the record. The easiest way to prepare for third-party verification is to build a cleaner annual process now.
- Clearer building setup.
- Better documentation of assumptions.
- Fewer unresolved data issues at filing time.
- Less dependence on deadline-week cleanup.
A practical 90 / 30 / 7 day checklist
90 days before filing
- Confirm the building is covered and who owns the reporting task.
- Set up or review the property record and utility account coverage.
- Start gathering any missing energy or water data.
30 days before filing
- Review missing periods, outliers, and inconsistent building details.
- Resolve open questions and document any unusual values.
- Make sure the Portfolio Manager record is ready for final review.
7 days before filing
- Finish the final check.
- Confirm the benchmark is complete and ready to report.
- Make sure the record is clear enough to answer follow-up questions.
Where owners lose time
- Starting too late to fix missing utility periods.
- Finding building record inconsistencies during the final week.
- Leaving unusual values undocumented.
- Treating Portfolio Manager as the first place to discover data problems.
Frequently asked deadline questions
Why do some older pages still say April 1?
Some older materials reflect the prior rule. Current planning should use the May 1 annual deadline.
Does every covered building still benchmark annually?
Yes. Benchmarking is an annual requirement for covered buildings.
When is the next third-party verification due?
Current BEAM guidance says the next third-party verification is due in 2027 for calendar year 2026 data, and then every six years after.
Does third-party verification replace annual benchmarking?
No. Verification is separate. Covered buildings still need to benchmark every year.
Where does Portfolio Manager fit in?
Portfolio Manager is the reporting system. The operational work is making sure the property record and energy data are ready before reporting.
