# Massachusetts Large Building Energy Reporting (LBER / 225 CMR 27.00): Thresholds & June 30 Rules

> Canonical URL: https://bcesg.org/massachusetts-large-building-energy-reporting-lber-225-cmr-27-00/
> Jurisdiction: Massachusetts | Status: Live (M.G.L. c. 25A § 20 / 225 CMR 27.00) | Reviewed: 2026-11-14

**Short answer:** Massachusetts enforces one of the nation's broadest statewide building energy-reporting thresholds under the Climate Act of 2022 ([M.G.L. c. 25A § 20](https://malegislature.gov/Laws/GeneralLaws/PartI/TitleII/Chapter25A/Section20)) and Department of Energy Resources regulation **225 CMR 27.00** ([MA DOER LBER](https://www.mass.gov/info-details/large-building-energy-reporting-225-cmr-2700)). Covered commercial, institutional, industrial, and multifamily buildings **≥20,000 gross sq ft** must track and reconcile annual whole-building energy consumption with DOER by **June 30**.

For Greater Boston owners, statewide LBER serves as the reporting baseline underneath strict local decarbonization ordinances: Boston BERDO 2.0 (≥20k sq ft / 15+ units), Cambridge BEUDO (≥25k sq ft / ≥50 units), Newton BERDO (≥20k), and Lexington BEU-D (>25k) all enforce independent municipal spring filings and active emissions limits.

### Statutory Status at a Glance
- **Governing Authority:** [M.G.L. c. 25A § 20](https://malegislature.gov/Laws/GeneralLaws/PartI/TitleII/Chapter25A/Section20) (2022 Climate Act) & [225 CMR 27.00](https://www.mass.gov/info-details/large-building-energy-reporting-225-cmr-2700).
- **Administering Agency:** Massachusetts Department of Energy Resources (DOER).
- **Covered Threshold:** Commercial, industrial, institutional, and multifamily buildings ≥20,000 gross sq ft statewide.
- **4-Step Annual Calendar:** **March 15** (exemptions) → **May 30** (utilities upload metered electric/gas/steam) → **June 30** (owner reporting) → **August 31** (verification/corrections).
- **Performance vs. Reporting Split:** Statewide LBER is reporting-only today; municipal Boston BERDO 2.0 and Cambridge BEUDO impose binding GHG limits starting 2025–2026.

## Inside DOER's Four-Date LBER Reporting Architecture

Unlike state benchmarking programs that leave owners chasing tenant meter consent, 225 CMR 27.00 places a direct statutory data-delivery duty on Massachusetts electric, gas, and steam distribution utilities. By **May 30** each year, utilities submit aggregated consumption records for covered premises directly into the DOER system.

Property owners remain legally responsible for verifying parcel coverage, submitting delivered-fuel bills (fuel oil, propane, biomass), claiming vacancies or industrial exemptions by **March 15**, completing owner submissions by **June 30**, and resolving any utility anomalies prior to **August 31**.

- **Industrial & Lab Coverage:** Because M.G.L. c. 25A § 20 includes industrial buildings ≥20,000 sq ft, Route 128 life-science labs, cold storage, and suburban manufacturing plants are swept in alongside office towers.
- **Parcel vs. Condominium Boundaries:** Multiple buildings sharing single parcels require careful gross-floor-area verification against municipal assessor records before the March 15 exemption cutoff.

| DOER Milestone Date | Responsible Party | Action Under 225 CMR 27.00 |
| --- | --- | --- |
| March 15 | Building Owner | Submit boundary, vacancy, or statutory exemption requests to DOER |
| May 30 | Utilities (Electric/Gas/Steam) | Upload aggregated whole-building energy usage for covered >=20k properties |
| June 30 | Building Owner | Complete owner energy submission (incl. delivered oil/propane & property metadata) |
| August 31 | Owner & DOER Verification | Finalize discrepancy corrections before public DOER dataset publication |

## Synchronizing Statewide LBER With Boston BERDO 2.0 & Neighboring States

Inside Boston and Cambridge, owners run two distinct calendars out of the same Portfolio Manager dataset: Cambridge BEUDO filings land on **May 1** and Boston BERDO 2.0 filings land on **May 15**—more than six weeks before Massachusetts DOER's June 30 owner deadline. Ensuring third-party data verification covers both local emissions compliance and DOER records eliminates mid-summer rework.

Northeast regional managers should track Massachusetts alongside [New Jersey's July 1 benchmarking (>25k sq ft)](https://bcesg.org/new-jersey-clean-energy-act-benchmarking-njsa-48-3-87-10/) and [NYC's May 1 LL84/LL97 stack](https://bcesg.org/local-law-97-june-30-2026-deadline-file-or-extend/).

## Compliance Execution Checklist

| Step | Owner / Team | Auditable Deliverable |
| --- | --- | --- |
| 1. DOER List Audit | Asset Mgmt | Check DOER covered-building list for every MA commercial/industrial/MF parcel >=20,000 sq ft. |
| 2. Mar 15 Exemptions | Compliance Lead | File any demolition, under-threshold, or vacancy exemption documentation prior to March 15. |
| 3. Utility Match | Facilities /Ops | Confirm May 30 utility uploads capture all meters and compile delivered heating oil/propane invoices. |
| 4. Local Overlay Sync | Sustainability | Align May 1 (Cambridge) / May 15 (Boston) filings with June 30 MA LBER owner certification. |

## Frequently Asked Questions

### Are industrial warehouses and life-science labs covered by Massachusetts LBER?

Yes. M.G.L. c. 25A § 20 and 225 CMR 27.00 explicitly include commercial, institutional, industrial, and multifamily buildings of 20,000 gross sq ft or more.

### Does Massachusetts LBER impose carbon emissions fines like Boston BERDO 2.0?

Statewide LBER is an annual energy reporting mandate overseen by DOER and does not currently levy numeric carbon-cap penalties, whereas Boston BERDO 2.0 and Cambridge BEUDO impose binding emissions limits and Alternative Compliance Payments locally.

### When must a building owner submit LBER reports to DOER?

Owner reports are due June 30 annually, following March 15 exemption filings and May 30 utility uploads, with verification/corrections closing August 31.
