Oregon · every county, every city
Can you actually build on it?
A house, a manufactured home, an ADU, an RV, a barn — what an empty lot can hold depends on the kind of land it sits on, and the listing won’t tell you which. Paste the listing and find out before you make an offer.
Paste whatever the listing gave you — a Zillow or Redfin link, a street address, or a map pin. The district comes back with what could go on it.
What can I paste, and what works best?
Coordinates work best — right-click the spot in Google Maps and copy the pair, or paste the map link. An address works when it is a real street address; vacant land listed by tax lot (“TL 3700”) generally will not resolve, so find the parcel on the county assessor’s map and take coordinates from there. A Zillow or Redfin link can be pasted whole — those put the address in the link itself, so it is read from there and is worth exactly what the address is worth. A listing with no street number (“0 Example Rd”) is the tax lot case again.
The point is sent once to a mapping service, then Oregon’s statewide zoning layer is asked what district covers it. Coverage is uneven inside small cities. Nothing is stored, and no owner or property record is looked up.

The district decides, not the county — every county has land in several of these columns. Statewide law; the county’s own standards come on top. Any cell opens what it means for that kind of land.
Much rural land cannot hold a new house
Oregon zones large areas to protect farm and forest use, where new dwellings generally need a narrow statutory test. Listing sites do not tell you this.
What can go on a lot depends on the kind of land
A manufactured home a city must allow, a county may condition. An RV is not a dwelling anywhere in Oregon law. A barn is often the most available thing on farm land. "Tiny home" and "prefab" are not legal categories at all — which one you mean decides the answer.
Holding and building are taxed differently
Assessed value growth is generally capped at three percent a year, with new construction an exception — so building tends to cause a step change.
Start from a county instead
These counties have had their district codes and pathway rules read out of the county’s own development code. Each page sets out the districts, what each pathway looks like there, and when it was last checked.
The planner covers all 36 Oregon counties — the other 31 answer from statewide law and say so. See every county. Looking at a lot inside a city instead? Three state laws decide most of what can be added to it, by the city’s population — every Oregon city, by what the law requires.
