All the members of the Washington State House of Representatives are elected concurrently with half of the senators every two years.

24 seats were regularly scheduled to be up this cycle, along with 1 additional seat holding a special election to fill an unexpired term: the 28th district, held by appointed Senator Steve O'Ban, whose former incumbent Mike Carrell vacated the seat.
