# California Building Energy Benchmarking (AB 802): June 1 Filing, Penalties & SB 253 Bridge

**Short answer:** California's statewide [AB 802 Building Energy Benchmarking Program](https://www.energy.ca.gov/programs-and-topics/programs/building-energy-benchmarking-program) (Cal. Pub. Res. Code § 25402.10; 20 CCR §§ 1680–1684) requires owners of commercial and multifamily buildings **over 50,000 gross sq ft with 17 or more active utility accounts** to report whole-building energy use via ENERGY STAR Portfolio Manager every **June 1**.

Even for corporations focused on California's broader corporate rules—such as [SB 253 Scope 1–3 GHG reporting](https://bcesg.org/california-sb-253-sb-261-compliance-playbook/)—AB 802 is the operational data engine: its mandatory utility aggregation rule unlocks tenant-metered whole-building electricity and gas figures that feed directly into corporate Scope 2 inventories and local municipal audits across seven California cities.

### Statutory Status at a Glance
- **Governing Authority:** Cal. Pub. Res. Code § 25402.10 (AB 802) & CEC Regulations 20 CCR §§ 1680–1684.
- **Administering Agency:** [California Energy Commission (CEC)](https://www.energy.ca.gov/programs-and-topics/programs/building-energy-benchmarking-program).
- **Covered Threshold:** Commercial buildings (>50,000 sq ft, any account count above utility aggregation rules—generally >50k w/ 0/17+ rules per CEC account triggers) and multifamily buildings (>50,000 sq ft with ≥17 active residential/commercial utility accounts).
- **Deadline & Penalty:** Annual **June 1** filing; civil penalties of **$500–$2,000 per day** after 30-day uncured violation notice.
- **Local Exemptions:** CEC recognizes approved local programs (LA EBEWE, SF EBO, San Jose BPO, San Diego) so owners avoid redundant state reporting while complying locally.

## Threshold Nuances: The 17-Utility-Account Rule & Utility Data Rights

AB 802 pairs two legal triggers that separate multi-tenant assets from single-user campuses: a building must exceed **50,000 gross sq ft** and fall within CEC's active utility account rules (notably 17+ active utility accounts for multifamily residential, or covered commercial configurations with no residential/non-residential exceptions).

Crucially, AB 802 empowers owners against recalcitrant tenants: utilities must provide aggregated whole-building energy usage within **four weeks** of request, automatically bypassing individual tenant written authorization when a building contains at least 3 commercial accounts or 5+ residential accounts.

- **Public Transparency:** CEC publishes benchmarked Energy Use Intensity (EUI) and ENERGY STAR scores on a public database for disclosable buildings.
- **30-Day Cure Notice:** Before imposing daily fines ($500–$2,000/day), CEC issues a formal written warning granting 30 days to cure missing submissions.

| Program Element | AB 802 Rule Citation | Owner Requirement & Enforcement |

| Annual CEC Deadline | 20 CCR § 1683 | Annual June 1 ENERGY STAR Portfolio Manager submission |
| Civil Penalty Schedule | Cal. Pub. Res. Code § 25402.10(f) | $500–$2,000/day after 30-day uncured CEC notice |

## Bridge to California Local Ordinances & SB 253 Scope 2 Inventories

California does not enforce a single statewide Building Performance Standard cap yet—local cities carry the performance and audit teeth. While [CEC exempts](https://www.energy.ca.gov/programs-and-topics/programs/building-energy-benchmarking-program) properties already reporting under approved local ordinances (Los Angeles EBEWE, San Francisco EBO, San Jose BPO, and San Diego), owners inside those cities face much lower square-footage floors (10,000–20,000 sq ft) and five-year retro-commissioning or renewable electricity obligations.

Meanwhile, large corporations (>$1B revenue) subject to [California SB 253 Scope 1 and Scope 2 disclosures](https://bcesg.org/california-sb-253-first-filing-compliance-checklist/) rely on AB 802 utility aggregates to reconcile leased-building operational boundaries without double counting.

## Compliance Execution Checklist

| Step | Owner / Team | Auditable Deliverable |
| --- | --- | --- |
| 1. Local vs. CEC Check | Portfolio Lead | Verify if building sits in a CEC-exempt approved city (LA, SF, San Jose, San Diego) vs. direct CEC filing. |
| 2. Request Utility Feeds | Property Ops | Request aggregated 12-month data from IOU/POU utilities in Feb/Mar (allow 4+ weeks SLA). |
| 3. File by June 1 | Asset Mgmt | Run Portfolio Manager data quality checker and submit via annual CEC reporting link before June 1. |
| 4. Reconcile SB 253 | Corporate ESG | Map Portfolio Manager meter boundaries to corporate SB 253 Scope 2 & Cat 13 disclosures. |

## Frequently Asked Questions

### Do buildings in Los Angeles or San Francisco have to file twice for AB 802 and local ordinances?

No, provided the property complies fully with a CEC-approved local benchmarking program (including LA EBEWE, San Francisco EBO, San Jose BPO, and San Diego), CEC exempts the building from duplicate state submission—though local filing deadlines (such as May 1 in SF/SJ) differ from June 1.

### Why does AB 802 matter for California SB 253 Scope 2 compliance?

AB 802's statutory whole-building utility aggregation gives corporate tenants and building owners auditable electricity and gas totals across multi-tenant assets needed for Scope 2 and Scope 3 Category 13 GHG inventories.

### What is the penalty for ignoring a California Energy Commission AB 802 notice?

After issuing a 30-day written notice of violation, the CEC may assess administrative civil penalties ranging from $500 to $2,000 per day until compliance is demonstrated.
