How to talk to a county planning department

A county planning department administers the county’s development code — the local rules that sit on top of Oregon’s statewide land use system. They are the only people who can say what a specific parcel can be evaluated under. Not the listing agent, not the seller, not this site.

They are also not adversaries, and asking early costs you nothing. Planning staff field exactly these calls all day, and a question before an offer is far cheaper for everyone than a discovery after closing.

What they generally will not do is tell you whether a purchase is a good idea, or give you a decision on the spot for anything that requires review. Those are different things from what a route is and what it turns on, which they can tell you.

A phone opinion is guidance, not a decision. It is given quickly, from partial information, by someone who has not reviewed a file. It is genuinely useful for working out whether a parcel is worth pursuing, and it is not something to hang a purchase on.

Ask for anything that matters in writing. An email confirming which provisions apply is a different class of thing: it is on the record, it can be referred back to, and it survives staff turnover. Requesting it is routine and not an imposition.

A formal determination is different again. Some questions — lot of record status, a template dwelling test — are decisions the county makes on an application, usually for a fee. Where the answer decides whether the land is worth anything to you, that fee is generally small against what it settles.

One more thing worth knowing: land use decisions in Oregon are appealable to the Land Use Board of Appeals, which is why staff are careful about what they commit to informally. That caution is not obstruction.

The call goes to the city’s planning department rather than the county’s, and it starts from a different place. Three statewide statutes bind every Oregon city by its population — ORS 197A.425 on accessory dwellings, ORS 197A.420 on duplexes and middle housing, ORS 197.478 on manufactured and prefabricated homes — and each says what the city must allow and what it may not require. Citing the section by number is ordinary and staff will recognise it.

What to have ready is the same tax lot number, plus the district from the city’s own zoning map, which is what its code is written against. The state layer’s code is a translation of it.

What to ask for is the part the statutes leave to the city: the district’s dimensional standards, any overlay or design review on the lot, and the system development charges for a new dwelling or an added unit — inside a city those are commonly a five-figure line item that no listing mentions, and the exact figure is a matter of record.
