How to Find Oregon Laws and Check Whether They Are Current

To research an Oregon legal question, identify the relevant Oregon Revised Statutes (ORS), check for later legislation, and then look for administrative rules or local ordinances that also apply. A statute search is a starting point: the edition date, the property's location, and the date of the event can change which text you need.

You can browse Oregon law in Corpus or start with Corpus search. Use the State/City filter to focus your research, then verify the provisions you find against the responsible government publisher. Corpus is a research aid, not the official publisher, and its Oregon catalog listing does not establish that every provision is complete or current.

Choose the right kind of Oregon source

Different documents answer different parts of a question:

• Oregon Revised Statutes: Find statutory provisions organized into chapters and numbered sections. For example, Chapter 90 covers residential landlord and tenant matters.
• Session laws: Check the legislation that added, amended, or repealed statutory language after the edition you are reading. Oregon's 2026 amendment and repeal table connects affected ORS provisions to session-law chapters and bill numbers.
• Oregon Administrative Rules: Look for agency rules implementing or interpreting statutes. The Secretary of State provides an OAR search entry point.
• City and county sources: Check the government responsible for the location. A Portland city-code provision is a different source from an Oregon statute and is not a statewide rule.

Agency handbooks and explanatory webpages can help translate unfamiliar terminology. Follow their citations to the underlying law before relying on a summary. If a question turns on how courts have interpreted a provision, statutory text alone will not resolve it; that requires separate case-law research.

Search ordinary words first, then preserve the citation

Start with the actual issue: “rental deposit,” “landlord repair,” or “agency license.” Try a second formulation using terms found in the first useful result. “Rental deposit,” for example, may lead you to the statutory heading “security deposits; prepaid rent.”

Once you have a citation, search the citation itself. Keep its punctuation and any subsection number in your research notes. ORS 90.300 points to a particular statutory section; a general search for “Oregon deposits” can mix statutes, city requirements, and consumer explanations.

Read beyond the matching sentence. Record definitions, exclusions, cross-references, and any notes following the section. Also distinguish a table-of-contents entry from the full provision: finding the heading is not the same as reading its requirements.

Example 1: Researching an Oregon rental deposit

For a deposit question, open ORS Chapter 90 and locate ORS 90.300. The chapter also contains definitions in ORS 90.100 and exclusions in ORS 90.110. Those neighboring provisions help frame whether you are researching the correct statutory scheme.

Then add the location. For a dwelling in Portland, read Portland City Code 30.01.087, which contains additional tenant protections concerning security deposits and cross-references ORS 90.300. Its subjects include deposit amounts, handling tenant funds, condition reports, and accounting.

Do not apply that Portland section to a property elsewhere merely because both properties are in Oregon. Confirm the property's jurisdiction, the local provision's scope, and the relevant rental dates. This example identifies sources to compare; it does not determine whether a particular deduction is lawful.

Example 2: Checking a landlord-repair search against 2026 changes

Suppose a search leads to ORS 90.320. The official Chapter 90 webpage carries a 2025 edition label and a notice identifying legislative activity during the 2026 regular session. That notice matters even when the section text looks complete.

In the 2026 amendment and repeal table, ORS 90.320 is listed as amended by chapter 23, section 6, associated with SB 1523. Use that reference to locate the enacted session law and read the amendment together with its effective-date and applicability provisions.

The table is a navigation tool, not a substitute for that final reading. An amendment's existence does not, by itself, tell you which version governs an earlier repair request or a later dispute. Record the date you need the law for before choosing a version.

Example 3: Verifying an agency rule's history

For an agency licensing or compliance question, search the OAR database using the agency name and subject. Once you find a rule, save its full citation and inspect its history.

The Secretary of State explains that the official copy of an administrative rule is its Administrative Order. The published history identifies the order number, with the most recent change listed first. Filing and effective dates are distinct, so record both when they matter. See the state's guide to OARs and administrative orders.

Keep a short verification record

Before relying on a result, save:

1. The exact citation and relevant subsection.
2. The official source URL and edition or revision information.
3. Any later amendment, repeal, or rulemaking order you checked.
4. The effective date and any separate applicability language.
5. The city or county, event date, and unresolved questions.

Begin with Oregon browsing when you know the jurisdiction, or search Corpus when you know only the problem. Carry the useful citations to official sources and keep the verification record with your notes. This guide explains a research process; it is not advice on an individual legal dispute.
