# Oregon Statewide Building Performance Standard (HB 3409 & OAR 330-300): Tier 1 & Tier 2 Guide

> Jurisdiction: Oregon | Status: Live (HB 3409 / ORS 469.275 / OAR 330-300) | Reviewed: 2026-11-14

**Short answer:** Oregon adopted a statewide two-tier Building Performance Standard under **HB 3409** (codified at ORS 469.275 et seq.) and finalized operational rules in [Oregon Department of Energy (ODOE) OAR Chapter 330, Division 300](https://www.oregon.gov/energy/save-energy/Pages/BPS.aspx). Modeled directly on Washington's Clean Buildings architecture, Oregon requires Tier 1 nonresidential buildings (≥35,000 sq ft) to hit Energy Use Intensity targets or investment criteria starting **June 1, 2028**, while Tier 2 commercial and institutional/multifamily properties begin mandatory reporting, EMP, and O&M compliance on **July 1, 2028**.

Crucial rule-citation note: ODOE's binding BPS rules live in [OAR 330-300](https://secure.sos.state.or.us/oard/displayDivisionRules.action?selectedDivision=7258) (not OAR 330-135), and statewide compliance runs separately from Portland's local energy reporting and [2050 carbon step-down ordinance track](https://bcesg.org/portland-building-carbon-standards-step-down-to-zero-2050/).

### Statutory Status at a Glance
- **Governing Authority:** HB 3409 (2023), ORS 469.275 et seq., and ODOE Administrative Rules [OAR 330-300](https://secure.sos.state.or.us/oard/displayDivisionRules.action?selectedDivision=7258).
- **Administering Agency:** [Oregon Department of Energy (ODOE)](https://www.oregon.gov/energy/save-energy/Pages/BPS.aspx).
- **Tier 1 (≥35,000 sq ft Nonresidential/Hotels/Motels):** EUI target (or LCCA investment criteria) + EMP + O&M due June 1, 2028 (≥200k), June 1, 2029 (90k–200k), and June 1, 2030 (35k–90k).
- **Tier 2 (20k–35k Com & ≥35k MF/Hospitals/Schools/Care):** Reporting + EMP + O&M due **July 1, 2028** (no numeric Tier 1 EUIt cap in Cycle 1).
- **Incentives Window:** ODOE Early Adopter Incentive funds support early Tier 1 & Tier 2 compliance preparation prior to 2028 enforcement.

## Tier 1 vs. Tier 2 Classification Under OAR 330-300

Understanding where an Oregon asset lands between Tier 1 and Tier 2 determines whether the owner faces capital retrofit obligations (or an LCCA investment audit) versus operational governance and energy reporting. Unlike Washington's >50,000 sq ft Tier 1 floor, Oregon pulls nonresidential buildings down to **35,000 sq ft** inside Tier 1.

Conversely, Oregon places **multifamily housing, hospitals, K-12 schools, universities, and senior care buildings ≥35,000 sq ft** into **Tier 2** alongside smaller commercial buildings (20,000–34,999 sq ft)—requiring benchmarking, an Energy Management Plan, and an O&M program without immediate EUIt caps.

- **ASHRAE Standard 100 Adaptation:** ODOE builds EUIt benchmarks by building activity type and climate zone, requiring a qualified Energy Manager to sign EMP and O&M documentation.
- **5-Year Recurring Cycles:** After initial 2028–2030 filings, covered Tier 1 & Tier 2 buildings re-verify compliance every five years.

| Oregon BPS Tier | Building Types & Square Footage | First Compliance Date & Core Duties |
| --- | --- | --- |
| Tier 1 — Largest | Nonresidential, hotels, motels >=200,000 sq ft | June 1, 2028 — EUIt / LCCA + EMP + O&M |
| Tier 1 — Mid | Nonresidential, hotels, motels 90,000–199,999 sq ft | June 1, 2029 — EUIt / LCCA + EMP + O&M |
| Tier 1 — Base | Nonresidential, hotels, motels 35,000–89,999 sq ft | June 1, 2030 — EUIt / LCCA + EMP + O&M |
| Tier 2 — Com & Inst/MF | Commercial 20k–35k sq ft; MF/hospitals/schools >=35k | July 1, 2028 — Energy reporting + EMP + O&M |

## Pacific Northwest Portfolio Alignment: Oregon, Washington & Portland

For commercial real estate portfolios spanning I-5 from Seattle to Portland, Oregon's OAR 330-300 deliberately tracks [Washington's CBPS (WAC 194-50)](https://bcesg.org/washington-clean-buildings-performance-standard-cbps-guide/)—allowing engineering teams to reuse Energy Management Plan templates and O&M manuals with Oregon-specific EUIt tables.

Inside Portland city limits, owners must also track **Portland City Code Chapter 17.104** (annual April 22 energy reporting for commercial buildings ≥20,000 sq ft) alongside the city's [2050 building carbon step-down policy](https://bcesg.org/portland-building-carbon-standards-step-down-to-zero-2050/). Waiting until 2028 leaves insufficient time for a mandatory 12-month metered O&M baseline.

## Compliance Execution Checklist

| Step | Owner / Team | Auditable Deliverable |
| --- | --- | --- |
| 1. Tier Verification | Asset Mgmt | Classify each OR property >=20,000 sq ft under Tier 1 (>=35k nonres) vs Tier 2 under OAR 330-300. |
| 2. Incentive Screen | Finance / ESG | Check ODOE Early Adopter Incentive eligibility before 2028 funding windows close. |
| 3. EMP & O&M Build | Operations | Stand up written EMP and 12 months of logged preventive O&M records at least 18 months pre-deadline. |
| 4. Portland Sync | Compliance Lead | Pair statewide ODOE preparation with Portland April 22 Ch. 17.104 annual Portfolio Manager filings. |

## Frequently Asked Questions

### Where are Oregon's binding BPS rules codified?

Oregon Department of Energy (ODOE) implements HB 3409 (ORS 469.275 et seq.) inside Oregon Administrative Rules Chapter 330, Division 300 (OAR 330-300).

### Are Oregon multifamily buildings subject to numeric Tier 1 EUI caps?

No. Multifamily residential buildings of 35,000 sq ft or larger fall under Tier 2, requiring energy use reporting, an Energy Management Plan (EMP), and an O&M program starting July 1, 2028.

### Does complying with Portland Ch. 17.104 satisfy Oregon HB 3409?

No. Portland City Code Chapter 17.104 governs annual April 22 commercial energy reporting in Portland, whereas OAR 330-300 enforces statewide Tier 1 EUIt targets and Tier 2 EMP/O&M governance through ODOE.
