Scope
Oregon Laws 2026, chapter 50 (HB 4084) amends the enterprise zone statutes so that the exemption period may not be extended for qualified property used in operating a data center, and (Section 11b) provides that, notwithstanding any other law, an eligible business firm may not be authorized under ORS 285C.140 with respect to property consisting of a data center project before the date that is 90 days after the 2027 regular legislative session adjourns sine die. The act has other economic-development provisions that are not part of this record.

Summary
Oregon HB 4084, signed on 31 March 2026 and effective 5 June 2026 as chapter 50 of 2026, restricts enterprise-zone property tax benefits for data centers. Exemption periods may no longer be extended for property used in operating a data center, and no business may be authorized for the standard enterprise-zone exemption for a data center project until 90 days after the 2027 legislative session adjourns. The act does not prohibit data centers or change other zones' benefits for other industries.
What this does not establish
- One instrument, one record: both data-center provisions of the chapter (the extension exclusion and the temporary authorization bar) are recorded here.
- The act does not define "data center project"; the end of the Section 11b bar depends on a 2027 sine die date not yet known.
- Other provisions of HB 4084 (Joint Permitting Council, fast-track permitting) are not data-center measures and are not recorded.
Unresolved questions
- When the 2027 regular session will adjourn, which sets the end of the Section 11b bar.
Relationships
Supersession means a later instrument replaces the earlier legal effect. Repeal links identify the repeal instrument and the measure it ends. A later implementation or related letter is not treated as a replacement unless the record says so.
- No related action is recorded.
