Oregon Crawl Space Requirements
What the state actually requires — of the work, of the contractor doing it, and of the homeowner paying for it — with the document that sets each rule named and linked. Written to be checkable rather than taken on trust, and useful whether or not you ever contact anyone through this site.
- Verifying an Oregon or Washington Contractor
How to check a CCB or L&I licence in about two minutes, what the bond and insurance behind it actually cover, what the register will not tell you, and the deadlines that decide whether you have any recourse at all.

What is not here, and why
A reference section is only as good as its honesty about its own edges. These topics were considered for this hub and are not published. Each says what is holding it back, so you know whether the gap is research, editorial priority, or a subject that cannot be answered accurately at all.
- Oregon Crawl Space Code Requirements
- Substantially covered today by /resources/closed-vs-vented-crawl-space/, which quotes the same R408 provisions. Publishing a second page on identical material would split the cluster rather than add anything. Worth building as a compact reference table — section number, requirement, source — only if it is genuinely different in form from the existing article, and worth revisiting when the 2026 ORSC takes effect.
- Oregon vs Washington: What Differs Across the Columbia
- Sources are in hand and verified — this one is ready to write, not blocked on research. Held back only so the licence-verification page can establish the section first; a comparison page is more useful once there is something to compare against. Build next.
- Energy Trust Crawl Space Incentives
- Already published, and well, at /resources/energy-trust-rebate-2026/ — every figure traced to Energy Trust form PI 320I v2026.4. This section links to it rather than duplicating it. Listed here so nobody mistakes its absence for an oversight.
- Permit Requirements for Crawl Space Work
- NOT PUBLISHABLE ACCURATELY. There is no single authority: the City of Portland, Multnomah, Washington and Clackamas counties, and Clark County WA each set their own thresholds, and the answer varies by scope within each. Nothing verified so far supports a rule a homeowner could rely on, and a page that guessed would be worse than no page — a wrong permit answer costs real money. Would need per-jurisdiction confirmation, ideally direct from each building department, before anything is written.
The standard applied here
- Primary sources only. The body that sets the rule or holds the register — not a trade association's summary of it, and not another contractor's blog.
- Editions and versions are named. Building codes and incentive schedules are revised. A citation that does not say which edition it read is not checkable.
- Verification dates are real. When a page says a source was checked on a date, it means the document was opened on that date and still said what the page reports.
- Limits are stated. Where something varies by jurisdiction or could not be confirmed, the page says so instead of generalising.
- The commercial interest is disclosed. This site earns money referring homeowners to contractors. That is a reason to read it critically, and saying so is more useful than pretending otherwise.
