Data sources and attribution

ZoneNotice LLC, an Oregon limited liability company · Last updated 20 September 2026

Everything in ZoneNotice comes from a public source. This page names them, credits them, and is honest about what each one can and cannot tell you.

Permit and land-use filings

Collected every weekday from the published records of Oregon cities, counties and state agencies — their own websites, their public map services, and their open-data portals. Coverage and currency vary by jurisdiction: some publish daily, some sporadically, and the fields each one publishes differ.

Plan amendment and zone change notices come from the Oregon Department of Land Conservation and Development (DLCD) post-acknowledgement plan amendment notices.

Contractor licences

Oregon Construction Contractors Board — the public register of active contractor licences, published through data.oregon.gov and reloaded regularly. Where we show a contractor's phone number or office address it usually comes from this register rather than from the filing.

A licence number shown against a filing is the number the jurisdiction published. Check it against the CCB's own register before relying on it.

Zoning

The statewide compilation is a normalised view built at a point in time. A local designation, where we can get one, comes from the jurisdiction itself. Neither is a zoning verification — ask the planning department.

Hazards and the natural environment

Parcels and boundaries

Parcel geometry and assessor attributes are maintained by each county on its own schedule. Parcel lines are not a survey and must not be treated as one. The same is true of the township, section and land claim lines: BLM publishes them as reference data, not as legal documents or land surveys, and ZoneNotice's use of them is not endorsed by BLM. State highway centerlines are ODOT's, for information only; ZoneNotice does not draw the highway right-of-way, and links to ODOT's own scanned right-of-way maps instead.

Utility lines

Utility mains are shown only where a utility publishes them, and each one is credited wherever it appears. "On screen only" means they appear on the map and parcel card but not in downloaded files, because that publisher's terms do not cover redistribution; a downloaded file says which mains it leaves out. They are approximate and are not a locate: before any digging, call 811 and verify with the utility. Where no line is drawn, the utility has not published one, which does not mean there is no pipe.

Addresses and maps

Supplementary commercial data

Where enabled, some construction filings are supplemented with contractor and job-value information from Shovels, a commercial aggregator. Supplemented values never overwrite what a jurisdiction published, and this data is excluded from customer exports under our licence with them.

How current any of this is

We check active jurisdictions every weekday, but a record only reaches us once the jurisdiction publishes it, and publication lag varies from hours to weeks. Map layers are refreshed on their publishers' schedules, which for some statewide compilations means years between versions. Where a layer carries a vintage, we store and show it.

Some jurisdictions publish nothing machine-readable, and a few block automated access to their sites. Those gaps are real and we do not paper over them.

Corrections

If a record here is wrong, the jurisdiction's own copy governs, and correcting it at the source is what fixes it everywhere. Tell us anyway at support@zonenotice.com — we will check whether the error is ours and point you at the right office if it is not.

If you are named in a record and want it reviewed, see the Privacy Policy.
