County Profiles Do Not Approve Parcels
This profile summarizes county-level signals. Before relying on a parcel, verify current rules with planning, zoning, building, environmental health, water, road, fire, title, and local professionals.
Jurisdiction note
Start With The County, Then Verify The Parcel
Oregon county profiles compare broad alternative-living signals. A parcel can still be controlled by a municipality, subdivision, HOA, utility district, floodplain, road-access issue, water limitation, septic constraint, or current local rules.

- Check zoning, building, health, water, and road offices

How to read this profile
Use The Score To Shortlist, Then Verify Locally
This page is designed to help you decide whether Multnomah County is worth deeper research. The profile is not legal advice and should not be treated as parcel approval.
Sourced discovery profile
County-level sourced discovery profile has useful official or public sources, but parcel decisions still require local due diligence.
Check the parcel before acting
Start with Verify jurisdiction, zoning district, urban growth boundary, sanitation, utilities, water rights, legal access, floodplain, covenants, and protected resource areas. A county profile does not approve a specific property or project.
Verification queue
What Still Needs Confirmation
This sourced discovery profile has useful official or public sources, but it remains a screening tool. Treat it as a shortlist candidate, then confirm the exact parcel and intended use with current local planning and permitting sources.
Current local review path
Confirm who handles planning, subdivision, rural addressing, floodplain, permitting, and enforcement for the parcel.
Exact intended use
Check the review path for the specific structure, RV or camper occupancy plan, water source, septic path, access road, and development sequence.
Data confidence
Confidence labels describe source support. They do not approve a parcel, project, permit, well, septic system, RV stay, or dwelling.
County-level profile has stronger official source coverage, but parcel-level approval is still not confirmed.
County-level sourced discovery profile has useful official or public sources, but parcel decisions still require local due diligence.

Decision fit
Best For And Not Ideal For
A plain-English shortcut for deciding whether this county belongs on your shortlist before you spend time on parcel-level zoning, water, septic, access, and covenant checks.
- Oregon county-rule due diligence
- Portland-edge rural land screening
- This is a source-anchor pass, not a legal interpretation
- urban jurisdiction, service districts, floodplain, wildfire, and city rules may dominate parcel feasibility
- Oregon land-use answers remain local and parcel-specific, especially where farm/forest zoning, statewide goals, septic feasibility, water rights, wildfire risk, access, and private covenants apply
- RV living plans without careful county and sanitation review
Use-case conflict review required
This profile contains public notes that may conflict with one or more alternative-living plans. Treat these as early warning signals and confirm the exact parcel, jurisdiction, sanitation path, permit sequence, and current local rules before relying on the score.
- Tiny homes: low county-level score; verify rules before shortlisting.
- RV living: low county-level score; verify rules before shortlisting.

How Much Should You Rely On This Profile?
The profile status and the Freedom Score answer different questions. A high score can make a county worth researching, while source confidence tells you how much local-rule review still remains.
County-level sourced discovery profile has useful official or public sources, but parcel decisions still require local due diligence.
Profile includes county-rule or official/public source links for deeper review.
Land market, public land, broadband, and solar layers are tracked separately from legal-rule confidence.
Verify zoning district, municipality, covenants, water, septic, access, utilities, permits, and current local practice.
Important boundary: No status label means a parcel is approved for a tiny home, RV, off-grid dwelling, container home, ADU, homestead, well, septic system, driveway, or utility plan.
Pros
- Official county Land Use Planning and permit portal pages provide local anchors.
- Oregon statewide land-use, building-department, and onsite wastewater references are included
- Oregon Goal 2 and statewide land-use goals now separate statewide planning context from the county planning contact route
- Oregon Building Codes Division, DEQ onsite wastewater, and OWRD water/well resources provide additional due-diligence checkpoints
- Multnomah County keeps Land Use Planning as the local route, with Oregon Goal 2 separated as the statewide land-use checkpoint.
Cons
- This is a source-anchor pass, not a legal interpretation
- urban jurisdiction, service districts, floodplain, wildfire, and city rules may dominate parcel feasibility
- Oregon land-use answers remain local and parcel-specific, especially where farm/forest zoning, statewide goals, septic feasibility, water rights, wildfire risk, access, and private covenants apply
