California · Reviewed November 2026California AB 802 compliance, filed for you
The California Building Energy Benchmarking Program (Assembly Bill 802) requires covered buildings to report energy use every year. We gather the data, check it, and file it — usually within a week.
Who’s covered
Commercial and multifamily buildings larger than 50,000 sq ft.
Annual deadline
June 1 for the previous calendar year.
Verification
No routine third-party verification — but the program runs its own data checks, so accuracy still matters.
Penalties
Civil fines of up to $2,000 for not reporting.
What to report
All energy used by the whole building — including tenant spaces — for January 1 to December 31:
- Electricity — every meter serving the building
- Natural gas
- District steam, hot or chilled water, if you have it
- Delivered fuels (oil, diesel, propane) — all delivery receipts for the year
- On-site solar production, if any
Leave out backup generator fuel. Note any meters added or removed during the year.
Good to know
- Buildings that already report to a qualifying city program — such as Los Angeles, San Francisco, San Jose or Berkeley — are generally exempt from filing with the state.
- Utilities must provide whole-building data on request, which makes tenant-metered buildings easier to report.
- The California Energy Commission publishes the results.
What we’ll need from you
- Building address, plus any utility service addresses that differ from it
- Gross floor area for the whole building and each use (office, retail, residential…), number of units and year built
- Your California Building ID (we can look it up)
- Utility data for the full calendar year, January 1 – December 31 (usually 13 months of bills)
- If tenants pay their own utilities: whole-building (aggregated) data from the utility, or signed tenant authorization forms
- Access to your ENERGY STAR Portfolio Manager account, if you have one
- Any notice or letter you received about this law
