Benton County, WA building permit search: Civic Access, statuses and old records

Which addresses this covers

The Benton County Building Department permits unincorporated land only: Finley, Plymouth, Paterson, Whitstran and the rural areas around Kennewick, Prosser, Benton City and West Richland. Kennewick, Richland, West Richland, Prosser and Benton City issue their own permits. A Kennewick or Prosser mailing address in the county's file belongs to land outside those cities; for a house inside Kennewick, see the Kennewick permit search guide.

Electrical permits in Washington come from the state Department of Labor & Industries, not the county, so a panel or wiring job will not show in Civic Access.

How to look up the permits on a Benton County address

1. Check the address is outside the five cities above. If it is inside one, use that city's permit office.
2. Open Civic Access and click Search in the menu bar. You do not need an account.
3. Type the street address, or the permit number from your paperwork.
4. Open each permit in the results. A new heat pump, a shop and a re-roof are separate permits.
5. Read the status and the inspection list on each one. A job with no passed final inspection is not signed off.

What the statuses mean

The county's status field is free text, so the same status can appear with typos. This is how our pages read it:

Of the permits issued August 2024 to July 2025, 66.9% were finished and 33.1% still open at our 21 October 2026 snapshot. The file has no expired status, so an old ISSUED permit may have lapsed; call the Building Department to check before you rely on it.

When the record is not online

For a file Civic Access does not show, make a public records request. The county's Public Records Request page links the Benton County Public Records Portal, a downloadable request form and a list of public records officers by department. It says the county applies chapter 42.56 RCW through chapter 5.14 of the Benton County Code (read 24 October 2026).

What our Benton County pages add

Civic Access answers "what was permitted at this address". Our Benton County page shows what gets built in the unincorporated county, from the same county records, August 2024 to July 2026:

86% of the 1,416 permits issued August 2024 to July 2026 were for homes. The permit statistics page breaks them down by year and month, and browse permits lists the rows without owner names or street addresses. To check the registration of the firm on a permit, use How to check a contractor's license in Washington.

What this does not tell you

The county fills a completion date on too few permits to time them, so we show which permits finished but not how long they took. Recent permits carry no parcel number, so we cannot place them by ZIP code. The file names a contractor on about three in four recent permits, but we do not rate or rank firms from it. A finished permit means the county closed it, not what the work cost or how well it was done.
